Arsenic and Nickel Enrichment Coefficients for Crops Growing on Coal Ash
Around the city of Tuzla, BiH, soil covered coal ash disposal sites have been used for food and fodder production since 1992. To our knowledge this is the first report on the cultivation of coal ash disposal sites for agriculture purposes. We observed high concentrations of As and Ni in alkaline coal ash. In this paper, we investigated arsenic and nickel transport and accumulation in barley and soybean grown on substrates made up of different soil and ash ratios. After three growth in the greenhouse we observed significant differences (p<0.05) between the Ni enrichment coefficients of Dora cultivar of soybean and Rex cultivar of barley, but no significant difference between the As enrichment coefficients of soybean and barley. Dora cultivar of soybean and Rex cultivar of barley showed very low uptake of arsenic, the enrichment coefficient varied between 0.05 % and 0.51 % depending on the crop and the treatment. The nickel enrichment coefficient of Rex cultivar of barley varied between 0.01% and 0.94%. The enrichment coefficient for Ni in Dora cultivar of soybean indicated higher uptake and varied between 5.64% and 34.79%.
