从对我县15家镀工厂91—92年连续两年的调查结果看,车间空气中铬浓度测定样品超标率不高6.67%、5.33%,平均浓度90年为0.0022mg/m~3,91年为0.0017mg/m~3,低于国家标准;而接铬工人铬鼻病患病率90年、91年分别达35.58%、38.64%,“单纯性铬性鼻炎”患病率90年,91年分别达18.40%,21.82%,鼻腔症状发生率90、91年分别达68.10%、60.00%,均较高。其原因为部分工厂领导
From the survey of 15 plating factories in our county for 91-92 for two consecutive years, the over-standard rate of chromium in the air of the workshop was not high 6.67% and 5.33%, and the average concentration was 0.0022mg / m ~ 3,91 Year was 0.0017mg / m ~ 3, lower than the national standard; and chromium workers chrome rhinopathy prevalence of 90 years, 91 years were 35.58%, 38.64%, “simple cholera rhinitis,” the prevalence of 90 years, 91. respectively, 18.40%, 21.82%, the incidence of nasal symptoms in 90, 91 years, respectively, 68.10%, 60.00%, were higher.
