1,1,1—三氯乙烷具有与四氯化碳相比美的昆虫毒力,但对哺乳动物的毒性却相对很低,英国农业部对1,1,1—三氯乙烷作为薰蒸剂的各种毒性进行了研究,用气相色谱法分析了1,1,1—三氯乙烷薰蒸的各种粮食经贮藏和加工后的散失。讨论了影响粮食吸附该薰蒸剂的因素,以及随后贮藏过程中的残留情况,并测定了薰蒸的小麦经加工制作面包的各个工艺过程引起的药剂散失,结果表明在面包中的残留量小于。.lmg/kg。将吸附和残留数据与早期用四氯化碳薰蒸的结果相比较,表明两种粮食薰蒸剂的
1,1,1-trichloroethane has the beauty of insect carbon tetrachloride toxicity, but the toxicity of mammals is relatively low, the British Ministry of Agriculture 1,1,1-trichloroethane as a smoked The various toxicities of steams were studied, and the loss of stored and processed 1,1,1-trichloroethane-fuminated grains was analyzed by gas chromatography. The factors that affect grain sorption of the fumigant and the ensuing residue during storage are also discussed. The loss of agent due to the individual processing of the fumigated wheat bread is measured and the results show that the amount of residue remaining in the bread is less than . .lmg / kg. Comparing the adsorption and residual data with the results of the earlier carbon tetrachloride fumigation showed that the two food fumigants
