Acidic deposition and human exposure to toxic metals

摘要: Acid precipitation affects the solubility of several metals in aquatic systems and soil. Cadmium levels tap water samples from geological areas having low resistance to acidic pollution were significantly higher than those a neighbouring reference area where there was different structure. The median cadmium pH values 0.14 microgram l-1 5.6 respectively, for compared with 0.07 6.4 respectively area. Further, significant inverse relationship between both lead contents samples. mobility thus dependent on acidity. blood 195 subjects lower 91 (medians 60 vs. 70 micrograms l-1); no differences found or mercury levels. Subjects had plasma selenium 85 90 difference mainly attributed private wells. data may indicate negative effect intake via and/or foods. There also positive fish one hand other, which is accordance role as source these metals.
