Objective: The epidemiological characteristics and trend of occupational pneumoconiosis in Hubei Province from 2011 to 2020 were analyzed to provide a theoretical basis for the development of prevention and control strategies for occupational pneumoconiosis. Methods: In March 2021, the data of newly occupational pneumoconiosis in Hubei Province from 2011 to 2020 were collected by the Occupational Diseases and Health Risk Factors Information Surveillance System. Descriptive statistics were adopted to analyze basic situation, region, industry, type of disease, year of diagnosis, age of onset and dust exposureduration of the cases. Results: From 2011 to 2020, a total of 7203 new cases of occupational pneumoconiosis were reported in Hubei Province, including 7125 (98.92%) men and 78 (1.08%) women. The average age of onset was (54.03±10.12) years old. The average duration of dust exposure was (13.80±9.56) years. The mainly types of pneumoconiosis were coal worker's pneumoconiosis (3593 cases, 49.88%) and silicosis (3301 cases, 45.83%). The cases included 4814 cases (66.83%) of stage Ⅰ pneumoconiosis, 1270 cases (17.63%) of stage Ⅱ and 1119 cases (15.54%) of stage Ⅲ. New cases mainly distributed in Yichang City (1586 cases, 22.02%), Shiyan City (1257 cases, 17.45%), Enshi Tujia and Miao Autonomous Prefecture (1050 cases, 14.58%) and Huangshi City (1009 cases, 14.01%), and occurred most frequently in coal mining and washing industry (3743 cases, 51.96%) and nonmetallic mining industry (582 cases, 8.08%). Pneumoconiosis patients of stage Ⅲ were mainly distributed in small enterprises (401 cases, 50.25%) and domestic enterprises (796 cases, 99.75%) . Conclusion: Coal worker's pneumoconiosis and silicosis accounted for the vast majority pneumoconiosis in Hubei Province. The new cases show obvious regions, industries and type of disease distribution. We should strengthen occupational health supervision in small and domestic enterprises.

Personal Hygiene of Workers in Waste Disposal Site Ponorogo Regency, East Java, Indonesia

Personal hygiene is useful in maintaining the health of workers. However, Personal Hygiene is considered less important for workers due to the knowledge and attitudes of workers' personal hygiene. One's knowledge will have a positive and negative impact on one's actions. Garbage becomes a source of various diseases if not managed properly. The purpose of this study was to analyze the personal hygiene behavior of waste disposal workers and the factors that influence behavior. The research method is qualitative with a descriptive approach, with a total of 10 informants. Data collection techniques were carried out by in-depth interviews and direct observation. The results of the research on the personal hygiene behavior of workers are very important, knowledge of workers regarding personal hygiene and occupational safety and health is very necessary, by paying more attention to and improving personal hygiene, by maintaining hand hygiene, feet, nails, hair hygiene and maintaining skin hygiene on a regular basis. completing sanitation facilities, increasing management support in the form of occupational safety and health supervision. Managers are expected to be able to apply Occupational Health and Safety and apply personal hygiene behavior in particular.

Discussion on the evaluation of occupational disease diagnostic criteria

Occupational disease diagnosis standards are an important basis for occupational disease diagnosis, occupational health surveillance, occupational health supervision, occupational disease treatment, occupational disease disability assessment, and handling of occupational disease diagnosis disputes in conjunction with the "Occupational Disease Prevention and Control Law of the People's Republic of China". With the successive promulgation of the "Standardization Law of the People's Republic of China" and the "Administrative Measures on Health Standards", the establishment of a mandatory standard implementation evaluation mechanism has gradually been paid attention to. However, there is still a lack of systematic research on the evaluation of diagnostic criteria for occupational diseases. Therefore, this article combines the current status of the diagnostic standards for occupational diseases in China, and proposes reasonable suggestions on how to carry out the evaluation of the implementation of this type of standard in terms of evaluation methods and content.

Investigation on the effect of occupational lead exposure on bone mineral density of workers

Objective: To understand the occupational health status of a lead-acid battery enterprise in Jiangsu Province, to observe the results of blood lead and bone mineral density (BMD) of the workers exposed to occupational lead, and to explore the effect of occupational lead exposure on BMD, so as to provide basis for the prevention and treatment of occupational lead poisoning and osteoporosis. Methods: An occupational health survey was conducted in a lead-acid battery enterprise in Jiangsu Province in January 2019. Basic information and occupational health examination results of 402 persons exposed to occupational lead were collected, and BMD was measured. Spearman rank correlation test was used to analyze the relationship between blood lead and BMD, and logistic regression analysis was used to analyze the influencing factors of BMD. Results: The blood lead level M (P25, P75) of 402 occupational lead exposure workers was 220.5 (118.0, 307.0) μg/L, 46 workers (11.4%) had blood lead value ≥400 μg/L, and 5 workers (1.2%) ≥600 μg/L. 124 workers (30.8%) had abnormal BMD. The concentrations of lead dust and lead smoke in the workplace were <0.004-0.027 and <0.021-0.045 mg/m3, respectively. The positions exceeding the standard point were mainly concentrated in the casting and welding group (44.4%, 4/9) of lead smoke positions. There was a statistically significant difference in the overall distribution of blood lead levels among lead exposure workers with different BMD levels, and there was a positive correlation between blood lead and BMD (P<0.01) . The results of univariate analysis showed that there were statistically significant differences in the distribution of abnormal BMD among workers exposed to different genders, positions and blood lead levels (P<0.01) . The results of multivariate logistic regression analysis showed that the risk of abnormal BMD in male workers was 5.069 times of that in female worker (95%CI: 2.906-8.840, P<0.01) . Conclusion: Occupational lead exposure personnel have a high blood lead level and a high abnormal BMD rate. Exposure to lead working environment is an influencing factor for the abnormal BMD of workers, so enterprise managers should pay attention to health protection, occupational health monitoring and supervision of working environment of front-line workers.

Objective: To explore the health status of occupational benzene exposure workers, and to provide a scientific basis for the development of reasonable health monitoring and effective protective measures. Methods: In March 2019, the occupational health surveillance data were collected including blood pressure, electrocardiogram, blood routine, urine routine, liver function, etc of 7810 benzene contact workers in 150 enterprises in Jiangxi Province in 2017, to analyze and assess their health status. Results: Among the 7810 benzene workers, there were 5451 males and 2359 females; the average age was (40.5±9.9) years; and the median benzene working age was 3.5 years. The detection rate of hypertension was 17.0% (734/4317) , the abnormal rate of urine routine was 15.7% (1227/7810) , the abnormal rate of liver function was 8.6% (356/4147) , and the abnormal rate of electrocardiogram was 12.3%(963/7810). The detection rates of low count number of leukocytes, platelets, neutrophils and occupational contraindications were 4.6%(360/7810) , 1.4%(108/7810) , 4.2%(330/7810) and 1.4%(110/7810) , respectively. The detection rates of low count number of leukocytes, platelets and neutrophils in female were all higher than those in male (P<0.05). The detection rates of low count number of platelets, neutropenia and occupational contraindications increased with age and working age (P<0.05 ). There were significant differences in the detection rates of low count number of leukocytes, platelets, neutrophils and occupational contraindications among benzene workers in different economic types (P<0.05) , and the highest among foreign companies, followed by private enterprise. There were statistically significant differences in the detection rates of low count number of platelets, neutrophils and occupational contraindications in benzene workers of different enterprise sizes (P<0.05) , and the highest was found in micro enterprises, followed by small enterprises. Conclusion: In 2017, the occupational health status of workers exposed to benzene in Jiangxi province is not optimistic. It is necessary to strengthen the occupational health supervision of small and micro-sized enterprises, foreign enterprises and private enterprises, take the initiative to improve health surveillance, and effectively protect the physical and mental health of workers.

Epidemiological study of occupational diseases in Gansu province, China in 2010-2017

Objective: To analyze the epidemiological characteristics of occupational diseases in Gansu Province, China in 2010-2017, and to provide a scientific basis for the prevention and control of occupational diseases. Methods: The cluster sampling method was adopted to make statistical analysis of 1339 cases of occupational disease reported by "occupational disease and occupational health information monitoring system" in Gansu province from 2010 to 2017, to investigate the diseases, regions and industries of occupational diseases in June 2018. Results: A total of 1339 cases of occupational diseases (39 types, 8 classes) were diagnosed and reposed in 2010-2017. The three most frequent diseases were pneumoconiosis (87.53%, 1172/1339), occupational poisonings (5.83%, 78/1339), and occupational ear, nose, and throat (ENT) diseases (3.14%, 42/1339). The cases of silicosis accounted for 54.61% (640/1172) of all cases of pneumoconiosis, the second was coalworker pneumoconiosis, which accounted for 38.57% (452/1172). In the cases of occupational poisonings, 32.05% (25/78) suffered from carbon monoxide poisoning. Patients with occupational diseases were reported in 14 districts of Gansu, mostly in Lanzhou (27.52%, 347/1261), Jinchang (16.57%, 209/1261), and Baiyin (14.20%, 179/1261). The reported cases are mainly concentrated in mining (71.56%, 468/654) and manufacturing (21.87%, 143/654), the types of state-owned economy (55.63%, 692/1244) and private economy (33.68%, 419/1244), large (43.41%, 540/1244) and small enterprises (35.21%, 438/1244) in 2010-2017 in Gansu. Conclusion: The pneumoconiosis caused by silicious and coal dust and the occupational poisonings caused by carbon monoxide seem to be the main occupational hazards in Gansu province. Occupational diseases occur in all districts of Guangzhou and in various industries. The state-owned economy and private sector, large and small enterprises should be the focuses of occupational health supervision.

An analysis of assessment results of prevention and control of occupational hazards in a city

Objective: To investigate the current status of prevention and control of occupational hazards in a city in 2017, to understand the capability to prevent and control occupational hazards and the level of occupational health supervision and management, and to propose measures to urge employers to assume the main responsibility for the prevention and control of occupational diseases. Methods: An analysis of the main factors influencing the prevention and control of occupational hazards in the city was performed to screen out six semi-quantitative assessment indicators (including the training of the main responsible persons and occupational health management personnel in companies) and four qualitative assessment indicators (including the coverage of supervision and inspection of occupational hazards performed by the district safety supervision department) , which could be used to measure the prevention and control effects of regional occupational hazards. Each indicator was scored. The typical investigation method was used to do data review and on-site inspection of 170 companies, 17 district-level occupational health supervision departments, and 16 sub-district (township) occupational health supervision departments in the city from October to December, 2017. The prevention and control of occupational diseases in each district was scored, and the completion rate and completion situation of each indicator in the city were analyzed. Results: The mean score of prevention and control of occupational hazards in the city was 84.9. The scores of two districts were relatively high, being 88.9 and 88.7, respectively; the scores of 9 (52.9%) districts were higher than 85. The pass rate of training for the main responsible persons and occupational health management personnel in companies in the city was 95.9%, the pass rate of occupational health training for workers was 84.7%, the pass rate of occupational health examination for workers was 96.5%, the pass rate for the inspection of occupational hazardous factors in workplaces was 95.3%, the pass rate for notifying occupational hazards in workplaces is 95.9%, and the pass rate for applying the warning signs of occupational hazards in workplaces was 76.5%. Conclusion: The awareness of the importance of prevention and control of occupational hazards in all districts of the city has been increased, but the effectiveness of occupational health training for workers needs to be strengthened. The supply and demand of occupational health technical services are still not matched, and the ways and methods of occupational health supervision and inspection need to be improved.

Research on the Occupational Noise Exposure Health Risk Management Standard

To prevent and control the occupational noise hazard, procedures and methods of risk assessment and management of occupational noise hazard in the workplaces have been proposed as technical guidelines in the new standard “Risk Management Guidelines for Noise Occupational Disease Hazard” based on the current status and technical requirements of occupational noise hazard in China. These guidelines are consist of the risk assessment method which partly adopts the method given by the latest ISO 1999:2013(E) “Acoustics — Estimation of noise induced hearing loss”, and the risk management procedures which are mainly based on the US NIOSH’s recommended standard “Occupational Noise Exposure Revised Criteria 1998”. The guidelines put forward procedures and technical contents such as the risk management program, occupational noise exposure quantitative risk evaluation procedures and methods, and the implementation details of a hearing conservation plan. The standard is based on the current status and technical requirements of the occupational noise hazard in China, in accordance with the relevant national laws, regulations and standards related to hearing protection and supervision and management of the occupational hazard of construction projects. It can be used as guidelines for occupational noise exposure evaluation and risk assessment in various kinds of workplaces that produce productive noises and for exposure level monitoring, effectiveness evaluation of noise control measures, occupational health management, supervision and inspection.

An analysis of occupational hazard in manufacturing industry in Guangzhou, China, in 2013

To provide data for the occupational health supervision by analyzing the occupational health status in manufacturing industry in Guangzhou, China. The occupational health investigation was performed in 280 enterprises randomly selected from 8 industries based on industry stratification. According to the occupational health standards, 198 out of the 280 enterprises were supervised and monitored. Sample testing was performed in 3~5 workplaces where workers were exposed to the highest concentration/intensity of occupational hazard for the longest time. Comparative analyses of the overproof rates of hazard were performed among enterprises, workplaces, and testing items from different industries. The concentrations of occupational hazard in 42.93% (85/198) of enterprises and 22.96% (200/871) of workplaces were above the limit concentration. The most severe hazards were the noises in shipbuilding and wooden furniture industries and the welding fumes in shipbuilding industry. Less than 30% of enterprises were able to provide occupational health examination and periodic test reports of occupational hazard in workplaces. The rate of the workers with abnormal occupational health examination results and the need for reexamination reached 6.63% (832/12 549), and they were mostly from shipbuilding, wooden furniture, and chemical industries. The occupational health supervision should be strengthened in enterprises, and hazard from noises and dusts should be selectively controlled or reduced. The publication of relevant data and information of occupational health in enterprises should be promoted to enhance social supervision.
