Delhi's Invisible Threat: Microplastic Inhalation Soars in Summer

A study reveals that residents of Delhi inhale nearly double the microplastic particles in summer compared to winter. The research indicates significant exposure among different age groups and identifies local sources of microplastics. The study highlights health risks and suggests Delhi as a hotspot for airborne microplastic exposure.

Residents of Delhi inhale almost twice as many microplastic particles in summer as they do in winter, a new study has found. The daily exposure to these harmful particles rises from 10.7 in winter to 21.1 in summer, representing a 97% increase, according to research from the Indian Institute of Tropical Meteorology and Savitribai Phule Pune University.

The study, which measured microplastic exposure across various age groups, found children and toddlers face significant risks. Winter season exposure for children aged 6 to 12 stands at 8.1 particles a day, increasing to 15.6 in summer. Infants also face an increased risk, inhaling 6.8 particles daily in summer.

Conducted at Lodhi Road in Delhi, the study found polyethylene terephthalate to be the most common microplastic. The findings underscore the severe health risks associated with long-term exposure, including potential respiratory issues like asthma and bronchitis. The study indicates Delhi is particularly vulnerable due to its dense population and high pollution levels.
