Pesticides in Fruits and Vegetables
This introductory module explores the structure/solubility relationships of organic compounds, explains how to extract pesticide residues from fruits and vegetables, analyzes the extract for pesticide content using gas chromatography, and uses the data collected as a basis for discussion about the issues surrounding pesticide regulation. Intended for use in the laboratory portion of an introductory environmental chemistry or general chemistry course.
