Technological processes that are applied at civil engineering and metallurgic enterprises involve intense emissions of solid particles into ambient air. Adverse impacts exerted by particulate matter on human health have been confirmed by multiple research works, both domestic and foreign ones. At the same time, an extent to which technogenic dust emissions are hazardous is determined by contents of various chemical components in them including heavy metals. The research goal was to quantitatively and qualitatively...

The Azov Sea is one of the shallowest inland reservoirs in Eurasia. The special physical and geographical location of that object determines the temporal variation of its hydrological and hydrochemical characteristics. One of the main features of the sea is the presence of run-off and surging phenomena, determined by water exchange with the Black Sea and the river flow, small area and shallow water body. The currents are considered as significant factors for many processes of matter and energy transport in the Azo...

Majority of world inhabitants are living in cities as well as many inhabitants in Latvia choose to move to cities to look for wellfare. Living in a city with a high density of buildings, cars, and factories, the risk of air pollution increases. Air pollution from the transport, industry, and energy sectors affect the health of the urban population. In cities, air is often contaminated with dust containing various chemical elements, including heavy metals, which, even in low concentrations, can be hazardous to huma...

The paper focused on the formation mechanisms of the geochemical soil background for a wide range of elements. Three areas in Siberia of the coal mining spoils were investigated. The spoils were recultivated 30 years ago by applying a homogenous layer of loamy bedrock as a potentially fertile substrate and then left for spontaneous revegetation. The assessment was conducted using bulk concentrations of the elements. Since there is no excess in concentrations of heavy metals and radionuclides in the recultivated sp...

The world modernization, global development, maximum utilization of minerals and ruthless treatment of the environment by humans have created many environmental problems around the world, and Georgia is no exception. One of the richest deposits in Georgia are in Bolnisi, where the RMG (formerly Madneuli) mine is functioning, located in Kazreti, on the right bank of the Mashavera River. Open-pit mining processes causes soil and water contamination, which do harms to human health and ecosystem. Remediation projects ...

The long-term activity of a polymetallic ore mine in the region of Tarnita-Suceava, Romania, has resulted in an enormous amount of waste material, collected in tailing dumps and ponds. The impact of the waste materials on the surrounding ecosystem and human health are far to be fully estimated. The deposited waste has exerted negative impact on the environment, especially on the soils that host dumps and drainage waters. Heavy metals, including arsenic also interfere with the metabolism of plants, and reduce the n...

Cleaning contaminated soil from heavy metals is a very important issue for Ukraine at present. Soil pollution is considered to be the result of metallurgical and chemical industries, as well as the irrational application of chemical plant protection. The goal of the studies was investigation of effectiveness of phytoremediation with co-cultivation of herbaceous plants as one of decontamination methods. An innovative method of cleaning soil from heavy metal contamination using a combination of switchgrass and peren...

The article presents an assessment of changes in chernozem soils of agricultural land as a result of anthropogenic impacts. It is shown that the agricultural soil utilization leads to significant disturbances in the ecological balance and is accompanied by an increase in the disequilibrium of the state of the systems, an increase in the degradation risk, which becomes excessive with improper use of soils and the wrong choice of farming systems. In order to prevent negative developments associated with agricultural...
