Microplastics in Air Far Lower Than Previously Estimated: Study
Scientists from the University of Vienna did a big study on tiny plastic pieces called microplastics in the air.
They found that there are way fewer microplastics in the air than people thought before.
They took lots of measurements from different places around the world and found that the amount of microplastics changes a lot depending on where you are.
For example, in some places in China, they found very few microplastics, but in some cities in the UK, they found a lot more.
The scientists think that land, like cities and farms, puts about 20 times more microplastics into the air than the oceans do.
Even though there are fewer microplastics than we thought, the scientists say we still need to be careful because these tiny plastic pieces can still be bad for our health.
Microplastic emissions in the air are 100 to 10,000 times lower than previous estimates.
Land sources contribute 20 times more microplastics to the air than oceans.
Microplastic concentrations vary significantly by location, ranging from 0.004 to 190 particles per cubic meter.
Annual microplastic emissions from land are estimated at 610 quadrillion particles, while oceans contribute 26 quadrillion.
The study was conducted over a decade with 2,782 measurements from 283 global locations.
