The Hindu, Kochi, Feb 2017: The ambient black carbon (BC) concentration in the city has been found to be about five times higher than the limits set by the World Health Organisation (WHO). It was found that the city had BC measurement of over 95,000 ng/m3 (nanogram per cubic metre) whereas the WHO mentions levels of BC not more than 20,000 ng/m3 to be safe.

The BC values were found by Biju Thomas, paediatric respiratory medicine consultant from Singapore, who undertook a study to find a person’s exposure to black carbon in Kochi.
