Microplastic distribution and composition on two Galápagos island beaches, Ecuador: Verifying the use of citizen science derived data in long-term monitoring

Published on ScienceDirect | August 20, 2022


  • Citizen scientists correctly identified plastics or rubber in 93% of particles.
  • Concentrations varied from 0 to >2500 particles m−2 with accumulation gradients.
  • No significant spatiotemporal microplastic variation was measured over a year.
  • Localised high densities of polyethylene pellets were recorded on one island.
  • Simple quadrat/sieve method offers accessible beach microplastic monitoring option.
