24-hour samples were taken using filters fitted to a low volume air sampler and analysed for PM 2.5 (Particulate Matter or dust less than 2.5 micrometres in size).
"The high concentration of polluting industries in the city’s northern and southern edges is affecting all of Chennai," said Dr Rakhal Gaitonde, a public health specialist.
Also, the levels of calcium silicon and crystalline silica, which are enriched in coal ash were found in the air samples.
