| Abstract |
|
We describe an environmental instrumental analysis course that combines classroom lectures illustrating important techniques and chemical principles with laboratory exercises allowing students to examine lead contamination in residential homes. The sampling and analytical determinations undertaken in this course are designed to determine the lead content of exterior paint, soil, and drinking water in older homes to examine the sources and extent of Pb contamination in suburban residential areas. Students are involved in the formulation of hypotheses, design of sampling strategies, collection of field samples, laboratory analysis of collected field samples, and the preparation of written and oral reports. Results of the analyses performed by students show that Pb contamination still persists despite the ban on lead in paint and gasoline enacted more than 20 years ago. In addition to learning fundamental principles of instrumental analysis, students gain a better understanding of the challenges of conducting and evaluating environmental analytical measurements.
