Abstract
The article presents the results of toxicological assessment of the polymer material «Penoplex». The above material is made of expanded polystyrene and is used in many areas of production, including to reduce heat loss of livestock facilities. Hematological studies of experimental and control animals revealed no differences in clinical parameters of the blood of white rats, the serum content of total protein, immunoglobulins and sulfhydryl groups. The polymer material «Penoplex » does not have a negative effect on the indicators that characterize the immunity of animals and the antitoxic function of the liver. Significant differences of coefficients of the mass of the internal organs of the control and experimental groups of rats, kept in a cage with a polymer material «Penoplex », did not reveal. This indicates that the material «Penoplex» does not have a negative effect on the mass of the liver, kidneys, spleen and heart. The results of the research also indicate the absence of toxicity of the polymer material «Penoplex».
