S.P. Timoschuk S.S. Voronich POTENTIAL OF ANALYTICAL METHODS FOR THE ANALYSIS OF POLLUTING SUBSTANCES IN SOIL
Analytical Laboratory, Moscow Department of Nature Use and Environmental Protection (GUP “GPC” DPiOOS), Moscow, Russia

The ground of city of Moscow is exposed to pollution from the whole complex of various sources. Negative daily influence leads to irreversible changes of its chemical, physical and chemical properties and, as consequence, to deterioration of conditions of residing of the population. In this connection the importance of laboratories with a representative complex of analytical methods of the analysis with a main function of control and regulation of quantity of active polluting substances annually increases.

The report focuses on the possibilities of a number of modern analytical methods for chemical analysis that can be applied at control over a wide spectrum of polluting substances in the ground. To such a photocolorimetry, a fluorometry, an atomic absorption spectroscopy, a liquid chromatography, a chromatography-mass spectrometry, and also the laser-spark method of the analysis based on excitation in the environment, or on its surface, a laser spark with the subsequent spectral analysis of the received laser plasma by comparison of the received spectra with standard of a database of spectral nuclear lines, first of all, are carried. The method is used for definition of the maintenance of heavy metals (As; Be; Co; Cd; Cu; Mo; Wi, Pb; Zn) also it is realized in express train-analyzer LIES. Also the special attention is given by the authors to an estimation of opportunities of the modern analytical devices realizing methods described above of the analysis.

In work it is emphasized, that laboratory analytical methods are irreplaceable for the control of nitrogen ammonium and nitrate, chlorides, mobile forms of phosphorus and potassium, many heavy metals and benzpyrene.

Also the authors present results of numerous natural researches of a soil cover, and also ground and ground adjournment which recently test on itself influence of the industry and motor transport more and more.

It is also noted that now, irrespective of growing interest to protection and preservation of ground, which promoted acceptance of some laws and regulations aimed at the complex decision of problems of ecologically safe wildlife management, has ripened necessity of updating of the list of the substances which are a subject to the obligatory control in territory of large cities and the industrial centers. The following is offered additionally authors by the authors: mineral oil; the substances, which are AGM (antiglaze materials) compounds: Ca; Mg, etc. also results of researches of soil tests of Moscow for 2006-2007 on the listed components are presented.
