ABSTRACT COMPARATIVE TESTS FOR SEPARATION METHODS OF ORGANOCHLORINE PESTICIDES IN MILK Adriana Chiş, Vasile Bara University from Oradea, Faculty for Environmental Protection Oradea, Romania In the case of food that contains more than 2%, OCP, is determined through separation, together with fat. This is why the comparison of various methods presented by the specialised literature through which it can be separated from milk fat, is very useful. The validity of the methods has been tested through the comparison of the determined values with the ones determined through the reference method indicated for the determination of milky fat. The application of various methods shows that there are not major quantitative differences; however, some of them are closet to the reference values. This thing is good to know in order to be able to apply in safety conditions, the fastest method, the less expensive or, simply, the most accessible in the laboratory that performs the determination. Keywords: organochlorine pesticides (OCP), fat, milk 1. INTRODUCTION Fat separation from milk is the first phase in OCP determination, from milk. Despite the fact that OCP usage has been limited due to the toxic effects and bioaccumulation, research on this kind of food contaminant is necessary because they occur under sanitary - veterinary surveillance (Savu C-tin and Georgescu Narcisa, 2004). The monitoring of food chemical contamination, is an essential compound of food safety and, according to Codex Alimentarius, it supplies valuable information on the identity of chemical contaminants for the selection of priorities in what regards their follow-up and limits. The program GEMS/FOOD (Global Environment Monitoring System/Food Contamination Monitoring and Assessment Program) of evaluation of the chemical contaminants level in foods, is essential to reach this purpose. According to this program we can observe that the determinations do not refer only to the primary foods such as milk and diary but also to the ones along the food chain, that can be responsible of contamination. In this regard we can state exemplify the cereals. The organochlorine compounds are followed to the total diets, as shown in Table 1 Table 1: Chemical contaminants under sanitary – veterinary surveillance – extract (after Hura Carmen, 2005 ) Contaminants Food Chlorine compounds: DDT (metabolites), HCH (isomers); polychlorine bi-phenyls, dioxins, etc. 453 Milk, powder milk, butter, eggs, animal and vegetal fat, fish, cereals, oil, mother milk, total diets (menu)
