Another 'toxic school' case leads to closure of Chinese chemical works

Industrial park told to cease production after 20 students fell ill in Hai'an, on the heels of poisoning scare involving 500 pupils in another part of same province

Authorities have ordered the closure of a chemical industrial complex in eastern China after children at a local primary school came down with mysterious nosebleeds and skin complaints that their parents blamed on pollution.

The case comes just days after hundreds of students in the same region were revealed to have fallen ill, some severely, after attending a school built on a toxic waste dump.
