Assessment of the Impact on Atmospheric Air Quality Due to Ignition of Illegal Landfills

Purpose. To assess the impact on the atmospheric air quality and to calculate environmental risks due to burning of illegal landfills. Methods. Field and laboratory methods and analytical data processing. Results. The research has shown that the main pollutants in the combustion of solid waste are nitrogen dioxin, carbon monoxide, sulfur dioxide, soot, and undifferentiated dust. At the point of emission of pollutants into the atmosphere, the maximum concentration limits of these substances significantly exceed the max allowable ones. In particular, the MAC of NO2 was exceeded in 45 times, CO – in 22 times, soot - in 210 times, SO2 – in 40.8 times, the MAC of undifferentiated dust was exceeded in 120 times. The results of pollutant emissions obtained empirically were significantly differ from those calculated by using the existing methodology. For undifferentiated dust, the results of field measurements exceed the calculated in 73.2 times, for sulfur dioxide – in 10.4 times, for nitrogen dioxide – in 3.5 times, for carbon monoxide - in 6.7 times, for soot - in in 76.8 times. The calculation of pollutant scattering using the EOL + program showed that the combustion of solid waste in a landfill on the border of residential area will exceed the maximum concentration limits for three substances. The calculation of risks for the population was performed. Conclusions. Risk calculations for the population has showed that the impact of carcinogenic and non-carcinogenic substances is minimal, i.e. acceptable. The overall risk over a lifetime is also minimal (acceptable). Unauthorized landfill, of course, must be removed with the subsequent restoration of damaged components of the environment.

Assessment of the Atmospheric Air Quality Within the Main Вus Stations Kharkiv

Purpose. The aim of the paper is determine of atmospheric air quality withim the main Bus Stations in Kharkiv. Methods. The following methods were used: filed, laboratory and statistical ones. Results. The results of the researches was found that the content of dust, carbon monoxide and nitrogen dioxide in the atmospheric air of the city of Kharkiv around Bus stations №1 " Avtovokzal", № 3 " Kinnyj Rynok", № 6 "Zavodska", and Kholodna Gora Terminal higher than MACs. The highest concentrations of pollutants were identified around Bus stations Nr 6 “Zavodska” and Kholodna Gora Terminal. It have shown a tendency to increase in atmospheric air concentrations of gasoline, carbon monoxide, nitrogen dioxide. The temporal tendency to increase in atmospheric air concentrations of gasoline, carbon monoxide, nitrogen dioxide was revealed. Conclusions. The detected excess of the MPC of harmful substances in the atmospheric air of the city of Kharkiv in the districts of the bus stations indicates a difficult situation with the quality of atmospheric air in the cities of intensive traffic, especially in the respiration zone of children. Recommendations aimed at improvement of air quality was proposed.

Humus Horizon Of Urban Soils As A Geochemical Barrier In Urban Landscape

The increase of humus to the emergence of techno and organosorbtion geochemical barrier in the surface lay-ers of urban soils, which contributes to the consolidation of heavy metals and increases the contrast anomalies. Total content of heavy metals in the surface layer of urban soils confirms deposit pollution geochemical barrier humus layer of the soil. The distribution of heavy metals in soil south-eastern city of Kharkiv indicates a certain level of contamination exceeding the industrial area of residential and sanitary protection for Zn and Pb. Land-scape-geochemical state of the city are promoting priority pollutants on the alkaline and biogeochemical barriers in soil and plants. It can be assumed that a mechanism of self-regulation urban landscape that manifests itself in enhanced feedback and confirmed the existence of the identified features of the urban soils.

Utilization of waste motor oils: environmental-and-economical aspect

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.
