A lead soil contamination from a continuous point source near Turin (Italy) was examined. According to the Gaussian plume model the distance of maximum concentration at ground was estimated downwind an incinerator located in an agricultural and woodland area. The Relative Topsoil Enhancement (RTE) of lead, taken as a tracer of dust fall-out, rose more than 600%, but not at the forecasted distances. A geostatistical approach confirmed that the RTE was spatially dependent and a Kriging map well described the soil pollution after a long term emission.

Abstract
A lead soil contamination from a continuous point source near Turin (Italy) was examined. According to the Gaussian plume model the distance of maximum concentration at ground was estimated downwind an incinerator located in an agricultural and woodland area. The Relative Topsoil Enhancement (RTE) of lead, taken as a tracer of dust fall-out, rose more than 600%, but not at the forecasted distances. A geostatistical approach confirmed that the RTE was spatially dependent and a Kriging map well described the soil pollution after a long term emission.
