Organotins, especially tributyltins (TBT) are highly toxic to many marine organisms. These compounds are introduced in marine waters by ship trafficking, ship scrapping activities, as antifouling compounds and sewage disposal. Marine fishes, crustaceans and molluscans are easily prone to organotins contamination. In view of this, a baseline monitoring study was conducted in order to establish t...

Organotins present a toxicological risk to biota in the aquatic environment. Understanding the behaviour of these compounds in sediment is challenging, with sophisticated analytical techniques required for their measurement. We investigated the use of silica-bound sorbents for diffusive gradients in thin-films (DGT) adsorption gels to pre-concentrate five organotins (monobutlytin (MBT), dibutyl...

BACKGROUND Because of the vital importance of the proteasome pathway, chemicals affecting proteasome activity could disrupt essential cellular processes. Although the toxicity of organotins to both invertebrates and vertebrates is well known, the essential cellular target of organotins has not been well identified. We hypothesize that the proteasome is a molecular target of environmental toxic ...

Organotins have been used most extensively as the main biocide in antifouling paints. Due to deleterious effects, the use of organotins on small boats has been widely prohibited since the mid-1980s. IMO’s Antifouling System Convention entered into force on 17 Sept. 2008 [1]. As a result, other formulations have been used. The goal of this study is to assess the level of antifoulants in ports an...

Organotin compounds result from the addition of organic moieties to inorganic tin.Thus, one or more tin-carbon bonds exist in each organotin molecule. The organo-tin compounds are ubiquitous in the environment. Organotin compounds have many uses, including those as fungicides and stabilizers in plastics, among others in industry. The widespread use of organotins as antifouling agents in boat pa...

Organotins have been widely used as agricultural pesticides, anti­ fungal agents, polyvinyl chloride stabilizers, industrial catalysts, and antifouling additives in boat paints. These tin­based chemicals, which have been detected in various environmental media, are lipophilic and thus capable of becoming increasingly concentrated as they pass up the food chain. A new study suggests that the tox...
