BACKGROUND: Biochar (BC) has a great potential for enhancing soil fertility and carbon sequestration while facilitating beneficial waste disposition. Therefore, it is essential to assess and mitigate any inadvertent consequences associated with soil biochar amendment. Earthworm activity is very vital in the soil system, yet there are a limited number of studies that have examined their impact resulting from biochar application to soil. METHODS AND RESULTS: In this study, the survival, growth, reproductive tests, and oxidative DNA damage tests (measured by 8.hydroxydeoxyguanosine (8.OHdG) and catalase (CAT) activities) to assess the potential toxicity to earthworm Eisenia fetida in artificial soil amended with BCs were investigated. The BCs derived from perilla meal, sesame meal, and pumpkin seed were pyrolyzed at 300 and 550℃, and then amended with soil at a rate of 5%. All the earthworms survived, but lost weight compared to control soil after 28 day incubation period. Moreover, the BC.amended soils did not significantly affect the cocoon numbers of earthworms. Slightly higherconcentrations of 8.OHdG and CAT were observed in earthworms present in BC.treated soil than those in control soil. Furthermore, the 8.OHdG concentrations in the soil amended with BC produced at 550℃ were greater than those at 300℃, and it slightly decreased as the incubation time increased. CONCLUSION: These observations could be due to higher contents of toxic metal(loid)s and also higher pH in BCs pyrolyzed at 550℃ than 300℃. While BC is efficiently being used in agricultural fields, this study suggests that it is required to assess the unintended negative impacts of BC on soil ecosystems.
