TL;DR: In this paper, over 450 sediment samples from estuarine and coastal marine areas of the southeastern US remote from contaminant sources were analyzed for trace metals, and the covariance of metals with aluminum provided a useful basis for identification and comparison of anthropogenic inputs to southeastern US coastal/estuarine sediments.

TL;DR: The relationship of total and methyl mercury concentrations in fish to those of sediments from corresponding locations was fish-species dependent, in addition to several abiotic factors, and among fish species analyzed, hardhead cat fish, gafftopsail catfish, and sand seatrout contained the highest concentrations of mercury.

TL;DR: In this article, data on dissolved trace metal concentrations in east coast U.S. rivers from USGS, National Stream Quality Accounting Network are compared with data from collected and analyzed samples.

TL;DR: In this paper, historical profiles of metal accumulation have been generated for the lower St. Johns River and Hillsborough Bay, Florida, in cores representing approximately 50 yr of sediment and metal accumulation.

TL;DR: Purified diets with 0, 2, 4, 8, 16 and 32 mg supplemental copper/kg were fed for 16 weeks to channel catfish fingerlings and copper levels in liver were significantly higher in fish fed 32 copper/ kg than those fed the unsupplemented diet.
