This was highlighted in a study conducted by the Bose Institute, Kolkata, and the Indian Institute of Technology (IIT), Kanpur.
Key Findings
- Key sources of Air pollution: Pollutants enriched with black carbon from Kolkata and the Indo-Gangetic Plain along with localized sources such as biomass burning.
- Rising Reactive Oxygenated Species (ROS): Acidic components of PM2.5 pollutants with heavy metals is fostering the generation of ROS, posing a severe threat to mangrove cells.
- ROS are oxygen-containing radicals that are capable of independent existence with one or more unpaired electrons.
