MICRODIMENSIONAL ATMOSPHERIC POLLUTION OF THE SMALL INDUSTRIAL SETTLEMENTS OF THE PRIMORSKY REGION (DALNEGORSK, LUCHEGORSK, RUDNAYA PRISTAN)

Abstract

The article is devoted to the research of atmospheric suspensions of settlements of the Primorsky region: Dalnegorsk, Luchegorsk, Rudnaya Pristan by means of laser granulometry and mass spectrometry of high resolution. For control the border zone of the Sikhote-Alinsky Biospheric Reserve has been chosen. In Dalnegorsk and Rudnaya Pristan the prevalence in snow of firm particles up to 10 microns in size from 54 to 100% is recorded. In Dalnegorsk in snow in a water-soluble phase there is a big quantity of Fe, Ni and Cu, and near the enterprise «Bor» of Zn. In a water-soluble phase of the samples which were taken in Rudnaya Pristan, high concentration of Pb was revealed. In Luchegorsk near Regional Power Station microparticles of 10-18 microns in size in the proportion of 72% were found out, and in a water-soluble phase there was a sharp increase of Zn concentration, and moderate increase of Pb, Al and Fe. In two points on border with Sikhote-Alin Biosphere Reserve large firm particles (515.46-954.78 microns) were found and only in one point adjoining a highway there was the prevalence of microparticles (9-20 microns). Also there was high concentration of Zn in one of the points on the border with the reserve. It proves the fact that technogenic factors influence the conservation zone more and more.
