摘要
Abstract
Water from 10 indoor swimming pools with different sizes and types and tap water from 6 different areas in Beijing were investigated to analyze the occurrence of chlorinated disinfection byproducts (trichloromethane,chloroacetic acid and dichloroacetonitrile) in domestic indoor swimming pool water and tap water.Trichloromethane and chloroacetic acids formation potential of two types of precursors (natural organic matter and human body excretion) were compared at the same time.Results showed that average concentrations of trichloromethane,chloroacetic acid and dichloroacetonitrile in indoor swimming pool water were 29.2,79.4 μg/L and 1.31 μg/L,respectively,and in tap water were 23.7,4.6 μg/L and 0.22 μg/L,respectively.Under the same condition,human body excretion showed higher potential to form chloroacetic acid than to form trichloromethane,while natural organic matter exhibited the opposite formation potential.These findings confirmed the conclusions that disinfection by-products were different in indoor swimming pool water and tap water,where the main precursors were human body excretion and natural organic matter,respectively.关键词
