摘要
为了解肝脏促癌剂微囊藻毒素(MC)在肝癌高发区饮用水中的污染情况,于1992至1993年对江苏海门居民饮用水中藻类及其产生的MC进行了检测,经鉴定在海门沟河水中颤藻是目前已被证明能产生MC的最常见的藻属;在65个水样中有2份经高效液相和液相色谱/质谱分析确定含有MC。进一步于1994年7月在江苏海门采集不同饮用水源共989份,采用高敏感度酶联免疫方法测定MC含量。结果在沟塘水、河水、浅井水和深井水中MC的阳性率(>50pg/ml)分别为17.3%,31.9%,4.3%,0.0%;阳性样本中MC平均含量分别为101,160,68,0。在沟塘水和河水中MC的阳性率和阳性样本中的平均含量均显著大于浅井水和深井水,提示应对饮用水中MC与肝癌的关系作进一步研究。
