作为饮用水资源的地表水中富含产毒蓝藻（蓝绿藻）。其中一类毒素微囊藻毒素的毒性及其在用于饮用水生产的地表水中的存在促使世界卫生组织（世卫组织）公布了微囊藻毒素(MC)-LR/l饮用水的临时指导值1.0 μ g。为了验证两种不同的水处理系统在减少蓝藻毒素方面的效率，对瑞士和德国地表水及其相关水处理厂的水样中MC的浓度进行了调查。饮用水处理厂样品中的毒素浓度范围从低于1.0 μ g MC-LR当量/l到高于8.0 μ g/l，处理后明显低于1.0 μ g/l。此外，还总结了世界范围内自来水厂原水和最终水中蓝藻的发生情况以及相应的世界范围内饮用水中蓝藻毒素的指导方针。(c) 2004 Elsevier Inc.版权所有。
Toxin-producing cyanobacteria (blue-green algae) are abundant in surface waters used as drinking water resources. The toxicity of one group of these toxins, the microcystins, and their presence in surface waters used for drinking water production has prompted the World Health Organization (WHO) to publish a provisional guideline value of 1.0 mu g microcystin (MC)-LR/l drinking water. To verify the efficiency of two different water treatment systems with respect to reduction of cyanobacterial toxins, the concentrations of MC in water samples from surface waters and their associated water treatment plants in Switzerland and Germany were investigated. Toxin concentrations in samples from drinking water treatment plants ranged from below 1.0 mu g MC-LR equiv./l to more than 8.0 mu g/l in raw water and were distinctly below 1.0 mu g/l after treatment. In addition, data to the worldwide occurrence of cyanobacteria in raw and final water of water works and the corresponding guidelines for cyanobacterial toxins in drinking water worldwide are summarized.
