The gold standard of any scientific experiment or procedure is repeatability. Any peer should be able to produce similar results by working from the laboratory notes of the original investigator. The practice of environmental chemistry demands an even higher standard, that of "legal defensibility." Since any laboratory monitoring, no matter how routine, can easily end up as evidence in a pollution case, lab notebooks must not only show proper, repeatable scientific procedures, but also must do so in a standardized format subject to legal scrutiny.
Environmental Laboratory Exercises for Instrumental Analysis and Environmental Chemistry is a stand–alone, complete summary of laboratory work for environmental chemistry students. It presents a richly detailed set of classroom–tested experiments along with background information, safety and hazard notes, a list of chemicals and solutions needed, data collection sheets where necessary, and blank pages so students can compile results and summarize findings.
This useful resource also:
- Focuses on environmental, i.e., "dirty" samples
- Stresses critical concepts like analysis techniques and documentation
- Includes water, air, and sediment experiments
- Includes an interactive software package for pollutant fate and transport modeling exercises
- Functions as a student portfolio of documentation abilities for job or graduate school applications
- Offers instructors actual samples of student work for troubleshooting, notes on each procedure, and procedures for solutions preparation
In addition to its comprehensive presentation of laboratory and documentation exercises, this text emphasizes the essential skill of statistical analysis. A widely applicable spreadsheet exercise greatly increases student understanding of data analysis techniques and correct instrument calibration.
Environmental Laboratory Exercises for Instrumental Analysis and Environmental Chemistry provides the best and most exhaustive laboratory manual for advanced undergraduates or graduates studying instrumental analysis, environmental chemistry, or advanced analytical techniques.
