Soil surface pollution with heavy metals caused by coal-fired boilers

Abstract

One of the goals for environmental experts is to help avoid, prevent or reduce harmful effects on human health and the environment as a whole. The idea is that the public and the polluting companies would be informed of the effects of pollutants on humans, flora and fauna. To realize this goal are carrying out environmental monitoring, investigations and analysed the results. The aim of this work is to evaluate JSC „Nemencines komunalininkas“ boilerNo. 9 resulting air pollution. Company is located in Vilnius region. The focus is on longterm emissions, e.g. heavy metals (HM), the accumulation on the soil surface to examine boilerNo. 9 impact on the area and assessing the longterm impact on ambient air quality. Soil samples was taken by the principle of the envelope in 11 selected locations 50–300 meters around the boiler area, using noncolour, nongrease, stainless steel tools. Examination of heavy metals in the soil solution, to get the actual data on the amount of HM and their distribution in the soil around the coal fired boiler territory. Pollutants into the environment, exposure depends on many physical and geochemical processes. Environmental pollutants distribution describes not only the various environmental processes, physical and chemical properties of materials but also the weather conditions. Carryover assessed the prevailing wind direction, as well as simulated through forecast of the largest concentrations of locations. To assess of the boiler No. 9 environmental impact of selected air pollutants was choose in longterm storage medium (soil).
