TL;DR: In this paper, the emissions from anthropogenic sources now exceed the flux from natural sources, implying that mankind has become the key element in the regional and global cycle of most of the trace metals.
Abstract: The emissions from anthropogenic sources now exceed the flux from natural sources, implying that mankind has become the key element in the regional and global cycle of most of the trace metals. The source inventories presented suggest that the Mn/V, Mn/Sn and Mn/Ni ratios are the most useful tags of air pollution from the burning of fuel oil while the Mn/Mo ratio can be regarded as best suited for fingerprinting the contributions from coal combustion. In future, the emissions of trace metals from refuse incineration and the contributions from the developing countries are expected to be of growing concern. Biogenic processes are recognized in this report as being particularly important in the natural flux of trace metals into the atmosphere.

TL;DR: Ashraf et al. as discussed by the authors reported trace metals in fish, sediment and water from three freshwater reservoirs on the Indus River, Pakistan, and found no correlation between the trace metal contents in water, sediment, and fish.

TL;DR: Spatial distribution maps show that the harbor area of Wilhelmshaven may be a particularly important source of metal, and even the metals of the second group are enriched by at most a factor of two relative to the local background, suggesting minimal anthropogenic impact.

TL;DR: Water samples were collected from unpolluted waters in southern and northern Sweden to show the range of natural trace metal concentrations, and results do not indicate any significant differences in metal levels between the two study areas.
Abstract: Water samples were collected from unpolluted waters in southern and northern Sweden to show the range of natural trace metal concentrations. The results do not indicate any significant differences in metal levels between the two study areas. Negative correlations with pH exist for total concentrations of Cd, Pb, Al, Mn and Zn. The dissolved (dialysable) metal fractions also increase with increasing acidity. The concentration of humic substances influences the distribution of Fe, Mn, Al, Pb, Cr, Co and As, as shown by positive correlations with water colour.
