Algae found in another China lake

Blue-green algae has appeared in an east China lake but does not threaten water supplies, Xinhua reported on Thursday, a week after a fast-spreading algae bloom polluted drinking water in a neighbouring province.
Environmental officials in Anhui province were closely monitoring the potentially poisonous algae in Lake Chao, China’s fifth-largest freshwater lake, Xinhua reported.
"The algae is only in the western part of the lake (Lake Chao) and will not pollute the whole lake," Xinhua quoted Zhang Zhiyuan, chief engineer of the Anhui environmental protection bureau, as saying.
Algae is common in fresh water worldwide, but some types can produce dangerous toxins.
