Microplastics found in every marine mammal surveyed in UK study

Stranded porpoises, dolphins and seals had average of 5.5 particles in their guts

Microplastics are being widely ingested by Britain's marine mammals, scientists say, with samples found in every animal examined in a study.

The research on 50 stranded creatures including porpoises, dolphins, grey seals and a pygmy sperm whale is the most comprehensive analysis of microplastics in the digestive tracts of both wild cetaceans and seals.
