The bioavailability of cobalt and its transfer from soil to vegetables and rice were investigated. Among 312 soils collected from vegetable and paddy fields in the suburban areas of some major cities of Fujian Province, southeast China, total soil Co ranged from 3.5 to 21.7 mg kg(-1), indicating a slight accumulation compared with the background value of the province. DTPA extracted 0.1-8.5% of soil total Co. Total and DTPA-extractable Co correlated with soil pH, CEC, free Fe, total Mn, clay and silt content more significantly in paddy soils than in the soils from vegetable fields. The average Co concentrations in the edible parts of vegetables and rice were 15.4 microg kg(-1) and 15.5 microg kg(-1), respectively. The transfer factor (the ratio of plant Co to soil DTPA-extractable Co, TF(DTPA)) ranged from 0.003 to 0.126 with a median of 0.049. The TF(DTPA) decreased in the order of leafy vegetables > fruit vegetables > root vegetables > rice. The TF(DTPA) of all crops decreased with increasing DTPA-extractable Co. Increase in pH, CEC, organic matter, clay, silt, free iron and total Mn limited the soil-to-plant transfer of Co to varying degrees. The transfer of Co from the soils to the edible parts of the crops was lower than that of Zn, Cu and Cd, but higher than that of Pb in the same areas. The concentrations of Co in rice and vegetables in the study areas were considered to be safe for the local residents because of the slight anthropogenic input and the low transfer potential to the edible parts of Co from the soils.
