摘要
About 128 ha of agricultural soils on the Guandu Plain,Taipei,were characterized as highly contaminated with arsenic (As) (maximum As concentration:500 mg/kg).This study investigates As availability in aerobic soils and explores factors controlling availability.Nine surface soil samples with a wide range of total As were collected from the Guandu Plain.Another eight soil samples collected from representative Taiwanese soil series were spiked with As to 60 mg/kg.
