ClearEnvironmental Cadmium Exposure Perturbs Gut Microbial Dysbiosis in Ducks
Environmental cadmium exposure in ducks was found to perturb gut microbial diversity and community composition, with dysbiosis patterns suggesting that heavy metal contamination in agricultural environments can impair gut health in waterfowl.
Plant community responses to polypropylene microplastic and cadmium co-exposure: Implications for mycorrhizal strategies in a coastal wetland
Researchers conducted a mesocosm experiment to assess how polypropylene microplastics and cadmium interact in their effects on coastal wetland plant communities. They found that the combination of microplastics and heavy metals altered soil properties, plant community composition, and root traits in species-specific ways. The study suggests that mycorrhizal strategies play a role in how different plant species respond to this combined contamination.
Effects of cadmium contamination on bacterial and fungal communities in Panax ginseng-growing soil
Researchers examined how cadmium (a toxic heavy metal) contamination in soil affects the microbial communities around ginseng crops, finding that even low cadmium levels significantly disrupted bacterial diversity more than fungal diversity. Certain bacterial groups that tolerate cadmium became dominant, while beneficial microbes declined — changes that could affect soil health and ginseng safety.
A Review on Microorganisms in Constructed Wetlands for Typical Pollutant Removal: Species, Function, and Diversity
This review analyzed the community structure, diversity, and function of microorganisms in constructed wetlands for pollutant removal, examining how microbial communities drive degradation of nitrogen, phosphorus, heavy metals, and emerging contaminants.
Study of Heavy Metals and Microbial Communities in Contaminated Sediments Along an Urban Estuary
Researchers studied heavy metal contamination and microbial community composition in estuarine sediments along an urban waterway, finding that urbanization-driven metal accumulation significantly altered microbial diversity and community structure.
[Effects of Combined Pollution of Microplastics and Cadmium on Microbial Community Structure and Function of Pennisetum hydridum Rhizosphere Soil].
Researchers investigated the combined effects of microplastics (polyethylene and polystyrene at different particle sizes and concentrations) and cadmium on the growth of Pennisetum hydridum and the microbial community structure and function of rhizosphere soil under pot conditions. The results showed that the type, size, and concentration of microplastics interacted with cadmium to differentially affect plant dry weight, cadmium accumulation, and soil microbial diversity indices.
Biofilms in plastisphere from freshwater wetlands: Biofilm formation, bacterial community assembly, and biogeochemical cycles
Researchers studied how bacteria form biofilms on microplastic surfaces in freshwater wetlands and found that these plastic-associated communities differ significantly from natural soil bacteria. The microplastic biofilms had lower diversity but higher activity in carbon processing and nitrogen cycling genes. This means microplastics in wetlands can alter natural nutrient cycles, potentially affecting water quality in ecosystems that many communities rely on.
Plastic particles driving cadmium mobility and nitrous oxide emissions: Revealing microbial Fe–N interactions in wetlands
Researchers exposed wetland soil columns to polypropylene microplastics and found that MPs increased nitrous oxide emissions by 45%, raised exchangeable cadmium fractions by 28%, and decreased plant cadmium uptake by 56%, revealing that microplastics alter both greenhouse gas cycling and heavy metal bioavailability in urban wetlands.
Effects of Exposure to Cadmium, Microplastics, and Their Mixture on Survival, Growth, Feeding, and Life History of Daphnia magna
Researchers examined how polyethylene microplastics altered cadmium toxicity to Daphnia magna, finding that microplastic co-exposure modified cadmium bioavailability and affected survival, growth, feeding rates, and reproductive outcomes in this ecologically important species.
Effects of polyethylene microplastics and cadmium co-contamination on the soybean-soil system: Integrated metabolic and rhizosphere microbial mechanisms
Researchers investigated how polyethylene microplastics and cadmium interact in soybean-soil systems and found that specific microplastic concentrations enhanced cadmium accumulation in roots under moderate contamination. Higher microplastic levels reduced beneficial soil bacteria like Sphingomonas and Bradyrhizobium and suppressed nitrogen-cycling functions. The study demonstrates that microplastics fundamentally alter heavy metal behavior through interconnected plant-metabolite-microbe interactions in agricultural soils.
Aggravation of Cd availability in the plastisphere of paddy soil
Researchers conducted batch microcosmic and bagging experiments in flooded paddy soil to examine how microplastics act as a plastisphere microenvironment influencing cadmium (Cd) availability, finding that the plastisphere altered bacterial community composition with enrichment of Symbiobacteraceae, Rhodocyclaceae, and Bryobacteraceae. These community shifts promoted Fe(III) and sulfate reduction, increasing Fe(II) and sulfide content and thereby aggravating Cd enrichment in the plastisphere under flooding conditions.
Single and Combined Effects of Aged Polyethylene Microplastics and Cadmium on Nitrogen Species in Stormwater Filtration Systems: Perspectives from Treatment Efficiency, Key Microbial Communities, and Nitrogen Cycling Functional Genes
This study examined how aged polyethylene microplastics and cadmium interact in stormwater filtration systems — a water management infrastructure that rarely gets attention in microplastics research. The combined presence of both contaminants disrupted the microbial communities responsible for removing nitrogen from stormwater, affecting key nitrogen-cycling genes and treatment efficiency. The findings highlight that microplastic pollution can undermine the effectiveness of water treatment infrastructure in ways that go beyond the plastics themselves.
Distinct microbial communities in the microplastisphere of inland wetlands: Diversity, composition, co-occurrence networks, and functions.
Researchers collected samples from different inland wetland types to characterize the microbial communities colonizing plastic surfaces (the microplastisphere), finding distinct bacterial and fungal communities compared to surrounding soils. Community composition varied by wetland type and plastic surface, highlighting the ecological diversity of plastic-associated microbiomes in freshwater habitats.
Characteristics analysis of plastisphere biofilm and effect of aging products on nitrogen metabolizing flora in microcosm wetlands experiment
Researchers placed three types of plastic in miniature constructed wetlands for 180 days and tracked how they aged and affected microbial communities. The plastics degraded at different rates, with PVC developing new chemical groups and all surfaces becoming less water-repellent as bacteria colonized them. The plastic surfaces altered nitrogen-processing bacteria in the wetland water, suggesting microplastics can disrupt nutrient cycling in natural wetland ecosystems.
Mechanistic insights into microplastic-mediated shifts in nitrogen metabolism and sensory quality across emergent and submerged-plant wetlands: Evidence from metagenomics and physiological indicators
Researchers exposed surface-flow constructed wetlands planted with emergent and submerged macrophytes to polystyrene microplastics and found a 12.64% reduction in total nitrogen removal in the emergent plant system, driven by shifts in nitrogen-cycling microbial communities. PS-MPs also altered sensory water quality indicators, with effects varying by plant type.
Effects of polyethylene microplastics on cadmium accumulation in Solanum nigrum L.: A study involving microbial communities and metabolomics profiles
This study found that polyethylene microplastics in soil reduced the ability of a plant known for cleaning up cadmium contamination to absorb the toxic metal. The microplastics changed the soil's microbial community and altered the plant's metabolism in ways that disrupted its natural heavy metal uptake process. This is important because it suggests microplastic pollution in farmland could interfere with natural and engineered soil cleanup strategies for heavy metals.
