Abstract

A study was conducted to compare the efficiency of five adsorbents used by government and private laboratories to collect airborne pesticides. Six pesticides, acephate, chlordane, chlorpyrifos, diazinon, heptachlor, and propoxur, were vaporized in a closed system and collected on each of the adsorbents, Chromosorb 102, ORBO 42, ORBO 44 (chlordane and heptachlor only), polyurethane foam (PUF) or Tenax GC, by drawing 250 L of air through the adsorbent. There were no differences in collection efficiency of the five pesticides on Chromosorb 102, ORBO's 42/44, and PUF. The efficiency with Tenax was somewhat less with several of the pesticides.

摘要

开展了一项研究，以比较政府实验室和私人实验室用于收集空气中农药的五种吸附剂的效率。在一个封闭系统中蒸发六种农药，即乙酰甲胺磷、氯丹、毒死蜱、二嗪农、七氯和残杀威，通过吸附剂抽取250升空气，将这些农药收集在每种吸附剂上，这些吸附剂分别是Chromosorb 102、ORBO 42、ORBO 44（仅用于氯丹和七氯）、聚氨酯泡沫（PUF）或Tenax GC。五种农药在Chromosorb 102、ORBO 42/44和PUF上的收集效率没有差异。使用Tenax时，几种农药的效率略低。
