The use of municipal wastewater treatment plants for the disposal of industrial wastes creates the potential for the exposure of treatment plant workers to hazardous chemical compounds that may be present in these wastes. Urine from workers and air and wastewater samples from a municipal wastewater treatment plant receiving wastes from a pesticide manufacturer were analyzed on several occasions by electron-capture gas chromatography for the presence of the compounds hexachlorocyclopentadiene (HEX) and hexachlorobicycloheptadiene (HEX-BCH) which are present in the waste stream from this industry. HEX-BCH was detected more frequently in urine from these workers than in urine from workers at another municipal wastewater treatment plant in the same city. Urine concentrations of HEX-BCH were found to be higher in specimens collected late in the work shift than in those collected earlier. The primary rate of exposure is thought to be by inhalation. This is the first known report of these compounds being detected in human urine and it demonstrates the potential for wastewater treatment plant worker exposure to industrial wastes.
利用城市污水处理厂来处置工业废弃物，会使处理厂工人有可能接触到这些废弃物中可能存在的有害化合物。对一家接收农药生产厂家废弃物的城市污水处理厂的工人尿液以及空气和废水样本，多次采用电子捕获气相色谱法分析其中是否存在六氯环戊二烯（HEX）和六氯双环庚二烯（HEX - BCH）这两种该行业废物流中存在的化合物。与同一城市另一家城市污水处理厂的工人尿液相比，这些工人尿液中HEX - BCH的检出频率更高。发现工作班次后期采集的尿液样本中HEX - BCH的浓度高于早期采集的样本。主要暴露途径被认为是吸入。这是首次有报告称在人类尿液中检测到这些化合物，它证明了污水处理厂工人接触工业废弃物的可能性。
