Pilot study of patron sound level exposure in loud restaurants, bars, and clubs in New York city

ABSTRACTVisiting restaurants, bars, clubs, and lounges is a regular part of urban cultural life for residents and tourists alike; however, anecdotal reports and diner surveys suggest that sound levels are excessive and diners dislike them. High sound levels in these venues can contribute to both patron and employee overexposure, and young people may be particularly at risk. To supplement the paucity of literature and data on noise in urban venues, patron noise exposure was measured inside a sample of loud New York City restaurants, bars, clubs, and lounges. Sound level measurements were obtained in 59 venues. Field staff conducted one 20–162 minute visit per venue on a Thursday, Friday, or Saturday evening. The equivalent continuous sound pressure level on the A-scale (LAeq) was calculated for each visit. Median and mean LAeq among all venues sampled were both 92 decibels (dBA). Clubs and lounges had a higher mean LAeq than restaurants and bars (97 vs. 91 dBA, p < 0.05). A greater number of patrons was associated with a higher LAeq. Higher LAeq values were observed during later hours of the evening (9 PM and later). For 80% (N = 47) of the venues, the LAeq was above 85 dBA. In 49% (N = 29) of the venues, the visit exceeded the maximum allowable daily noise dose based on National Institute of Occupational Safety and Health (NIOSH) Recommended Exposure Limit (REL) of 85 dBA 8-hr Time-Weighted Average (TWA). Venues should assess indoor sound levels including employee exposure and aim to maintain sound levels that are within NIOSH guidelines.

Metal Exposures at three U.S. electronic scrap recycling facilities

ABSTRACTMany metals found in electronic scrap are known to cause serious health effects, including but not limited to cancer and respiratory, neurologic, renal, and reproductive damage. The National Institute for Occupational Safety and Health, Centers for Disease Control and Prevention performed three health hazard evaluations at electronic scrap recycling facilities in the U.S. to characterize employee exposure to metals and recommend control strategies to reduce these exposures. We performed air, surface, and biological monitoring for metals. We found one overexposure to lead and two overexposures to cadmium. We found metals on non-production surfaces, and the skin and clothing of workers before they left work in all of the facilities. We also found some elevated blood lead levels (above 10 micrograms per deciliter), however no employees at any facility had detectable mercury in their urine or exceeded 34% of the OELs for blood or urine cadmium. This article focuses on sampling results for lead, cadmium, mercury, and indium. We provided recommendations for improving local exhaust ventilation, reducing the recirculation of potentially contaminated air, using respirators until exposures are controlled, and reducing the migration of contaminants from production to non-production areas. We also recommended ways for employees to prevent taking home metal dust by using work uniforms laundered on-site, storing personal and work items in separate lockers, and using washing facilities equipped with lead-removing cleaning products.

Exposure to biological and chemical agents at biomass power plants

The increasing use and production of bioenergy means that the number of employees working in this area will inevitably grow, making it ever more important to know the health and safety issues involved in the biomass supply chain. Our aim was to determine the exposure of employees to biological and chemical agents during various work tasks at different biomass-fuelled power plants in Finland. The study included technical surveys on biomass operations and occupational measurements at three CHP plants. Workers’ main health risks were bacteria and fungi, which were easily spread to the air during heavy biomass processes. The exposure levels of actinobacteria, bacterial endotoxins and fungi were high, especially during the unloading of peat and wood chips. In addition, workers were exposed to mechanical irritation caused by organic dust, and chemical irritation caused by volatile organic compounds and components of diesel exhausts. Multiple exposures to these agents may simultaneously have synergistic health effects on workers’ lower and upper respiratory tracts. During operations, workers were also exposed to endotoxins, actinobacteria and fungi, especially during the cleaning and handling of wood chips in silos and while working near screens or crushers. The measured concentrations exceeded the limit values proposed for these agents. The highest concentration of volatile organic compounds was found near conveyors. On the basis of these measurements, we suggested best practices for the power plants. The levels of biological agents in outdoor measurements reflected only low spreading of contaminants from power plants to the environment.

Insurance and reinsurance in theFairchildenclave

The dreadful disease of mesothelioma, caused by exposure to asbestos, has a number of features that pose almost intractable problems for tort law and liability insurance, notably the time lag of some 35 years between exposure and injury, and the accepted current impossibility of science proving exactly which exposure has given rise to the disease. The Supreme Court has addressed tort and insurance issues on no fewer than six occasions, most recently inZurich Insurance PLC UK Branch v International Energy Group Ltd (IEG), a case in which a specially convened seven-judge panel split 4:3 on the correct analysis of the insurance position. This paper analyses the reasoning and its implications. As will be seen,IEGis unlikely to be the end of the story. Most of the cases have involved exposure of employees to asbestos, and discussion is directed primarily to that context. A brief outline of the authorities will suffice to set the background toIEG.

The logic of public organizations’ social media use: Toward a theory of ‘social mediatization’

The study aims to explore government agencies’ social media use. Inspired by the notion of mediatization, we ask whether it is possible to find traces of a corresponding emerging social media logic with the propensity to challenge established organizational practices and processes. In doing so, we use a modified framework originally developed by Van Dijck and Poell which identifies key three characteristics of social media logics: programmability, popularity, and connectivity. We conducted a qualitative interview study using an abductive and hermeneutist-inspired methodology. The empirical material consists of 21 interviews with representatives of Swedish government agencies. The findings reveal patterns across the organizations studied which can be understood as an emerging social media logic. Regarding connectivity, the social media logic causes agencies to spend resources on channels that engage relatively few people who are already favorably disposed toward the agency, despite government agencies’ obligation to communicate with citizens at large. Programmability refers to agencies’ increased communicative and image-building power. Finally, popularity leads agencies to engage in more personalized communication, which includes exposure of individual employees as well as use of informal communicative styles. Taken together, these categories have important ramifications which risk jeopardizing agencies’ legal and normative foundations.

Exposure assessment, a preventive process in managing workplace safety and health, challenges in Ghana

Exposure assessment is a strategy for anticipating, recognizing and evaluating employee exposures to physical, chemical, biological and ergonomic stresses at the workplace, so that effective and “sensible” controls can be put in place to mitigate the risk of occupational injury or occupational illness to the worker. It has been unveiled by this paper that this process is not applied adequately in Ghana and hence, hazards are not properly identified at workplaces. This leads to misapplication of controls or application of inadequate controls which tend not to reduce the risks at workplace. This outlines the various applicable exposure assessment strategies and also recommend controls and conditions that will make the process work in Ghana. It was outlined also that the process starts with the basic characterization which included area characterization, agent characterization and workforce characterization. This helps the industrial safety professional to understand the Similar Exposure Groupings (SEG’s) and their corresponding exposure profiles. This makes use of the basic statistics of the sample sizes of the SEG’s which get projected to the populations with 95% confidence interval so as to finalize tolerable risks. The modern engineer, the medic, and all relevant professionals must be conversant with this process and hence apply it at the workplace to ensure prevention of adverse exposures to employees, as well as prevention of accidents at the workplace.

Airborne Nanoparticles Filtration by Means of Cellulose Nanofibril Based Materials

Nanoparticles in air are of particular concern for public health and employee exposure in work-places. Therefore, it is very important to prepare effective filters for their removal. In this work filters were prepared from nanocellulose, i.e. cellulose nanofibrils (CNF). CNF was produced using two methods giving two different qualities of CNF. One quality had negative charges on the fibril surfaces while the other was neutral, and had in addition thinner fibrils compared to the other qualities. Filter samples were produced from water dispersions of CNF, by removal of the water by freeze drying. The performance of the CNF based filters was assessed and compared with filters based on synthetic polymer fibres. The ability to collect NaCl particles with a broad size distribution, ranging from nanometer to micrometer scale, was determined. CNF filters showed quality values comparable with the synthetic polymer based filters. Filters based on both the two CNF qualities had very good filtration efficiency for a given pressure drop across the filter.

Personal monitoring of ozone exposure: A fully portable device for under $150 USD cost

An inexpensive and portable device for monitoring personal ozone exposure is described and its performance characterized. The device is built from commercially available components, exhibits time resolution of approx. 60s, and highest analytical sensitivity under 100ppbv ozone. The sensor has been employed to provide insights into ozone exposure for 8 volunteers living in Lubbock, Texas during the winter months of 2015. Consistent with previous literature, the results indicate the volunteers were exposed to highest levels of ozone when outdoors during daylight hours. Exposure to ozone indoors was typically only a fraction (0.3–0.7) of the dose observed during times spent outdoors. The sensing system described requires minimal technical skills to assemble and use at a cost of approximately $150 USD per unit (see Table 1). The device's batteries provide power for 8–10h on a single charge and the sensor can be re-used many times after recharging the battery pack. A major advantage of the sensor over chromogenic filters for exposure monitoring is the collection of time-series data that allows users to better understand when and where individuals are exposed to highest ozone concentrations. The device may prove useful for industries requiring a low-cost solution to monitor employee exposure to ozone for specific work environments.

A National Study on Nurses' Exposure to Occupational Violence in Lebanon: Prevalence, Consequences and Associated Factors.

BackgroundHealthcare institutions have commonly reported exposure of employees, particularly nurses, to high levels of occupational violence. Despite such evidence in the Middle East Region, there is a dearth of national studies that have systematically investigated this phenomenon. This study investigates the prevalence, characteristics, consequences and factors associated with nurses’ exposure to occupational violence in Lebanon.MethodsA cross-sectional design was utilized to survey a nationally representative sample of 915 nurses registered with the Order of Nurses in Lebanon. Stratified random sampling by governorate was utilized. Individually-mailed questionnaires collected information on exposure to violence, degree of burnout and demographic/professional background. The main outcome variables were exposure to verbal abuse (never, 1–3, 4–9 and 10+ times) and physical violence (never, ever) over the past 12-months. Descriptive statistics were used to estimate prevalence of violence. Multivariable, binomial and multinomial regression models were carried out to investigate the correlates of exposure to verbal abuse and physical violence, respectively.ResultsResponse rate was 64.8%. Over the last year, prevalence of nurses’ exposure to verbal abuse was 62%, (CI: 58–65%) and physical violence was 10%, (CI: 8–13%). Among respondents, 31.7% of nurses indicated likelihood to quit their jobs and 22.3% were undetermined. Furthermore, 54.1% reported high levels of emotional exhaustion and 28.8% reported high levels of depersonalization. Compared to nurses with no exposure to verbal abuse, nurses reporting high exposure had high levels of emotional exhaustion (OR:6.4; CI:1.76–23.32), depersonalization (OR:6.8; CI: 3–15) and intention to quit job (OR:3.9; CI: 1.8–8.3). They further reported absence of anti-violence policies at their institutions (OR: 3; CI: 1.5–6.3). Nurses that were ever exposed to physical violence were more likely to be males (OR: 2.2; CI: 1.1–4.3), working day and night shifts (OR: 2.8; CI: 1.4–5.5) and subject to ten or more incidents of verbal abuse per year (OR: 46.7; CI: 10.1–214).ConclusionsAn alarming two-thirds of respondents reported exposure to verbal abuse which was found to be a significant predictor of the three subscales of burnout, intention to quit and exposure to physical violence. The prevalence of exposure to physical violence is disconcerting due to its severe consequences. Policy and decision-makers are urged to use study findings for policy and practice interventions to create safe work environments conducive to nurses’ productivity and retention.

New aspects from legislation, guidelines and safety standards for MRI

Many aspects of magnetic resonance (MR) operation are not directly regulated by law but in standards, guidelines and the operating instructions of the MR scanner. The mandatory contents of the operating instructions are regulated in a central standard of the International Electrotechnical Commission (IEC) 60601-2-33. In this standard, the application of static magnetic fields in MRI up to 8 Tesla (T) in the clinical routine (first level controlled mode) has recently been approved. Furthermore, the equally necessary CE certification of ultra-high field scanners (7-8 T) in Europe is expected for future devices. The existing installations will not be automatically certified but will retain their experimental status. The current extension of IEC 60601-2-33 introduces a new add-on option, the so-called fixed parameter option (FPO). This option might also be switched on in addition to the established operating modes and defines a fixed device constellation and certain parameters of the energy output of MR scanners designed to simplify the testing of patients with implants in the future.The employment of pregnant workers in an MRI environment is still not generally regulated in Europe. In parts of Germany and Austria pregnant and lactating employees were prohibited from working in the MR control zone (0.5 mT) in 2014. This is based on the mostly unresolved question of the applicability of limits for employees (exposure of extremities to static magnetic fields up to 8 T allowed) or the thresholds for the general population (maximum 400 mT). According to the European Society of Urogenital Radiology (ESUR), the discarding of breast milk after i.v. administration of gadolinium-based contrast agents in the case of a breastfeeding woman is only recommended when using contrast agents in the nephrogenic systemic fibrosis (NSF) high-risk category.

The effect of customer incivility on service employees’ customer orientation through double-mediation of surface acting and emotional exhaustion

Purpose– The purpose of this paper is to examine how customer incivility affects service employees’ emotional labor (i.e. surface acting) and the way surface acting augments their emotional exhaustion at work, and in turn, damages customer orientations of service employees.Design/methodology/approach– Using a sample of 309 department store sales employees in South Korea, a two-stage mediation model is used in terms of structural equation modeling.Findings– The results indicate that customer incivility is positively related to service employees’ use of surface acting; this, in turn, results in feelings of emotional exhaustion, which are negatively related to their customer orientation. That is, the findings of this study shows that the negative relationship between customer incivility and service employees’ customer orientation was fully and sequentially mediated by service employees’ surface acting and emotional exhaustion.Research limitations/implications– The main limitation is the nature of the cross-sectional data the authors used in the analysis. It gives us reason to be very cautious in reaching conclusions concerning causal relationships among variables, since the authors did not capture longitudinal variation.Practical implications– The research shows that customer incivility has a negative effect on service employees’ customer-oriented behaviors since experiences of customer incivility among emotionally exhausted employees via surface acting generates inadequate and unfair sense-making related to the treatment offered by customers, which increases the tendency of decreasing their effort and loyalty for customers to prevent further loss of emotional resources. Therefore, service organizations should devise appropriate strategies and implement systematic programs for reducing employee exposure to customer incivility, or preventing it altogether.Originality/value– The current study broadens the conceptual work and empirical studies in customer incivility literature by representing a fundamental mechanism of why customer incivility negatively affects service employees’ customer orientation. The primary contribution of the study is to gain a deeper understanding of how customer incivility leads to lower employee customer-oriented behaviors through double mediating effects of surface acting and emotional exhaustion.

작업환경측정 결과를 활용한 벤젠 노출 매트릭스에 대한 연구

Objectives: The aims of this study were to set up benzene exposure matrices according to industry and process and to assess the risk of those occupational exposure to benzene. Methods: The benzene exposure matrices were assembled depending on industry and process, based on an exposure database provided by KOSHA(the Korean Occupational Safety and Health Agency), which was gathered from a workplace hazards evaluation program in Korea. These exposure matrices were assessed by Hallmark Risk Assessment tool. Results: The benzene was treated 412 industries sector(36%), 2,747 business places, and 471 industrial processes according to database. The arithmetic mean of past decade 8 hours time-weighted average of airborne benzene concentrations in the workplace was 0.10722 ppm. 1.07% of the total sample were greater than OEL, and 59.8% were showed less than the limit of detection. The highest risk values(Danger Value) were seen 36 industries including manufacture of general paints and similar product and 12 processes, such as other painting of manufacture of metal fabricated members. Exposure matrices based on employee exposure data base may provide exposure histories and can be used in epidemiological studies. Conclusions: It was found that more attentions should be paid to 36 among 412 industries and 12 of 471 processes, with a higher risk value.

Occupational Noise Exposure of Employees at Locally-Owned Restaurants in a College Town

While many restaurant employees work in loud environments, in both dining and food preparation areas, little is known about worker exposures to noise. The risk of hearing loss to millions of food service workers around the country is unknown. This study evaluated full-shift noise exposure to workers at six locally-owned restaurants to examine risk factors associated with noise exposures during the day shift. Participants included cooks, counter attendants, bartenders, and waiters at full-service restaurants with bar service and at limited-service restaurants that provided counter service only. Assessments were made on weekdays and weekends, both during the summer and the fall (with a local university in session) to examine whether the time of week or year affects noise exposures to this population in a college town. In addition, the relationships between noise exposures and the type of restaurant and job classification were assessed. One-hundred eighty full-shift time-weighted average (TWA) exposures were assessed, using both Occupational Safety and Health Administration (OSHA) and National Institute for Occupational Safety and Health (NIOSH) criteria. No TWA measurements exceeded the 90 dBA OSHA 8 hr permissible exposure limit, although six projected TWAs exceeded the 85 dBA OSHA hearing conservation action limit. Using NIOSH criteria, TWAs ranged from 69–90 dBA with a mean of 80 dBA (SD = 4 dBA). Nearly 8% (14) of the exposures exceeded the NIOSH 8-hr 85 dBA. Full-shift exposures were larger for all workers in full-service restaurants (p < 0.001) and for cooks (p = 0.003), regardless of restaurant type. The fall semester (p = 0.003) and weekend (p = 0.048) exposures were louder than summer and weekdays. Multiple linear regression analysis suggested that the combination of restaurant type, job classification, and season had a significant effect on restaurant worker noise exposures (p < 0.001) in this college town. While evening/night shift exposures, where noise exposures may be anticipated to be louder, were not assessed, this study identified that restaurant type, job classification, time of week, and season significantly affected the noise exposures for day-shift workers. Intervention studies to prevent noise-induced hearing loss (NIHL) should consider these variables.

Activities and Ergonomics of Workers in Broiler Hatcheries

The objective this study was to assess ergonomic factors, posture and biomechanics of workers of a broiler egg hatchery. The analysis of ergonomic factors was based on physical work load, thermal environment, and exposure to light and noise. The posture of workers was analyzed using photographic records which were evaluated by the software program OWAS (Ovako Working Posture Analysing System). A biomechanics analysis was also performed based on the photographs taken of the employee at various angles, which were used as inputs to the Michigan two-dimensional biomechanical model software program. The results show that certain activities can be considered unhealthy due to the exposure of employees to physical and thermal overload. The continuous noise levels and lighting were outside the range considered adequate by the regulations of the Brazilian Ministry of Labor. The manner in which certain activities are carried out when associated with weight and poor posture can result in body lesions in broiler hatchery employees. It is therefore necessary to apply specific ergonomic programs, including scheduled breaks, training, and other measures in order to reduce or to eliminate the risks involved in these activities.

Vulnerability of coastal livelihoods to shrimp farming: Insights from Mozambique.

Millions of people around the world depend on shrimp aquaculture for their livelihoods. Yet, the phenomenal growth of shrimp farming has often given rise to considerable environmental and social damage. This article examines the impacts of commercial, export-oriented shrimp aquaculture on local livelihood vulnerability by comparing the exposure, sensitivity, and adaptive capacity of shrimp farm employees with non-farm employees in rural Mozambique. Exposure to stressors was similar between the two groups. Shrimp farm employees had higher assets and higher adaptive capacity than non-farm employees. However, because their income is heavily dependent on a single commodity, shrimp farm employees were highly susceptible to the boom crop nature of intensive shrimp farming. The implications for aquaculture policy and vulnerability research are discussed. The article argues that coastal vulnerability is dynamic, variable, and influenced by multiple processes operating at multiple scales.

동물병원의 진단용 방사선 발생장치 및 방사선종사자 안전관리 실태 조사

A nationwide survey on radiation safety management in Korean animal hospitals was conducted. By 2013, 53 radiation generators were registered as veterinary medical devices (41 X-ray generators and 12 computed tomography scanners). Additionally there were six approved laboratories for radiation equipment and protection facility, and five approved laboratories for radiation exposure of employees, respectively. By March 2013, 2,030 out of 3,829 animal hospitals operated radiation-generating devices. Among these devices, 389 (19.2%) out of 2,030 were not labeled with the model name and 746 (36.7%) were not labeled with production dates. Thus, most veterinary X-ray generators were outdated (42.6%) and needed replacements. When periodic inspections of 2,018 animal hospitals were performed after revision of the Veterinarians Act in 2011, the hospitals were found to be equipped with appropriate radiation generators and protection facilities. Among 2,545 employees exposed to radiation at the hospitals, 93.9% were veterinarians, 4.3% were animal nurse technicians, and 18% held other positions. Among 169 employees supervised by administrators, none of those had a weekly maximum operating load that exceeded 10 mA·min. This study suggests that the radiation safety management system of animal hospitals was general good.

Secondhand smoke exposure within semi-open air cafes and tobacco specific 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) concentrations among nonsmoking employees.

Secondhand smoke (SHS) is a defined occupational hazard. The association though between SHS exposure in semi-open air venues and tobacco specific carcinogen uptake is an area of debate. A cross sectional survey of 49 semi-open air cafes in Athens, Greece was performed during the summer of 2008, prior to the adoption of the national smoke free legislation. All venues had at least 1 entire wall open to allow for free air exchange. Indoor concentrations of particulate matter smaller than 2.5 microns (PM2.5) attributable to SHS were assessed during a work shift, while 1 non-smoking employee responsible for indoor and outdoor table service from each venue provided a post work shift urine sample for analysis of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL). Post work shift NNAL concentrations were correlated with work shift PM2.5 concentrations attributable to SHS (r = 0.376, p = 0.0076). Urinary NNAL concentrations among employees increased by 9.5%, per 10 μg/m(3) increase in PM2.5 concentrations attributable to SHS after controlling for the time of day and day of week. These results indicate that the commonly proposed practice of maintaining open sliding walls as a means of free air exchange does not lead to the elimination of employee exposure to tobacco specific carcinogens attributable to workplace SHS.

Taking it out on survivors: Submissive employees, downsizing, and abusive supervision

For the past decade, researchers' attention to abusive supervision (Tepper, 2000, Acad. Manage. J., 43, 178) has grown consistently. However, little is still known as to why certain individuals are picked by supervisors as targets for abuse. Our study tests a model of antecedents of abusive supervision, building on the profile of submissive employees (Aquino &amp; Lamertz, 2004, J. Appl. Psychol., 89, 1023) and examining the potential role played by the work context. With a sample of 193 employee–supervisor dyads from downsized and non‐downsized organizations, we found that as core self‐evaluations and coworker support decreased, abusive supervision increased, particularly in downsized organizations, and this effect carried over to both in‐role and extra‐role performance. Using a displaced aggression framework (Hoobler &amp; Brass, 2006, J. Appl. Psychol., 91, 1125), our study contributes to the discussion of the antecedents of abusive supervision by emphasizing the roles played (1) by the victim and (2) by the context in which these events take place.Practitioner points Supervisors aim their abusive behaviours at subordinates that appear particularly vulnerable and submissive. Strategies to prevent/reduce supervisory abusive behaviours in organizations should also focus on empowering subordinates themselves not just on training supervisors. Downsizings are particularly powerful triggers of abusive supervision as they enhance the vulnerability and exposure of submissive employees.

Evaluation of Glycol Ether as an Alternative to Perchloroethylene in Dry Cleaning

Perchloroethylene (PCE) is a highly utilized solvent in the dry cleaning industry because of its cleaning effectiveness and relatively low cost to consumers. According to the 2006 U.S. Census, approximately 28,000 dry cleaning operations used PCE as their principal cleaning agent. Widespread use of PCE is problematic because of its adverse impacts on human health and environmental quality. As PCE use is curtailed, effective alternatives must be analyzed for their toxicity and impacts to human health and the environment. Potential alternatives to PCE in dry cleaning include dipropylene glycol n-butyl ether (DPnB) and dipropylene glycol tert-butyl ether (DPtB), both promising to pose a relatively smaller risk. To evaluate these two alternatives to PCE, we established and scored performance criteria, including chemical toxicity, employee and customer exposure levels, impacts on the general population, costs of each system, and cleaning efficacy. The scores received for PCE were 5, 5, 3, 5, 3, and 3, respectively, and DPnB and DPtB scored 3, 1, 2, 2, 4, and 4, respectively. An aggregate sum of the performance criteria yielded a favorably low score of “16” for both DPnB and DPtB compared to “24” for PCE. We conclude that DPnB and DPtB are preferable dry cleaning agents, exhibiting reduced human toxicity and a lesser adverse impact on human health and the environment compared to PCE, with comparable capital investments, and moderately higher annual operating costs.

Highly Elevated Serum Concentrations of Perfluoroalkyl Substances in Fishery Employees from Tangxun Lake, China

Increasing production and use of per- and polyfluoroalkyl substances (PFASs) has been reported from China, and a few studies have shown there are subpopulations in China with high and increasing exposure to these chemicals. In this paper, we present a comprehensive exposure assessment of PFASs in fishery employees from Tangxun Lake, China. Exceptionally high serum concentrations of C4 to C12 PFASs were observed in fishery employees (n = 39, median perfluorooctanesulfonic acid (PFOS) 10 400 ng/mL) compared to a reference group from the same city (n = 9, median PFOS 18.7 ng/mL). On the basis of the comparison of different exposure pathways, it was concluded that contaminated fish from Tangxun Lake was the primary source of PFAS exposure to fishery employees, and there was a positive association between serum PFAS concentrations and time of employment in the fishery. PFOS isomer profiles in fishery employees showed a significantly higher proportion of linear PFOS (78.4%) compared to the background-exposed reference group (66.8%), reflecting the highly linear PFOS isomer profile (>90%) of lake fish. Median renal clearance rates (CLrenal) of C4 to C10 perfluoroalkyl carboxylic acids (PFCAs) and perfluoroalkanesulfonic acids (PFSAs) ranged from 0.020 to 16.5 mL/day/kg and 0.013 to 9.43 mL/day/kg, respectively. PFCAs with less than eight perfluoroalkyl carbons were primarily eliminated via urine, whereas other routes of excretion may have contributed to the elimination for long-chain PFCAs and PFSAs. Calculated daily PFOS exposures of fishery employees significantly exceeded tolerable daily intake limits, but clinical blood chemistry parameters were mostly within normal reference ranges. However, additional epidemiological studies are needed to address potential associations between PFAS exposure and health effects in the Tangxun Lake area.
