MODELLI DI STUDIO DI BIOMARKERS PER LA VALUTAZIONE DEL RISCHIO DI CONTAMINAZIONE DA NANOPARTICELLE D’ARGENTO NEL SUOLO (PROGETTO INESE)

Il progetto “Impact of Nanoparticles in Environmental Sustainability and Ecotoxicity” (INESE), finanziato dall’Istituto Italiano di Tecnologia (IIT), ha studiato gli effetti delle nanoparticelle (NPs) ingegnerizzate su diversi ecosistemi (acquatici e terrestri), proponendo differenti sistemi biologici di studio (piante acquatiche, ricci di mare, organismi del suolo, pomodoro-impollinatore, ecc). In particolare l’UO dell’Università di Bologna ha focalizzato l’attenzione sullo studio dei modelli di interazione tra particelle di suolo, microorganismi (biomassa microbica), invertebrati (Lumbricus rubellus) e pianta (Solanum lycopersicum). In questa sede verranno riportati i risultati ottenuti d…

Impact of Ag and Co engineered nanoparticles on soil microbial community structure in a soil perturbed by Lumbricus rubellus

Knowledge on the impact of engineered nanomaterials (ENMs) on both human and environment health is scarce. Several studies sustain that soil is the environmental compartment designed to be the major recipient of engineered nanoparticles (NPs). With the aim of investigating the impact of commercially relevant NPs on soil functioning, we compared the effect of Ag and Co NPs, as well as cobalt and silver ions, on soil microbial community in the presence of Lumbricus rubellus. Earthworms specimens were placed in a rich‐C soil and fed with horse manure spiked with Ag‐NPs, Co‐NPs, Ag+ and Co2+ for a total amount of 10 mg of single pollutant kg‐1 soil. At the end of acute exposure (4 weeks) to pol…
