The lead burden of occupational lead-exposed workers in Guangzhou, China: 2006-2019.
We analyzed the lead levels in blood and urine from lead-exposed workers in Guangzhou and assessed the influencing factors. The data were analyzed by descriptive statistics, and the time-dependent changes were mapped via analytical statistics. Although the lead burden showed a clear downward trend over time, it remained high among the exposed workers. The highest lead burden was detected in workers of the electrical equipment manufacturing industry, especially among those in lead-acid battery factories where we did field studies. Hazardous as the working conditions of the original lead-acid battery factories were, there were improvements in the applications of occupational disease prevention measures after the relocation of factories, but the lead burdens were still above the average levels of lead-related industries. Improvements are needed in the management and regulations on occupational safety and health to further decrease the lead burden to acceptable levels.
期刊介绍:
Archives of Environmental & Occupational Health , originally founded in 1919 as the Journal of Industrial Hygiene, and perhaps most well-known as the Archives of Environmental Health, reports, integrates, and consolidates the latest research, both nationally and internationally, from fields germane to environmental health, including epidemiology, toxicology, exposure assessment, modeling and biostatistics, risk science and biochemistry. Publishing new research based on the most rigorous methods and discussion to put this work in perspective for public health, public policy, and sustainability, the Archives addresses such topics of current concern as health significance of chemical exposure, toxic waste, new and old energy technologies, industrial processes, and the environmental causation of disease such as neurotoxicity, birth defects, cancer, and chronic degenerative diseases. For more than 90 years, this noted journal has provided objective documentation of the effects of environmental agents on human and, in some cases, animal populations and information of practical importance on which decisions are based.
