“…Soil samples comprising 10.08% sand, 56.04% silt, and 33.88% clay were air-dried and ground through a 2.0 mm sieve. Biochar, using a maize straw as the feedstock due to its abundance in agricultural waste, was fabricated through a stepwise heating procedure at a final temperature of 600 °C under limited oxygen conditions. , The basic properties of the soil with or without biochar and maize straw biochar are presented in Tables S1 and S2, respectively. Cadmium (Cd), with the property of universality and persistence in contaminated agricultural soil, was chosen as the target pollutant and purchased from the National Analysis Center for Iron and Steel (Shanghai, China).…”

The global prevalence of antibiotic resistance genes (ARGs) is of increasing concern as a serious threat to ecological security and human health. Irrigation with sewage and farmland application of manure or biosolids in agricultural practices introduce substantial selective agents such as antibiotics and toxic metals, aggravating the transfer of ARGs from the soil environment to humans via the food chain. To address this issue, a hyperaccumulator (Sedum plumbizincicola) combined with biochar amendment was first used to investigate the mitigation of the prevalence of ARGs in cadmium and oxytetracycline co-contaminated soil by conducting a pot experiment. The addition of biochar affected the distribution of ARGs in soil and plants differently by enhancing their prevalence in the soil but restraining transmission from the soil to S. plumbizincicola. The planting of S. plumbizincicola resulted in an increase in ARGs in the soil environment. A structural equation model illustrated that mobile genetic elements played a dominant role in shaping the profile of ARGs. Taken together, these findings provide a practical understanding for mitigating the prevalence of ARGs in this soil system with complex contamination and can have profound significance for agricultural management in regard to ARG dissemination control.

“…Driven by the possibility to create either a highly charged surface and multiple functional groups or hydrophobic surfaces, biochar is emerging as an effective and safe natural adsorbent that can capture CO 2 229 and remove diverse organic contaminants 152 (e.g., antibiotics, aromatic dyes, agrochemicals, polychlorinated biphenyls, and polycyclic aromatic hydrocarbons) and inorganic contaminants (e.g., phosphate, ammonia, sulfide, and heavy metals) from solid, aqueous, and/or gaseous media. 137 , 230 , 231 , 232 As a soil amendment, it can improve plant productivity and photosynthesis rate by enhancing the physical, chemical, and biological properties of the soil, 233 thereby contributing to C sequestration in terrestrial ecosystems and mitigating climate change. 234 Biochar addition to agricultural soils has improved soil water availability, water holding capacity, and nutrient availability, 235 , 236 , 237 increased soil microbial biomass and activity, 238 reduced risk of crust formation and soil erosion, 239 enhanced antibacterial activity, 240 and reduced mobility and toxicity of environmental pollutants in the soil.…”

Global development has been heavily reliant on the overexploitation of natural resources since the Industrial Revolution. With the extensive use of fossil fuels, deforestation, and other forms of land-use change, anthropogenic activities have contributed to the ever-increasing concentrations of greenhouse gases (GHGs) in the atmosphere, causing global climate change. In response to the worsening global climate change, achieving carbon neutrality by 2050 is the most pressing task on the planet. To this end, it is of utmost importance and a significant challenge to reform the current production systems to reduce GHG emissions and promote the capture of CO 2 from the atmosphere. Herein, we review innovative technologies that offer solutions achieving carbon (C) neutrality and sustainable development, including those for renewable energy production, food system transformation, waste valorization, C sink conservation, and C-negative manufacturing. The wealth of knowledge disseminated in this review could inspire the global community and drive the further development of innovative technologies to mitigate climate change and sustainably support human activities.
