“…This fact was associated with the ability of the rain to remove pollutants from the atmosphere. In the atmosphere, the gases are absorbed and the particulate matter is trapped in raindrops falling on the ground (Shukla et al, 2008). In falling, the drops of rain (much larger than drops of water) drag solid particles in their path (dust or contaminants).…”

“…6 further supports this observation. This influence of rainfall on PM is well documented (Shukla et al 2008 and references therein), and furthermore, research indicates that SO 2 and NO 2 are washed out of PM by precipitation (Davies 1976;Chang 1984). The washout could potentially add to the acidification of urban run-off.…”

Whilst vehicular and industrial contributions to the airborne particulate budget are well explored, the input due to building demolition is relatively unknown. Air quality is of importance to human health, and it is well known that composition of airborne particles can have a significant influence on both chronic and acute health effects. Road dust (RD) was collected before and after the demolition of a large building to elucidate changes in elemental profile. Rainfall and PM10 mass concentration data aided interpretation of the elemental data. Quantification of Al, As, Ba, Ca, Cd, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Rh, S, Si, Sn, Ti, V and Zn was carried out. It was found that only Al, K, Mg, Si and S increased in concentration across all size fractions after the building demolition. Risk assessment was then carried out on elements with applicable reference dose values to assess the potential health risks due to the demolition. Significant risk to children was observed for chromium and aluminium exposure. PM10, monitored 40 metres from the demolition site, indicated no abnormal concentrations during the demolition; however, rainfall data were shown to affect the concentration of PM10. The elemental data observed in this study could possibly indicate the role of increased sulphur concentrations (in this case as a result of the demolition) on the buffer capacity of RD, hence leaching metals into rainwater.

“…The work of Hegg and collaborators [9,11], has pointed out this hypothesis more clearly. Shukla et al [17] have studied the removal of gaseous pollutants and particulate matters from the atmosphere by rain using mathematical models. The effect of cloud droplets on the removal of pollutants has also been studied by them [18].…”
