Levels of cadmium in the environment have drastically increased over the last decades, as a result of human activity. This cadmium pollution is transferred to the human food chain resulting in elevated concentrations in some foods such as vegetables and grain crops, animal liver and kidney and especially seafood. Cadmium ingested by animals and humans, accumulates mainly in the renal cortex and may result in a variety of toxic effects, such as renal damage, bone degeneration and cancer. Taking into account the rather elevated concentrations of cadmium in offal and seafood appearing in the international literature, a continuous control of such products is suggested as necessary in order to protect consumers from any undue exposure to this heavy metal.

“…Digestion of dry brain samples was performed in a medium with nitric acid and 30% hydrogen peroxide (Krachler et al, 1996). The lead acetate content in brain homogenates was measured by atomic absorption spectrophotometry (Perkin Elmer 1100 B) (Chakraborty et al, 1996).…”

Environmental exposure to toxic levels of lead (Pb) occurs in a number of industries with potential adverse effects on the reproductive capacity of exposed men. Clinical and animal studies indicate that abnormalities of spermatogenesis result from toxic lead exposure, but eventual histopathologic alterations involved have not been identified. To explore putative abnormalities in the reproductive gonadotropic axis following lead intoxication, experimental animals when exposed to low levels of lead, 65 days old animals were treated with distilled water containing 0,0 mg (control), 10 mg lead (Pb)/Kg/day and 15 mg lead (Pb)/Kg/day intraperitoneally for 20 days. At the end of treatment, the animals were sacrificed and the blood collected for luteinizing hormone (LH) and testosterone assays. The testis was processed for histological analysis. The results showed a high serum concentration of LH and testosterone in lead-treated animals compared to controls. Histological examination of testis showed deformities in testicular morphology of lead intoxicated animals with gross damage within the somniferous tubules. A strong correlation was established between LH and testosterone suggesting an alteration in the endocrine components of the gonadotropic axis. Histological examination of pituitary gland showed some degenerative changes in endocrine cells of lead group. Changes in LH and testosterone levels suggest that Pb exposure during the critical time of sexual differentiation induces reproductive axis abnormalities in adulthood. In conclusion, lead has a gonadotoxic effect by decreasing LH and testosterone levels and damaging the testis seminiferous tubules. Catalase activity was significantly reduced in the lead group following 65 days of exposure which possibly indicates that lead might had other mechanisms of action, such as increasing oxidative damage.
