Many organophosphate pesticides (OPs) such as dimethoate are used to eradicate household pests, and those occurring in agriculture and forestry sectors. Combinations of two or more different insecticides have been manufactured to increase their effectiveness. A case of death is presented as suspected organophosphates intoxication. Autopsy was unremarkable except for grayish fluid in the stomach, with garlicky odor. A systematic toxicological analysis on post-mortem specimens revealed high concentrations of dimethoate in blood 38 microg/mL, urine 0.47 microg/mL, brain 2.2 microg/g, myocardial muscle 7.6 microg/g, liver 4.6 microg/g, lung 7.6 microg/g, skeletal muscle 21 microg/g, kidney 55 microg/g and gall bladder 31 microg/g. Blood alcohol was 2.85 g/L, cyclohexanone and cyclohexanol were also detected in the blood but not quantified. The cause of death was determined as organophosphate intoxication. 相似文献

An analytical method for the rapid screening of organophosphate pesticides in human biological samples and foodstuffs 总被引:2,自引:0,他引:2
Gas chromatography with nitrogen/phosphorus sensitive detection (GC/PND) and electron impact mass spectrometry (GC/MS) with selected ion monitoring provides a simple, rapid and sensitive method for the determination of organophosphate pesticides (OPs). A selective single-step extraction of 23 different OPs in urine, blood, serum and food samples (baby food, soft drinks and instant soups suspected of contamination from a blackmailing scare) is described. The OPs were extracted with 1ml toluene (with and without addition of mevinphos as internal standard), using a 0.7ml aliquot of urine, blood or serum sample. Food samples (0.2g) were homogenised with water (0.5ml) before extraction. An amount of 1microl of the toluene phase (extraction supernatant) was analysed directly by GC/PND and GC/MS.The method was validated using spiked human serum. The OPs were mixed with serum containing 10mg/ml disodium ethane diamine tetraacetic acid disodium salt (EDTA disodium salt) and stored up to 10 days at 4 and -20 degrees C, respectively. The recovery rates of OPs in freshly spiked human plasma ranged between 50% (dimethoate) and 133% (dialifos). OPs in plasma proved to be stable at -20 degrees C. Their levels decreased only slightly after storage at 4 degrees C. 相似文献

法官与律师关系规范化刍议 总被引:2,自引:0,他引:2
目前正在全国展开的律师队伍整顿工作将规范律师与法官的关系作为一项重点工作,拟通过教育、监督、惩治律师来彻底规范法官与律师关系的观点已得到普遍的认可。将规范律师执业行为作为切入点的做法,固然能对建立正当的法官律师关系起到一定的促进作用,但更为关键与根本的措施还在于严格规范法官依法行使审判权。围绕这一论点,论证了规范法官审判行为何以应当成为规范法官与律师关系的根本点;分析了少数法官在与律师职业交往中得以进行权力寻租的成因;并从平衡法官与律师的地位、增强律师对法官的监督与影响、阻却个别法官司法专横与防范司法腐败的角度,对规范法官与律师关系提出了一些建议。 相似文献
