Pollutant levels at Deonar were 40 times over limit
Concentration of particulate matter (PM) at the Deonar dumping ground reached 40 times the 24-hour permissible limit on Tuesday afternoon, when a fire raging for more than a week was said to be brought under control. The high levels of PM posed a grave risk to environment and health of people living around the 127-year-old dumping ground.
PM are tiny suspended pollutants, consisting of soot, chemicals and organic substances, which can enter the respiratory system.
HT has accessed pollution levels from five types of PM (PM1, PM 2.5, PM4, PM10 and PM15) measured by the Environmental Policy and Research India (EPRI) before and after dust suppressants were sprayed within a 200 sq m area inside the dumping ground, to prevent toxic pollutants from dispersing in the air and surrounding areas. Even after the dust suppressants were sprayed, concentration of PM was 37 times higher than permissible limits.
