Researchers found highest recorded level of microplastics on seafloor

A team of researchers found the highest levels of microplastics ever recorded on the seafloor with up to 1.9 million particles per square meter.

Each year over 10 million tons of plastic waste finds its way into the oceans, though only 1% is found in shallower waters while 99% is thought to occur in the deep oceans, where microplastics and plastic fragments get transported by deep-sea currents where they are concentrated in 'microplastic hotspots'.
