Challenges in safe environmental applications of biochar: identifying risks and unintended consequence

Biochar, Год журнала: 2025, Номер 7(1)

Опубликована: Янв. 14, 2025

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.

Biochar derived from plant biomass has great potential for the decontamination of aqueous media. It is need hour to test biochar economical, easily available, and novel materials. In this regard, present study provides insight into sorption two heavy metals, i.e., cadmium (Cd) nickel (Ni), using native Arachis hypogaea its prepared through pyrolysis. The effect different factors, including interaction time, initial concentration adsorbate, temperature, as well sorbent dosage, was studied on Cd Ni a batch experiment. Characterization biowaste surface morphology functional group identification executed Fourier transform infrared (FTIR) spectroscopy scanning electron microscopy (SEM). Results revealed presence groups such -OH adsorbent, which plays an important role in metal attachment. SEM reveals irregular makes it easy Thermogravimetric analysis shows stability A. up 380 °C compared with adsorbent. adsorption efficacy found be higher than that both metals. best (94.5%) observed at 40 ppm, adsorbent dosage 2 g, contact time 100 min, temperature 50 °C. While optimum conditions (97.2% adsorption) were reported 2.5 60 offers better ions raw samples low concentrations. Isothermal studies show mechanism physical adsorption, negative value Gibb's free energy confirms spontaneous nature reaction. An increase entropy favors process. decent alternative eliminate solution instead costly adsorbents.

The adsorption characteristics of Cd2+ and Pb2+ with biochars have been widely reported. However, the desorption characteristics, chemical speciation, stability adsorbed on remain unclear. In this work, rice straw were obtained at different pyrolysis temperatures (RSBC300, RSBC500, RSBC700). speciation Cd- Pb-loaded investigated through Tessier sequential extraction agents, possible quantitative mechanisms metal-laden revealed. Pyrolysis temperature influenced properties obviously, including surface morphology, element mineral composition, carbon structure defects. RSBC700 RSBC500 exhibited highest capacity toward Pb2+, respectively. majority metal ions are distributed in carbonate fraction exchangeable fraction. Cd Pb all metal-loaded showed a high risk assessment code values larger than 50 %. HCl EDTA-2Na could desorb most from Cd-laden biochars, high-temperature Pb-laden biochars. Precipitation minerals (Qpre, 52.77 %–82.37 %) interaction π-electrons (Qπ, 16.57 %–30.26 main for whereas precipitation 18.82 %–58.71 ion exchange (Qexc, 19.18 %–48.81 removal Pb2+. Therefore, not stable easily released to environment, which potential environmental risk.
