Correlations between the Degree of Heavy Metal Contamination of Fodder and their Accumulation in Organs and Tissues
Keywords:
cadmium, cows, fodder, leadAbstract
Research aimed at establishing an association between the level of heavy metals (Pb, Cd, Cu and Zn) in fodder, chronic diseases at cows and residual heavy metals in different organs and tissues. The toxicological investigation revealed the following main pathological states in cows: 18% marasmatic syndrome with toxic and deficiency etiology, 20% lung affections, 18% hepatopathia and under the 10% gastric diseases. The hematological and biochemical examinations revealed hyporegenerative aplastic anemia, hypophosphatemia, liver and kidney dysfunctions, bone and joint dysfunctions. Lead retention in the liver was 0.62 ppm (HAL 0.5 ppm) and cadmium was 0.82 ppm (HAL 0.05 ppm). Lead retention in the kidney was 1.05 ppm (HAL 0.5 ppm) and cadmium was 2.13 ppm (HAL 0.05 ppm).
