- Abstract
Proteomic analysis technology helped to study and assess protein profile of blood serum in residents of area influenced bymetallurgic industrial releases. Findings are that poor quality of ambient air in populated area concerning concentrations of vanadium, nickel, manganese (up to 24-44 RfCchr) and stable presence of these elements in drinkable water (up to 0,006 RfD) cause mainly aerogenous chronic exposure at 0,00025-0,0022 mg/(kg-day). The exposed individuals demonstrate higher (3,5-3,8 times vs. unexposed ones and reference level) serum level of vanadium (0,0023 to 0,003 mg/dma), nickel (0,06-0,11 mg/dm) and manganese (0,036-0,048. mg/dm³). The authors demonstrated changes in serum proteomic profile associated with serum levels of vanadium and nickel (share contribution of vanadium and nickel equalled 15-20%) and manifested as increase of relative volume of transtyretine, apolipoprotein A-I, lower relative volume of haptoglobin. Increased serum level of vanadium disorders transport of apoproteins incorporated into lipoproteins; increased serum level of nickel activates hemolysis of RBC, disorders speed of hemoglobin-haptoglobin complex formation and its subsequent utilization by hepatocytes. Revealed molecular and cellular disorders enable to forecast thyroid disorders, hematologic diseases, cholesterol metabolism disorders.
