Fifty randomly selected workers in a sewage treatment plant using a heat treatment method for processing sewage sludge in Toronto, Canada were assessed. This investigation revealed that many workers reported "influenza-like" symptoms, cough, sputum production, wheezing, sore throat and skin complaints. The workers tended to have somewhat reduced lung function. Workers in the area of the plant where boiled sewage sludge was dried frequently reported an intermittent, acute illness characterized by cough, fever and sore throat. Workers in the area of the plant where the dried sludge was incinerated tended to have reduced lung function. The basis for the possible health effects demonstrated has not been established, and further investigation is suggested. The mean level of polychlorinated biphenyls (PCBs) detected in the workers' serum was 6 +/- 5 ppb. The PCB levels could not be related to symptoms or clinical findings in the workers studied.
对加拿大多伦多一家采用热处理方法处理污水污泥的污水处理厂随机抽取的50名工人进行了评估。这项调查显示，许多工人报告有“流感样”症状、咳嗽、咳痰、喘息、喉咙痛和皮肤问题。这些工人的肺功能往往有所下降。在工厂中经常晾晒经煮沸的污水污泥的区域工作的工人，经常报告有一种以咳嗽、发热和喉咙痛为特征的间歇性急性疾病。在工厂中焚烧干污泥区域工作的工人肺功能往往下降。已证明的可能健康影响的依据尚未确定，建议进一步调查。在工人血清中检测到的多氯联苯（PCBs）平均水平为6±5 ppb。多氯联苯水平与所研究工人的症状或临床发现无关。
