Students sickened at school built on toxic site

The Ministry of Environmental Protection started an investigation on Sunday into what caused about 500 students at Changzhou Foreign School in Jiangsu province to come down with a range of pollution-related illnesses.

The school had relocated in September to a facility built on a toxic site.

The spate of illnesses that flared since then include leukemia, dermatitis, eczema, bronchitis and blood abnormalities.
