[영문] The management and disposal of harzardous chemicals from the middle school science class are studied for the saftey in science class and for the protection of the environment . Research was done by the analysis of 5 kinds of current middle school science text book and questionnaire survey, and review of the recommanded methods for the disposal of harzardous chemical wastes from science class. There are 237 chemicals appeared in the middle school science text books, among them 87 actually used in middle school science laboratory. 51 chemicals are classified as hazadous ones, and 49 are as highly hazardous by the "Law of Toxic Chemicals", 116 chemicals as water pollutants and 10 are highly hazardous water pollutants, by the "Water Quality Control Law", 91 chemicals as air pollutants and 19 are highly hazardous air pollutants by the "Air Quality Control Law". Questionnaire survey results on the identification of toxic chemicals, need for education, awareness of toxic effects and current problems in the management and disposal of toxic chemicals in middle school science class showed that most of middie school science teachers thought that the chemical wastes from the science laboratory might cause environmental pollution, they disposed them to the drain or waste bin without treatment. Most of science teacher wanted to have opportunities to attend supplement courses for the management and disposal of chemicals for the safety and environmental protection. Arrangement of simple and serviceble methods for the management and disposal of chemicals at middle school science level is strongly needed. Some treatment methods of hazardous chemicals serviceable for the middle school science class are presented.restrictio
