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...

12 strains o f the geni Chlorella, Scenedesmus, Chlamydomonas, and Dunaliella were tested for their tolerance against the anionic detergent “L A S” (linear alkylbenzene sulfonate). Cellular parameters (cell titer and chlorophyll content) were monitored for 28 days after addition o f LAS (0 .0 1 —2 m M ) . A 100-fold difference in sensitivity toward LAS was detected for the algal strains analyze...

This study reports on the fate of linear alkylbenzene sulfonate (LAS), alcohol ethoxylate (AE), and alcohol ether sulfate (AES) surfactants in a home septic system near Jacksonville (FL, USA) that has been used since 1976. The drainfield at this site resides in fine sand (< 6% silt and clay) with an unsaturated zone that ranges from 0 to 1.3 m. During the wettest times of the year, it is likely...

Semakin banyak jenis limbah yang masuk dalam perairan mengakibatkan pencemaran. Pencemaran lingkungan berasal dari senyawa organik dan anorganik, sehingga perlu dilakukan pengolahan air limbah. Salah satu cara untuk mengatasi pencemaran terdapat di dengan teknik fitoremediasi. Tujuan penelitian ini mengetahui konsentrasi LAS pada tercemar agen fitoremidiasi tanaman jeruju (Acanthus ilicifolius)...
