中文摘要：

对高校化学实验室开设实验项目过程中产生的污染物“三废”（废水、废气、废渣）的原因、种类、数量、性质等进行调查统计。统计数据来源于甘肃省某高校的分析化学实验、无机化学实验、有机化学实验、仪器分析实验、环境分析和食品分析等6门实验课所开实验项目，最终分析了污染物产生的原因，提出治理方案，以期加强高校化学实验室的污染控制，推动化学实验室的教学改革，保护环境。

英文摘要：

Reasons, kinds, quantities and characteristics of ＂three wastes＂ of exhaust gas, wastewater, and waste residue from chemical laboratory in colleges were investigated. Statistical data were from six experimental course of a college in Gansu Province, such as analytical chemistry experiment, inorganic chemistry experiment, organic chemistry experiment, instrumental analysis experiment, environmental analysis and food analysis. The causes of pollutants were analyzed and governance program was proposed, which was to strengthen pollution control of chemistry lab to promote teaching reform of chemistry lab and to protect environment.
