Aluminum smelting industry is implicated with documented health risks. This study examined toxic effects of aluminum smelting dust as a real-life chemical hazard instead of single aluminum compounds, which seldom exist in real life. Methods: Adult male rats were gavaged acute (3 consecutive days) and chronic (6 weeks) doses of two dust concentrations (10 and 20 mg kg-1). Experimental investigation included toxic metal accumulation and biochemical analysis of blood and liver. Result: Aluminum

Anemia, inflammation, liver and kidney damage and oxidative stress were established in view of thrombocytopenia (35%), leukocytosis (41%), lymphocytosis (55%) and alterations in aminotransferases, creatinine, malondialdehyde, superoxide dismutase and catalase. Aluminum facilitation of iron-mediated lipid peroxidation is suggested. These findings drew attention to the magnitude (dose-dependent) and persistence (time-dependent) of aluminum dust as health compromising and are of particular significance to workers in aluminum smelting industries.
