Environmental contextLead is a toxic trace element, widely distributed in the Arctic environment as the result of both natural and anthropogenic processes. High-precision measurements of lead’s isotopic composition are used to distinguish the possible sources and track the transport pathways of this toxic metal. These measurements can provide unique global information on the history and status of lead contamination. AbstractPublished data of lead isotopic ratios in the Arctic environment have been gathered in a dataset file (available as supplementary material) and reviewed to summarise the main information obtained for the different environmental compartments (atmosphere, cryosphere, lithosphere, hydrosphere and biosphere). The analytical procedures applied to achieve the precise measurement of this important environmental proxy are also illustrated and discussed. Finally, a general overview of the sources of atmospheric lead across the Arctic is provided.

Heavy metals as pollutants in the working and living environment are a serious health and environmental problem because they are toxic, non-biodegradable, accumulate in living systems and have a long half-life in soil. Sources of lead contamination are combustion products in the chemical industry and metallurgy, industrial waste water, landfills, traffic etc. Lead enters into the body via the food chain and drinking water. In the body lead is deposited in the liver, kidneys, brain and mineral tissues. Excretion of lead causes damage to the epithelial cells of certain organs. High level exposure to cadmium is usually the result of environmental pollution by human activities. Exposure to cadmium can lead to acute and chronic tissue damage of various organs, including liver and kidneys in humans and in animals. In this paper we analyzed the effects of lead and cadmium exposure, in working and living environment, on the model system of experimental animals, particularly the activity of certain liver enzymes, acid and alkaline DNase, and standard biochemical blood parameters. The study showed that lead and cadmium significantly affect the protein content, red blood cells, hemoglobin and hematocrit, and the activity of liver enzymes. This harmful effect of this toxic metal can be reduced by the supplements.
