Exploration and Practice of Comprehensive Experiment on Environmental Pollution and Food Safety—Taking the"Migration and Utilization of Heavy Metals in Soil Matrix-Edible Mushroom-Human Body"as an Example
Taking"the migration and utilization of cadmium in soil matrix,edible mushroom and human body"as an example,the representative samples of edible mushroom and its rhizosphere soil were collected from different regions of Yunnan Province.Based on the theoretical content related to environmental pollution and food safety,the basic composition and heavy metal content of the samples were analyzed.The migration rule of cadmium in the mushroom,rhizosphere soil and human body system was explored to increase the design and research of experiments.And the teaching model with"preparation-experimental process-analysis and summary-expanding thinking"was adopted,the teaching process with"basic-advanced-high order"was carried out.The difficulty coefficient of experiment was increased,and comprehensive experiment with academic characteristics was formed.The formation of comprehensive experiment was beneficial to consolidate students'understanding of interdisciplinary integration of knowledge of environment and food disciplines,improve students'practical operation ability and innovation ability,and cultivate high-quality talents with social responsibility.
