TBT is commonly introduced into coatings as tributyltin oxide, tributyltin fluoride, or as a part of an acrylic copolymer that has hydrolyzable tributyltin side chains. All three mechanisms are used to make effective antifouling coatings.

Many other organotins (triphenyltin, tributyltin acetate, tributyltin fluoride, and others) have also been. Additional Physical Format: Online version: Tributyltin oxide.

Geneva: World Health Organization, (OCoLC) Material Type: Government publication. Tributyltin oxide, or, more formally, bis(tributyltin) oxide, is a rather nasty substance and a potent biocide.

Like most volatile organotin compounds, it can cause ill effects ranging from skin irritation to convulsions. Its main use is as a wood preservative. Tributyltin oxide is extremely hazardous to some aquatic organisms at very low concentrations.

As a result, government restrictions have decreased the global use of tributyltin compounds in antifouling paints on small boats. The compound has been detected in water, sediment, and biota in areas close to pleasure boating activity, in treated.

Physical Properties: Value: Reference: Molecular Weight (g/mol) TR: Solubility @ degC (mg/L) TR: Vapor pressure @ degC (mmHG) e The excretion route of tributyltin is mainly the bile rather than the urine. An initial rapid elimination of tributyltin oxide injected intraperitoneally to mice has been shown with a slow phase in the feces (Brown et al., ).

Thus, approximately 90–96% of ingested tributyltin.

Tributyltin (TBT) is an umbrella term for a class of organotin compounds which contain the (C 4 H 9) 3 Sn group, with a prominent example being tributyltin oxide. For 40 years TBT was used as a biocide in anti-fouling paint, commonly known as bottom paint, applied to the hulls of ocean going paint improves ship performance and durability as it reduces the rate of biofouling (the.

Tributyltin was mainly found in areas of heavy boating or shipping traffic, which was consistent with its use as an antifouling agent.

In 8% of the locations across Canada at which samples were collected, TBT was found in water at concentrations that could cause chronic toxicity in a Cited by: 2.

The main goal of this study was to assess the potential of the mouse thymoma EL-4 cell line in screening for chemical induced immunotoxicity. Therefore, EL-4 cells were exposed to two well-known immunotoxicants, organotin compound tributyltin oxide (TBTO, and 1 μM for 3 or 6 h) and the mycotoxin deoxynivalenol (DON,and 1 μM for 3, 6 or 11 h).Cited by: 3.
