Pesticides are usually chemical substances, though they can sometimes be biological agents, such as viruses or bacteria. They may be used as fungicides, herbicides or insecticides. This book focuses on the current analytical methodologies used to determine the levels and contents of pesticide residues in foods and in the environment. It includes information on: the pesticides that are used; sample preparation methods; quality assurance; chromatographic techniques; immnoassays; pesticide determination in food, soil, water and air; and the results of monitoring in food and the environment. |
