The interstitial waters show biogeochemical gradation, with sulphate reduction under the water-sediment interface, followed by nitrate reduction at greater depth. This involves sub-lacustrine light flux of nitrates. Advection-diffusion m

Sediment distribution on a current-dominated lake delta (Versoix delta, Lake Geneva, Switzerland),ersoix delta (. of Lake Geneva, Switzerland), has been studied in order to determine the role of wind-driven currents on transport and sedimentation of suspensions. Research included the study of sediment distribution in the lake basin, of currents due to wind forcing and modelling of lateral partic

High levels are registered from about 1960 to 1975. Recent surface sediments have low levels again. PCB and PAH
