Slick experiment
The Baltic nations have begun an experiment to mark the contents of oil tankers so they can identify the culprits in cases of oil pollution, the Swedish Board of Navigation and Shipping has said. For the trials, which will extend to the end □f the year, port authorities have been issued with fine particles of many different types of metals. When a tanker discharges oil, the authorities put a coded blend of these particles into the ship’s tanks and send the blend composition and tanker name to a central registry. If the ship later dumps oil at sea while washing its tanks, a small sample of the slick will identify the source of the pollution.—Stockholm.
