Assessment of pollution with organochlorine substances in the accumulation lakes on the Olt River, using the fugacity model

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 -trichlorobenzenepollutants in biota as environmental component in amounts
which may generate medium to long term by taking over risks to human health.
