Toxicity of PM2.5 in Kolkata Spikes Sharply Beyond 70 µg/m³ Bose Institute Study Warns
A recent study by Kolkata’s Bose Institute has revealed a concerning spike in the toxicity of PM2.5 particles once their concentration crosses 70 µg/m³ underscoring the urgent need for stricter pollution controls. The findings suggest that beyond this threshold, the health risks posed by PM2.5 particles increase sharply posing a greater threat to public health than previously understood.
PM2.5, or fine particulate matter with a diameter of 2.5 micrometers or less, is among the most dangerous air pollutants. These particles can penetrate deep into the lungs and bloodstream, leading to serious respiratory, cardiovascular, and neurological issues. The study focused on the oxidative potential (OP) of PM2.5, which measures its ability to generate reactive oxygen species (ROS) compounds that ...
