SHANGHAI — An oil spill off of China's eastern coast kept hidden from the public for weeks has caused long-term environmental damage that will harm the area's fishing industry, state media reported on Tuesday.
Dead seaweed and rotting fish could be spotted in waters around Nanhuangcheng Island in Shandong province, near the site of an oil spill that began "in early or mid-June" but was only made public on Friday, the China Daily said.
"The environmental impact caused by the oil leak is long-term," the newspaper quoted a local fisheries association official as saying.
Nanhuangcheng Island is about 75km from the offshore oil field in Bohai Bay, where the leak occurred.
"The oil leak will definitely influence the fishing industry nearby," the official continued.
The state maritime bureau said that an area measuring 840 square kilometers had been badly polluted due to the spill, Xinhua news agency reported.
The state-owned China National Offshore Oil Corporation (CNOOC) attempted to stem anger over its failure to warn the public about the spill, claiming that government authorities were aware of the incident all along.
"We reported the spill to authorities soon after they took place and treatment of the spill is under supervision," CNOOC spokesman Jiang Yongzhi was quoted as telling the Global Times.
The spill was first reported by a member of the public on the popular Chinese micro-blogging site Sina Weibo on 21 June.
CNOOC confirmed nine days later that US oil company ConocoPhillips, which operates the Penglai 19-3 oil field where the leak originated, first reported oil on the surface of the sea "in early or mid-June," the China Daily said.
CNOOC said its cleanup work was almost finished and that the spill had been brought under control.
