Volunteers in Quang Tri Province in central Vietnam have collected six tons of oil sludge that washed up on the coast the past week and are clearing two more tons from a beach.
The source of the oil slick is not known though it has polluted around eight kilometers of coast, the media quoted some locals as saying.
A source from the province environment department said the department had mobilized hundreds of volunteers to collect the sludge and separate the oil an d sand using shovels and nets.
The source estimated two other tons to have mixed with the sand.
Nguyen Truong Khoa, deputy director of the department, said the oil has made local beaches look ugly and dirty.
It would also affect seafood farms situated along the coast, he said.
