Based on the analysis of statistical yearbooks "state of contamination of soils and objects of the natural environment of the Russian Federation with pesticides and toxicants of industrial origin", analysis of the incidence of workers and the population from exposure to residual pesticides and heavy metals, the need to assess soil contamination for organic farming purposes in accordance with the requirements of article 9 of the Federal law of 03.08.2018 No. 280-FZ "on organic products and amendments to certain legislative acts of the Russian Federation"is justified. For evaluation, a digital technology is proposed in the management of environmental safety and labor protection in agriculture, developed by scientists of the ITOSH-branch of the FGBNU FNAC VIM. It is proposed to solve the problems of detoxification of soils contaminated with heavy metals and residual pesticides identified during the assessment using the available domestic and foreign experience by various methods: physical, physical-chemical, and biological.

Contamination Of Soils

As a result of accidental spills or leaks, industrial wastes may enter in soil and in streams. Some of the contaminants may not be completely removed by treatment processes; therefore, they could become a problem for these sources. The use of synthetic products (e.g. pesticides, paints, batteries, industrial waste, and land application of industrial or domestic sludge) can result in heavy metal contamination of soils.

Heavy metals are one of the major pollutants. The main sources of pollution are industry, transport, the use of pesticides and mineral fertilizers in agriculture, the military industry, etc. Pollution is mostly around businesses, highways and treated terrains and they are polymetallic, mostly from Cu, Pb, Zn, Cd, Hg, As and others. In the current paper the main heavy metals for Bulgaria for the different sources of pollution are presented. An analysis of data for problem areas is made, according to sources of pollution. An analysis of the impact of pollutants on the environment is also conducted.

Contamination Of Soils

A significant degree of ploughness of agricultural lands of Ukraine has led to increased erosion and the creation of soils of varying degrees of washout, which leads to dehumification and contamination of soils with toxic substances. Therefore, the purpose of the study was to establish the features of horizontal migration and accumulation of heavy metals of lead, cadmium, copper, and zinc, trace elements of boron and manganese, radionuclides of caesium and strontium on podzolic heavy loamy chernozems with varying degrees of washout: non-eroded, weak and medium washout, conditioned by the development of erosion processes. During the study, spectrophotometric, colorimetric, gamma-spectrometric, and radiochemical methods were used to determine the content of toxic substances in the soil. The study results showed that on slightly washed soils, the content of humus is 12.9% less, easily hydrolysed nitrogen – 13.3%, mobile forms of phosphorus – 51.1%, mobile potassium – 34.9% less than on slightly washed soils. The humus content on medium-washed soil was 8.8% less than on lightly washed soil, easily hydrolysed nitrogen – 14.3% less, mobile phosphorus – 15.3% more, mobile potassium – 42.9% more. A strong horizontal migration of mobile lead forms in washed podzolic heavy loamy chernozem was established, which increases with increasing degree of soil washout with the content of mobile lead forms on medium-washed soil by 24% more than on non-eroded soil. The same dependence was established on the content of mobile forms of zinc in the soil, with their predominance on medium-washed soil by 17 %, compared to non-washed. The content of mobile forms of copper is lower on slightly washed soil, compared to non – washed soil by 5%, boron – 18.8% less on non-washed soil, compared to medium-washed, and the content of mobile forms of manganese increases by 3.3% from slightly to medium-washed soil. It was also found that the concentration of caesium decreased by 25.6% on medium-washed soils, compared to non-washed ones

Contamination Of Soils

This article deals with the contamination of soils by oil products, chloride ions and heavy metals in the territory of the asphalt plant. The analysis of soil samples for the content of heavy metals was carried out by gravimetric and fluorometric methods. The soil is able to absorb technogenic impurities and also accumulate contaminants, including heavy metals, which, if excess, exhibit toxic properties, slowly breaking down under natural conditions and entering the cycle of trophic chains. The analysis of the selected soil sample was carried out in the laboratory of environmental monitoring of physico-chemical pollution of the environment in Birsk, Republic of Bashkortostan. Research shows there is an excess in majority of the investigated parameters are observed in the territory of the asphalt plant. The totality of the results of the soil state study in the area adjacent to the asphalt plant revealed a considerable level of soil contamination corresponding to significant degree of technogenic depletion. In its turn it speaks of the operation of technological equipment and a long working life.
