【Abstract】 A biochemical method for rapid detection of organophosphorus and carba-mate pesticides in water has been developed. The method is based on the observation of the color developed by adding to the water sample a kind of enzyme tablet, together with a colorforming substrate tablet. Qualitative identification and quantitative estimation are accompanished by comparing the color intensity with those developed for known pesticides of different levels. The sensitivity of the method is in the range of 0.1-3.0ppm for most organophosphorus and carbamate pesticides. The method needs no expensive apparatus; it is rapid and convenient, and can be used in the field.更多还原
