Abstract: How to deal with the coal fly ash drained from the power plants is a crucial problem related to the sustained development of the whole society. Soil amelioration with fly ash is an important approach to comprehensive utilization of the latter However，fly ash contains harmful elements such as Cd, Hg, As, Cr, Pb, Ni, U, Th. How do these elements affect soil and vegetables? Is there an enrichment of harmful elements? The experiment of vegetable and soil amelioration with fly ash from the Second Power Plant in Nanjing has been performed. The applied amount of fly ash was of four levels: 0t/hm2, 15t/hm2, 30t/hm2 and 45t/hm2. The contents of harmful elements of 38 samples, including fly ash rumples, soil samp1es applied with different amount of fly ash and vegetable samples grown in the soil were analyzed. The results show that the contents of harmful elements in the soil and vegetable are lower than the lever stipulated by the state standards about the soil and vegetables. There does not exist a positive correlation between the contents of the harmful dements and the applied amount of fly ash. Consequently, these vegetables are eatable as common vegetables. It is safe to use the fly ash drained from the Second Power Plant in Nanjing into the soil with an amount in the range of present experiment, namely not higher than 45t/hm2
