Abstract Air quality Index (AQI) is a tool which is implemented to assess the qualitative and quantitative status of air pollutants. Four distinctive pollutants; PM10, PM2.5, SO2 and NO2 were used to compare the prevailing ambient air quality in the study region-Ludhiana, the industrial city in the north Indian state of Punjab. The AQI for Ludhiana has been compared and, the ambient air quality data for the same has been obtained for Punjab Agricultural University, Ludhiana from Central Pollution Control Board (CPCB). The data has been compared for fifteen days before and after the lockdown amid COVID-19. Air quality information uncovers that during lockdown period PM10 and PM2.5 levels were decreased by around 35 to 40%, which might be clarified as conceivable decrease from production sector, transportation, and residue. AQI of Ludhiana revealed that the primary reason for the poor air quality is P.M 10 and P.M 2.5 which significantly reduced to around 10 to 35 percent during pandemic lockdown.

Diwali Festival

Diwali-the festival of lights, is celebrated in India, every year during October or November with great fireworks display which contributes to pollution of air. In order to assess the impacts of fireworks on ambient air quality during Diwali festival in Katra town, Jammu , (J&K); monitoring of RSPM, NRSPM, SO2 and NO2 during day and night times for Pre-Diwali (day before Diwali); Diwali and Post-Diwali (day after Diwali) for two successive years i.e. 2011 and 2012 has been carried out in a residential area. The air quality levels observed on Diwali has been compared with the air quality levels observed before and after Diwali which has revealed considerable increase in RSPM, NRSPM, SO2 and NO2 concentration due to Diwali fireworks. On Diwali day, the concentration of  RSPM, NRSPM, TSPM, SO2 and NO2 was found to be 118.27µg/m³,  153.2µg/m³,  271.47µg/m3, 6.61µg/m3 and 10.51µg/m3 respectively in 2011 and 141.2µg/m³, 199.14µg/m³,  340.34µg/m³, 7.06µg/m³ and 10.53µg/m³ respectively in 2012.These concentrations were found to be 1.75,  1.57, 1.65, 1.73 and 1.52 times higher  in 2011 and 1.86, 2, 2, 1.47 and 1.39 times higher in  2012,  when compared with the respective concentrations of  normal day. The higher level of these pollutants due to fireworks during Diwali festival poses serious health hazards to the inhabitants of the area.

Jharia Coalfield

India is in the list of fastest growing countries of the world. India's energy needs are also increasing due to population and industrial growth for improving quality of living style. In India, coal is major input infrastructure industries for example Power plants, Steel plants and Cement industries. India’s 52% of primary energy is coal dependent1. 66% of India's power generation depends upon coal production1. Jharia Coalfield (JCF) is falling in the Lower Gondwana Coalfields of India. The area of the JCF is about 450 km2. It is important for the major supply of precious coking coal required for steel plants in India. It is located in Dhanbad district of Jharkhand state of India, The latitude is 23° 39' to 23° 48' N and longitude is 86° 11' to 86° 27' E for the Jharia coalfield. Based on environmental parameters, all the 103 mines of BCCL have been grouped under 17 Clusters. A cluster consists of a group of mines with mine lease boundary lying in close vicinity and includes-Operating mines, Abandoned/ closed mines and proposed projects.The focused study area is in the western part of the Jharia coalfield is named as Cluster XV group of mines of BCCL consists of four mines, Kharkharee Colliery (UG), Dharmaband Colliery (UG), Madhuband Colliery (UG) and Phularitand Colliery (UG) .The present study was carried out with the objective to measure the ambient air quality of the study area with reference to particulate matter (SPM, PM10 & PM2.5). Ambient air monitoring results have shown that the observe air quality were found within the limit prescribed by MoEF / CPCB. It may due to Underground mines as there are pollution causing lesser activities involved in the UG mining process compared to opencast mining. Implementation of Master plan for Jharia coalfields for environmental management has also improve the air quality in the area10,11.

Air Sampler

A comprehensive study on the air quality was carried out in four locations namely, Tiruchengode Bus Stand, K.S.R College Campus, Pallipalayam Bus Stop and Erode Government Hospital to assess the prevailing quality of air. Ambient air sampling was carried out in four locations using a high volume air sampler and the mass concentrations of PM10, PM2.5, SO2, NOX and CO were measured. The analyzed quality parameters were compared with the values suggested by National Ambient Air Quality Standards (NAAQS). Air quality index was also calculated for the gaseous pollutants and for Particulate Matters. It was found that PM10 concentration exceeds the threshold limits in all the measured locations. The higher vehicular density is one of the main reasons for the higher concentrations of these gaseous pollutants. The air quality index results show that the selected locations come under moderate air pollution.

The present study examines the variation of ambient aerosol (PM10) concentrations in Karachi, city. Samples were collected from ten different locations, representative of urban background, residential, traffic and industrial areas from 2007 to 2011. At each location, PM10 was measured continuously from 08:00 am to 06:00 pm at local time. The maximum 10 h average particulate matter (PM10) mass concentrations were found at Tibet Centre (440.1mg/m3) and minimum at PCSIR Campus (21.7mg/m3) during 2008. A rising trend during 2008 may be due to the civil works for bridges and extension of roads at different locations in Karachi. The results also suggest that urban traffic and industrial areas appeared to have higher PM10 concentration than residential and background areas.
