Interaction of triorganotin compounds with chesapeake bay sediments and benthos

Abstract

Triorganotin compounds can interact with various segments of natural water systems. In sediments, for example, these compounds can undergo speciation, and can also become injurious to benthos. The interactions of tributyltin (TBT) and triphenyltin (TPT) compounds with sediments have been studied using extraction techniques in addition to directly observing these compounds in sediments using Mossbauer spectroscopy. The effect of these compounds on benthos has also been examined. The results of these studies are reviewed with particular regard to studies on sediments from the Chesapeake Bay, USA.

Tributyltin and triphenyltin uptake by lettuce

“…However, the question about the mechanisms of transport inside the plant remains open for discussion, mainly considering the physico-chemical properties of these species. The passive transport of OTCs by simple diffusion through the lipid bilayer membrane has to be taken into consideration because these compounds are lipophilic, non-polar, and usually widely absorbed by the lipidic fractions of living organisms (May et al, 1993;Fent, 1996;Rü del, 2003;Phinney and Bruland, 1994). Transport of the lipophilic species has slow kinetics, which could explain why OTC amounts in shoots increased with time but remained low (Laberche, 1999;Adriano, 2001).…”

“…The detrimental effects of TBT and TPT upon non-target organisms led to restrictions to the use, first in France in 1982, where antifouling paintings containing TBT were prohibited for boats of less than 25m length (Sarradin et al, 1991;Waite et al, 1991), and then in many other countries, such as the United Kingdom (1987), United States (1988), Sweden, New Zealand (1989), Australia, Japan (1990) and Denmark (1991) (Champ & Pugh, 1987;de Mora et al, 1989;Horiguchi et al, 1994;Kure & Depledge, 1994;May et al, 1993;Stewart & de Mora, 1990;Stuer-Lauridsen & Dahl, 1995). Germany and Switzerland imposed restrictions also for freshwater environments (Champ, 1986 (Champ, 1999;.…”
