NATO’s bombardment of Yugoslavia seems not to have caused significant environmental damage, U.N. officials and some environmental groups said yesterday. Still, an official from the U.N. Environment Programme will continue to assess the situation during a visit to Yugoslavia this week as part of a larger U.N. humanitarian team. Yugoslavia has claimed that massive amounts of poisonous gases were being released into the air and were sickening thousands, and that a nine-mile-long oil spill had contaminated the Danube River. Concerns about dioxin levels have also been raised; early in the bombing campaign, there was a report that the dioxin level over Serbia had increased 15-fold.
