1) water quality goal
2) effluent water quality
3) tap water
Tests are conducted on the mutagenicity and acute toxicity of raw water sample,tap water sample,and filtered water sample from two sources by means of Ames test and luminescent bacterium bioassay.
4) treated water
Moreover,we study on the water head and treated water fr.
The method of HPLC was applied to examine exactly the contents of trace intracellular and extracellular LR, YR, RR microcystin in source water and treated water, of which the samples were collected from August 1998 to June 1999 and concentrated by ODS silica gel column.
Increasement tendency of nitrite nitrogen in treated water of water treatment works was analysed.
5) Finished water
The solid extractive technique (amberlite GDX-120 resin) was used to extract respectively the organics from both raw water into and finished water from the five waterworks in the seasons of spring,summer and winter,and then the mutagenic activity of the organics was determined according to Ames assay.
采用固相萃取技术 (GDX -1 2 0大孔树脂 )于春、夏、冬季对以嘉陵江为水源的A厂和B厂、以长江为水源的C厂和D厂以及以两江汇水为水源的E厂提取进厂水与出厂水中的有机物 ,以Ames试验评估其致突变活性。
