Title : Distribution of heavy metals in soils located along the highways of Georgia (along the West-East section)
Abstract:
In connection with the study and fixation of Georgia's pollution with heavy metals, specialized geochemical studies were carried out regarding highways. The purpose of the study was to establish and identify soil pollution halos along the highways from the Western parts of Georgia (Black Sea) to the Western regions of the country.
The study and analysis of soils from different regions of Georgia revealed interesting results that still require further explanation from the point of view of identifying sources of pollution.
An example is the content of copper in soils. Their presence along the roads changes dramatically from West to East. If near the Black Sea coast their content sharply exceeds the limits of what is permitted (sometimes exceeding the norm by 10 or even 17 times), then moving east, already in Imereti and further, it is placed within the normal range. Pb in the soil is present everywhere within acceptable limits, and only in one region - in central Georgia, it exceeds the norm by 2-3 times. Zinc reveals a rather unstable state in different regions of Georgia, sometimes staying near the norm, sometimes exceeding it several times. The latter emerges especially clearly in the eastern part of the country, east of the city of Tbilisi. In all regions of Georgia, the nickel content is in the range of 40-100 mg/kg. However, the content of cadmium often reaches 10 mg/kg, which is alarming. It is necessary to pay attention to the content of As, which in western Georgia exceeds the permissible values several times. However, the presence of this element in the soils of Western Georgia (in the Racha region) is quite understandable in connection with the discovery of deposits of this chemical element. We can state approximately the same with the amount of manganese in soils. After all, it is known that in the region of Imereti there are large deposits of manganese, which leave their traces throughout Western Georgia (up to the Black Sea), and therefore their content in soils sometimes exceeds the permissible norms by 2-10 times.
All these revealed values force us and other researchers to specialize more carefully and study specifically individual anomalous areolas of Georgia.
Audience Take Away:
- It will be learn from us specific data on the presence of heavy metals in the soils of Georgia, which were not known at this time;
- We hope for joint projects with the study of regional problems;
- It will be necessary to jointly search for the causes of the abnormal distribution of heavy metals in soils;
