Abstract The dust fall-out rate, distribution pattern andconcentration of lead in the particulate fall-outmatters in urban Raipur city covering an area of 160 km2 during one hydrological year i.e. November1996–June 1997, has been described. The entire cityhas been divided into 6 zones comprising ofindustrial, commercial, residential and heavy trafficareas. A monthly collection and analysis of dustfall-out rate between 3.0(±0.1) and91.3(±1.2) metric tonnes km-2 month-1 wereobserved at all 6 sampling sites. The total annualflux of lead in the fall-out of the city at differentzones is in the range 0.0065–0.4304 kg km-2yr-1. The results show that dust fall-out and thelead levels both are at higher magnitudes in winterand autumn. These large levels of air pollutants havealso been correlated with some meteorological parameters like relative humidity and temperature, and strong positive correlations have been observed.
