The Role Of Filter-Feeding Organisms In Concentration Of Suspended Solids Containing Kepone Into Bottom Deposits, Dexter S. Haven, Reinaldo Morales-Alamo

Reports

Filter-feeding marine animals such as molluscs, tunicates and barnacles filter particles as small as 1 micron from suspension during their feeding process and void them as fecal pellets. These settle at much faster rates than their component particles. Feces or pseudofeces which settle are termed biodeposits. Eighty-two to 93 percent by volume of the particles in the biodeposits of several species of molluscs are smaller than 4 microns; the range in size of those particles is about 1 to 10 microns (Haven and Morales-Alamo, 1973).

Uptake Of Kepone By Oysters Exposed To Contaminated Sediments Mixed With Lignite, Dexter S. Haven, Reinaldo Morales-Alamo

Reports

Preliminary studies conducted by personnel of the Allied Chemical Corporation at Morristown, N. J. suggested that coa] would be used to adsorb Kepone from an aquatic substrate. .The possibility of using coal to bind Kepone contaminating the natural environment indicated further preliminary exploration of the matter.

The Virginia Institute of Marine Science undertook a laboratory study with oysters under contract with the Allied Chemical Corp. to explore that possibility. Lignite was mixd on a 1:10 dry-weight ratio with sediments contaminated with Kepone.
