Abstract
Biochar has caused great interest due to its sequestrating carbon and improving soil fertilities. It has been increasing attracted and applied to agriculture systems. However, many toxic compounds (e.g., polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds (VOCs),heavy metals) are likely to be formed during biochar production. These compounds may be existed in biochar matrix and even bioavailable to exposed organisms. Therefore, the formation and impact factors as well as the concentrations and bioavailability of these compounds are reviewed.
