Description Temporal & spatial variations in ground-level total non-methane hydrocarbon
(TNMHC) were studied in Nagpur urban agglomeration (UA) for a year over three seasons
viz. post-monsoon (September-October), winter (January-February) and summer
(May-June) in 2013-14. Ground-level TNMHC showed low to moderate spatial (over residential,
commercial, traffic intersections, residential cum commercial sites) and temporal
(at 7:00, 13:00; 18:00 and 23:00 h in all three seasons) variations. There was no specific
increasing or decreasing trend with time, either within a day or a season. Daily mean concentration
of TNMHC (averaged over concentrations at 7:00, 13:00; 18:00 and 23:00 h)
ranged from 0.88-1.73 ppmV, 1.75-4.04 ppmV and 1.20-1.53 ppmV at residential sites;
2.99-6.47 ppmV, 1.52-7.38 ppmV and 0.98-1.63 ppmV at traffic site; 0.83-1.15 ppmV, 2.03-
3.24 ppmV, 1.1-1.70 ppmV at residential cum commercial sites and 1.05-4.79 ppmV, 6.2-
8.58 ppmV, 0.34-0.64 ppmV at the purely commercial site, during post-monsoon, winter
and summer, respectively. Occasional spikes (TNMHC>10 to
