Experimental investigation of the effects of crude oil on two freshwater lake ecosystems
Technical Report
·
OSTI ID:5856519
The responses of two freshwater lake ecosystems (Bear Lake, Utah-Idaho, and New Fork Lake, Wyoming) to crude oil impaction were investigated in two phases. The effects were first studied on three phase (gaseous-aqueous-sediment) laboratory microcosms. Notable responses were increased oxygen demand, nutrient immobilization, reduction in plant biomass accumulation, and a heterotrophically dominated ecosystem. The second phase investigated the effects of crude oil on plant litter decomposition in the lakes.
