Some 74 metric tons of microplastics dropped out of the atmosphere onto the New Zealand city of Auckland in 2020, according to a study published this week in Environmental Science & Technology — the equivalent of 3 million plastic bottles.

The peer-reviewed study is the first to calculate the total mass of microplastics in a city’s air, and its findings suggest researchers may be dramatically undercounting the global prevalence of airborne microplastics.
