Advantages of green methodologies over traditional techniques to extract pesticides from the environment are also presented. Also included in the book is a review of the most important sources of Hg into the environment and an evaluation of the use of different animal species as bioindicators of human mercury exposure. A variety of regional air pollution issues including the toxicity of smoke and the harmful effects of high surface ozone concentrations effects on human''s health and crop production are examined.
