对两个荷兰原水水源地的样品在不同pH：S和氯剂量下进行了实验室氯化处理，并对其致突变活性和致突变化合物3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone(MX)进行了分析。氯化作用在两种水体中都产生了诱变活性和MX。酸性反应条件和高氯量有利于MX的形成，但在pH为9时过量氯处理的水中，未检测到MX。经氯化处理后，两种水的致突变性基本相同，但在以腐殖质为主的水中，MX的浓度明显较高。XAD树脂吸附技术可从酸化水中定量提取MX。
Samples from two Dutch raw water sources were chlorinated in the laboratory at different pH:s and chlorine doses, and were analysed for mutagenic activity and the mutagenic compound 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX). Chlorination produced mutagenic activity as well as MX in both waters. The formation of MX was favoured by acidic reaction conditions and high chlorine doses, but in waters treated with excess chlorine at pH 9, no MX was detected. The mutagenicity was approximately on the same level after chlorination of both water types but the MX concentration was significantly higher in the water containing mainly humic material.MX was found to be quantitatively extracted from acidified waters by the XAD resin adsorption technique.
