A novel investigation was conducted utilizing calcination technique to stabilize heavy metals and simultaneously remove PAHs in soil. Calcination temperature (300-700°C) was observed to play a dominant role in heavy metal stabilization and PAH removal in soils, whereas calcination time (0.5-8 h) had no significant effect on these contaminants during calcination at different temperatures. An optimal calcination condition for Zn, Cu, naphthalene, and fluoranthene is suggested at 700°C for 0.5 h to achieve the corresponding stabilization or removal efficiency values of 96.95%, 98.41%, 98.49%, and 98.04%, respectively. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6121654/
