城市污水处理厂微生物气溶胶暴露疾病负担研究
Study on the disease burden of exposure to microbial aerosols in municipal wastewater treatment plants
摘要
Abstract
Municipal wastewater treatment plant workers,who are exposed to the microbial aero-sol generated during the operation environment,can inhale pathogenic microorganisms through breathing,which ultimately causes loss of healthy life span.In response to this problem,this study quantitatively identifies aerosol particles and the pathogens they carry in the air of wastewater treatment plants.It also clarifies the occupational exposure risks faced by workers.By combining quantitative risk assessment of microorganisms with disease burden research meth-ods,the study employs the disability adjusted life year(DALY)as a key health evaluation index.A new model and calculation method system for microbial aerosol occupational health risk assess-ment based on DALY were proposed,and further selection of typical pathogens for disease bur-den calculation was conducted.The results show that during the occupational exposure process of typical wastewater treatment plant workers,the health losses caused by inhaling norovirus,ade-novirus,and rotavirus through aerosols are significantly higher compared with WHO standards,and process improvement or restriction of exposure is needed.关键词
