Microplastics in the marine environment have been an emerging concern worldwide in recent years. They are a particular concern because they are carriers of persistent organic pollutants (POPs) including heavy metals, chemicals, and carcinogens. However, airborne microplastics, as small as 1µm, and their potential effects on the environment and humans are less researched, especially in the South Pacific. This is why it is imperative to find the sources of these microplastics and how far they are transported. This was the first study of this type, and it was done through the set up of new equipment in four countries (Australia, Fiji, Tonga, and Vanuatu), to collect and find the amount and types of microplastics that are being deposited in this region.
