Kolkata tops Indian cities in airborne microplastic pollution: Study
A new study from IISER Kolkata found that Kolkata has the highest levels of inhalable microplastics in India, with residents breathing in about 2.9gm over their lifetime—that's roughly a small plastic bottle's worth.
Delhi isn't far behind, while Chennai and Mumbai have lower levels.
Why it matters for your health
These tiny plastic bits can reach deep into your lungs and bloodstream, carrying harmful chemicals like phthalates and heavy metals such as lead—sometimes above safe limits.
The study also found microbes hitching a ride on these particles, raising concerns especially for kids' health.
Where all this plastic comes from
Most of the microplastics come from polyester clothing fibers, along with packaging waste and vehicle wear.
Levels spike after monsoon and during chilly evenings when more people wear synthetics and air circulation drops.
Experts suggest using less single-use plastic, choosing cotton clothes, and improving waste management to help cut down exposure.
