Abstract Microplastics represent a pervasive contaminant in aquatic ecosystems, posing substantial risks to biota. This study sought elucidate the toxicological impacts of three prevalent plastic polymers high-density polyethylene (HDPE), low-density (LDPE), and polypropylene (PP) both mono co-exposure scenarios on Daphnia. Employing range endpoints, investigation assessed Daphnia magna's ingestion, bioaccumulation, population density, swimming behavior, reproduction rate response microplastics measuring 0–32 µm, which were synthesized laboratory using virgin polymer beads . The findings revealed that synergistic effects medium pose greater hazard organism than mono-exposure individual (PP, LDPE, HDPE). In scenerio, LC50 value decreased 77 mg/L, compared 120, 123, 109 mg/L for PP, HDPE, respectively. magna exhibited more pronounced co-exposure, characterized by reduced survival rates, increased microplastic rates densities. Furthermore, led erratic movements relative mono-exposure, with immobility energy deficiency observed across all exposure types, albeit magnitude settings.

Aquatic plants, seagrasses, macrophytes, mangroves, and riparian vegetation are responsible for some of the most important ecosystem services provided on Earth. Given their role in trapping plastics along rivers, we propose a new service plastic entrapment by global plants. Although research started recently to study plastics, little is known about patterns retention remobilization through different habitats. those gaps, synthesize data plants providing conceptual model describe processes vegetation. Our results demonstrate how has pivotal entrapping across spatial temporal scales, finding higher density rather than adjacent water area.

Coastal areas are prone to plastic accumulation due their proximity land based sources. vegetated habitats (e.g., seagrasses, saltmarshes, mangroves) provide a myriad of ecosystem functions, such as erosion protection, habitat refuge, and carbon storage. The biological physical factors that underlie these functions may an additional benefit: trapping marine microplastics. While microplastics occurrence in coastal sediments is well documented, there conflicting evidence on whether the presence vegetation enhances relative bare sites influence microplastic remain understudied. We investigated how structure type influences simulated wetland.

Abstract Background Marine macroalgae (‘seaweeds’) are a diverse and globally distributed group of photosynthetic organisms that together generate considerable primary productivity, provide an array different habitats for other organisms, contribute many important ecosystem functions services. As result continued anthropogenic stress on marine systems, macroalgal species face uncertain future, risking their vital contribution to global productivity service provision. Scope After briefly considering the remarkable taxonomy ecological distribution macroalgae, we review how threats posed by combination anthropogenically induced stressors affect seaweed communities. From there highlight five critical avenues further research explore (long-term monitoring, use functional traits, focus early ontogeny, biotic interactions impact litter coastal vegetation). Conclusions Although parallels with terrestrial vascular plant responses stressors, note impacts some (e.g. habitat loss) much less keenly felt in oceans than land. Nevertheless, common communities, climate change will inevitably be most pernicious threat future persistence species, communities While understanding simultaneous environmental is complex exercise, our attempt synergies priorities elucidate trends mechanisms response, may yet offer small this goal.

Microplastic (MP) pollution is a significant threat to marine environments not only due its widespread presence but also because of the alarming emergence ingestion records among benthic organisms. In this study, MP prevalence was assessed in stomach crustaceans Lithodes santolla and Grimothea gregaria gastropods Nacella deaurata N. concinna. Particles were analyzed with Fourier-transform infrared (FTIR) spectroscopy. Overall, analysis revealed that particles mainly microfibers composed cellulose/rayon (60%), followed by MPs (30%), undetermined registered library (10%). Higher found grazers compared scavengers, latter showing low particle their contents. Grazers presented significantly higher abundance per individual lower size ingested scavengers. When grouped trophic levels, tertiary consumers abundances larger sizes particles. Pearson's correlations showed no associations between abundance/size species body size. The results study may suggest continued associated accidental organisms will alter energy flow organic matter availability food webs, perform certain functional traits more susceptible being affected.

Recently, effect MPs agricultural ecosystem has gained momentum. Hence, present review examines impact microplastics crop systems mechanism underlying its toxicity. The current revealed that most conducted at laboratory scale under controlled conditions. Additionally, it was observed polystyrene (PS) followed by polyethylene (PE) are studied polymer type, while plants wheat maize. Hitherto, literature suggest microplastics' influence plant growth can be negative or sometimes neutral; in some cases exerts hormetic which depends other factors determining growth. Notably, main mechanisms through mechanical damage, alteration soil properties, leaching additives. Overall, with burgeoning research interest this aspect, significant implications for toxicity throws light need to develop novel guidelines toward sustainable use plastics sector.
