Evaluating health risk caused by exposure to metals in local foods and drinkable water in Pechenga district of Murmansk region

Abstract

Total average daily intake of metals with local food by natives equalled: Cu 2%, Pb 6%, Cd 22%, Hg 40%, Ni 66%, As 157% - in comparison with allowable daily intake. Mushrooms are responsible for total intake of 35% Pb, 55% Cu, 61% Ni and 91% Cd; fish gives 83% Hg and 75% As. The natives' exposure to Ni is caused by mushrooms, wild and cultivated berries and vegetables, exposure to Cd - by mushrooms, that to Hg - by freshwater fish, exposure to As - by salmon and cod. Drinkable water contribution into exposure to metals is negligibly small for Hg, Cd, Pb and Cu, mild for As and considerable for Ni (23%). Total carcinogenous risk with Cu and Pb are negligible, with Cd is 0.22, with Hg 0.39, with Ni 0.81, with As 1.62, with totality of metals for total foods and water - 3.1. Total carcinogenous risks with Pb are minimal (less than 10-6), with Cd - allowable (less than 10-5), with As - average (less than 10-3), with Ni - high (10-2), with totality of metals for total foods and water - 1,25x10-2. Increased health risks revealed necessitate recommendations on reduction/exclusion of some local foods intake by the natives and measures on drinkable water purification from nickel, or usage of other sources of clear water.
