kerala's last five year's pollution
Answers
Kerala’s most-polluted cities are Kochi and Thiruvananthapuram and air pollution is increasing steadily in the state with the average PM 10 (particulate matter 10 micrometers or less in diameter) levels touching the permissible limit of 60 microns on most days a month. This was evident in the data compiled by the pollution control board (PCB).
Answer:Kerala's most-polluted cities are Kochi and Thiruvananthapuram and air pollution is increasing steadily in the state with the average PM 10 (particulate matter 10 micrometers or less in diameter) levels touching the permissible limit of 60 microns on most days a month.ne particles (PM2.5) pose greatest health risk. These fine particles can get deep into lungs and some may even get into the bloodstream, Exposure to these particles can affect a person’s lungs and heart. Coarse particles (PM10-2.5) are of less concern, although they can irritate a person’s eyes, nose and throat (United States Environmental Protection Agency, 2018). Hence Central Pollution Control Board (CPCB) eliminated SPM in ambient air from the standard in November 2009 (National Ambient Air Quality Status and Trends in India-2010). (Kerala State Pollution Control Board, 2010) (KSPCB) is a subsidiary of CPCB and this instruction has been followed. Subsequently in all the Water and Air Quality Directories published by the KSPCB after 2010 have not included data on SPM (Cropper, et al., 1997; Dcruz, et al., 2017; Khan and Ghouri, 2011; Waseem, et al., 2013).
However, the formula for calculating API remains unchanged and the resultant API values tend to be smaller by ignoring SPM values from the calculation of API. The entire data for this study were obtained from various issues of Water and Air Quality Directory published by KSPCB.
