| 摘 要： | 目的探讨甲苯与听力损失的关系以及甲苯和职业性噪声对听力损失的影响。方法利用回顾性队列研究,选择广州市某冷轧厂连续性噪声作业人员224名男性接触甲苯者为甲苯组,在相同的噪声暴露环境中选择140名男性不接触甲苯者为对照组,对噪声暴露作业场所进行测点选择和噪声强度测量〔dB(A)〕,并计算累积噪声暴露量(CNE)。对工人进行左、右耳500-6000Hz6个频率的纯音气导听阈测试,并问卷调查。分析噪声和甲苯对听力的影响以及两者的联合作用。结果同一噪声暴露环境下,在4000Hz频段,甲苯组左、右耳听阈位移分别为(30.1±13.3dB(A),30.2±13.6dB(A))]6000Hz听阈位移为(27.0±12.9dB(A),28.4+16.4dB(A)]均高于对照组(P0.05)。甲苯组听力损失的发生率为20.5%,对照组为11.4%,两组比较差异有统计学意义(P0.05),年接触甲苯量50mg/m3以上听力损失发生的相对危险度是不接触甲苯的2.3倍(P0.05)。累积噪声量达80(dB(A))及以上时,甲苯与职业噪声联合作用的RR值(9.773)大于两个变量独立作用之和。结论大量接触甲苯可导致听力损失发生率增高,在高强度噪声暴露情况下,甲苯和职业噪声暴露对听力损失存在协同作用。

| Abstract: | Objective To observe the effect of expoure to toluene and occupational noise on hearing loss. Methods A historical cohort study was designed to study the toluene-and-noiseinduced hearing loss (NIHL)in 224 male workers exposed to toluene (toluene group)and 140 male workers exposed to noise in the same environment ( control group).The noise level was measured according to GBZ/T189.8-2007 and the cumulative noise exposure (CNE)was calculated. Hearing loss acuity was assessed by a qualified audiologist using th... |
