摘要:
This paper presents maps and analyses of soil contamination by lead and cadmium. Data are for soil samples from the Evin-Malmaison site (Nord Pas-de-Calais, France). The statistical method used to interpolate concentrations of heavy metals enables the drawing of maps and the associated errors. The instrumentation required to follow both the spatial and temporal evolution of these concentrations is discussed. (C) 1997 Elsevier Science B.V.
