[Display omitted] •Synergies of AgNPs at low doses (0–60μM) 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 CO...
