Abstract

Recycling demands are increasing and new biowaste plants are established. The aim of this study is to obtain knowledge about occupational hygiene in biowaste pretreatment plants. At 6 plants, bioaerosol exposure, hand hygiene, and bioaerosol concentrations in work areas were investigated repeatedly. The total inflammatory potential (TIP) of exposures was measured using the human HL-60 cell line. Exposure to airborne bacteria, bacteria able to grow anaerobic, fungi(37°C), endotoxin, and TIP differed between plants and was lowest in a plant transporting waste in closed pipes compared to plants where waste was delivered on the receiving hall floor. Conversely, high exposures were measured in a plant that also processes compost. All microbial components had an impact on TIP of workers' exposure with main effects of fungi and endotoxin. Seasonality was found for several exposures and TIP, and they were lowest in the winter. Concentrations of bacteria and fungi on workers' hands at the end of the workday were 15 times higher for production than for nonproduction workers. In work areas, the concentrations of airborne fungi were highest in the waste-receiving area. Bacteria (3.2 µm) and anaerobic bacteria (4.0 µm) were present as larger airborne particles than fungi (2.8 µm), and bacteria were largest in the waste-receiving area. The microbial community compositions of exposures and work areas differed between plants and work areas. In conclusion, measures to reduce exposure should focus on the waste-receiving area and on the production workers. Differences in exposures and community compositions were found between seasons, work areas, work groups, and plants.

生物废料厂职业卫生横断面研究。

回收需求不断增加，新的生物垃圾处理厂也随之建立。本研究旨在了解生物垃圾预处理厂的职业卫生情况。对 6 家工厂的生物气溶胶暴露、手部卫生和工作区的生物气溶胶浓度进行了反复调查。使用人类 HL-60 细胞系测量了暴露的总炎症潜能（TIP）。不同工厂暴露于空气中的细菌、能厌氧生长的细菌、真菌（37°C）、内毒素和 TIP 的情况各不相同，与在接收大厅地板上运送废物的工厂相比，在封闭管道中运送废物的工厂暴露量最低。相反，在一家同时处理堆肥的工厂中测得的暴露量较高。所有微生物成分都会对工人的接触量产生影响，其中主要是真菌和内毒素。几种暴露和 TIP 都有季节性，冬季最低。工作日结束时，生产工人手上的细菌和真菌浓度是非生产工人的 15 倍。在工作区，废物接收区的空气传播真菌浓度最高。与真菌（2.8 微米）相比，细菌（3.2 微米）和厌氧细菌（4.0 微米）在空气中的颗粒更大，而细菌在废物接收区的数量最多。不同工厂和工作区的暴露和工作区的微生物群落组成各不相同。总之，减少接触的措施应侧重于废物接收区和生产工人。不同季节、不同工作区、不同工作小组和不同工厂之间的接触和群落组成存在差异。

期刊介绍： About the Journal Annals of Work Exposures and Health is dedicated to presenting advances in exposure science supporting the recognition, quantification, and control of exposures at work, and epidemiological studies on their effects on human health and well-being. A key question we apply to submission is, "Is this paper going to help readers better understand, quantify, and control conditions at work that adversely or positively affect health and well-being?" We are interested in high quality scientific research addressing: the quantification of work exposures, including chemical, biological, physical, biomechanical, and psychosocial, and the elements of work organization giving rise to such exposures; the relationship between these exposures and the acute and chronic health consequences for those exposed and their families and communities; populations at special risk of work-related exposures including women, under-represented minorities, immigrants, and other vulnerable groups such as temporary, contingent and informal sector workers; the effectiveness of interventions addressing exposure and risk including production technologies, work process engineering, and personal protective systems; policies and management approaches to reduce risk and improve health and well-being among workers, their families or communities; methodologies and mechanisms that underlie the quantification and/or control of exposure and risk. There is heavy pressure on space in the journal, and the above interests mean that we do not usually publish papers that simply report local conditions without generalizable results. We are also unlikely to publish reports on human health and well-being without information on the work exposure characteristics giving rise to the effects. We particularly welcome contributions from scientists based in, or addressing conditions in, developing economies that fall within the above scope.
