London (CNN)Flying insects are contaminating new environments by eating microplastics in polluted waters and carrying them through the air, a new study has found.
Flying insects could carry microplastics through air, study finds
UK researchers found that microplastics -- pieces of plastic less than 5 millimeters in size -- remain in the bodies of mosquitoes and other waterborne insects even after they become flying adults.
The findings mean that pollution from plastics being dumped into our oceans is being carried into the air, and raises concerns that birds and other creatures that eat the insects are also being contaminated.
The team from the University of Reading in England and Queen's University in Belfast, Northern Ireland, inserted two minuscule pieces of polystyrene, each weighing just over one gram per cubic centimeter, into young mosquitoes and observed the insects throughout their life cycles.
They found that the particles did not disappear from the mosquitoes' systems after the insects moved between life stages and started to fly, and were present inside the fully formed insects.
