“…Mackereth (1966) suggested that coprecipitation of Co, Ni, Cu, and Zn with manganese and iron may be the dominant mechanism of transferring these metals from water to sediments in the English lakes. However, these elements were also inversely related to grain size, so that the association may be more of a clay-organic-trace element relation as described by Shimp and others (1971) for sediments from southern Lake Michigan, by Glenn and Van Atta (1973) for Columbia River sediments, by Oliver (1973) for Ottawa and Rideau River sediments, by Baker-Blocker and others (1975) for sediments in Grand Traverse Bay, Lake Michigan, and by Fitchko and Hutchinson (1975) for river sediments entering the Great Lakes. In other words, organic matter is usually concentrated in fine-grained sediments, and both materials may be enriched in trace elements, particularly the transition elements, by adsorption on clay minerals and/or organic complexing.…”

Analyses of 36 trace, minor, and major elements were used to classify the sediments of 46 Minnesota lakes. Q-mode factor analyses grouped Minnesota lake sediments according to clastic-, carbonate-, organic-, and redox-related elements. Carbonate lakes occur in west-central Minnesota; their sediments have relatively high concentrations of CaC0 3 , Ba, and Sr. Lakes with sediments containing more than 30% organic matter occur in east-central and northeastern Minnesota; these sediments have high concentrations of organic C, N, and H, and slightly elevated concentrations of Pb. Only three lakes have sediments included in the "redox" group, with relatively high concentrations of Fe, Mn, Mo, La, and Zn. High concentrations of redox-sensitive elements appear to be associated with oxidized iron and manganese minerals, but in Elk Lake, one of the three lakes in this group, a significant amount of iron and manganese is contained in iron phosphate, iron sulfide, and manganese carbonate. Clastic lake sediments are not diluted by large amounts of organic matter, carbonate minerals, or iron-manganese minerals, and are of two types: a western group derived largely from Cretaceous shales in the prairie regions, and a northeastern group derived from Precambrian crystalline rocks in the forested arrowhead region. Western clastic lake sediments have higher concentrations of Al, Na, K, B, Ba, V, Mg, and Sr. Most northeastern clastic lake sediments contain higher concentrations of Cu, Y, Be, and Ni, but several are chemically more similar to those of western prairie lakes.

“…Sediments may act as indicators of heavy metal burden in a coastal environment, as they are the principal reservoir for heavy metals (Fitchko and Hutchison 1975). Mangroves act as sediment trap and hence mangrove macrobenthos are susceptible to potential heavy metal pollution.…”

Heavy metal concentrations in some macrobenthic fauna have been reported for the first time from the Sundarbans mangrove forest, south west coast of Bangladesh, in the northern part of Bay of Bengal. The concentration of Fe, Cu, Zn, Cd and Pb in macrobenthos ranged from 235 ± 10.11 to 1,051 ± 38.42, 3.66 ± 0.89 to 7.55 ± 1.29, 76.8 ± 8.55 to 98.5 ± 6.49, 0.46 ± 0.11 to 0.859 ± 0.2 and 4.66 ± 1.17 to 6.77 ± 2.1 μg/g, respectively. Significant variations (p ≤ 0.05) in heavy metal concentrations have been observed among the mud crab, mudskipper and gastropod. However, heavy metal burdens did not vary significantly among the hermit and horseshoe crabs. In mud crab, horseshoe crab and gastropod, heavy metal concentrations were recorded in the sequence: Fe > Zn > Pb > Cu > Cd. Hermit crab and mudskipper contained heavy metals in the order of Fe > Zn > Cu > Pb > Cd. Fe and Zn concentrations were found significantly (p ≤ 0.05) higher in macrobenthos. The lead (Pb) concentration found in the edible portion of macrobenthos exceeded the international permissible limits certified by the WHO. Bioconcentration factors >1.00 obtained for Fe (17.05 in mudskipper) and Cd (1.87 in gastropod) indicated that these metals were highly bioaccumulated and biomagnified in benthic fauna of Sundarbans. The findings of this study refer to the potential impact of heavy metals in the mangrove ecosystem of Bangladesh.

“…These nearshore concentrations indicate that the principal inflow was from the Niagara River. A more generalized study (Fitchko and Hutchinson, 1975) provided data for 10 metals from the mouths of 116 tributaries to the Great Lakes system. Most of the tributaries that drained urban-industrial areas had elevated metal concentrations, while most of the relatively undisturbed tributaries did not.…”
