Non-methane volatile organic compounds emitted from domestic fuels in Delhi: Emission factors and total city-wide emissions

In controlled laboratory conditions, 62 samples of domestic fuels collected from 56 grids Delhi were burnt to quantify the emissions 23 non-methane volatile organic compounds (NMVOCs), i.e., alkanes (11), alkenes (6), alkynes (1) and aromatic (5). The used for residential activities comprised 20 unique types fuel woods, 3 species crop residue, dung cakes coal. These are primarily cooking water/space heating during winters. current study reports total emission budget NMVOCs burning over Delhi. Furthermore, this also compares differences in EFs which calculated different cycles sample collection methods. flaming stage using canisters analysed then compared with same emitted complete cycle. addition this, 10 consumption hotspot identified Delhi; based on ground survey simulated results. annual usage year 2019 was found be 0.415 Mt/yr (million tonnes) 12.01 Gg/yr NMVOC cake wood dominated 6.6 5.4 Gg/yr, respectively. canister online method differ significantly each other. presented enhanced cycle by ~7 times suggests that data analysis period play a pivotal role preparation an inventory estimating budget. • Emission factor •Comparison two stages •City wise •Different hotspots Delhi, India
