Metals and organic pollutants in snow surrounding an iron factory

To estimate air pollution snow samples were collected in March 2001 at six sites in the vicinity of the Kostomuksha factory in Karelia. Seventy-two chemical elements and more than 200 individual organic compounds were identified by inductively coupled plasma mass spectrometry (ICP-MS) and gas chromatography mass spectrometry (GC-MS). It was found that the levels of Li, B, Al, Fe, Ni, Cu, Zn, Hg, Mn, Mo as well as hydrocarbons, phthalates and phenols exceeded the existing maximum allowable concentrations. A list of toxicants emitted with the factory exhausts and a list of priority pollutants for Kostomuksha were compiled. The impact of the exhausts of the Kostomuksha factory on the environment in Finland is relatively small.
