Chemical Contamination of Food and Its Impact on Population Health in Arkhangelsk Region

Abstract

Food contamination in the Arkhangelsk region has been studied. The average concentration of nitrates (82.4 mg/kg) in vegetables and fruits of local production was 1.4 times higher comparing to the hygienic standard. The hazard index (HI) and the individual cancer risk index (CR) were used to study contaminants impact on health. Non-cancer risk was dangerous for the nervous (HI = 4.9), cardiovascular (HI = 4.4), immune (HI = 4.7) systems, skin (HI = 4.3), the hormonal exchange (HI = 5.2) and the digestive apparatus (HI = 5.3). The total cancer risk was high ^R = 1.9 х 10 -3) and associated with fish contamination by arsenic (95.2 %).

Estimation of the Enzymatic Activity of Haplic Chernozem under Contamination with Oxides and Nitrates of Ag, Bi, Te and Tl

“…The increased content of bismuth in the soil leads to its accumulation in plants [23,[31][32][33][34][35]. By transmitting through food chains, bismuth enters the human body, causing numerous pathologies [36][37][38][39][40]. The scale and degree of tellurium contamination of soils and agricultural plants are increasing every year [17,[41][42][43][44][45][46].…”
