|a Anaerobic digestion technology is widely used for treatment of swine and dairy manures in livestock farms, but the digested swine and dairy manures (SD-S, SD-D) must be properly disposed. In this study, hydrothermal carbonization (HTC) was used to deal with SD-S and SD-D. The resulting hydrochars (HC-S and HC-D) were investigated for the migration, speciation and potential environmental risk of metal(loid)s therein. The results showed that about 20%-50% of metal(loid)s in SD-S and 11%-36% in SD-D lost through the dissolution of the metal(loid)s in solution during HTC process. The remaining metal(loid)s were more concentrated in HC-D compared to HC-S. The concentrations of water-extractable metal(loid)s showed clear decrease trend in HC-S and HC-D. The bioavailable metal(loid) fraction (acid soluble/exchangeable fraction and reducible fraction) were transformed into the stable fraction (residual fraction) during HTC process. The results indicated that HTC process could immobilize most metal(loid)s leaching from HC-S and HC-D, except for Zn and Cd in HC-S. The maximum leaching concentrations of all metal(loid)s happened at pH of 2; meanwhile less fraction of metal(loid)s can be leached out from HC-D into water. The environmental risk assessment values suggested that HC-D was more environment-friendly than HC-S. This study provides a useful support for reuse of HC-S and HC-D as pollution remediation and soil amendment with very low leaching toxicity and potential ecological risk of metal(loid)s
