metadata.value: An ecogeochemical assessment of the state of the environment of the Vasileostrovsky district of St.
  Petersburg based on the monitoring of the content of heavy metals (Pb, Zn, Cu, Cr, Ni) in snow cover
  and soil was carried out. It was established that in soils the average concentration coefficient of the
  elements under study decreases in the series Zn > Cu> Pb> Cr > Ni. Authors considers the method
  of estimating the spatial heterogeneity of distribution of heavy metals in urban soils within the area
  of the “envelope” sampling method. It was revealed that, in general, the variation within the standard
  “envelope” area is equal to 30 %. Authors proposed a “principle of minimizing the possible harmful effects of chemical contamination of soils” based on the measured value variations. For example, the distribution of total index of soil contamination within the Vasileostrovsky district of St. Petersburg shows that the accounting errors of sampling soil using the “envelope” sampling method associated with natural uneven areal distribution of heavy metals, can significantly affect the definition of the category of soil contamination. The difference between soil and soil contamination in the northern, central and western parts of the Vasilievsky island became more clearly visible — the latter turned out to be less contaminated. It was established that zinc determines the total snow cover contamination index, as well as in the case of soil. However, the series of concentration decrease looks different: Zn > Ni > Cu > Cr > Pb. A high positive correlation was found between the coefficients of zinc concentration in the snow cover and soil, which may indicate a constant supply of this pollutant to the components of the environment. A similar pattern was noticed for the total pollution index. The most noticeable difference was noted in the contamination of soil and snow cover by lead. For soils lead concentration determines the total pollution index. In snow lead content is at the background level. This may indicate that at present the intake of lead into the atmosphere is noticeably lower than 10 years ago. Refs 11. Figs 5. Tables 3.
