１９９４～１９９６年期间，对河南省三个水库、三条河流及三个以黄河水为水源的大型蓄水湖泊（池）进行了４２份次水样的藻类毒素检测。结果显示：总体阳性率为２３．８％，超标率为２．３８％。文章讨论了藻类毒素在地面水体中存在的普遍性及对健康的危害性。并建议主管部门应及早制订藻类毒素的卫生标准，以利开展卫生监督，保护人民身体健康。
During 1994-1996, 42 sub-samples of algal toxins were tested for three reservoirs in Henan Province, three rivers and three large reservoirs (pools) with Yellow River water as their source. The results showed that: the overall positive rate was 23.8%, exceeding the standard rate of 2.38%. The article discusses the prevalence and health hazard of algal toxins in surface water. It is also suggested that authorities should establish hygienic toxin standards as soon as possible to facilitate health surveillance and protect people’s health.
