摘　　要：探讨了法医毒物实验室废有机溶剂的产生途径及收集、处理和利用。产生的途径主要有样品处理、样品配制、玻璃仪器清洗等。废溶剂一般要分类收集、混合溶剂单独收集。除了环保部门集中处理以外,实验室可以用萃取、蒸馏、旋转蒸发等方法处理。蒸馏出来的溶剂经气质联用评价后可用于玻璃仪器清洗、样品配制和样品萃取等目的。法医毒物实验室对有机溶剂的回收利用,可以保护实验人员,降低环境污染,减少实验室运行成本。The production, collection, processing and application of used organic solvents in laboratories of forensic drug analysis were discussed in this paper. The used solvents were produced in sample pretreatment, sample preparation, and washing of glassware, etc. The used organic solvents were preferably collected according to categories, and mixed solvents were collected separately. Except for batch processing by agencies of environment protection, the used organic solvents can be cleared by extraction, distillation or vacuum distillation in laboratories. The distilled solvents can be utilized for washing of glassware, sample preparation and extraction, and for other purposes, after evaluation by gas chromatography-mass spectrometry. Solvent recycling in laboratories of forensic drug analysis can protect analysts, lower environmental pollution, and decrease the cost in laboratories.
