Toxic Effect Of Surfactants On Marine Species ‎mediterranean Mussel: Mytilus Gallprovinciallis And ‎evaluation Of Their Aquatic Toxicology Impact By Lca ‎methodology

Authors : Belkhir‎ M . Boughrara S . Boutiche H .

Abstract

The increase of over 500% in ten years, the use of synthetic detergents ‎explains the high concentrations explain the high concentrations in liquid ‎effluents. Part of these discharges flow without purification in rivers. Which ‎it is interesting to assess the impacts thus generated by such a detergent ‎manufacturing process. In our study we used the tool life cycle assessment ‎‎(LCA) methodology to assess the aquatic toxicology impact of liquid ‎detergent intended multi user. This study needs the use of SimaPro7.1 ‎software and EDIP 2003method.In order to explain aquatic toxicology ‎impact was chosen by selecting a type of marine species Mediterranean ‎mussel Mytilus gallprovinciallis.In our study we determined the toxic effect ‎of anionic surfactants (LAS, AES) characterization of liquid effluents ‎generated by one of the leading Algerian companies in detergents. ‎Comparing the toxicology of two anionic surfactants is obtained after ‎determining the lethal concentrations of fifty percent (LC50) of the ‎individuated simmering with forty-eight hours (48h), Ensuring living ‎conditions (temperature, O2, pH, TH, TA, TAC). In an aquarium. Any and ‎controlling various pollution parameters (BOD5, COD, Nitrate, Nitrite, ‎Phosphate, Sulfate, Dissolved Oxygen. ‎
