The quantitative analysis of 25 % chlorpyrifos and triazophos ec by reverse phase hplc was introduced , using acetonitrile and water ( 74 : 26 ) as mobile phase , using c18 column and ultraviolt detector 摘要本文叙述了采用反相高效液相色谱法即以乙腈+水为流动相， c18柱和紫外检测器同柱分离侧定25 %毒?唑乳油中的毒死蜱和三唑磷。
Dursban , a widely used organophosphorus pesticide nowadays in china , was choosed as the subject investigated . with the biosensor as mentioned before , the calibration curve , which has a quantitative determination range from 1 . 64 to 20 . 52ppm , was plotted 本文还选择了一种目前正在中国广泛使用的有机磷农药? ?毒死蜱作为对象，采用此酶电极传感器进行检测，绘制了将该传感器应用于毒死蜱检测时的标准曲线。
In this paper two - generation reproduction toxicity of fenvalerate , a - cypermethrin , chlorpyrifos , and triazophos was tested in a 21d period with water flea , daphnia magna , . the toxicity indicator included longevity , body length , days to first brood , days to first pregnancy , number of youth per female , intrinsic rate of natural increase ( r ) , and number of broods per female . accordingly , the dose - response relations and relations between the chronic responses and enzyme levels were investigated 为了确定水蚤体内生化指标与慢性毒害效应之间的关系，特别是在低浓度暴露状态下生化指标改变的生物学意义，以便能更准确预测早期农药对水蚤种群的潜在危害，本文以浙江省常用杀虫剂氰戊菊酯、高效氯氰菊酯、三唑磷和毒死蜱进行了大型蚤( d . magna )的急性和慢性毒性试验(包括子代水蚤的恢复试验) 。
At last , the quantitive detection for cucumber and greengrocery added certain enhanced insecticides including methamidophos , dimenthoate , acetphate , carbaryl and malathion was performed , and the results showed that the establishment of the quantitive standard could be helpful to estimate the insecticides residue in the samples 并在此基础上，选用了甲胺磷、氧化乐果、乙酰甲胺磷、毒死蜱、西维因和灭多威作为强化农药，对添加了一定强化农药量的黄瓜、青菜进行了定量测定，发现通过标准的建立，可以较真实地反映样品中的农药残留量。
Children who were exposed prenatally to the insecticide chlorpyrifos had significantly poorer mental and motor deelopment by three years of age and increased risk for behaior problems , according to a peer - reiewed study published today by the american academy of pediatrics in its journal , pediatrics 根据美国儿科研究院今天发表在其杂志上的一项回顾性学前教育的儿科检查研究，那些出生前曾暴露于杀虫剂毒死蜱的儿童在三岁的时候智力和运动发育明显不足，出现行为问题的风险也明显增加。
