Microplastics and pesticides are emerging contaminants in the marine biota, which cause many harmful effects on aquatic organisms, especially fish. Fish is a staple affordable food source, rich animal protein, along with various vitamins, essential amino acids, minerals. Exposure of fish to microplastics, pesticides, nanoparticles generates ROS induces oxidative stress, inflammation, immunotoxicity, genotoxicity, DNA damage alters gut microbiota, thus reducing growth quality Changes behavioral patterns, swimming, feeding habits were also observed under exposures above contaminants. These affect Nrf-2, JNK, ERK, NF-κB, MAPK signaling pathways. And Nrf2-KEAP1 signalling modulates redox status marinating enzymes Effects found modulate antioxidant enzymes, including superoxide dismutase, catalase, glutathione system. So, protect health from contribution nano-technology or nano-formulations was researched. A decrease nutritional population significantly impacts human diet, influencing traditions economics worldwide. On other hand, traces microplastics habitat water can enter humans by consuming contaminated may result serious hazards. This review summarizes stress caused due nano-particle contamination exposure their impact health. As rescue mechanism, use management disease discussed.

Is Wild Marine Biota Affected by Microplastics?

Animals, Год журнала: 2022, Номер 13(1), С. 147 - 147

Опубликована: Дек. 30, 2022

The present review provides detailed information on the adverse effects of MPs wild marine organisms, including tissue damage, fish condition, oxidative stress, immune toxicity, and genotoxicity. A bibliometric analysis was carried out CiteSpace (version 6.1.R3) (Drexel University, Philadelphia, PA, USA) to verify how many papers studied species. results showed a total 395 articles, but only 22 really presented data or impacts biota, these, 12 articles highlighted negative effects. This shows that observed in organisms were less severe milder than those found experimental conditions. knowledge caused by direct ingestion microplastics animals is still limited; more efforts are necessary fully understand role ecosystem, human health.

Impact of Fibrous Microplastic Pollution on Commercial Seafood and Consumer Health: A Review

Animals, Год журнала: 2023, Номер 13(11), С. 1736 - 1736

Опубликована: Май 24, 2023

The omnipresence of microfibers in marine environments has raised concerns about their availability to aquatic biota, including commercial fish species. Due tiny size and wide distribution, may be ingested by wild-captured pelagic or benthic farmed Humans are exposed via seafood consumption. Despite the fact that research on impact biota is increasing, knowledge role food security safety limited. present review aims examine current microfiber contamination commercially relevant species, chain, probable threat consumer health. available information suggests among edible species also contaminated, but there an urgent need standardize data collection methods assess extent occurrence seafood. In this context, natural should investigated. A multidisciplinary approach issue recognizes interrelationship connection environmental health with animals humans used, leading application strategies reduce pollution through control sources development remediation technologies.

Microplastic polyamide toxicity: Neurotoxicity, stress indicators and immune responses in crucian carp, Carassius carassius

Ecotoxicology and Environmental Safety, Год журнала: 2023, Номер 265, С. 115469 - 115469

Опубликована: Сен. 22, 2023

This study aimed to determine the toxicity standard and potential risks effects of polyamide (PA) exposure on neurotoxicity, stress indicators, immune responses in juvenile crucian carp Carassius carassius. Numerous microplastics (MPs) exists within aquatic environments, leading diverse detrimental impacts organisms. The C. carassius (mean weight, 23.7 ± 1.6 g; mean length, 13.9 1.4 cm) were exposed PA concentrations 0, 4, 8, 16, 32 64 mg/L for 2 weeks. Among neurotransmitters, acetylcholinesterase (AChE) activity liver, gill, intestine was significantly inhibited by exposure. Stress indicators such as cortisol heat shock protein 70 (HSP70) increased, while lysozyme immunoglobulin M (IgM) decreased. Our demonstrates toxic MP carp's responses.

Screening of Microplastics in Aquaculture Systems (Fish, Mussel, and Water Samples) by FTIR, Scanning Electron Microscopy–Energy Dispersive Spectroscopy and Micro-Raman Spectroscopies

Applied Sciences, Год журнала: 2023, Номер 13(17), С. 9705 - 9705

In the last decade, plastic waste has become one of main threats to marine ecosystems and their biodiversity due its abundance increased persistence. Microplastics can be classified as either primary, i.e., fabricated for commercial use, or secondary, resulting from fragmentation/weathering processes larger pieces in environment. general, microplastics are detected a number aquatic organisms (e.g., fish, bivalves, mollusks, etc.) with alarming effects on health. Therefore, present work focuses detection identification fish species (Dicentrarchus labrax, Sparus aurata) mussels (Mytilus galloprovincialis) aquaculture systems since these largely commercially available consumption. addition, seawater was also screened types polymers well aging. The experimental protocol biota samples contains digestion step using Fenton’s reagent (0.05 M FeSO4⋅7H2O 30% H2O2 at volume ratio 1:1) remove organic material followed by filtration density separation where sample mixed saturated ZnCl2 solution separate microplastic particles heavier material. For (sampled net sampler), only sieving stainless steel sieves silica filters applied. Detection polymeric composition achieved through combined use micro-Raman analysis, Attenuated Total Reflectance–Fourier Transform Infrared spectroscopy, Scanning Electron Microscopy tandem Energy Dispersive X-ray spectroscopy. Microplastic 16 ± 1.7 items/individual 22 2.1 sea bass, 40 3.9 bream, polyethylene (74.4%) being most polymer type, while polyethylene-co-vinyl acetate (65%), polyvinyl-butyral (36.8%), polyvinyl alcohol (20%), polybutyl methacrylate (15.8%) were lesser extent. isolated films (30%), fragments fibers some them derived foams (20%). Also, seawater-recovered microplastics, relatively high degree oxidation (carbonyl index > 0.31) observed, which further confirmed results Finally, images showed various morphological characteristics (cracks, cavities, burrs) surfaces attributed environmental exposure.

The increased awareness about possible health effects arising from micro- and nanoplastics (MNPs) pollution is driving a huge amount of studies. Many international efforts are in place to better understand characterize the hazard MNPs present environment. literature search was performed according Preferred Reporting Items for Systematic Reviews Meta-Analyses (PRISMA) methodology two different databases (PubMed Embase). selection articles carried out blind, screening titles abstracts inclusion exclusion criteria. In general, these studies rely on already use assessing nanomaterials particles concern. However, only limited number have so far directly measured human exposure examined relationship between such its impact health. This review aims provide an overview current state research biomarkers oxidative stress, inflammation, genotoxicity that been explored relation exposure, using human, cellular, animal, plant models. Both in-vitro in-vivo models suggest level stress inflammation as main mechanism action (MOA) leading adverse chronic immunotoxicity genotoxicity. With identification biological endpoints, representing critical key initiating events (KIEs) towards adaptive or outcomes, it identify panel surrogate be applied validated especially occupational settings, where higher levels may occur.
