工业焚烧炉尾气中HCl含量的测定

用离子色谱法测定焚烧炉尾气中氯化氢含量的方法。由于焚烧炉排气尾气具有温度高的特点，该试验采用将６０ｃｍ左右的石英管一端插入焚烧炉排气烟筒中，另一端连接装有浓度为０．０１／ｍｏｌ．Ｌ－１ＮａＯＨ溶液的吸收瓶的采样方法。该方法采样简便，易操作，采完的样品可直接进入离子色谱仪中进行测定，其方法加标回收率９７％～１０５％，相对标准偏差小于３％。     

A case study of dioxin monitoring in and around an industrial waste incinerator in Korea

Many studies have been conducted that monitor and trace the sources of polychlorinated dibenzo-p-dioxin/furans (PCDD/Fs) by comparing congener patterns of environmental samples with those of possible sources. In this study, we measured PCDD/F concentrations and compared congener patterns of samples of various media found in and around an industrial waste incinerator in Korea, including stack gas, fly ash, bottom ash, ambient air, soil, pine needle, and human blood. We obtained reliable data on the relationship between the PCDD/F distributions in these sources and the environment, and thus found indicators with which to assess the impact of such sources on the surrounding environment. In addition, the difference between the levels of PCDD/Fs in the blood of short-term workers and long-term workers demonstrates that these workers are exposed to the compounds produced by the indicator.
