Chromium Concentrations and Regional Distribution of Urban Soils in Suzhou City

Abstract:

An intensive investigation of 55 samples which have been collected from different functional areas was conducted to study concentrations and distribution of chromium in urban soils of Suzhou by X-Ray fluorescence spectrometer, and the method of Geoaccumulation index. The results indicate that the chromium content in Suzhou soils is from 45 to 144 mg/kg, with an average value of 73.42 mg/kg; and distribution characterized of different functional areas as follows: Industrial areas > Commercial areas > Areas around station > Residential areas>Urban green space; the accumulation index values is between 0.81 and 1.91, which is non-polluting or moderately polluted.
