Beijing:  The number of people sickened by contaminated water in Southern China has risen to 450, more than double the previously reported figure, state media said on Saturday.

The residents of two villages in southern Guangxi province began showing symptoms of arsenic poisoning last week, including swelling in the face and eyes, and blurred eyesight, the official Xinhua News Agency reported yesterday.

Earlier this week, local officials had said 200 people became ill after drinking water contaminated by industrial waste from Jinhai Metallurgy Chemical, a branch of the state-owned Liuzhou China Tin Company Limited.

Authorities in the nearby city of Hechi said torrential rains from a recent typhoon caused wastewater from the company to overflow into nearby ponds and wells.
