“…In the another study HI values for heavy metals were found to be < 1 in children and adults, showing non-carcinogenic risks ( Botle et al, 2020). However, a recent study at the Agra site (Sah et al,2022) the carcinogenic risks of Cd for children and As, Cr and Ni for both adults and children has been observed, as in their study the concentrations were higher than 1 × 10 -6 . Furthermore, the total non-carcinogenic risk for both adults and children, exceeded the safe level (= 1).…”

In Indian cities, airborne particulate matter, PM2.5, is related with regional or across border problem and that of PM 10 with local-land urban problem. The present study was carried out for risk assessment of PM10 and PM2.5 and its associated carbonaceous component and heavy metals of an experimental agriculture farm site of Delhi, India. In our studies, at the agricultural site which is surrounded by heavy traffic and industries related sites, concentrations of both PM10 and PM2.5 varied significantly from 136.34 to 176.66 µg/m3 and 56 to 162 µ/m3 respectively. However, the concentrations of NOx were relatively higher during the months of February and March. The concentrations of O3 in the present study, were observed to be the highest in February. In general, the Hazard index for both adults and children population was reported to be < 1, which indicated the probability of non-carcinogenic risks to both populations as negative.

“…Apart from this, about 10-15 lakhs vehicles are on road each day from nearby states (Tiwari et al 2022). In addition to nearby sources, there are also the Mathura re nery, Firozabad glass industries, and various brick kiln factories located approximately 40 kilometers away from Agra city (Sah et al 2022).…”

The current study was an attempt to measure ambient air quality in term of PM 2.5 and associated heavy metals at two different sites near very busy crossing on National Highway with the help of ne particulate dust sampler. The Average mass concentration for PM 2.5 was 77.59μg/m 3 and 72.86μg/m 3 at semi-urban and urban sites. From the outcomes it was determined that the in uence of PM 2.5 concentrations was greater at the Semi-urban than urban site. Concentrations of PM 2.5 have been compared with WHO, NAAQS and USEPA standards and was found to be exceeded than prescribed limit. Among analyzed heavy metals, Ca (11.652 µg/m 3 ), showed the highest concentration due to various construction materials, such as cement, brick lime and concrete as well as road dust, accompanied by Al (1.397µg/m 3 ) and Fe (0.973µg/m 3 ). The concentration of metals followed the trend Ca>Al >Fe > K >Pb>Mn> Co > Cr > Cu > Ni and Ca>Al >Fe > K >Mn>Pb> Cr > Ni > Cu > Co at both the sites. The Enrichment factor (EF) values concluded that Al, K, Fe, and Mn as less enriched (EF< 10) while Co and Pb had been classi ed as very highly enriched (EF>100). Hazard Quotient (HQ) for Al, Cr, Mn, and Ni is lower than the safe level (HQ= 1) whereas Excess Lifetime Cancer Risk (ELCR) of Cr (VI) and Ni exceeded the respective safer limit ELCR≥ 10 -6 indicating long-term exposure to particulate-bound toxic metals via inhalation could lead to cancer in approximately one child and four adults per million.
