Distribution of Cadmium and Lead in Liver and Kidney of Some Wild Animals in Slovakia

Abstract

The content of cadmium and lead, as risk factors of environment, in liver and kidneys of wild animals as brown hare (Lepus europaeus), yellow-necked mouse (Apodemus flavicollis), wood mouse (Cleithrionomys glareolus), and red deer (Cervus elaphus) were studied. Samples were analyzed by the atomic absorption spectrophotometry method (AAS). The highest levels of cadmium were found in kidneys (0.213-2.387 mg/kg) of all animal species. The concentration of cadmium in liver was 0.032-0.258 mg/kg. The analysis of lead showed that the concentration of this element was higher in kidneys of yellow-necked mouse and wood mouse (0.503-0.780 mg/kg) than in liver (0.177-0.268 mg/kg). In brown hare and red deer a higher accumulation of lead in liver (0.221-1.904 mg/kg) in comparison with kidneys (0.115-0.561 mg/kg) is reported.

Model trial investigating retention in selected tissues using broiler chicken fed cadmium and humic acid

“…Kramarova et al (2005) investigated Cd levels in livers and kidneys from wild animals. The highest levels were found in the kidneys (0.213-2.387 mg per kg) of various species.…”

Protective Effect of Zinc (Zn) on the Histology and Histochemistry of Liver and Kidney of Albino Rat Treated with Cadmium

“…Therefore, Cd pollution was internationally recognized as the most important environmental health hazard that remains to be eliminated [17]. When Cd is taken into the human body through the oral route by the ingestion of contaminated water or food, it accumulates in the liver and kidneys and its half-life is very long, exceeding 10 yr [10,18].…”

Assessment of Lead and Cadmium Status and its Effect on Biochemical Profile of Cattle Reared Around Industrial Effluent Contaminated Area

“…Pb and Cd do not have any detectable beneficial biological roles in the body. On the contrary, their detrimental effects on physiological, biochemical, and behavioral dysfunctions in animals and humans have been documented (Kaji et al, 2004, Kramarova et al, 2005. Meerut district stands first in Uttar Pradesh and 39 in all India with about 8,244 small scale industrial units.…”
