The seasonal changes of F,S and Cl contents of eatable parts of 20 vegetable samples collected from four vegetable production bases of Nanjing were analyzed for three successive years,The results show that the average F,S,Cl contents of those sample are all higher than that of the controls The differe-ces were significant between leaf vegetable;and controls,the oth-ers did not show obvious differences.The F pollution of those vegetables is higher than Cl and S, and the Cl and S contents showed a decreasing trend. It is concluded that the industrial air pollution has certain inference on vegetable quality,and the prop-er distribution of vegetable production bases are suggested.
