This study investigated the occurrence of hearing loss among workers of a petrochemical industry during a period of five years. The records of environmental noise and solvents measurements and the results of annual audiometry performed by the company were examined. The audiometric results of workers from olefin operational areas 1 and 2 and aromatic plant areas exposed to solvents and noise and utility area workers exposed only to noise were analyzed for the standard threshold shift (STS). Despite the low exposures to solvents and a moderate exposure to noise, 45.3% of workers had hearing losses and 29.6% had STS.
本研究调查了某石化行业工人在五年期间听力损失的发生情况。检查了环境噪声和溶剂测量记录以及该公司进行的年度听力测定结果。分析了烯烃作业区1和2以及接触溶剂和噪声的芳烃厂区工人以及仅接触噪声的公用事业区工人的听力测定结果，以确定标准听阈偏移（STS）。尽管溶剂接触量低且噪声接触量适中，但45.3%的工人有听力损失，29.6%的工人有STS。
