摘要
丙酮氰醇在工业上使用较广泛,常有急性中毒发生,为了制订该化合物车间空气卫生标准,我们对上海石化厂丙酮氰醇车间进行了职业流行病学调查,并选用该厂条件基本相同的醋酸车间工人作对照。共空测129个样本仅2个未检出,检出率为9844%,最高为聚合釜点,平均浓度为107mg/m3,范围006~1319mg/m3,最低为控制室外平均为0188mg/m3,范围为0~154mg/m3。本调查发现,丙酮氰醇车间工人神经衰弱症候群99人中检出48人,检出率为4849%,而醋酸车间工人97人中检出24人,检出率为2474%。两组比较差异非常显著(P<001),γGT检出率为61%,而对照组检出率为103%。差异显著(P<001)。血红蛋白为149±134g/L,对照组为133±1212g/L,差异非常显著(P<005)。结果提示丙酮氰醇虽是管道化生产,但在合成釜测定点逸出的丙酮氰醇较高。工人接触时间尽管很短,但对工人健康的慢性影响仍然存在。除防治急性中毒外,该化合物的慢性影响不能忽视。
In order to set the MAC of acetone cyanohydrin in air,an epidemiological study in the acetone cyanohydrin workshop of Shanghai petrochemical facory was carried on The workers of acetic acid workshop in the same factory were selected as the control group Among those 129 air samples in total,the highest concentration was located in polymer plant,averaging at 1 07mg/m 3,and ranging at 0 06~13 19mg/m 3 The lowest concentration was shown just outside the control room,averaging at 0 061mg/m 3 amd ranging at 0~1 54mg/m 3 Among the 99 workers in acetone cyanohydrin workshop,48 of them showed neurasthenic syndrome(48 49%),whereas among the 97 workers in acetic acid workshop,24 workers showed the same symptom(24 74%) Their difference was statistically significance( P <0 01) The other indices showed significance between those two groups including γ GT(6 1 vs 1 03%, P <0 01),Hb(14 9±13 4g/L vs 13 3±122 12g/L, P <0 05) The results suggested that the chronic effect of acetone cyanohydrin would not be ignored
