利用四段滤膜法进行干沉积监测

Dry deposition measurement by four-stage filter pack method

在酸雨研究领域,人们普遍是对降雨或降雪等湿沉积过程进行研究。近年来,干沉积也引起了大家的关注,但尚未建立成熟的方法。文章介绍了利用四段滤膜法进行干沉积监测的方法,作为日本全国公害研究协会的合作项目在日本神户和丰冈市进行了实际测量和评估。

Generally, the wet deposition is studied in the acid rain study field. Recently years, the dry deposition has been paid more attention, but the standard measurement method of dry deposition hasn't been established completely. The paper reports the dry deposition measurement by using the four-stage filter pack method for determining the atmosphere of gas (SO_2, HNO_3, HCl, NH_3)and aerosols matter (Cl, SO_4^(2-), NO_3^-, NH_4^+, Na^+, K^+, Mg^(2+), Ca^(2+)) concentrations.
