In the influence area of an industrial platform there were harvested organs samples, blood samples and bone samples from cattle and horses, already dead or slaughtered in necessity in three localities: Axente-Sever, Copsa Mica and Seica Mica. Determination of lead and cadmium from harvested samples was made by atomic absorption spectrometry, estimating the absorption of radiation at strength wave of 228.8 nm for cadmium and at strength wave of 283.3 nm for lead. The analysis of the obtained results was made in compliance with the stipulated standards. The researches led to the following conclusions: - regular values for lead and cadmium in blood samples are exceeded by 2 times for lead and by 5 to 13 times for all samples and sampling points; - lead admitted concentration is exceeded in all cattle organs samples; the exceeding was about 1.34 to 45.7 times - the highest concentration being noticed in kidney, liver, spleen and heart; - cadmium admitted concentration was exceeded by 2 to 20 times for all samples and sampling points; - in horse organ samples, lead concentration was exceeded by 2 to 41 times and the cadmium concentration by 2 to 192 times; - for bone samples lead concentrations reveal an exceeding by 3 times and the cadmium by 5 to 10 times; - the high concentrations of lead and cadmium which are detected in the analyzed samples (organs, blood and bone samples) proves a massive pollution for this area and also indicates chronic toxicosis of animals.
