Generally, the ILCR of assessed carcinogens decreases in the following order PHMs [ILCR (95%CI) 2.08 × 10-4 to 1.54 × 10-3] > formaldehyde [ILCR (95%CI) 9.04 × 10-6 to 6.87 × 10-5] and PPAHs [ILCR (95%CI) 5.97 × 10-6 to 4.51 × 10-5] > benzene [ILCR (95%CI) 2.99 × 10-7 to 3.00 × 10-6]. The results indicated that more attention should be paid to the ILCR of PM2.5. Cooking method significantly affect the ILCR of carcinogens in COF excluding formaldehyde. The ILCRs of COF from water-based cooking methods are greater than those of oil-based cooking ones.Biochar has the potential to enhance microbial-mediated phosphorus (P) cycling in soils, but the underlying mechanisms remain largely unknown. We hypothesized that biochar amendment could enhance the production of acid and alkaline phosphomonoesterase, phosphodiesterase and P mineralization, which may vary depending on the P input. To test this hypothesis, we assessed the impacts of rice straw biochar application (0 and 4%) under different P-input rates (0, 30 and 90 kg P ha-1) on the relationships among P fractions, phosphatase activities and alkaline phosphomonoesterase-encoding bacterial (phoD gene) communities in an acidic soil. Biochar application under low P input ( less then 30 kg P ha-1) significantly increased the activities of phosphodiesterase and alkaline phosphomonoesterase but not that of acid phosphomonoesterase and depleted organic P. The results from the structural equation model revealed a dominant role of alkaline phosphomonoesterase in P mineralization. The increase in alkaline phosphomonoesterase activity was not related to an increase in phoD gene abundance but was due to a shift in community composition, which was primarily driven by the soil CP ratio. Microbial network analysis demonstrated a more complex phoD gene community with more functionally interrelated groups as a result of
