The rain brings relief. It also brings plastic.
बारिश राहत लाती है। लेकिन प्लास्टिक भी लाती है।
After weeks of severe heatwaves across north and central India, the monsoon is close. IMD predicted onset over Kerala by 26 May, but the criteria remain unmet. The revised estimate points to early June. When the first showers arrive, millions will step outside to feel the rain.
Rain does more than cool the air. A 2026 study published in Science Advances measured airborne plastic in two megacities and found that rainfall-driven wet deposition is a dominant pathway for removing micro- and nanoplastics from the atmosphere (Hu et al., Science Advances, 2026). The particles come from road dust, synthetic textiles, packaging waste and industrial emissions. Rain brings them to the ground, into the soil and into drinking water.
Airborne particles smaller than 1 micrometre are inhaled with every breath and can reach deep into the respiratory tract. Research suggests nanoplastics may reach the brain via the nasal olfactory pathway (Barbato et al., Science of The Total Environment, 2025). A 2025 Nature Medicine study by Nihart et al. detected nanoplastics in human brain tissue at concentrations higher than in liver or kidneys. Samples from 2024 contained significantly more plastic than those from 2016.
At IIT Patna and NIT Patna, researchers found that post-monsoon microplastic concentrations in the Ganga at Varanasi were higher than pre-monsoon levels, confirming that rainfall flushes plastic into the river system (Singh et al., Environmental Monitoring and Assessment, 2024).
Once dispersed, no method can extract nanoplastics from air, water, soil or living tissue. None of the mass-produced plastics biodegrade in any meaningful way (Geyer et al., Science Advances, 2017).
When indoors during rain, keeping windows closed reduces airborne particle entry. Use steel or copper vessels for water. Reduce single-use plastic at home.
