摘要: Abstract A survey was made of the concentration total cadmium and lead in topsoil at 125 sites surrounding several emission sources northern France; one most important lead-zinc smelters Europe among those sources. non-linear regression model evaluated for a single source. The concentrations both metals soil were almost proportional to inverse distance from source square root wind frequency. As pollution present area, an additive linear tested satisfactory adequacy between predicted observed values obtained. Thus, it possible draw precise mapping isoconcentration contour plots pollutants estimate burden that as well relative contribution each global pollution. It also give guidelines more adequate sampling design.
