Results from Beachwatch 2001, the Marine Conservation Society's survey of beach litter, will be discussed at the North Sea Conference this week.
Michael Meacher, the minister for the environment, will use the report to underpin the Government's pledge to reduce coastal pollution. Delegates at the North Sea Conference will state their commitment to tackle marine litter in a ministerial declaration to be signed on 21 March.
More than 980 volunteers recorded and removed 222,704 items from 194 beaches around the UK during the weekend of 15 and 16 September last year.
Sam Fanshawe, director of conservation at the Marine Conservation Society, said: "Government and industry must take action to address litter as a significant source of pollution in our seas and everyone from beach visitors to fisherman must take more care with their domestic waste."
