Our study assesses environmental lead and fluoride pollution in West Pomeranian forests in Poland, on the basis of chemical analysis of antlers and skull bones of roe deer (Capreolus capreolus L.) from the surroundings of Szczecin and Drawsko Pomorskie, Poland. Lead was measured by atomic absorption spectrometry, and fluorides by using an ion-selective electrode. Our study indicates greater lead contamination...
The aim of this study was to determine whether oral supplementation of melatonin (M), a known antioxidant, free radical scavenger and metal chelator, influences lead (Pb), calcium (Ca) and magnesium (Mg) distribution in the blood, bones and teeth of rats exposed chronically to lead. The studies were carried out on male Wistar rats which, from their birth until reaching sexual maturity (for 3 months),...
Although many countries now have programs to lower the levels of lead in the environment, human exposure to Pb remains of concern to public health officials worldwide. The mechanisms of lead toxicity are still not fully understood, but recent findings have recognized the significance of the lead-induced impairment of the cell energy metabolism. This review outlines recent hypotheses and evidence on...
For the purpose of this work an epiphytic lichen species, Hypogymnia physodes (L.)Nyl., was used. Thalli of the lichen were treated with solutions of nitrate salts of heavy metals, including Zn(NO3)(2), Cu(NO3)(2), Pb(NO3)(2), and Cd(NO3)(2). To simulate the acid rain impact, pH of the metal mixture was lowered to pH 4, using Na2S2O5. Content of heavy metals was determined after a standard UV mineralization...
