The objective of this manual is to provide a set of basic analytical procedures commonly used to determine environmental quality. Procedures are designed to be used in an introductory course in environmental science and are explicit enough to allow them to be performed by both the non-science or beginning science student. Stressing ecology and environmental science, the 30 exercises are based on quantitative and qualitative determinations, using material collected from the immediate locale. This can provide the student with an awareness of the pollution parameters within his own community, their sources, and possible solutions. The manual is divided into six parts: (1) Particulate Matter and Chemical Parameters Affecting Air Quality, (2) Chemical Analysis of Water, (3) Microbiological Examination of Water, (4) Physical Parameters of Water, (5) Identification of Pesticide Residues by Thin-Layer Chromatography, and (6) Appendixes--glossary, equivalents, effects charts, standards, publications. A discussion of the parameters is included at the beginning of the exercises and major sections pointing out the significance of the parameters to our environmental health. At the end of each exercise is a Result Table to be completed by the student. It supplies criteria supportive to the application of deductive and inductive reasoning to the questions that follow each experiment. (BL)
