Abstract
tThe extensive use of silver nanoparticles (SNPs) as antimicrobial in food, clothing and medicine, leadsinevitably to a loss of such nanomaterial in soil and water. Little is known about the effects of soilcontamination, in particular, on microbial cells, which play a fundamental ecological role.In this work, the impact of SNPs on forest soil has been studied, investigating eco-physiological indica-tors of microbial biomass and microbial diversity with culture-dependent and independent techniques.Moreover, SNPs bioavailability and uptake were assessed. Soil samples were spiked with SNPs at two dif-ferent concentrations (10 and 100 g g−1dw) and incubated with the relative controls for 30, 60 and 90days. The overall parameters showed a significant influence of the SNPs on the soil microbial community,revealing a marked shift after 60 days of incubation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
