Tin is a naturally occurring element. It is a silver-white, malleable, and somewhat ductile metal. The earth's crust contains about 2–3 ppm tin, comprising 0.0006% of the earth's crust. Major uses of tin include cans and containers, electrical, construction, and transportation. Industrially important tin compounds can be categorized as inorganic (those without a tin-carbon bond) and organic (th...
Organotin compounds have been found different application in industries, agricultures and pharmacological sciences via their various physical and biological specifications. One of the most important applications of these compounds, especially tributyltin TBT is in marine antifouling paints and coatings. Concern about the accumulation of tributyltin compounds on fish and shellfish and the advers...
the melt-phase synthesis of dioctyltin (iv) and triphenyltin (iv) benzoates were carried outusing stoichiometric amounts of benzoic acids and the corresponding organotin (iv) compounds.the reagents were ground together in a mortar and fed into a boiling glass tube. a cannula tubewas inserted into the boiling tube to discharge accumulated gaseous products. a syringe ensureda continuous flow of d...
The objective of this study was to measure the concentrations of organotin compounds in the whole blood of Finnish male fishermen (n=133), their wives (n=94), and other family members (n=73), and to investigate their associations with background variables. The concentrations were generally low, less than the limit of quantification (LOQ) for the vast majority of compounds and samples. Of the or...
Sediment samples were collected in the Gulf of Gdańsk, and the Vistula and Szczecin Lagoons-all located in the coastal zone of the Southern Baltic Sea-just after the total ban on using harmful organotins in antifouling paints on ships came into force, to assess their butyltin and phenyltin contamination extent. Altogether, 26 sampling stations were chosen to account for different potential expo...
Organotin compounds such as triphenyltin (TPT) and tributyltin (TBT) act as endocrine disruptors through the peroxisome proliferator-activated receptor γ (PPARγ) signaling pathway. We recently found that TPT is a particularly strong agonist of PPARγ. To elucidate the mechanism underlying organotin-dependent PPARγ activation, we here analyzed the interactions of PPARγ ligand-binding domain (LBD)...
