Includes bibliographical references. "Thirty two sediment samples were collected from selected sites at coal mines and coal-fired power plants across Canada. Elevated concentrations of some contaminants and toxicities were observed, when compared to those in uncontaminated sediments. The samples from the Souris River upstream, the Trenton power plant ash lagoon cenospheres, the Salmon Harbor mine lake water, and the Phalen colliery surface runoff contain several high concentrations of metals. The sediment from the Phalen colliery surface runoff brook has very high Cd and Fe concentrations. The Prince colliery downstream discharge contains elevated concentrations of PAHS; the Souris River upstream sample also has fairly high PAHS concentrations"--Abstract. gccst Sediments gccst Water pollution gccst Mining industry Canada.
