摘要
A one-year study was conducted on the chloroform concentrationof the municipal drinking water of Hyderabad City. Consumertap water samples were collected from different parts of thewater-distribution system of the city. Duplicate samplescollected from the sites were extracted with organic solvent,pentane and analysed using a gas chromatograph equipped with63Ni electron capture detector. Results indicate avariation in haloform concentration in different seasons ofthe year. A maximum concentration, ranging from 67.0–70.5μg/l was observed during the summer. However, the meanlevel of chloroform was below the permissible level of 30μg/l recommended by WHO (1984).
