Chennai hits alarming pollution levels
Five air quality monitors were set up across Chennai: The readings of PM 2.5, the most microscopic yet dangerous pollutant, ranged from unhealthy to hazardous levels. Exposure to PM 2.5 causes lung diseases and enhances cardiovascular diseases. Of the five locations, Teynampet, Kuruvimedu, Eldams Road, Kodungaiyur and Ennore, Eldams Road recorded the lowest measurement 10 out of 16 times. PM 2.5 of 22.5-micrograms/cubic metre is equivalent to smoking a cigarette. While the WHO’s permissible PM 2.5 level is 10, India’s is 60. There were instances when the city reached PM 2.5 levels of 180 micrograms/cubic metre.
PM10 levels are also on the rise. Even as tanneries discharge chemicals, citizens burn garbage in open spaces adding to the misery. Cold, dry weather, pollutants and smoke, have together contributed to high smog levels in the city. Apart from Chennai airport frequently shutting down, poor visibility levels have led to road accidents as well. The city is also exposed to harmful levels of silica, iron, nickel, manganese, lead and sulphur, courtesy coal-fired thermal plants in Ennore. These toxins, affect brain development of children.
According to a study by the civil engineering department of IIT-M, Chennai needs 26 air quality monitoring stations. Ronak Sutaria, founder of Urban Sciences, opines that responsive government policy framework must be established: “School timings, especially timings for outdoor/playground activities can be adjusted based on real-time PM2.5 levels,” he suggests.
