Emissions from incinerators on the Thai resort islands of Phuket and Koh Samui are affecting human health, alleges Greenpeace, an international pressure group. The emission levels of toxic chemicals by these incinerators is about 15-40 times higher than the legal limits in Japan and Europe, the group said. The health of people living within three kilometres of these incinerators is at risk not only from airborne pollutants but also from contaminated vegetables, eggs and milk.
