National and state cost savings associated with prohibiting smoking in subsidized and public housing in the United States.

IntroductionDespite progress in implementing smoke-free laws in indoor public places and workplaces, millions of Americans remain exposed to secondhand smoke at home. The nation’s 80 million multiunit housing residents, including the nearly 7 million who live in subsidized or public housing, are especially susceptible to secondhand smoke infiltration between units.MethodsWe calculated national and state costs that could have been averted in 2012 if smoking were prohibited in all US subsidized housing, including public housing: 1) secondhand smoke-related direct health care, 2) renovation of smoking-permitted units; and 3) smoking-attributable fires. Annual cost savings were calculated by using residency estimates from the Department of Housing and Urban Development and cost data reported elsewhere. Data were adjusted for inflation and variations in state costs. National and state estimates (excluding Alaska and the District of Columbia) were calculated by cost type.ResultsProhibiting smoking in subsidized housing would yield annual cost savings of $496.82 million (range, $258.96–$843.50 million), including $310.48 million ($154.14–$552.34 million) in secondhand smoke-related health care, $133.77 million ($75.24–$209.01 million) in renovation expenses, and $52.57 million ($29.57–$82.15 million) in smoking-attributable fire losses. By state, cost savings ranged from $0.58 million ($0.31–$0.94 million) in Wyoming to $124.68 million ($63.45–$216.71 million) in New York. Prohibiting smoking in public housing alone would yield cost savings of $152.91 million ($79.81–$259.28 million); by state, total cost savings ranged from $0.13 million ($0.07–$0.22 million) in Wyoming to $57.77 million ($29.41–$100.36 million) in New York.ConclusionProhibiting smoking in all US subsidized housing, including public housing, would protect health and could generate substantial societal cost savings.

Analysis and Measurements of Artificial Optical Radiation (AOR) Emitted by Lighting Sources Found in Offices

In this paper the authors describe in detail the exposure limit values concerning artificial optical radiation due to the main incoherent light sources found in offices. In particular, for some examples of significant sources chosen as case studies, we discuss the results of in situ measurements of the exposure values using a broadband photoradiometer. By comparing the measurement results with the exposure limit values specified in the European legislation, the maximum exposure times for workers have been evaluated. From the analysis of the results it can be concluded that the lighting sources typically present in indoor workplaces under usual conditions of use, do not pose a health risks for workers. However, in the case of accidental exposure during work activities or exposure linked to maintenance activities (short exposure distance), values in excess of the limit values have been observed, with decidedly short maximum exposure times.

Degree of exposure to secondhand smoking and related knowledge, attitude among adults in urban China

To identify the levels of exposure to second-hand smoking (SHS) among Chinese adults living in the urban areas and their knowledge on the risks of SHS, to support for the Smoke-free policy. Data from the Global Adult Tobacco Survey (GATS) and the International Tobacco Control Policy Evaluation China Survey (ITC China Survey) was analyzed and SAS was used to calculate the rates and 95%CI. In the two surveys, less than 40% of the respondents reported that their workplaces had completely stopped smoking. Participants who reported that they had seen people smoking at various public places with different rates, also they could reflect the levels to SHS exposure. Restaurants were the venue with the heaviest overall exposure (83.4%-95.6%), followed by the workplace (53.3%-84.0%). Exposure was low in health facilities, schools and public transport venues. In the GATS survey, 60.6% smokers and 68.5% non-smokers believed that SHS could cause lung cancer, but only one-third of the participants believed that SHS could cause heart diseases in adults. Participants in the ITC China survey reported a comparatively higher level of awareness on the harm of SHS, but only 58.2% smokers believed that SHS could cause heart diseases in adults. Overall, data from the ITC China survey showed that participants' support for a comprehensive smoke-free policy in schools, health-related facilities, government buildings and in taxi were high (over 70% ). However, the proportion of participants supporting comprehensive smoking-free policy at workplaces (50.9%-60.9%) was relatively low. The proportion of indoor workplaces with complete smoking ban was low in urban areas but levels to SHS exposure were high. People's awareness of harms related to SHS and their attitude on setting up a comprehensive smoke-free workplace need to be improved.

Evaluating the capabilities of Aerosol-to-Liquid Particle Extraction System (ALPXS)/ICP-MS for monitoring trace metals in indoor air

This study investigates the application of the Aerosol-to-Liquid Particle Extraction System (ALPXS), which uses wet electrostatic precipitation to collect airborne particles, for multi-element indoor stationary monitoring. Optimum conditions are determined for capturing airborne particles for metal determination by inductively coupled plasma–mass spectrometry (ICP-MS), for measuring field blanks, and for calculating limits of detection (LOD) and quantification (LOQ). Due to the relatively high flow rate (300 L min−1), a sampling duration of 1 hr to 2 hr was adequate to capture airborne particle-bound metals under the investigated experimental conditions. The performance of the ALPXS during a building renovation demonstrated signal-to-noise ratios appropriate for sampling airborne particles in environments with elevated metal concentrations, such as workplace settings. The ALPXS shows promise as a research tool for providing useful information on short-term variations (transient signals) and for trapping particles into aqueous solutions where needed for subsequent characterization. As the ALPXS does not provide size-specific samples, and its efficiency at different flow rates has yet to be quantified, the ALPXS would not replace standard filter-based protocols accepted for regulatory applications (e.g., exposure measurements), but rather would provide additional information if used in conjunction with filter based methods.ImplicationsThis study investigates the capability of the Aerosol-to-Liquid Particle Extraction System (ALPXS) for stationary sampling of airborne metals in indoor workplace environments, with subsequent analysis by ICP-MS. The high flow rate (300 L/min) permits a short sampling duration (< 2 hr). Results indicated that the ALPXS was capable of monitoring short-term changes in metal emissions during a renovation activity. This portable instrument may prove to be advantageous in occupational settings as a qualitative indicator of elevated concentrations of airborne metals at short time scales.

Cardiovascular Events Following Smoke-Free Legislations: An Updated Systematic Review and Meta-Analysis.

Legislations banning smoking in indoor public places and workplaces are being implemented worldwide to protect the population from secondhand smoke exposure. Several studies have reported reductions in hospitalizations for acute coronary events following the enactment of smoke-free laws. We set out to conduct a systematic review and meta-analysis of epidemiologic studies examining how legislations that ban smoking in indoor public places impact the risk of acute coronary events. We searched MEDLINE, EMBASE, and relevant bibliographies including previous systematic reviews for studies that evaluated changes in acute coronary events, following implementation of smoke-free legislations. Studies were identified through December 2013. We pooled relative risk (RR) estimates for acute coronary events comparing post- vs. pre-legislation using inverse-variance weighted random-effects models. Thirty-one studies providing estimates for 47 locations were included. The legislations were implemented between 1991 and 2010. Following the enactment of smoke-free legislations, there was a 12 % reduction in hospitalizations for acute coronary events (pooled RR: 0.88, 95 % CI: 0.85-0.90). Reductions were 14 % in locations that implemented comprehensive legislations compared to an 8 % reduction in locations that only had partial restrictions. In locations with reductions in smoking prevalence post-legislation above the mean (2.1 % reduction) there was a 14 % reduction in events compared to 10 % in locations below the mean. The RRs for acute coronary events associated with enacting smoke-free legislation were 0.87 vs. 0.89 in locations with smoking prevalence pre-legislation above and below the mean (23.1 %), and 0.87 vs. 0.89 in studies from the Americas vs. other regions. The implementation of smoke-free legislations was related to reductions in acute coronary event hospitalizations in most populations evaluated. Benefits are greater in locations with comprehensive legislations and with greater reduction in smoking prevalence post-legislation. These cardiovascular benefits reinforce the urgent need to enact and enforce smoke-free legislations that protect all citizens around the world from exposure to tobacco smoke in public places.

Exposure to secondhand smoke and attitudes toward smoke-free workplaces among employed U.S. adults: findings from the National Adult Tobacco Survey.

This study assessed the prevalence and correlates of secondhand smoke (SHS) exposure and attitudes toward smoke-free workplaces among employed U.S. adults. Data came from the 2009-2010 National Adult Tobacco Survey, a landline and cellular telephone survey of adults aged ≥18 years in the United States and the District of Columbia. National and state estimates of past 7-day workplace SHS exposure and attitudes toward indoor and outdoor smoke-free workplaces were assessed among employed adults. National estimates were calculated by sex, age, race/ethnicity, education, annual household income, sexual orientation, U.S. region, and smoking status. Among employed adults who did not smoke cigarettes, 20.4% reported past 7-day SHS exposure at their workplace (state range: 12.4% [Maine] to 30.8% [Nevada]). Nationally, prevalence of exposure was higher among males, those aged 18-44 years, non-Hispanic Blacks, Hispanics, and non-Hispanic American Indians/Alaska natives compared to non-Hispanic Whites, those with less education and income, those in the western United States, and those with no smoke-free workplace policy. Among all employed adults, 83.8% and 23.2% believed smoking should never be allowed in indoor and outdoor areas of workplaces, respectively. One-fifth of employed U.S. adult nonsmokers are exposed to SHS in the workplace, and disparities in exposure exist across states and subpopulations. Most employed adults believe indoor areas of workplaces should be smoke free, and nearly one-quarter believe outdoor areas should be smoke free. Efforts to protect employees from SHS exposure and to educate the public about the dangers of SHS and benefits of smoke-free workplaces could be beneficial.

Evaluation of hazardous airborne carbonyls on a university campus in southern China

A comprehensive assessment of indoor carbonyl compounds for the academic staff, workers, and students was conducted on a university campus in Xiamen, China. A total of 15 representative environment categories, including 12 indoor workplaces and three residential units, were selected. The potential indoor pollution sources were identified based on the variability in the molar compositions and correlation analyses for the target carbonyls. Furnishing materials, cooking emissions, and electronic equipment, such as photocopiers, can generate various carbonyls in the workplace. Comparison studies were conducted in the clerical offices, demonstrating that off-gases from wooden furniture and lacquer coatings, environmental tobacco smoke (ETS), and the use of cleaning reagents elevated the indoor carbonyl levels. The measured concentrations of formaldehyde and acetaldehyde in most locations surpassed the exposure limit levels. The lifetime cancer hazard risk (R) associated with formaldehyde was above the concern risk level (1 × 10−6) in all of the workplaces. The results indicate that formaldehyde exposure is a valid occupational health and safety concern. Wooden furniture and refurbishing materials can pose serious health threats to occupants. The information in this study could act as a basis for future indoor air quality monitoring in Mainland China.Implications:A university campus represents a microscale city environment consisting of all the working, living, and commercial needs of staff and students. The scope of this investigation covers 21 hazardous carbonyl species based on samples collected from 15 categories of workplaces and residential building in a university campus in southern China. Findings of the study provide a comprehensive assessment of indoor air quality with regards to workers’ health and safety. No similar study has been carried out in China.

The 50th Anniversary of the US Surgeon General's Report on Tobacco: What We've Accomplished and Where We Go From Here

January 11, 2014, marks the 50th anniversary of a significant milestone in our nation's public health. It was on this date in 1964 that US Surgeon General, Dr. Luther Terry, courageously released the first Surgeon General's Report on Smoking and Health.[1][1] This landmark report transformed the way

It?s Time to Move Past Smoke Free Rooms: A Proposal for Standard Hypoallergenic Hotel Rooms

In 1964 the Surgeon General released the landmark Report on Smoking and Health (1). The report and subsequent studies linked tobacco with a multitude of cardiovascular and respiratory diseases, including cancer, COPD, asthma and heart disease. Dramatic changes took place on every level of society, profoundly effecting the hospitality industry. In the US and Canada, the demands of anti- tobacco forces were at first ridiculed, then awkwardly placated, eventually becoming an expected standard. Since the publication of the 1964 report smoking rates decreased from 43% to 18% of adults (2). In 2006 the Surgeon General Report on Second Hand Smoke (3) prompted Westin Hotels to announce a chain wide, 100% smoke free hotel policy. This was soon followed by Marriott and all its brands. Soon followed by other brands in the United States and Canada. These policies were implemented voluntarily. Continuing pressure led to five states (as of 4/14/2014); Indiana, Michigan, Nebraska, North Dakota and Wisconsin and nearly 100 municipalities to mandate that hotels be 100% smoke free (4). Although many countries have smoking bans extending to all indoor public places, including restaurants, workplaces and public transport, hotels are generally not subject to such laws with the exception of Bermuda. Allergies are major cause of illness in the industrialized world, with 10 to 20% of the population suffering from symptoms induced by respiratory allergy with children and young adults making up a very significant fraction of those affected. As opposed to falling smoking rates, allergy and asthma prevalence is increasing. Asthma now effects between 5 and 10 percent of the population (5,6) with allergy being the most common exacerbating factor. Asthma and allergic diseases are some of the most common reasons for visits to health care providers and emergency rooms, resulting in significant direct and indirect costs (7). In addition to the economic burden, asthma and allergic diseases significantly impact the quality of life of sufferers (8).

Complete workplace indoor smoking ban and smoking behavior among male workers and female nonsmoking workers' husbands: a pseudo cohort study of Japanese public workers.

A pseudo cohort study using national cross-sections (2001, 2004, 2007, and 2010) was conducted to examine differences in smoking prevalence under different smoking ban policies such as a complete workplace indoor smoking ban (early or recent implementation) and a partial smoking ban among male public workers and husbands of female nonsmoking public workers. The effectiveness of smoking bans was estimated by difference-in-differences (DID) with age group stratification. The results varied considerably by age and implementation period. Although DID estimates (positive value of DID estimate represents smoking cessation percentage) for both smoking bans on total male smoking were not significant, the over-40 age group indicated a significant DID estimate of 5.0 (95% CI: 0.2, 9.8) for the recent smoking ban. For female workers' husbands' smoking, the over-40 age group indicated positive, but not significant, DID estimates for the early and recent smoking bans of 7.2 (−4.7, 19.2) and 8.4 (−2.0, 18.7), respectively. A complete indoor workplace smoking ban, particularly one recently implemented among public office workers aged over 40, may reduce male workers' smoking and female workers' husbands' smoking compared with a partial smoking ban, but the conclusion remains tentative because of methodological weaknesses in the study.

Exposure to secondhand smoke among adults – Philippines, 2009

We assessed the differences in exposure to secondhand smoke (SHS) among adults at home, in indoor workplaces, and in various public places in the Philippines across various socio-demographic groups. Data from the Global Adult Tobacco Survey conducted in 2009 in the Philippines were used. The data consist of survey answers from 9705 respondents from a nationally representative, multistage probability sample of adults aged 15 years or older. We considered that respondents were exposed to SHS if during the previous 30 days they reported that they lived in a home, worked in a building, or visited a public place where people smoked. The public places included in our analysis were indoor workplaces, public transportation vehicles, restaurants, government buildings or offices, and healthcare facilities. The differences in various socioeconomic and demographic groups' exposure to SHS in these places were also examined. Of respondents who reported working indoors, 36.8% were exposed to SHS. Men (43.3% [95% CI 39.7-46.9]) were more likely than women (28.8% [95% CI 25.4-32.4]) to be exposed to SHS (p < 0.001). Of those working in sites where smoking was not allowed, 13.9% were exposed to SHS, whereas 66.5% were exposed where smoking is allowed in some enclosed areas, and 90.7% were exposed where smoking is allowed everywhere. During the 30 days preceding the survey, more than 50% of those who took public transportation were exposed to SHS; exposure for those who visited public buildings was 33.6% in restaurants, 25.5% in government buildings or offices, and 7.6% in healthcare facilities. Despite a national law passed and several local government ordinances that have promulgated smoke-free workplaces, schools, government offices, and healthcare facilities, our findings show that a large proportion of adults were exposed to SHS at work and in public places, which offers opportunities to strengthen and improve enforcement of the smoke-free initiatives and ordinances in the Philippines.

Factors associated with parental smoking in the presence of school-aged children: a cross-sectional study

BackgroundIn 2009, the Tobacco Hazards Prevention Act (Taiwan) was amended to more effectively restrict smoking in indoor public places and workplaces in Taiwan. However, the lack of prohibitions for smoking in private homes may place family members at increased risk for exposure to environmental tobacco smoke (ETS). The aim of our study was to determine the factors associated with parental smoking in the presence of children at home.MethodsIn 2010, we performed a cross-sectional study of factors associated with parental smoking in the presence of children at home in Taiwan using self-administered questionnaires. Quota sampling was used to select five primary schools from four different regions of Taiwan. Parents were surveyed to identify parental smokers and 307 parental smokers were selected for participation in our study. Questionnaire data regarding parental smoking in the presence of children at home and related interactions among family members were analyzed. Hierarchical logistic regression was used to determine the best-fit model for examining the relationships among the variables related to parental smoking in the presence of children at home.ResultsTwo-thirds of parents who smoked reported smoking in the presence of their children. The results of the hierarchical logistic regression analysis identified the smokers’ compliance with their family’s antismoking responses, mutual agreement with smoking bans, daily smoking, smoking more than 20 cigarettes per day, the education level of the parental smoker, and the annual family income as determinants of smoking in the presence of children at home.ConclusionsHouseholds with smoking parents should be targeted for interventions to encourage the adoption and enforcement of home smoking bans. Educational interventions that promote smoke-free homes for children and provide support to help parents stop smoking are critical factors in reducing the frequency of children’s ETS exposure in the home.

ATTITUDE OF ADULT POPULATION OF THE KRASNOYARSK TERRITORY TO SMOKING BAN AT WORKPLACES

We have conducted an opinion survey among representative sample of working population of the Krasnoyarsk Territory (1000 persons aged from 18 to 60) to study their attitude to the introduction of smoking ban at workplaces. Data was collected from questionnaires and telephone interviews. The collected data suggests, that 32,7% of respondents smoke on a regular basis, 45,2% are exposed to cigarette smoke at workplaces, 67,2% of nonsmokers are passive smokers. 64,8% of respondents support the idea of smoking ban at indoor workplaces; 46,3% of respondents support imposing sanctions for violation of the ban; 52,6% of smokers are ready to smoke only outdoors or in specially allotted places. After the introduction of smoking ban at cafes, restaurants and bars 90,8% of working population will still continue visiting them or visit more often, and 16,9% of those who did not attend them before because of cigarette smoke present in the air. In the view of the working population introduction of smoking ban at indoor workplaces is essential for the preservation of the population’s health.

Detection of fluorotelomer alcohols in indoor environments and their relevance for human exposure

Fluorotelomer alcohols (FTOH) are important precursors of perfluorinated carboxylic acids (PFCA). These neutral and volatile compounds are frequently found in indoor air and may contribute to the overall human exposure to per- and polyfluorinated alkyl substances (PFAS). In this study air samples of ten workplace environments and a car interior were analysed. In addition, extracts and emissions from selected outdoor textiles were analysed in order to establish their potential contribution to the indoor levels of the above-mentioned compounds.Concentrations of FTOHs measured in air ranged from 0.15 to 46.8, 0.25 to 286, and 0.11 to 57.5ng/m3 for 6:2, 8:2 and 10:2 FTOHs, respectively. The highest concentrations in air were identified in shops selling outdoor clothing, indicating outdoor textiles to be a relevant source of FTOH in indoor workplace environments. Total amounts of FTOH in materials of outdoor textiles accounted for <0.8–7.6, 12.1–180.9 and 4.65–105.7μg/dm2 for 6:2, 8:2 and 10:2 FTOHs, respectively. Emission from selected textiles revealed emission rates of up to 494ng/h.The measured data show that a) FTOHs are present in indoor textiles (e.g. carpets), b) they are released at ambient temperatures and c) indoor air of shops selling outdoor textiles contains the highest levels of FTOH. Exposure of humans to perfluorooctanoic acid (PFOA) through absorption of FTOH and subsequent degradation is discussed on the basis of indoor air levels. Calculation of indoor air-related exposure using the median of the measured air levels revealed that exposure is on the same order of magnitude as the recently reported dietary intakes for a background-exposed population. On the basis of the 95th percentile, indoor air exposure to PFOA was estimated to exceed dietary exposure. However, indoor air-related intakes of FTOH are far below the tolerable daily intake (TDI) of PFOA, indicating that there is no risk to health, even when assuming an unrealistic complete degradation of FTOH into PFOA.

Workplace indoor radon survey in Nova Scotia, Canada

Radon is a naturally occurring gas emitted from the radioactive decay of uranium. A systematic radon assessment carried out in Nova Scotia (NS) has shown that many areas in the province are radon prone due to elevated levels of natural radioactivity in soil. Very little occupational radon data is available for NS, so this survey was designed to collect basic radon information from several NS workplaces in a nonrandomized fashion. Twenty three workplaces were contacted for participation in the study, and 21 participated for a 91% participation rate. The survey was conducted by placing 170 alpha track detectors within 21 workplaces for a minimum three-month sampling period and comparing the results with the Canadian Guidelines for the Management of Naturally Occurring Radioactive Materials (NORM) and the Health Canada Guidelines. The results indicated that 19 of the workplaces had average radon concentrations below 150 Bqm−3, with only two workplaces having at least one measurement above this concentration. Both workplaces with elevated measurements had fewer than 25 employees and a lack of mechanical ventilation. The range of results for all workplaces was from −2.0 to 202.1 Bqm−3, with an overall average of 25.7 Bqm−3 for all workplaces. Future surveys should focus on small workplaces (&lt;25 employees) with a lack of mechanical ventilation.

Workplace temperature requirements in the German Workplace Ordinance: revising the rule

The German Ordinance on Workplaces calls for a room temperature range beneficial to health. This requirement is specified in a revised version of the German Rule for Workplaces ASR A3.5 ‘Room Temperature’ applying for all kind of indoor workplaces. The former version of this rule laid down that the indoor air temperature shall not exceed 26°C (79°F). During a hot summer period with outside temperatures above 26°C, the indoor air temperature may be higher as an exception. In view of misinterpretation of this former version, the aim was to explain how to deal with a high room temperature during a hot summer period in Germany. In comparison with the former version of this rule, the revised version defines the requirements for acceptable elevated room temperatures in the latter case high outside temperatures using a step model following the principle of the adaptive approach. This article explains the need for the revision, the development of the revised version including recent scientific findings and the new rule in detail.

Attitudes Toward Smoke-Free Workplaces, Restaurants, and Bars, Casinos, and Clubs Among U.S. Adults: Findings From the 2009-2010 National Adult Tobacco Survey

An increasing number of U.S. states and communities have implemented smoke-free policies prohibiting smoking in all indoor workplaces and public areas. Public attitudes toward smoke-free environments are an evidenced-based, key indicator for the successful implementation and enforcement of smoke-free policies. Data were obtained from the 2009-2010 National Adult Tobacco Survey, a landline and cell phone survey of adults aged ≥18 years old residing in the 50U.S. states and the District of Columbia. The overall proportion of respondents who reported that smoking should "never be allowed" in workplaces, restaurants, and bars/casinos/clubs was calculated, both nationally and by state. National estimates were also calculated by sex, age, race/ethnicity, education, annual household income, sexual orientation, and smoking status. Nationally, 81.6% of U.S. adults think workplaces should be smoke-free (state range: 68.6% [Kentucky] to 89.1% [California]); 74.9% think restaurants should be smoke-free (state range: 59.5% [Missouri] to 84.6% [California]); 50.0% think bars/casinos/clubs should be smoke-free (state range: 32.3% [Nevada] to 61.3% [Maine]); and 47.5% think workplaces, restaurants, and bars/casinos/clubs should be smoke-free (state range: 30.3% [Nevada] to 58.8% [Maine]). Regardless of venue type, women, older individuals, non-Hispanic Asians, individuals with higher education and income, and nonsmokers were the most likely to think these environments should be smoke-free. A majority of U.S. adults think workplaces and restaurants should be smoke-free, while half think bars, casinos, and clubs should be smoke-free. Continued efforts are needed to educate the public about the dangers of secondhand smoke and the benefits of smoke-free indoor environments.
