| Abstract |
The fate of methyl parathion and the development of biological communities were examined as a function of inorganic nutrient enrichment, inorganic nutrients plus glycerol and presence of sediments in two eight-compartment, continuous-flow microcosms. First-order degradation rates of methyl parathion were related to the different nutrient treatments, with higher rates associated with the organically enriched environments. A stable state was generally established in each compartment after six weeks of development. Aufwuchs biomass dominated the systems and observed differences (alpha=0.10) in nutrient concentrations were reflected by differences (alpha=0.05) in some aufwuchs structural parameters and in community function. Inclusion of sediments had no significant effect on any of the parameters measured. |
