The use of detergents has become widespread and is growing. The increase in population and use of detergent threatens the life of organisms in the ecosystem. In this study, the histological effects of linear alkyl benzene sulphonic acid on primordial germ cell (PGC) migration and gonad formation in zebrafish were investigated after application of 0.25 0.5 and 1 mg/L of linear alkyl benzene sulphonic acid to embryos. Samples of embryos and larvae were collected for 60 days and the effects of linear alkyl benzene sulphonic acid on PGC migration and gonad development were examined by histological procedures. The localization and migration pathway of PGCs and structures of the gonads were inspected by Periodic Acid Schiff (PAS), alkaline phosphatase, toluidine blue and Best?s carmine staining. Primordial germ cells were observed in ectopic regions and delayed gonadal development and histopathological changes in gonad structures were observed. We concluded that linear alkyl benzene sulfonic acid exposure has a negative effect on the reproduction system of zebrafish.

Solutions of tetramethyl tin trimethyl tin sulfate, di-n-butyl tin diacetate, tetraphenyl tin, and triphenyl tin hydroxide in. 100% sulfuric acid have been investigated by cryoscopic and conductimetric methods. Tetramethyl tin reacts with sulfuric acid with the evolution of methane and the formation of trimethyl tin hydrogensulfate. Trialkyl tin hydrogensulfates and dialkyl tin dihydrogensulfates behave as strong bases. It is probable that the cationic species formed are protonated hydrogensulfates rather than "stannonium" ions. Phenyl-substituted tin compounds are cleaved in sulfuric acid with the formation of benzene sulfonic acid and the complex hexa(hydrogensulfato) stannic acid, H2Sn(HSO4)6, and its anions. Lead tetraacetate gives yellow solutions containing hexa(hydrogensulfato) plumbic acid, H2PB(HSO4O6, and its anions.
