Technological aspects of determination and distribution of pesticides in oils, cake and meal

The paper deals with the problem of determination of pesti­cides and the study of their distribution in oils, cake and meal. The necessity of monitoring and rapid response to critical points of the content of pesticides in oil crops and products of their processing is shown. The data concerning the influence of oil extraction conditions on the residual amount of pesticides within the chemical class of some pesticides, which are commonly used in the cultivation of oil crops, was obtained taking into account the properties of a particular preparation and oil extraction technolo­gies. The results of studies of the distribution of residual amounts of metalaxyl, imidacloprid and thiacloprid in seeds of sunflower and the products of its processing - cold-pressed unrefined oil, cake, extraction oil and meal in relation to sunflower seeds are given. The dependence of the “behavior” of pesticides on their polarity within the same class (nikotinoids) and other chemical group (fenilamids) was found.
