THE CURRENT STUDY REGARDING AIR POLLUTION WITH SETTLED POWDERS IN THE INFLUENCE AREA OF MINING EXPLOITATION ROȘIUȚA FROM COUNTY GORJ
Journal Title: Annals. Food Science and Technology - Year 2016, Vol 17, Issue 1
Abstract
In county Gorj the mining industry is represented by the surface mines which contribute significantly to the economical development of the area. Surface mining exploits are polluting the environmental factors through the industrial activities that take place, as well as through the huge quantities of waste that are produced. The Roșiuța surface mining exploitation site is located in the south-west of county Gorj. In this study will be presented the current research about the air pollution in the influence area of the surface mining exploitation Roșiuța form county Gorj. The most significant sources of atmosphere pollution in the area of the Roșiuța Quarry are dumping excavators, the conveyors, the distribution nods, the coal deposit, the waste dump and the access routes. For the monitoring of the settled powders eight sampling points were established from which seven were placed in the influence area of the coal deposit. The determination of the settled powders content has been conducted accordingly to the 10195/75 standard. The air purity, determination of the settled powders. The results obtained after the measurements conducted regarding the settled powders during the years of studies 2013-2014 have shown that during the year 2014 the frequency of allowed limit exceeding (53.3% )was higher than in 2013 (47.3%). The lower values were obtained during the winter season and this is explained by an interruption of the excavating, transport and storage activities for a period of time. The large concentrations of settled powders during the summer-autumn seasons, represented by the huge number of exceedings, can be caused by the meteorological conditions in this seasons, when there is less rainfall and the economical agent doesn’t apply the necessary measures to reduce the powders emissions in such situations.
