In this study, structural changes of liver and gills the crucian carp after one-month exposure to different concentrations alkylbenzene sulfonate (AS) surfactants were evaluated by pathological sections organs. The results indicated that effect AS on was mainly reflected in nucleus swelling, cell membrane rupture, blurring boundaries, appearance vacuoles cytoplasm. Meanwhile, occurs gill filame...

in this paper the photocatalytic degradation of the anionic surfactant, linear alkylbenzene sulfonicacid (labsa) was investigated using uv radiation in the presence of tio2. our findingsdemonstrate that various parameters exert their individual influence on the photocatalytic degradationof surfactant in wastewaters. the mentioned parameters have been categorized as follow: the initialph of the ...

Aromatic sulfonates (R-SO(3)(-)) can be used as sulfur sources by sulfate-starved bacteria in laboratory cultures and the corresponding phenols are excreted from the cells. The present study was conducted to demonstrate whether such desulfonation reactions also occur in sulfate-leached agricultural soil, where desulfonation of organic sulfur compounds may have agronomic importance as a S source...
