Pharmaceutical products (PPs) and nanoplastics (NPs) are prominent emerging contaminants that pose serious threats to marine ecosystems. The present study aimed investigate both pristine combined toxicity of PPs (metronidazole, diclofenac, ibuprofen) polystyrene (PSNPs) with amine (NH2-PSNPs) carboxyl (COOH-PSNPs) surface functionalization on microalgae Chlorella variabilis. Toxicity assessment included the evaluation growth inhibition, total reactive oxygen species production, malondialdehyde content, antioxidant activity, photosynthetic activity. Furthermore, changes in functional groups algae after exposure were examined. correlation among endpoints was assessed using Pearson cluster heatmap analysis. Zeta potential analysis hydrodynamic size measurements revealed PSNPs became unstable presence PPs. This instability facilitated aggregation rapid settlement PSNPs, consequently impeding their direct interaction algal cells. Growth inhibition results indicated variabilis exhibited minimal when exposed (1 mg L-1), whereas L-1) caused substantial inhibition. Notably, lower compared PSNPs. independent action model combination showed an antagonistic mode interaction. reasons for decreased observed mixture can be attributed diminished oxidative stress enhanced These findings provide valuable insights into role modulating towards microalgae.

Plastics have conveyed great benefits to humanity and made possible some of the most significant advances modern civilization in fields as diverse medicine, electronics, aerospace, construction, food packaging, sports. It is now clear, however, that plastics are also responsible for harms human health, economy, earth's environment. These occur at every stage plastic life cycle, from extraction coal, oil, gas its main feedstocks through ultimate disposal into The extent these not been systematically assessed, their magnitude fully quantified, economic costs comprehensively counted.The goals this Minderoo-Monaco Commission on Human Health examine plastics' impacts across cycle on: (1) health well-being; (2) global environment, especially ocean; (3) economy; (4) vulnerable populations-the poor, minorities, world's children.

Abstract As an emerging pollutant in the life cycle of plastic products, micro/nanoplastics (M/NPs) are increasingly being released into natural environment. Substantial concerns have been raised regarding environmental and health impacts M/NPs. Although diverse M/NPs detected environment, most them display two similar features, i.e.,high surface area strong binding affinity, which enable extensive interactions between surrounding substances. This results formation coronas, including eco-coronas bio-coronas, on different media. In real exposure scenarios, corona is inevitable often displays variable complex structures. The coronas found to impact transportation, uptake, distribution, biotransformation toxicity particulates. Different from conventional toxins, packages rather than bare particles more dangerous. We, therefore, recommend seriously consideration role safety assessments. review summarizes recent progress eco–coronas bio-coronas M/NPs, further discusses analytical methods interpret structures, highlights provides future perspectives.

Enrofloxacin (ENR) is a broad-spectrum antibiotic widely used due to its efficacy against pathogens. Microplastics (MPs) may bind ENR and reduce efficiency, whereas there would be an increase in toxicity, bioavailability, bio-accumulation rates. Therefore, the hypothesis that interaction between MPs can alter their toxicity bioavailability. The subjective of this study examine various concentrations (0, 1.35, 2.7 ml Kg-1 diet) 1000, 2000 mg alone combination for 21 days. rainbow trout (Oncorhynchus mykiss) economic aquaculture species as experimental model ecotoxicology studies. Blood biochemical analytes indicated led increasing enzymatic activity each biomarker, except gamma-glutamyl-transferase (GGT). Alterations related triglycerides, cholesterol, glucose, urea, creatinine, total protein, albumin blood contents were observed. An elevation levels superoxide dismutase (SOD), malondialdehyde (MDA), glucose 6-phosphate dehydrogenase (G6PDH) was found liver. In contrast, catalase (CAT) glutathione peroxidase (GPx) decreased. Furthermore, decline observed cellular antioxidant (ANT) levels. These findings suggested could affect fish health both independently together. Consequently, determined when present high concentrations, amplified, providing further evidence synergistic impact on toxicity.

The increase of micro- and nano-plastics (MNPs) in aquatic environments has become a significant concern due to their potential toxicological effects on ecosystems, food web dynamics, human health. These plastic particles emerge from range sources, such as the breakdown larger waste, consumer products, industrial outputs. This review provides detailed report transmission dangers MNPs environmental behavior, interactions within webs, emphasizing toxic impact marine life. It explores relationship between particle size toxicity, distribution different tissues, process trophic transfer through web. MNPs, once consumed, can be found various organs, including digestive system, gills, liver. Their consumption by lower level organisms facilitates progression up chain, potentially leading bioaccumulation biomagnification, thereby posing substantial risks health, reproduction, behavior species. work also how persistence bioaccumulation, pose biodiversity disrupt relationships. addresses implications for particularly contaminated seafood, highlighting direct indirect pathways which humans are exposed these pollutants. Furthermore, highlights recommendations future research directions, integration ecological, toxicological, health studies inform risk assessments develop mitigation strategies address global challenge pollution environments.

The global accumulation of plastic waste has reached crisis levels. diverse and multilayered impacts on biological health prompts an evaluation these effects from a One Health perspective, through which the complexity processes can be integrated more clearly understood. Plastic particles ranging nanometers to meters in size are found throughout every ecosystem Earth, deepest marine trenches highest mountains. affects all layers organization, molecular cellular organismal, community, ecosystem-levels. These not only mediated by physical properties plastics, but also chemical polymers, thousands additives combined with plastics during manufacturing, sorbed chemicals microbes that transported waste. Using framework we provide overview following themes: 1) ways across levels 2) how interact between biology, 3) what knowledge gaps exist understanding within scales. We propose potential solutions address this growing crisis, emphasis perspectives consider oneness animals, humans, environment.
