The Lincolnshire coastline is starting to feel the impact of a collision between a tanker and a container ship earlier this month.
Clumps of tiny, molten plastic pellets, known as nurdles, have been washed up on beaches including Skegness.
Black mounds of varying shapes and sizes could be seen on the sands of the popular resort.
The pellets have also been washing-up on the beaches of North Norfolk on the other side of The Wash.
In Lincolnshire, a team from East Lindsey District Council has been clearing-up.
The owners of the cargo ship Solong have admitted the pellets, which were in containers on board, were released because of the crash.
The ship was in collision with tanker Stena Immaculate, under the American flag, carrying aircraft fuel.
The crash happened off East Yorkshire on March 10.
“The counter pollution retrieval operation remains ongoing, with HM Coastguard and other specialist counter pollution assets continuing to assist this response. This includes supporting local authorities who are leading the onshore response in both Norfolk and Lincolnshire,” said Chief Coastguard Paddy O’Callaghan, who added aerial surveillance flights would continue to monitor the situation.
Members of the public are being asked to contact Humber Maritime Rescue Coordination Centre on 0333 382 0580 with details, including a What Three Words app location.
