Russian bug spray, a council bin and the remains of a 1980s picnic are among the most unusual items found washed up on beaches cared for by the National Trust.
The charity has unveiled the 20 oddest objects found on its shores - which include a working Canadian research buoy, tiny plastic soldiers and thousands of neon pink detergent bottles - to shine a spotlight on marine pollution.
The problem continues to blight UK beaches despite growing public awareness of issues such as single-use plastics ending up in the seas, the charity said.
The National Trust is calling on staff, volunteers and the public to take part in beach or river cleans as part of a campaign to encourage people to tackle pollution and help the environment.
While some of the finds are of recent items and debris, some illustrate just how long waste can last in the seas.
