摘要: The present study deals with the assessment of ambient air quality respect to respirable suspended particulate matter (RSPM or PM10 < = 10 microm) and trace metals (Fe, Zn, Cu, Cr Ni, Cd, Mn Pb) concentrations in RSPM at five locations Renukoot, an industrial area Eastern Uttar Pradesh. 24 hr mean ranged between 69.3 118.9 microg m(-3), which is well within permissible limit (150 m(-3)) national standards (NAAQS) but found higher than prescribed annual daily US EPA (50 m(-3)). was mostly dominated by Fe least Cd among metal analysed. Murdhawa, a commercial place influenced vehicular population, be most polluted Renukoot Dongia nalla (forest area) least. Murdhawa rich Cu indicating contribution mobile sources. Rammandir residential near industry, suggesting point Ni concentration alarmingly high all except nallah, when compared EC (European Commission) (20 ng only as (5 Mean Pb are almost equal locations, significance sources contributing presence these metals. having significant correlation indicate same source PM10. has focused on quantitative variation different PM10, extremely harmful due their toxic carcinogenic nature.
