| Abstract: | The nitrate of vegetables of non-envorimental-pollution vegetable base in western Chongqing were investigated.The results showed that the nitrate concentrations in vegetable samples was in turn green leaf vegetables(810.2 mg/kg)>onion garlic vegetables(631.9 mg/kg)>root vegetables(571.8 mg/kg)>fruit vegetables(307.6 mg/kg)>melon vegetables(289.1 mg/kg).The vegetables investigated were polluted at different extent by nitrate,but not serious;The green leaf vegetables were the worst polluted,belonged to middle... |
