heavy metals

Based on the findings it can be argued that if the possibility of man-made pollution of atmosphere-reflex to avoid cultivation of home gardens leafy vegetables such kapus-you. Among nadhruntovyh vegetables differen-tiation observed metal-accumulative properties of plants according to their physiological characteristics. Based on comparison of the biological absorption of metals by plants containing their mobile forms in the soil can be determined that the increase in the content of heavy metals in the soil in plants include mechanisms regulating the selective absorption of micronutrients, which are determined by genetic characteristics of plants. The ecolog-ical status of the natural components of the environment is a dominant factor in determining the quality of the food.

The questions about the role of the aquatic ecosystems biological component in the formation of sediment were reviewed. The role of aquatic organisms (phytoplankton, higher aquatic plants, invertebrates, and other groups of organisms) in self-purification of aquatic ecosystems and the formation of sediments were analyzed.

The spatial distribution of heavy metals in abiotic components of aquatic ekosystems rivers depends pri-marily on landscape (natural) features of the area which is formed by runoff. Determining for the rivers and their areas under human influence becomes surface runoff from urban areas, wastewater and recycled water intake with feeding groundwater.The basic factors that influence the formation of the quality of the sediments in the river Seversky Donets and the accumulation of heavy metals were reviewed. Determined that a higher content of metals in the sediments have an average with a high content of silt and clay, which can be explained both by the chemical composition of the clay soil, and the ability to absorb himself in the metal from the aqueous phase.

As a result of the conducted researches necrosis of leaves and pine-needle of trees is exposed in central part of Kremenchug city. The accumulation of lead, iron, copper in the leaves of arboreal breeds has been investigated. Possibility of use the results of research data in planting of greenery of cities is examined for the bioscrubbing of environment.

The conditions for the formation of sediments, depending on the nature of singularities. Identified sources of heavy metals into the «water environment - bottom sediments of the», greatest impact erosion of the catchment area of the rivers. It is confirmed that the sediments are the main hubs of mass of pollutants, including nutrients and heavy metals, due to entering the water bodies of significant volumes of solids due to soil erosion from the catchment basin.

The methodological procedure of comprehensive evaluation of soils of farms in Kremenchugskiy, Semenivskiy and Hlobynskyy districts of Poltava region is substantiated in the work. The analysis of geological and geomorphological, climatic, landscape-geochemical conditions have been carried out in the districts by analyzing groups of factors, as: natural, geochemical and anthropogenic pressures.

Reasons of environment pollution by waste motor oils (WMO) and aspects of environmental safety of WMO are considered. The volume of WMO generation by vehicles is calculated for Kharkiv Oblast (year 2013). Economic losses for environment pollution caused by illegal WMO utilization are calculated. Based on experimental researches, ash and sulphur contents were measured. Comparison of obtained data with M40 masut parameters has shown that WMO ash and sulphur contents are higher than the same parameters for masut. In ash from M100 masut ten heavy metals were identified; concentration of all metals (except Cu) is WMO ash was higher than their concentration in M100 masut ash. It is shown that WMO can be utilized through burning only in case of implementation of set of protective measures.

There has been investigated the soils buried under the body of the shaft of the early iron age and modern (background).There has also been carried out comparing them to assess the environmental condition of the landscape with in which the profiles of soil are situated. It has been defined that soil formation processes that underpinned the modern profiles and buried (ancient) soil, are characterized by a combination of processes of capable of the accumulation of substances, radionuclides and heavy metals. It has been determined that the amount of heavy metals lies within background values. The obtained data testify the fact that in the modern (background) soil the heavy metals are being accumulated in arable horizon. It has been fixed that in the modern soil the concentration of heavy metals in profile is a higher than in buried one. This shows the change of conditions and factors that affect geochemistry of the landscape for a long time of their formation
