Toxic Effects of an Anionic Detergent -Linear Sodium Alkyl Benzene Sulfonate on Oxygen Consumption and Gill Structure of Anabas Testudineus

Abstract

Detergent toxicity studies are crucial for environmental risk assessment and hazard classification. Linear alkyl benzene sulfonate is a widely used anionic surfactant in domestic cleaning products such as laundry detergent and dish liquid. It is also widely used in textile and personal care industries. Its presence alters the quality of water primarily by reducing dissolved oxygen and adversely affects the existence of aquatic organisms. The present study analysed the effect of various concentrations of linear alkyl benzene sulfonate on oxygen consumption of Anabas testudineus and further changes induced on gill surface as a consequence to exposure. Continuous exposure to sub-lethal concentration of alkyl benzene sulfonate caused alterations in behavior responses of the fish and reduced the amount of dissolved oxygen in water. It also decreased the rate of oxygen consumption of the fish and caused damages to the gill surface. By conducting toxicological studies on detergents, researchers can provide critical insights into the potential risks and impacts of these widely used chemicals, ultimately informing strategies for safer use, disposal, and regulation.
