Int'l - China's port city Qingdao suffers worst algae infestation

China’s eastern port city Qingdao is experiencing the worst ever algae infestation in the region, with more than 1,700 square km of coastal area blanketed by harmful green seaweed, also known as “green tide”.

BEIJING (Reuters) -China’s eastern port city Qingdao is experiencing the worst ever algae infestation in the region, with more than 1,700 square km of coastal area blanketed by harmful green seaweed, also known as “green tide”.

Qingdao has suffered from algae for 15 years. It normally appears from late spring and lasts for three to four months, damaging the local marine ecosystem as algae take oxygen from other organisms and churn out toxic odours while decaying.

More than 1 million tonnes of algae are expected to be removed from coastal waters, state-backed China News reported on Monday, citing an expert from the Institute of Oceanology at Chinese Academy of Sciences (IOCAS).

Qingdao city authorities had dispatched over 12,000 vessels to collect some 450,000 tonnes of algae by last week.
