"The summer loadings of bioavailable nonapatite inorganic phosphorus to the eutrophic Upper Bay of Quinte, Lake Ontario, are reported on for rivers, sewage treatment plants, and in-place sediments. All three sources have a highly seasonal component. Increasingly over the summer, diffusional reflux from the in-place sediments becomes the dominant source of bioavailable phosphorus. Most of the load of riverine inorganic phosphate ion, incorporated into hydrated ferric oxides, is not deposited to the organic sediments within Upper Bay; it is considered to be weakly bioavailable as it transits the Bay in oxic suspension. Remedial action to control eutrophication hinges on reducing the rate of accumulation of nonapatite inorganic phosphorus in the bottom sediments. This means severe controls on the loadings of riverine particulate matter to the Bay of Quinte"--Abstract. gccst Lakes gccst Sediments gccst Water pollution gccst Pollutants Canada.
