Monitoring Toxic Gases in the Atmosphere for Hygiene and Pollution Control presents the principles of atmospheric monitoring, indicates where difficulties can occur, and where errors in sampling and measurement may be expected. Organized into ten chapters, this book first describes the measurement of toxic hazards and the corresponding techniques for measurement. Subsequent chapter discusses the sources of error in sampling and measurement. Other chapters focus on detection systems based on color change; total sample collection methods; selective sample collection methods; sampling pumps; and preparation of standards for calibration of instruments and evaluation of methods. The statistics of monitoring is also explained.
