Abstraet--Surfactants are one of the major components (10-18%) of detergent and household cleaning products and are used in high volumes. Several are commonly found in natural waters and consequently, their impact on the environment has been, and continues to be, discussed in the U.S.A., Western Europe and Japan. The chronic and sublethal toxicities of commercially important surfactants to aqua...

Sewage sludge applied to agricultural soils often contains considerable amounts of linear alkylbenzene sulfonates (LAS). Toxic effects of LAS on soil organisms should, therefore. be evaluated to ensure safe use of sewage sludge as a fertilizer. In this study, dose-response relationships for the toxicity of Na-LAS to six species of soil invertebrates (survival, reproduction, and growth) were est...

The increasing number of laundry businesses in Pontianak causes increased waste, which is dangerous for health and the environment because anionic surfactants such as Linear Alkylbenzene Sulfonate (LAS) are hard degradable. Photocatalyst a method that can be used to degrade LAS structure. TiO2 carried coconut fiber optimize sunlight irradiation degrading content when light reaches water's surfa...

Mosquito fish (Gambusia affinis) is a species often used as bioindicator because it has high adaptability to water quality changes. Linear alkylbenzene sulfonate (LAS) surfactant found in waters and can cause death for the biota that lives it. This study aimed analyze impact of LAS on survival mosquito determine minimum concentration tissue damage. Research conducted during April 2022 using 500...
