| The environmental effect and fate of several agricultural and industrial source toxicants were evaluated in controlled laboratory microcosm systems in the presence of the aminopolysaccharide polymer, chitin. Toxicants examined included methyl parathion, phenol, pentachlorophenol, 2,4 dichlorophenol, 1,2 dichloroethane and Kepone. Microcosm operating parameters, including pH/Eh, salinity, temperature, flow rate and sediment/water interface conditions, were based on comparable in situ measurements. Fate analysis predictions were based on mineralization of the parent toxicant compound as measured by chromatographic analysis or super(14)CO sub(2) expiration. Chitin, amended to continuous flow microcosms, promoted either cometabolic or cooxidative... |

| Discolored waters and human diseases by shellfishes were dominant features of summer 1983 in south coast of Brittany. Vilaine Bay, the most damaged area, was successively affected by brown waters in early June, and diarrhetic intoxications by harvested mussels (July and August), just as DPS producing dinoflagellate (D. acuminata ) reached higher water or mussel guts concentrations than years before. Outspreading in the whole south coast of Brittany and possible relation with hydrological or biological parameters are analyzed. |
