Pollution AssessmentUpdated on : 12 Sep 2017

Air Quality Index of Central Zone

Under National Ambient Air Quality Standards, 2009; 12 pollutants i.e. PM10, PM2.5, SO2, NO2, NH3, Pb, O3 , CO, Ni, As, B(a)P & Benzene are notified based on short term & long term monitoring for Industrial/residential and Sensitive/ecological areas. In Central zone, under National Air Monitoring Program (NAMP), a huge quantity of data generates daily/monthly/annually for prescribed parameters PM10, SO2 and NO2. To make this huge data more representative and understandable, the concept of Air quality Index (AQI) evaluated by CPCB.

Out of 12 notified parameters, AQI was calculated for 03 parameters (PM10, SO2 and NO2) monitored under NAMP in central zone. The calculated values were categorized in 06 pollution categories (Good, Satisfactory, Moderate, Poor, Very Poor & Severe) reported in AQI document.

In Rajasthan state total 21 NAMP stations are operational in Industrial & Residential areas of 05 districts i.e. Jaipur (06), Jodhpur (06), Alwar (03), Udaipur (03) & Kota (03). The AQI calculated for 06 consecutive years (2010 to May 2015). At all monitoring stations the Air quality Index (AQI) was Moderate in nature which suggests that it may cause breathing discomfort to the people with lung disease such as asthma and discomfort to people with heart disease Children and older adults. At few stations of Alwar, Jodhpur & Jaipur the air quality index was found to be even Poor that means it may cause breathing discomfort to people on prolonged exposure and discomfort to people with heart disease

In Chhattisgarh state total 08 NAMP stations are operational in Industrial & Residential areas of 03 districts i.e. Korba (03), Raipur (02) & Bhilai (03). Based on the available NAMP monitoring data of September 2014 to January 2015, Air Quality Index was calculated. Data of few monitoring stations were not provided either due to rain Or instrument failure. In Raipur district, one monitoring station established in Industrial area at M/s WoolWorth India Pvt Ltd, Sarora shown increasing trend of air pollution; from Poor to Very Poor quality of air. Which suggest that breathing in this ambient environment may cause respiratory illness to the people on prolonged exposure. Effect may be more pronounced in people with lung and heart diseases.

In Madhyapradesh state 9 cities are categorized as Non-attainment cities based on NAMP data of 2008 to 2010. Total 22 NAMP stations are operational in these non-attainment cities i.e. Ujjain (04), Nagda (02), Dewas (01), Bhopal (05), Indore (03), Gwalior (02), Jabalpur (02), Sagar (01) and Satna (02). Based on the available data AQI was calculated. NAMP station of Nagda shown improvement trend w.r.t. 2013 & 2014. Whereas, at most of the NAMP stations Air quality Index (AQI) was found to be Moderate in nature which indicates that it may cause breathing discomfort to the people with lung disease such as asthma and discomfort to people with heart disease Children and older adults.
