Caption: Pesticide pollution control. Scientist sits at a computer to analyse the results of monitoring for pesticide pollutants in food. He is using a gas chromatograph that can find minute traces of pesticides in food or drink. A series of peaks on the computer screen displays the results. The gas chromatograph is seen at lower left. Pesticides are widely used in agriculture to deter pests. Chemicals in pesticides can persist in the environment and contaminate food chains. Some are poisonous and have been implicated in cancers. Effective monitoring can be used to check the safety of food and drink.
