Abstract Over the past 10–15 years, biochar has garnered significant global attention in agriculture and environmental science. While most research focused on benefits of application soil enhancement, water quality improvement, climate change mitigation, potential risks associated with its use have often been overlooked. This oversight is critical, as fate contingent upon understanding these risks. Once released into environment, can interact media, potentially releasing pollutants threatening ecosystems. Therefore, it essential to evaluate unintended health during production select appropriate types for sustainable development. review was conducted by systematically analyzing synthesizing relevant studies from Web Science, focusing recent advancements key debates field. It categorizes endogenous exogenous based source carried biochar. The analyzes detail impacts raw materials, preparation processes, scenarios Furthermore, provides a thorough overview adverse effects animals, plants, microorganisms, human health, elucidating mechanisms pollutant release, aging, nano-effects geochemical processes involving Additionally, this summarizes risk assessment methods biochar, providing reference safe development biochar-related research.

Developing algae cultivation for food, chemicals, and bio-energy generates a significant amount of algal waste/residue after utilization. Meanwhile, harmful blooms caused by abnormal proliferation various produce large biomass, posing serious harm to human health, the environment economy. Converting body biochar is crucial method with which take advantage this resource. Biochar usually has specific surface area, developed pore structure, high cation exchange capacity rich functional groups. With stable physical/chemical properties easy modification techniques, posited as an ideal adsorption material. From perspective biomass utilization, paper reviews preparation methods, structural characteristics, physicochemical environmental implications biochar. The effect mechanisms on nutrients, heavy metals, organic matter in water are introduced. In light current research status, challenges faced practical application algae-derived materials pointed out, direction also developed, view providing reference further utilization
