Particulate matter are fine particles, and soot, which are tiny subdivisions of solid matter suspended in a gas or liquid. Sources of particulate matter can be man-made or natural. Air pollution and water pollution can take the form of solid particulate matter, or be dissolved. In this book, the authors gather and present topical research in the study of the sources, emission rates and health effects of particulate matter. Topics discussed include particles and aerosols in the indoor environment; airborne particulate pollution in a tropical urban environment; particulate matter originating from mining-metallurgical processes; non-respiratory health hazards of particulate matter; possible effects of ambient air pollution in male reproduction and satellite remote sensing of atmospheric particulate matter.
