This paper describes a study of the degree of bioaccumulation of an organochlorine insecticide called Lindane in tissues of broilers and pigltes, from known amounts of Lindane contaminated feed mixes. In commercial feed mixes, for both animal groups, residues of Lindane were found in approximately 100-200 times lower concentrations than those cited in the Book of Regulations. This information shows that the allowed concentration of Lindane in feed is, too, high. Residual content in all the examined kinds of samples of the experimental group of the animals, that were fed over 30 days, is two times lower that the concentration citated in the Book of Regulations, was higher that the permited concentration of Lindane. Increased of the residual content of Lindane in the tissues of broilers was 30-338 times, and for the piglets 50-820 times higher than it was in control group. Feeding of broilers with Lindane lasted 30 days, and the usual period of feeding the broilers is about 50 days. For 30 days the piglets were fed with feed that contains Lindane, but the regular time of fattening is 6 times longer. It can only be presuposed what is the residual content of Lindane that animals received through feed during the period of fattening, because this insecticide shows a distinct ability for bioaccumulation and high stability in fat.
