| 摘 要： | 半透膜采样装置(SPMD)作为一种重要的被动采样器,被用于监测有机污染物的环境水平.SPMD的采样材料是置于低密度聚乙烯"口袋"中的三油酸甘油酯.根据有机污染物在被动采样材料与环境介质之间的平衡分配系数(包括被动采样材料/空气分配系数K(sA).和被动采样材料/水分配系数K(sw))值,可估算SPMD的采样速率,也可计...

| Abstract: | emi-permeable membrane devices(SPMD) are employed as a passive sampler to determine environmental levels of organic contaminants.The sampling material is triolein contained in the tube,made of low-density polyethylene.The equilibrium partition coefficients between the sampling material and the environmental media(SPMD/air partition coefficient KSA and SPMD/water partition coefficient KSW) are required to determine the sampling rates and estimate the concentrations of the pollutants.However,the deployment of... |
