同安水环境藻类及藻类毒素分布调查

厦门市同安区是肝癌高发区，１９８７－１９８９年肝癌标化死亡率为４０－４５／１０万，为弄清同安居民饮用水灌类毒素污染与肝癌高发关系，１９９８年８月对同安饮用水及水源环境样本藻类及微囊灌毒素污染进行了调查。采用ＥＬＩＳＡ法检测微囊藻毒素，显微镜镜检进行藻类计数，分类。

Study of Distribution of Algal toxin and Algal Species in Tong-an Environment

To study the special relationship between blue-green algae toxin contamination drinking water and primary hepatocellar carcinoma(Hcc)in Tong An district of Amoi.63 different types of drinking water sample were collected in august 1998.Application of ELISA method to detect the microcystins concentration.Counting and category by microscope.The results showed that shallow well water existed microcystins (MC) contamination in Tong An distract.The MC positive rate was 77.5%.The highest concentration of MC was 695.5ng/L.The median concentration of MC was 121.2ng/L.It is higher than other areas in our country.The dominant specie of blue-green algae in Tong An environment is oscillator which has been confirmed to product the microcystins.Comparing to the MC of drinking water samples in high and low HCC mortality villages.The MC contents were significantly higher in village of high HCC mortality than that of low mortality.
