| 摘 要： | 目的了解某市生活饮用水系统微囊藻毒素（MC）污染情况,探讨当地温度、光照时数、降雨量等气候因素与微囊藻毒素-LR（MC-LR）含量相关性。方法 2008~2010年每年3月和9月,采集水源水、出厂水、管网水水样,采用高效液相色谱法检测水中MC-LR的含量;采用SPSS 18.0统计软件对数据进行统计学分析。结果 2008~2010年共检测了248份水样,有12份水样检出MC-LR,总检出率为4.8%,最高含量为0.115μg/L。3月和9月的水样中MC-LR检出率存在极显著性差异（P〈0.01）,水源水、出厂水和管网水水样中MC-LR检出率无显著性差异（P〉0.05）。MC-LR含量与温度、光照时数间存在较强的线性相关关系（P〈0.01）,与降雨量间无相关关系（P〉0.05）。结论某市生活饮用水系统受到以MC-LR为代表的微囊藻毒素的污染,但其值低于国家标准《生活饮用水卫生标准》（GB5749-2006）规定的限值0.001mg/L。温度、光照时数对MC-LR含量有重要影响。

| Abstract: | Objective To survey the pollution level of microcystin-LR in drinking water systems in Zhuhai City and analyze the correlation of the local temperature,light hours,rainfall with microcystin-LR(MC-LR)concentration.Methods Water samples were collected from source water,finished water,tap water in 2008~2010 in March and September each year.Concentration of MC-LR was detemined by high performance liquid chromatography.Results 248 water samples were tested,MC-LR was detected in 12 water samples,the total detecti... |
