ABSTRACT

 

This aims of this paper is to studying the transfer of organochlorine substances (1, 2-dichloroethane, trichlorethylene, perchlorethylene and 1,2,4-trichlorobenzene) in the environmental water, sediment and biota using calculation MacKay model. The water/sediment samples were collected from the Olt River, in two locations, Cremenari and Babeni Marcea, situated downstream of the industrial platform Ramnicu Valcea, during 2013-2014. Modelling revealed clear trend the transfer of component "air" of these pollutants are known fact that volatile compounds, however, based on modelling was observed a significant transfer of these pollutants in the factor "biota" in amounts which may generate medium and long term risk to human health by taking in the food chain, which at first sight and a first risk assessment made by these pollutants for local residents can go unnoticed.
