摘    要:本文采用气-液双膜模型和大连湾水文参数,对大连湾检测出的挥发性有机物的挥发速率常数进行估算。结果表明,三氯乙烯等14种挥发性有机物在大连湾海域中的挥发速率常数在8.0×10^-3h-1-1.4×10^-2×^-1之间,挥发半衰期在50h=80h之间。因此,挥发至大气是这些在机物主要归宿。

关 键 词:大连湾  估算  挥发性  有机污染物  挥发速率常数

Abstract:The two film mass transfer model was used to estimate the volatilization coefficients and half life of the fourteen volatile organic chemicals(VOCs) detected in Dalian Bay.The results showed that the valitilization coefficients of the VOCs are between 0.008/h and 0.014/h,and the half life between 50 h and 80 h.Therefore,Transfer from seawater to atmosphere is the major chemical transfer process of the VOCs in thd bay.
Keywords:volatile organic chemicals  volatilization coefficient  Dalian Bay
