Yesterday being a Sunday, the air pollution recorded at the pollution monitor stationed closest to HSR Layout, near Silk Board, showed healthy levels between 2pm and 6pm.
However, at 7pm, the level shot up past the safety mark of 100 to reach a 'moderate' level of pollution, which is unhealthy for sensitive groups like people with respiratory or heart disease, the elderly and children.
The Air Quality Index (AQI) is higher when converted from ug/m3, the measurement used by the Central Pollution Control Board that has installed these monitors across the city. The highest pollution in the last 24 hours was recorded at 8am today - 170 AQI. This is unhealthy for everyone and not just those who are sensitive to air pollution.
