Why in news
Scientists at IISER Kolkata published a study revealing that residents in major Indian cities inhale an average of 132 micrograms of microplastics daily, posing significant public health risks.
Background
The study identified 11 types of plastics in the air, with fragments primarily originating from packaging and tire wear. Lead researcher Dr. Gopala Krishna Darbha advocated for banning single-use plastics and promoting recycled fabrics to mitigate these risks.
