This second edition will build upon the success of the first, and reflect recent rapid advances in pollution sciences and sampling technologies, especially in automatic online sampling and monitoring. With 13 updated chapters and 8 new chapters, this new edition will include the descriptions and examples of direct-reading instruments; the addition of spectrophotometric methods for measuring gases; a description of principles and techniques for sampling biological aerosols and sub-micron particles; a description of the development of new sensor technology, and greater emphasis on calibration. It also includes end-of-chapter problems and a solutions manual.
