Arsenic concentrations in floodplain soils

摘要

Arsenic concentrations in a Belgian floodplain affected by industrial activities were compared with As concentrations in European floodplain soils from the FOREGS database. The upper 30 cm of the Belgian floodplain soil showed a clear enrichment with As, related to anthropogenic activities, while single extractions indicated that the mobility of As was significantly higher in the upper 12 cm of the soil. Fe was the independent variable that most significantly explained the total content of As in flood- plain soils in the FOREGS database. A regression equation with major elements as independent variables allowed to predict As concentrations in the floodplain soils, and enable d to detect potential anomalies.
