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 mug 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 microg MC-LR equiv./l to more than 8.0 microg/l in raw water and were distinctly below 1.0 microg/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.
产生毒素的蓝藻细菌（蓝绿藻）在用作饮用水源的地表水中大量存在。这类毒素中的一组——微囊藻毒素的毒性以及它们在用于饮用水生产的地表水中的存在，促使世界卫生组织（WHO）发布了饮用水中微囊藻毒素（MC）-LR的临时指导值为1.0微克/升。为了验证两种不同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水样中的MC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微克MC-LR当量/升（原水中超过8.0微克/升）到处理后明显低于1.0微克/升。此外，还总结了世界各地自来水厂原水和成品水中蓝藻细菌的出现情况以及全球范围内饮用水中蓝藻毒素的相应指导方针。
