| Summary: | (Trip H), and 1350 ppm (Trip V). Metal enrichments at depth airborne inputs from facilities located at the Tex Tin site area. I determined trace metal concentrations in water, by a hurricane protection levee. An industrial waste closely reflect those in sediments of the Wah Chang Ditch. concentrations in Wah Chang Ditch water were very elevated different trips, respectively averaging 1250 (Trip 1), 893 disposal facility (Gulf Coast Waste Disposal Authority) is each location. Oysters show higher concentrations in most environmental metal concentration in the sediments from which Fe, Mn, and Sn. The variabilities and geographic trends in Galveston Bay and other U. S. Gulf of Mexico oysters. The have been concerns about possible metal contamination in this higher in oysters. For organisms collected from the Swan in Swan Lake are enriched in most metals relative to in the sediment column indicated that the Swan Lake area has influence the natural concentrations of Fe, Al, and Ni in Lake area trace metal concentrations were generally in the located north of the Wah Chang Ditch. Consequently there metals relative to Galveston Bay and other Texas bay metals than those in mussels. The Zn level was II 3 times mussels in this study do not reflect the unusually elevated order oysters > snail > crab > shrimp > fish. Metal Pb, Se, Sn, and Zn. Water samples were analyzed for Cd, Cu, received runoff from a tin smelter via the Wah Chang Ditch recently received less input of metal contaminated sediment relative to those of the Brazos River and Galveston Bay and sediment trace metals indicated that waste disposal and sediments either in the past or at present. Most organisms sediments, and organisms (oyster, mussel, snail, crab, fish, sediments. Lead especially was uniformly high on the three sediments. Sediments in the study area showed elevated trace sediments. Three different samplings of the Wah Chang Ditch seemed to be directly related to sediment concentrations at showed no temporal patterns in metal distribution in the showed very small spatial variations. However, the oysters shrimp, and spartina) in the area. Sediments and organisms Swan Lake is a sub-bay of the Galveston Bay system. The area than in the past. Anthropogenic inputs did not greatly they were taken. Iron and Pb concentrations in oysters were analyzed for total Ag, Al, As, Cd, Cu, Fe, Hg, Mn, Ni, were likely sources for metal pollution found in the which ran through it in the past but the ditch is now cut off |
