Blood poisoning disputed in Rayong
Play
Following the discovery of lead contamination in the blood of 42 Rayong schoolchildren in a random test by Thammasat University's Public Health Faculty, Map Pa Wai School director Thianchai Songbundit suspected the cause might be the adjacent Rojana Indu
However, Rayong public health official Dr Krit Palasut said a June 2011 test on 907 students found 82 cases of blood contamination in Pluak Daeng, Nikhon Pattana, Ban Chang and Ban Khai districts. A second round of tests in May found fewer cases of lead poisoning.
Officials have told families to throw away old water and food containers made of metal. They also collected water and air samples for further testing.
