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...

In this study, the results of application advanced oxidative processes to remove linear alkylbenzene sulfonate (LAS) from wastewater produced in laundry industry are presented. Photocatalysis with UV radiation and oxygen peroxide (H2O2) was applied followed by ozonation (O3). LAS removal higher than 90% first 60 min. H2O2 based on COD reached its most effective concentration for rate [1:2.5] O3...
