文摘
- •
Synergies of AgNPs at low doses (0–60 μM) in 2,4-DCP biodegradation were observed.
- •
Maximum degradation rates of 2,4-DCP were more than 94% at low-level AgNPs.
- •
AgNPs-mediated toxicity to P. chrysosporium arised from the “Trojan-horse” effects.
- •
2,4-DCP was completely degraded into CO2 and H2O at optimum conditions.
- •
Amino, carboxyl, carbonyl and sulfur-containing groups assist in Ag transportation.
