Agricultural environments are becoming increasingly contaminated with plastic pollution. Plastics in the environment can also provide a unique habitat for microbial biofilm, termed 'plastisphere', which support persistence of human pathogens such as Salmonella. Human enteric Salmonella enterica serovar Typhimurium enter agricultural via flooding or from irrigation water. Using soil mesocosms we quantified ability S. to persist on microplastic beads two agriculturally relevant soils, under ambient and repeat flood scenarios. persisted plastisphere 35 days both podzol loamy soils; while during multiple events was able survive up 21 days. could dissociate migrate through leachate, importantly colonise new particles soil, suggesting that pollution soils aid facilitate further dissemination within environment. The potential increased survival food production due contamination poses significant public health risk, particularly potato root vegetable systems where there is direct contact crops.

Nanoplastics are ubiquitous in ecosystems and impact planetary health. However, our current understanding on the impacts of nanoplastics upon terrestrial plants is fragmented. The lack systematic approaches to evaluating these limits ability generalize from existing studies perpetuates regulatory barriers. Here, we undertook a meta-analysis quantify overall strength nanoplastic developed machine learning approach predict adverse identify contributing features. We show that primarily associated with toxicity metrics, followed by plant species, mass concentration size, exposure time medium. These results highlight threats depend diversity reactions across molecular ecosystem scales. rooted both spatial functional complexities and, as such, specific plastic characteristics environmental conditions. findings demonstrate utility interrogating data literature update risk assessments evidence-based policy actions.

Large quantities of microplastics are regularly discharged from wastewater treatment plants (WWTPs) into the aquatic environment. Once released, these plastics can rapidly become colonised by microbial biofilm, forming distinct plastisphere communities which may include potential pathogens. We hypothesised that protective environment afforded would facilitate survival pathogens during transitions between downstream environmental matrices and thus increase persistence for dissemination The Escherichia coli, Enterococcus faecalis Pseudomonas aeruginosa colonising polyethylene or glass particles has been quantified in mesocosm incubation experiments designed to simulate, (1) direct release WWTPs freshwater seawater environments; (2) movement following discharge WWTP through river-estuary-marine-beach continuum.

Increasing studies of plastisphere have raised public concern about microplastics (MPs) as vectors for pathogens, especially in aquatic environments. However, the extent to which pathogens affect human health through MPs remains unclear, controversies persist regarding distinct pathogen colonization on well transmission routes and infection probability MP-associated from water humans. In this review, we critically discuss whether how approach humans via MPs, shedding light potential risks involved. Drawing cutting-edge multidisciplinary research, show that some may facilitate growth long-range specific environments, ultimately increasing risk We identify MP- pathogen-rich settings, such wastewater treatment plants, aquaculture farms, swimming pools, possible sites exposure pathogens.

Sewage-associated plastic wastes, such as wet wipes and cotton bud sticks, commonly wash up on beaches; however, it is unclear whether this represents a public health risk. In study, sewage-associated waste, naturally occurring substrates (seaweed sand), were collected from ten beaches along the Firth of Forth estuary (Scotland, UK) analysed using selective media for faecal indicator organisms (FIOs) E. coli intestinal enterococci (IE), potential human pathogens (Vibrio spp.). Minimum inhibitory concentration (MIC) analysis was used to determine antibiotic resistance in selected strains. FIOs Vibrio more often associated with sticks than seaweed, there evidence several antibiotics. This work demonstrates that plastics sewage pollution can facilitate survival dissemination thus, could present an yet unquantified risk at beach.
