Abstract: Dry deposition samples, after a fire in a plastic scrap market in Delhi, were collected and analysed for pH, electrical conductance, Cl, NO3,SO4, Na, K, Mg and Ca. The fluxes of Na, Ca, Cl and NO3 were observed to be 16, 7, 4 and 4 times higher than those under normal conditions. The higher fluxes of Cl may be attributed to the pyrolysis of PVC, while the higher fluxes of other components may be due to their presence in PVC or other materials burnt in the fire. Assuming that the fire influenced 1/4 part of Delhi, the total deposition of Ca, Cl, Na, NO3, SO4, K and Mg was estimated to be 61, 21, 16,16, 11, 11 and 5 tones, respectively, due to this fire incident.
