Evaluation of the quality of environmental factors, soil and water in the Parang Mountains, Romania

Abstract

This paper aims to assess the quality of environmental factors, soil and water in the Parang Mountains (Meridional Carpathians). To determine the degree of soil pollution areas: Baile Olanesti, Calimanesti-Caciulata, Voineasa, Obarsia Lotrului, Transalpina and Baile Govora, were sampled on two levels deep. To characterize the surface water samples were taken from rivers: Olanesti, Olt, Lotru, Hinta and Govora. In soil samples analyzed, it was found generally insignificant soil pollution with heavy metals (nickel, copper, cadmium, lead, zinc, chromium) and sulfates. There was a significant potential pollution with Total petroleum hydrocarbons (downstream the city Olanesti, 4 km upstream the city Caciulata) and a significant pollution with Total petroleum hydrocarbons (upstream the city Baile Olanesti and 4 km downstream the locality Obarsia Lotrului). In water samples, ammonia had values between 0.1 and 0.63 mg / L, nitrates values between 0.03 - 2.42 mg / L, nitrites values between 0.03 to 2.48 mg / L, phosphorus values between 0.02 to 1.36 mg / L. Also, there was not found a load of inorganic chlorides, calcium, sodium and sulfates and organic load (COD), all indicators complying with the limits of classes 1st and 2nd of quality. Exception did Hinta and Govora creeks that due to the mineral springs in the area had a high inorganic loading.
