Analysis Of Chemical Contaminants In Tissue Samples From Two Species Of Fish, Michael David Reive

Theses

Interaction of marine species with chemical pollutants within the marine ecosystem is extremely complex and difficult to interpret. The purpose of this thesis was to investigate the effect of an exposure of treated municipal wastewater on winter flounder (Pseudopleuronectes americanus) and striped bass (Morone saxatilis). Fish from two locations were exposed to different concentrations of wastewater. Half of the fish from each tank were sacrificed, and the remaining fish were given a depuration period in unpolluted water. Tissue samples were composited, soxhlet extracted and passed through a florisil cleanup column. Gas chromatography, was used to analyze for hexachlorobenzene, hexachlorobutadiene, Aroclor …

Impacts Of Treated Municipal Waste-Waters On Development And Growth Of Hudson-Raritan Estuary Fishes, Chien-Min Chen

Theses

The Hudson—Raritan Estuary, known as one of the worst polluted estuaries in the world, receives pollutants from many point sources. Treated municipal wastewater (TMW) counts for 13% of its total freshwater input and more than 98% of the chemicals classified as priority pollutants been infused. Because of the complexity of the input, treatment facilities cannot remove toxicants efficiently. In addition, generation of new compounds by water treatment such as chlorination occurs. Batch-to-batch variability in the chemistry of this effluent was reflected in the early life stage toxicity bioassays using mummichog (Fundulus heteroclitus) and winter flounder (Pseudopleuronectes americanus) embryos.

TMW has …
