Crews remove oil lumps from Suomenlinna shores

Small, dried oil lumps have washed ashore on Suomenlinna in Helsinki, and the cleanup may take several days, Yle reports.

Helsinki’s Rescue Department is collecting oil caught in bladderwrack and among rocks on the shore. The lumps are about 10 metres from the waterline, which the department says suggests they washed ashore in early November.

No oil has been detected in the sea. An investigation found that the substance is light mineral oil, but its origin is unknown.
