The air quality of Sindri after closure of FCI has been assessed with respect to Particluate Matters. The SPM has been found to vary between 99 ug/m3 to 174 ug/m3, PM10 between 60 to 74.5ug/m3 and PM2.5 between 35 to 48 ug/m3. The Air Quality Index has been computed based on the standard break-point definitions and as per CPCB guidelines. The quality index has been assessed for PM10 and PM2.5. On scale 1-10, the Air Quality Index(AQI) has been found in the range of 8 to 10 for PM10 and for PM2.5 the air quality index corresponds to 3. The Air Quality Index on scale 1 to 100 has been found between 41 to 52 for PM2.5. Similarly, on scale 0-500, the AQI with respect to PM10 has been found in the range of 53 to 61 and for PM2.5, AQI has been found in the range of 99 to 132. As per CPCB guidelines, the air quality has been assessed by calculating exceedence factor. The exceedence factor has been found to vary between 0.6 to 0.7 for PM10 and between 0.58 to 0.80 for PM2.5. The Air Quality Index falls under moderate to un-healthy quality of air. A long/ chronic exposure may impart ill-health effect. The need, justification and objective of the paper has been highlighted through a review of literature presented in the introductory part of the paper. Major portion of the study is based on literature survey through standard hand books, journals, Google, Google Medline and Google scholar and information available from the records of Government and non-government organizations with the use of following key words.

Keywords: Air Quality Index (AQI), Air Quality Health Index (AQHI), SPM, PM10, PM2.5.
