A new study from researchers at the University of Auckland has found about 74 million metric tons of microplastics rain down over Auckland, New Zealand each year. This amount of microplastics weighs around the same as over 3 million plastic water bottles.
The study, published in the journal Environmental Science & Technology, analyzed over nine weeks’ worth of samples, collected in September through November 2020, in two sites in Auckland. The results showed an average of about 4,885 airborne microplastics in one square meter in just one day. Comparatively, London had about 771 as of 2020, Hamburg had around 275 in 2019, and Paris had an average of 110 in 2016.
