Dredging of the harbour to remove Tributyl Tin
(TBT) contaminated sediment.
Since the ban on the use of tributyl tin
as an antifoulant active in marine coatings, the combination of cuprous oxide and a co-biocide (algaecide) has been the system of choice.
According to the obtained results, the catalyst resulted from tributyl tin
chloride would exhibit greater catalytic behavior than that of prepared from tin chloride.
The convention was adopted by the IMO in October 2001 and bans the use of anti-fouling paints containing harmful organotins, such as organotin tributyl tin
(TBT), on ships and requires parties to ensure that proper disposal of wastes containing anti-fouling compounds.
Not only is overall coatings production expected to rebound from a poor performance in 2008, but organosulfurs are likely to be the leading replacement for tributyl tin
(TBT) in the marine antifoulant segment.
1) Coatings containing toxic materials such as tributyl tin
and cuprous oxide have been used for decades as effective antifouling coatings.
8 million trees annually) and water for irrigation, and many nappies also contain TBT, or tributyl tin
, a pollutant that disrupts the immune and hormonal systems of shellfish.
One of these proposals involves tributyl tin
(TBT), which is used in anti-fouling paints for ship hulls and is toxic to fish, molluscs and other organisms.
New laboratory experiments indicate that one contributor to coral decline may be the paint additive tributyl tin
Some disposable nappies even contain the chemical Tributyl tin
(TBT), used in boat anti- foulingpaint.
Concentrations of DDT, other organochlorine pesticides, tributyl tin
, and PCB's continued to decline throughout the Bight during the 1990's, following major rapid decreases that occurred between 1965 and 1985.
Organosulfurs will experience gains in the marine coating market, boosted by the environmentally driven shift away from tributyl tin
, which will be banned by the International Maritime Organization as of 2003.
