Characterization of contaminants and evaluation of the suitability for land application of maize and sludge biochars

Popis výsledku v původním jazyce

Prior to the application of biochar as an agricultural improver, attention should be paid to the potential introduction of toxicants and resulting unintended impacts on the environment. In the present study, the concentrations of polycyclic aromatic hydrocarbons (PAHs), heavy metals, and mineral elements were determined in maize and sludge biochars produced at 100 A degrees C increments between 200 and 700 A degrees C. The concentration ranges of total PAHs were 358-5,136 mu g kg(-1) in maize biochars and 179-70,385 mu g kg(-1) in sludge biochars. The total heavy metals were detected at the following concentrations (mg kg(-1)): Cu, 20.4-56.7; Zn, 59.7-133; Pb, 1.44-3.50; Cd, < 0.014; Cr, 8.08-21.4; Ni, 4.38-9.82 in maize biochars and Cu, 149-202; Zn, 735-986; Pb, 54.7-74.2; Cd, 1.06-1.38; Cr, 180-247; Ni, 41.1-56.1 in sludge biochars. The total concentrations of PAHs and heavy metals in all maize biochars and most sludge biochars were below the control standards of sludge for agricultu
