Did you know the air in big cities isn’t just full of smog and dust, but actual clouds of microplastics? Scientists found up to 180,000 plastic particles per cubic meter floating over places like Guangzhou and Xi’an. These tiny plastics can get into our lungs and even carry chemicals and germs. Rain helps wash them down, but traffic keeps pumping more into the air. Kinda makes you wonder what we’re all breathing in every day! Would you trust your city’s air? #Science #microplastics #airpollution
