To establish the priority pollutants in the atmosphere of Moscow in winter 8 snow samples were collected along the perimeter (109 km) of the Moscow belt road. Mass spectrometry was used as an analytical tool to identify individual organic compounds (gas chromatography/mass spectrometry) and the most environmentally relevant chemical elements (inductively coupled plasma with mass spectrometric detection). As a result several hundred organic compounds belonging to various classes, including representatives of the list of priority pollutants of the USA Environmental Protection Agency were identified. Their levels as well as the levels of chemical elements were quantified. The importance of accurate mass measurements for the efficient structural elucidation and reliability of quantitative measurements has been demonstrated. The data obtained allow estimating atmospheric pollution in Moscow in the period between December and March and proposing a list of priority pollutants for the atmosphere of Moscow.
