Air Quality Index in Mysore City, Karnataka State, India

摘要

Air Quality Index (AQI) in seven prime localities of Mysore city was determined using the U.S.EPA AQI calculator. Index values for Particulate Matter (PM) at Manasagangotri campus and Ramaswamy Circle are categorized as unhealthy and residents in these surroundings are advised to avoid prolonged exertion. PM index at Fountain Circle and KIDB area are quite high and categorized as very unhealthy. Five Light Circle, K R Circle and Nehru Circle have highest PM indices and are categorized as hazardous. Index values for sulphur dioxide and nitrogen dioxide are below the standards prescribed in these areas. At some places they appear to be slightly high and people with asthma or other respiratory diseases, elderly persons and children are at risk. Use of electrostatic precipitation at industry levels and diesel particulate filters at vehicle levels may reduce the PM values. Alternate fuel may be another means of reducing particulate matter.
