IMPACTOS AMBIENTAIS DO ALQUIL BENZENO SULFONADO LINEAR/ENVIRONMENTAL IMPACTS OF LINEAR ALKYL BENZENE SULFONATE

The use of surfactants has grown around the planet exponential levels and linear alkyl benzene sulfonate (LAS) is the most used anionic surfactant across the globe with an annual production of 2.8 million tons. Because of this growing concern about the adverse effects that the improper disposal of this substance leads to the terrestrial and aquatic environment. The harmful action, the surfactant LAS, the life of the biota of these environments occur mainly due to disruption of the cell membrane through interaction with lipid components, and reaction with enzymes essential to the functioning of cells, these effects enhanced by its concentration. Concentrations below 0.29 mg / L reduce its harmful effects and the treatment of this anionic surfactants a strategic factor for increasing the water supply and the conservation of natural resources in the region.
