“…During pre-monsoon, BC concentration peak in the evening shifted towards the late evening hours due to the shift of fall in temperature and the reduction in boundary layer height which is associated with seasonal and meteorological condition at the site, but an elevated peak is observed on 26 March between 18:30 and 20:30 h, which may be associated with the burning of woods and biomass. This may be attributed to the pre Holi burning (Holika) when the massive wood and carbonaceous materials are burned in India for celebrating the Holi festival [ 40 ].…”

The tropospheric NO2 concentration from OMI AURA always shows high concentrations of NO2 at a few locations in India, one of the high concentrations of NO2 hotspots is associated with the locations of seven coal-fired Thermal Power plants (TPPs) in Singrauli. Emissions from TPPs are among the major sources of black carbon (BC) soot in the atmosphere. Knowledge of BC emissions from TPPs is important in characterizing regional carbonaceous particulate emissions, understanding the fog/haze/smog formation, evaluating regional climate forcing, modeling aerosol optical parameters and concentrations of black carbon, and evaluating human health. Furthermore, elevated BC concentrations, over the Indo-Gangetic Plain (IGP) and the Himalayan foothills, have emerged as an important subject to estimate the effects of deposition and atmospheric warming of BC on the accelerated melting of snow and glaciers in the Himalaya. For the first time, this study reports BC concentrations and aerosol optical parameters near dense coal-fired power plants and open cast coal mining adjacent to the east IGP. In-situ measurements were carried out in Singrauli (located in south-east IGP) at a fixed site about 10 km from power plants and in transit measurements in close proximity to the plants, for few days in the month of January and March 2013. At the fixed site, BC concentration up to the 95 μgm−3 is observed with strong diurnal variations. BC concentration shows two maxima peaks during early morning and evening hours. High BC concentrations are observed in close proximity to the coal-fired TPPs (>200 μgm−3), compared to the outside domain of our study region. Co-located ground-based sunphotometer measurements of aerosol optical depth (AOD) show strong spatial variability at the fixed site, with AOD in the range 0.38–0.58, and the highest AOD in the range 0.7–0.95 near the TPPs in transit measurements (similar to the peak of BC concentrations). Additionally, the Angstrom exponent was found to be in the range 0.4–1.0 (maximum in the morning time) and highest in the proximity of TPPs (~1.0), suggesting abundance of fine particulates, whereas there was low Angstrom exponent over the surrounding coal mining areas. Low Angstrom exponent is characterized by dust from the unpaved roads and nearby coal mining areas. MODIS derived daily AOD shows a good match with the MICROTOPS AOD. The CALIPSO derived subtypes of the aerosol plot shows that the aerosols over Singrauli region are mainly dust, polluted dust, and elevated smoke. The preliminary study for few days provides information about the BC concentrations and aerosol optical properties from Singrauli (one of the NO2 hotspot locations in India). This preliminary study suggests that long-term continuous monitoring of BC is needed to understand the BC concentrations and aerosol optical properties for better quantification and the estimation of the emission to evaluate radiative forcing in the region.

“…Many researchers [17,27,30] have been updated the similar kinds of work of presented study on air pollution especially in holi festival based on incremental concentration of particles, chemical properties, contribution to atmosphere due to bonfire activities etc., however probably first measurement was reported based on impact of PM especially fine particle (PM 2.5 ) and its association with number of hospital admissions, which was missing in literature. In India, 68% of total population still belongs to remote / rural area, therefore assessment of association between changes in air quality and hospital admission performed in western region of India.…”

In this paper we observe the association between changes in air quality and number of hospital admission during "holi-the festival of colours". Proposed research performed during holi festival, where playing colour are very common practice. Fine particle and its ion concentration were analyzed by air monitoring and ion chromatography. Reported concentration profile of fine particle were 25-40 μg m −3 , 54-171 μg m −3 , and 35-70 μg m −3 , for PM 2.5 and while for PM 10 , 53-251 μg m −3 , 92-291 μg m −3 , and 58-277 μg m −3 , respectively, which are more than the permissible limit. The major anions (Sulphate, Nitrate, and Chloride) and cations (Sodium, Potassium, and Magnesium) were obtained on fine particle with higher permissible limit. PM 2.5 were 67 μg m −3 , which was 1.11 times and ~ 2 times higher than Indian and WHO standards, moreover, probably first time reported during holi festival. Very limited study is available on association between fine particle (PM 2.5) available in air quality and number of hospital admission. The pollution generated due to holi festival and hospital admission related data were collected in four different locations and nine hospitals near by the selected study area, respectively. Empirical relationships have been developed between particle concentration due to colour festival and hospital admission.
