不同洗涤剂对高效氯氰菊酯的清除试验

Clearance Test for Different Detergents on Beta-cypermethrin

研究了洗洁精、洗衣粉和皂粉对高效氯氰菊酯的清除效果,用洗洁精洗手4次可将手上的稀释了1000倍的高效氯氰菊酯对家蚕的影响降至7.5%;用稀释10 000倍的高效氯氰菊酯药液喷施桑园,2天后采桑叶样,发现可致五龄起蚕100%死亡,但用稀释100倍的洗洁精处理桑叶样2次、用稀释500倍洗洁精处理桑叶样3次对家蚕是安全的;用稀释1000倍的洗洁精处理桑叶样3次,家蚕的死亡率降至15%。试验表明,相比皂粉和洗衣粉,洗洁精的适当处理能完全清除低浓度高效氯氰菊酯对桑叶和双手的污染。

The study compared the effects of different protein precipitation and drying methods on protein amino acid content/composition and nutritive value of protein powder from mulberry leaves.Results showed that protein amino acid content and composition of leaf proteins were different due to the use of different protein precipitation method rather than the protein drying method.The score of ratio coefficient(SRC)value of mulberry leaf protein was 69.29.The first limiting amino acid of mulberry leaf protein was methionine.The amino acid content of the leucine,isoleucine,lysine,threonine and valine all meet the standard of the FAO/WHO,the amino acid content of aspartic acid,proline and glutamic acid.
