[The identification of new pesticide preparations in biological material]

Twelve color reactions and chromatography in a thin layer of adsorbent are proposed for identification of foreign pesticides. Solubility of the agents is studied, optimal common extractant selected, and universal method for isolation and identification of 19 new pesticides tried on the liver. The sensitivity and specificity of the method is assessed: it is as high as 0.5 to 1.5 mg%.
