Vehicular emissions that release toxic nanoparticles in Delhi may be hazardous to health, according to a study. Nanoparticles or ultrafine particles are usually defined as a particle of matter that is between 1 and 100 nanometres (nm) in diameter and are invisible to the naked eye. Due to rapid urbanisation, Delhi experiences frequent pollution events, and the particulate matter load exceeds the prescribed limit often.
The study, led by researchers from the Delhi Technological University (DTU), analyses nanoparticles (10 to 1090 nanometre) during different emission scenarios, seasonal and meteorological conditions in two phases: April to June 2021 (Period I) and October to November 2021 (Period II).
