Abstract: There was a significance to guarantee the quality and safety of agricultural products, when learning correlations between fluorine contents in surface soils and crops around fluorite-rech area. Fluorine contents were analyzed in surface farm-soils and crops in fluorite mining area located in the central Zhejiang Province. It was found that average total fluorite contents ranged from 485 to 772 mg/kg in soils and 0.05 to 2.98 mg/kg in crops. The over-standard rate of F in rice and rapeseed sample were 58.3 and 30.0 per cent respectively, while fluorite contents in fruit and vegetables below 1.0mg/kg. It was found that the cause of fluorite in crops was soil fluorine. The absorption and accumulation of fluorite in rice and rapeseed were stronger that in fruit and vegetables. There was a significant correlation between the content of total fluorine in rice or rapeseed and that in the soil. The result provided a theoretical basis for the adjustment of planting pattern.
