TECHNOGENIC ANOMALIES IN THE ABANDONED TAILINGS OF GOLD MINING: ELECTROPHYSICAL AND GEOCHEMICAL DATA

The tailing dump of the Komsomolsk gold-mining plant is considered. The aim of the work is to study the composition of mining waste and the directions of migration of drainage using electro-tomography and geochemical methods, as well as determining the variability of electrophysical parameters and composition of the man-made environment depending on temperature. The results of a laboratory experiment to determine the concentrations of CS2, C2H6S, (CH3)2SO above the surface of the waste substance are given.

Heavy metals in soils of the train removal station Ussuriysk JSC Russian Railways

The paper studies heavy metals in soils of the train removal station Ussuriysk JSC Russian Railways. An adverse effect of railway transport on adjacent territories is shown. Railway transport and subjects of its support are permanent sources of pollution. Long-term emissions to the air are reflected by essential accumulation of tocsins in the top horizons of the soil. The authors reveal the amount of heavy metals in soils of the train removal station Ussuriysk JSC Russian Railways. To identify the coefficient of heavy metals concentration in soil samples of 8 trial areas of technogenic and anthropogenic zones of the city were analyzed. To identify local technogenic anomalies concentration coefficients were calculated. The authors concluded that the territory of the train removal station Ussuriysk JSC Russian Railways was very polluted. The south of the railway station is characterized by an average pollution level. The authors revealed high concentrations of Zn, Mn, Fe, Cu and Pb in soils of the trial sites with a high transport loading.
