TBT on the Way Out Measures in force since 1990 to reduce the amount of tributyltin (TBT), used in anti-fouling paints, are proving successful. In 1990 the Marine Environment Protection Committee of the International Maritime Organization adopted a resolution to control T B T use as it is known to damage marine organisms even at low levels. It recommended that all governments should work to eliminate the use of T B T through restrictions on the type of vessels able to use such paints; the careful monitoring of the way T B T can enter the sea via sandblasting and paint removal; the encouragement of alternatives to T B T and the monitoring of the success of the measures taken. A report by the European Council of Chemical Manufacturers' Association (CEF1C) states that in all regions surveyed T B T in water and in marine organisms has been reduced. Japan, which has monitored T B T levels since 1985 has noted reductions since 1989 and especially in 1992. The River Crouch in Britain has been shown to contain oysters which contained, in 1992, only one-tenth the level of T B T found in 1986. Ports such as Rotterdam, Genoa, Milford Haven and Bremerhaven also showed reduced levels and tests in the US east and west coasts, where the Organotin Antifouling Paint Control Act came into force in 1985, have found considerable reduction in the Gulf of Mexico and the Great Lakes. Marinas have shown reductions and the only areas where high levels are still found are in some harbours and in the vicinity of some shipyards and docks. In view of the success of the measures, the International Maritime Organization (IMO) has proposed a ban on the use of T B T paints on ships of 50 m or less and on ships which carry out most of their work in coastal waters. They have also recommended the development of sound dockyard practices and more encouragement given by governments to alternatives to T B T paints.
Liability Accepted for South African Oil Spill Oil which has been polluting South Africa's Cape coast tourist beaches has now been stated to have leaked from a Chinese-controlled bulk carrier, the Apollo Sea. The vessel's owner and protection and indemnity insurers have admitted the liability in spite of the fact that only circumstantial evidence appeared to link the ship to the oil. The 131 250 dwt Apollo Sea, carrying iron ore disappeared in June after a distress call and it was presumed lost with all its 36 crew members. Two underwater surveys of a wreck have convinced the Panama-based ship owning company of the Cosco Guangzhou vessel that it is the Apollo Sea and that the link with the oil of the Cape's beaches is very likely. An estimated 2400 t of intermediate fuel oil and 150 t of
diesel oil went down with the ship. The wreck is no longer leaking oil. Most of the oil has been cleaned off the tourist beaches and the manual cleaning of rocks is underway. Fire hoses and other types of pressure hoses have also been tested. The protection and indemnity insurers, The West of England Club, provided S500m pollution cover to the ship. They have agreed to meet all valid claims for the cost of clean-up as long as they were subject to the relevant legal provisions and submitted via the Department of Environmental Affairs as specified by the Cape zone coastal oil contingency plan. The acceptance of liability followed statements from the South African Department of Transport that they would take legal action against the owners of the Apollo Sea unless they accepted liability for the spill.
Bar to Toxic Waste Ship A Croatian ship has been unable to unload its 97 t of toxic waste. The cargo was originally unloaded in Colombia's port of Cartagena in March but later was returned to the vessel by the Colombian authorities. The ship, the 15 642 dwt Triglap; was ordered to leave Colombia at the end of July. Ecuador then refused it entry and later, as the ship headed for Lima's port, E1 Callao, Peru banned it from entering and anchoring in any Peruvian port. The ban was specified by Peru's navy, transportation ministry, port and ecological authorities. The ship is operated by Croate lines and bears a Croatian-Slovenian flag. The waste contains heavy metals such as zinc, cadmium and lead, PCBs and medical waste. Earlier, lnterpol had notified a number of countries in the area, Panama, Colombia, Ecuador, Peru and Chile, that the ship would be requesting authority to unload its eight containers. Chile was the most recent to put a ban on the ship's docking.
