在本文介绍的两项饮用水厂中试研究中，水源水采用了各种消毒方案，包括臭氧、一氯胺、二氧化氯和氯。通过XAD树脂吸附/乙酸乙酯洗脱制备水样中存在的有机化合物浓度。然后在艾姆斯沙门氏菌试验中测试浓缩物的致突变性，以比较不同消毒方法后水样的相对致突变性。

In the two pilot-scale drinking water plant studies presented here, source waters were treated with a variety of disinfection schemes, incorporating ozone, monochloramine, chlorine dioxide and chlorine. Concentrations of the organic compounds present in the water samples were prepared by XAD resin adsorption/ethyl acetate elution. The concentrates were then tested for mutagenicity in the Ames Salmonella assay in order to compare the relative mutagenic potencies of the water samples following the different methods of disinfection.
