Toxicity of oil sands to early life stages of fathead minnows ( Pimephales promelas)
Abstract The present study examines the effects of exposure to oil sands on the early life stages (ELS) off fathead minnows ( Pimephales promelas ). Sediments within and outside natural oil sand deposits were collected from sites along the Athabasca River (AB, Canada). The ELS toxicity tests were co...
