Mid-year Project Review for Research Theme Area #5: Environment

Stuart Environmental Sciences, Canadian Nuclear Laboratories Radionuclides in the water of the Laurentian Great Lakes and tributaries We have sampled water from 41 major tributaries of the Great Lakes; 26 in Canada (spring and fall) and 15 in the USA (summer). [...] We have also sampled water and suspended particles from 12 major basins of the Great Lakes (summer( and all 6 outlets (spring and fall). [...] Radionuclides in soil and plants of the Laurentian Great Lakes basin We have sampled soil and plants from 51 sites in the Laurentian Great Lakes basin. [...] Historical data on radionuclides the Laurentian Great Lakes basin We have compiled a time series of historical data on radionuclides in the Laurentian Great Lakes basin fallout, soil, sediment, water and biota from journal publications, gray literature and monitoring data. [...] Radionuclides and stable analogues in Laurentian Great Lakes biota By measuring radionuclides and stable analogues in water and zooplankton, and sediment and benthic invertebrates, we will determine transfer factors for primary consumers that can be used as input (food) for fish in foodweb biokinetic models.
