ABSTRACT
Romania is a country with tradition in oil and gas industry, being registered, for a long time, among world’s producers and exporters of oil and oil equipment. Petroleum or crude oil is a major natural riches of our country. Large deposits of oil are found in counties: Argeș, Bacău, Bihor, Brăila, Buzău, Prahova, Gorj. The oil was little known and used in ancient times, compared to other natural resources, such as gold or salt. It’s exploitation in Romania at industrial level, started in 1857 with the construction of the first distillation at Râşnov from the Prahova County, with an annual production capacity of 2700 To of kerosene; in the first year there were processed about 295 tons of oil. In those 160 years, the production of fuels was continuously developed and perfected, unfortunately often at the expense of biotic and / or abiotic environment protection. In case of accidental pollution, when oil is spilled on the ground, it percolates the vadose area, reaching the saturated area, where it disperses in the first aquifer. Once the pollutant reaches the soil, depending on the conditions found in soil (texture and structure), it takes one of three phases: gas, free state or dissolved phase. This study highlights the correlation between the phase in which the pollutant is found, the area with terrace sedimentary deposits from the Târnava Mare River, where it is stored or dispensed, and the risk determined by the toxicity of chemicals from the pollutant’s composition to human health and biotic environmental factors.
