        The occurrence of harmful algal blooms has resulted in growing worldwide concern about threats to aquatic life and human health. Microcystin (MC), a cyanotoxin, is the most widely reported algal toxin in freshwaters. Prior studies have documented its presence in aquatic food webs including commercially important fish and shellfish. In this paper we present .   A recent report from William & Mary’s Virginia Institute of Marine Science offers mixed news concerning the persistent issue of Kepone contamination in the James River. The good news is that.

Get this from a library. Predicting pollution in the James River Estuary: a stochastic model. [Harry Bard; Richard G Krutchkoff]. Distribution of benthic communities in the estuarine portion of the James River was controlled mainly by salinity.

Pollution effects were localized and difficult to assess because of a rigorous physical environment. Mesohaline and oligohaline communities were very similar to those in other estuaries of the eastern United by: Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

KEPONE AND THE JAMES RIVER Robert J. Huggett College of William and Mary ABSTRACT The James River in Virginia was contaminated by the pes- ticide kep one when the material entered the river as early as Alkalinity and pH in the southern Chesapeake Bay and the James River estuary Article (PDF Available) in Limnology and Oceanography 24(5) September with 84 Reads How we measure 'reads'.

Distribution of benthic communities in the estuarine portion of the James River was controlled mainly by salinity. Pollution effects were localized and difficult to assess because of a rigorous physical environment. Mesohaline and oligohaline communities were very similar to those in other estuaries of the eastern United States.

Macrobenthic densities were most severely depressed Cited by: Richmond, VA -- In anticipation of Halloween, Environment Virginia unveiled What's Brewing in the James: Ten Scariest Water Facts, showing that, while improving, a terrifying concoction of chemicals, bacteria, and other pollutants still plague the James and Virginia’s waterways.

“Halloween is the season to be scared, but Virginians shouldn’t have to be afraid of swimming, fishing and floating down the James River. The observed salinity distribution in the Columbia River Estuary is used to predict the flushing times for various river discharge rates, varying tidal ranges, and varying salinity intrusions.

Unlike the situation described earlier for streams and rivers, pollution in lakes and wetlands is often easily visible through effects on water quality (e.g., taste and odor problems in municipal drinking supplies), primary.

This model helps users interpret and predict water quality responses to natural phenomena and manmade pollution for various pollution management decisions.

originally anticipated, and the effect on the river was dramatic, both in terms of dissolved oxygen level and in the recovery of the ecology of the region (Cock-burn, ).

The completion of these and other works has resulted in a reduction in the pollution load discharged to the estuary in recent years of nearly 80 per cent as shown in Figure. The historical relationships among discharge, salinity, and the duration of saltwater intrusion were established quantitatively and demonstrate that (1) the lower is the river discharge, the higher is the salinity and the longer is the residence time of saltwater in the estuary, and (2) the threshold value of the river discharge for salinity.

Together we can protect Virginia’s greatest asset: America’s Founding River. The James River is a River at Risk. Now is the time to begin a conversation on how to protect our waterways and our citizens from the threats posed by the storage and transport of hazardous materials.

The effects of channel deepening on the salinity and density flow in the James River estuary, Virginia, were studied to predict changes that might affect oyster production.
