Plastics, long-chain artificial polymers, are used worldwide with a global production of 350 million tonnes per year. Various degradation processes transform plastics into smaller fragments divided micro, meso and macroplastics. In various industries, such as construction, certain plastic additives to improve flexibility enhance performance. Plastic include phthalates (PAE), dibutyl phthalate (DPB) diethyl (DEP). Due the use additives, these small different shapes colours present in all environmental compartments. For their characteristics, PAEs can be introduced particularly by ingestion, inhalation dermal absorption. They accumulate human body, where they have already been identified blood, amniotic fluid urine. The purpose this review is gather effects that on systems body. Being endocrine disruptors, erythrocytes how considered targets for xenobiotics analysed. influence reproductive system was also examined. Phthalates therefore often overused. properties, reach tissues negative impact health. aim give an overview presence hazards. Therefore, should reduced, replaced disposal improved.

Rainbow trout (Oncorhynchus mykiss) physiological response to microplastics and enrofloxacin: Novel pathways to investigate microplastic synergistic effects on pharmaceuticals

Aquatic Toxicology, Год журнала: 2023, Номер 261, С. 106627 - 106627

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.

Caffeine (Caff) is one of the most widely used substances in human diet and a well-recognized drug. Its input into surface waters remarkable, but biological effects on aquatic organisms are unclear, particularly combination with pollutants suspected modulatory activity, like microplastics (MP). The aim this study was to reveal impact marine mussel Mytilus galloprovincialis (Lamark, 1819) Caff (20.0 μg L-1) environmentally relevant (Mix) MP 1 mg L-1 (size 35-50 μm) after exposure for 14 days.

Vulnerability of microplastics on marine environment: A review

Ecological Indicators, Год журнала: 2023, Номер 155, С. 111058 - 111058

Опубликована: Окт. 7, 2023

Microplastics (MPs), which are small plastic particles measuring less than 5 mm in size, have emerged as a significant environmental concern marine ecosystems worldwide. The presence of MPs aquatic environments has increased due to the contributions from anthropogenic and terrestrial sources, raising concerns about their abundance organisms. primarily originate photo-degradation larger debris (macroplastics), with release into environment often occurring through breakdown additive compounds. ingestion poses eco-toxicological risks organisms, causing damage gastrointestinal (GI) tracts stomachs affected Approximately 80 % can be classified either primary such those generated during production skincare products, tires, use carriers for pharmaceutical or secondary sources resulting improper disposal plastics near coastal areas water bodies. issue potential effects on ecosystem demands attention. In conclusion, this review provides comprehensive overview vulnerability microplastics environments, consolidating current understanding distribution, fate, ecological impacts. It emphasizes urgent need ongoing research proactive measures mitigate long-term consequences microplastic pollution essential services they provide.

This study investigated the toxicity of polyethylene microplastics (MPs; <0.02 mm) and CuSO4, alone in combination, on freshwater crayfish Pontastacus leptodactylus. In this study, were exposed to PE-MPs (0.0, 0.5, 1 mg L-1) CuSO4·5H2O for a period 28 days. Next, multi-biomarkers, including biochemical, immunological, oxidative stress indicators analyzed. Results showed that co-exposure CuSO4 resulted increased aspartate aminotransferase (AST), alanine (ALT), lactate dehydrogenase (LDH), decreased alkaline phosphatase (ALP), butyrylcholinesterase (BChE), gamma-glutamyl-transferase (GGT). Triglycerides, cholesterol, glucose, albumin content also increased. Although no significant change was observed lysozyme phenoloxidase activities co-exposed 0.5 L-1 MPs their significantly other experimental groups. Oxidative parameters hepatopancreas indicated superoxide dismutase (SOD), glutathione peroxidase (GPx), malondialdehyde (MDA) levels, but catalase (CAT), glucose 6-phosphate (G6PDH), cellular total antioxidant (TAC). sub-chronic confirmed. The confirmed found higher concentrations led more severe effects. Co-exposure primarily compromised endpoints, showing when both pollutants present concentrations.

Опубликована: Май 8, 2024

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.
