Environmental behavior of per- and polyfluoroalkyl substances (PFASs) and the potential role of biochar for its remediation: a review

Biochar, Journal Year: 2025, Volume and Issue: 7(1)

Published: Jan. 17, 2025

Abstract Per- and polyfluoroalkyl substances (PFASs), commonly known as ‘‘forever chemicals’’, are persistent organic pollutants that widely distributed in the environment. Due to their toxicity resistance degradation, PFASs classified emerging contaminants, increasing attention is being paid remediation. Biochar, an environmentally friendly cost-effective adsorbent, shows potential for remediating contamination. The application of biochar remediation has garnered growing interest. Compared other adsorbents, more economical raw materials its preparation readily available. However, there currently no comprehensive review summarizing effects on environmental behavior PFASs. This aims fill gap by providing in-depth discussion synthesis existing literature this area. It focuses PFASs, specifically addressing adsorption mechanisms factors influencing effectiveness A proposed mechanism which photodegrades through generation free radicals, addition conventional (such pore filling, hydrogen bonding, hydrophobic interactions, electrostatic interactions), explored. Furthermore, discusses ability reduce likelihood entering food chain water soil evaluates feasibility limitations using removal. Finally, we identify future research directions support safe effective use remediation, so promote advancement green technologies. Graphic

Biochar-based urea increases soil methane uptake in a subtropical forest

Geoderma, Journal Year: 2024, Volume and Issue: 449, P. 116994 - 116994

Published: Aug. 7, 2024

Novel biochar-based fertilizers, produced by combining biochar particles with chemical have strong potential to enrich soil carbon (C) and nitrogen (N), increase plant productivity. Application of fertilizers modifies microbial community compositions, thereby influencing greenhouse gas emissions, including methane (CH4) fluxes. Due the improved aeration in soils amended particles, we hypothesized that urea would decrease CH4 production oxidation, leading total uptake soil. A three-year field experiment was conducted a subtropical Moso bamboo forest compare impacts traditional on seasonal soil, as well physicochemical attributes. Urea application lowered annual 6 % 16 at 100 300 kg N/ha, respectively, within first year. Biochar-based N/ha increased 12 both second years, whereas effects weakened over time. Soil positively correlated oxidation rate but negatively rate. The urea-induced attributed NH4+ NO3− contents mcrA gene abundance decreased pmoA/mcrA ratio, increasing enhanced labile C supply, which created favorable conditions for methanotrophs. This resulted pmoA accelerating oxidation. Overall, these findings underscore augmenting soils. Notably, transition from China forests alone has lift an estimated 4450 t.

Absence of significant effect of nitrogen addition on soil respiration in a subtropical Chinese fir plantation

Canadian Journal of Forest Research, Journal Year: 2025, Volume and Issue: 55, P. 1 - 9

Published: Jan. 1, 2025

Chinese fir ( Cunninghamia lanceolata (Lamb.) Hook) is one of the most dominant tree species in southern China. However, effect different nitrogen (N) levels on soil respiration subtropical plantations remains unclear. We studied respiration, physicochemical properties, and microbial biomass under four N treatments (control, low-N, moderate-N, high-N). The results showed that high-N increased by 9%, 50%, 79%, respectively, compared to control, but increases did not reach statistical differences. addition significantly decreased pH, tended increase aluminum ions (Al 3+ ). These indicated microorganisms are inhibited enhanced Al content addition, which therefore reduced biomass. negative correlation between suggests reductions may inhibit respiration. ammonium nitrogen, moisture, combined with lower middle growing season end season. This stimulated plant growth absorb more nutrients, intensified plant-microbe competition, lead an autotrophic was higher than decrease heterotrophic Our study highlights isolating quantifying source will be necessary future studies.
