Assessment of Pollution with Organochlorine Substances in the Accumulation Lakes on the Olt River, Using the Fugacity Model

Abstract:

This aims of this paper is to studying the transfer of organochlorine substances (1, 2-dichloroethane, trichlorethylene, perchlorethylene, benzen and 1,2,4 -trichlorobenzene) in the environmental water, sediment and biota using calculation MacKay model. In order to study the transfer of organochlorine substances in the environmental compartments (water, sediment, biota), was chosen as the study area, the lakes of Zavideni (Z), Dragasani (D) and Strejesti (S) on the River Olt. In this study, sections studied are located downstream from the chemical platform Ramnicu Valcea. Zavideni section is located approx. 40 km to the paltform, Dragasani section situate approx. 20 km to the Zavideni section while the Strejesti section is located approx. 10 km to the Dragasani section. The utilization of this model has highlighted the transfer in the air as environmental component of the 1, 2 dichloroethane, trichlorethylene and benzene, are known in fact that the volatile compounds. However, based on the modelling, there is a significant transfer of the perchlorethylene and 1, 2, 4 -trichlorobenzene pollutants in biota as environmental component in amounts which may generate medium to long term by taking over risks to human health. Keywords: organochlorine substances, MacKay model, fugacity, environmental compartments
