“…Their sources have been attributed to direct ingestion or trophic transfer (Nelms et al, 2018;Waring et al, 2018). For low trophic level aquatic animals, ingestion of MPs can reduce energy reserves, feeding capacity, and reproductive outputs, and damage physiological and immune systems (Nabi et al, 2022). For the aquatic mammals in the apex position of the trophic web, although MPs do not cause physical obstacles through entanglement, they can act as carriers of pollutants and toxins, which, combined with biomagnification and bioaccumulation, negatively affect health (Holmes et al, 2012;Avio et al, 2015).…”

“…For the aquatic mammals in the apex position of the trophic web, although MPs do not cause physical obstacles through entanglement, they can act as carriers of pollutants and toxins, which, combined with biomagnification and bioaccumulation, negatively affect health (Holmes et al, 2012;Avio et al, 2015). Bioaccumulated chemical pollutants transferred by MPs (e.g., heavy metals, pesticides, biocides) can also cause endocrinal gland cancer in aquatic mammals, and MPs-linked pathogens also increase the risk of infectious diseases and mortality (Lauretta et al, 2019;Nabi et al, 2022). Otherwise, micro or nano-plastics are also likely to cross the cell membranes and enter the circulatory system, and then accumulate in organs (such as brain, liver, kidney, placenta) with other pollutants (Prietl et al, 2014;Banerjee and Shelver, 2021;Nabi et al, 2022).…”

Microplastics (MPs) pose serious threats to various marine organisms, including many threatened apex predators such as cetaceans. However, information on microplastic contamination in cetaceans from Asian waters is limited. Based on the analysis of Fourier transform infrared spectroscopy (FTIR), we reported MPs from finless porpoise intestinal samples and from their habitats along the Fujian coast of the East China Sea. MPs proved to be ubiquitous in both intestinal and habitat water samples. Most intestinal MPs were fibers (86.90%), transparent (51.19%), small sizes (<1.0 mm, 77.38%), and composed of polyamide (41.67%) or polyethylene terephthalate (45.24%). Seawater MPs were predominantly fibers (90.25%), transparent (82.45%), < 1.0 mm (83.76%) and composed of polypropylene (67.32%). Concentrations of MPs in coastal waters were greater than those in offshore waters. The concentration and composition of fibrous MPs indicate a likely textile industry origin. A recommendation is made to further assess the risks of MPs consumption in threatened species and develop scientific protection and management strategies.

“…Aquatic mammals have been reported to ingest various polymers, including polyether-sulphone, nylon, cotton, polyester, polyethylene, polypropylene, and ethylene-propylene (Nelms et al 2019 ; Meaza et al 2021 ). Microplastics can also contribute to the bioaccumulation of pollutants in aquatic mammals due to their hydrophobic surface and larger surface area-to-volume ratio (Nabi et al 2022 ; Wang et al 2020b ; Verla et al 2019 ). Besides, in vivo studies using marine organisms have shown that microplastics have significant toxic effects on animals through different exposure routes, such as intravenous, subcutaneous, intraperitoneal, oral, and skin exposure.…”

Microplastic pollution is becoming a major issue for human health due to the recent discovery of microplastics in most ecosystems. Here, we review the sources, formation, occurrence, toxicity and remediation methods of microplastics. We distinguish ocean-based and land-based sources of microplastics. Microplastics have been found in biological samples such as faeces, sputum, saliva, blood and placenta. Cancer, intestinal, pulmonary, cardiovascular, infectious and inflammatory diseases are induced or mediated by microplastics. Microplastic exposure during pregnancy and maternal period is also discussed. Remediation methods include coagulation, membrane bioreactors, sand filtration, adsorption, photocatalytic degradation, electrocoagulation and magnetic separation. Control strategies comprise reducing plastic usage, behavioural change, and using biodegradable plastics. Global plastic production has risen dramatically over the past 70 years to reach 359 million tonnes. China is the world's top producer, contributing 17.5% to global production, while Turkey generates the most plastic waste in the Mediterranean region, at 144 tonnes per day. Microplastics comprise 75% of marine waste, with land-based sources responsible for 80–90% of pollution, while ocean-based sources account for only 10–20%. Microplastics induce toxic effects on humans and animals, such as cytotoxicity, immune response, oxidative stress, barrier attributes, and genotoxicity, even at minimal dosages of 10 μg/mL. Ingestion of microplastics by marine animals results in alterations in gastrointestinal tract physiology, immune system depression, oxidative stress, cytotoxicity, differential gene expression, and growth inhibition. Furthermore, bioaccumulation of microplastics in the tissues of aquatic organisms can have adverse effects on the aquatic ecosystem, with potential transmission of microplastics to humans and birds. Changing individual behaviours and governmental actions, such as implementing bans, taxes, or pricing on plastic carrier bags, has significantly reduced plastic consumption to 8–85% in various countries worldwide. The microplastic minimisation approach follows an upside-down pyramid, starting with prevention, followed by reducing, reusing, recycling, recovering, and ending with disposal as the least preferable option.

“…The escalating issue of nanoparticle and microplastic pollution in water, as discussed earlier, raises concerns about the potential impact on aquatic organisms. Research indicates that nanomaterials and microplastics primarily pose risks to the intestinal system and gills of these organisms (Alak, Uçar et al 2022, Nabi, Ahmad et al 2022. While studies on the effects of micronano pollutants (MNPs) on fish reproductive systems are still ongoing, there is growing evidence indicating potential impacts.…”

Nanoparticles (NPs) are small size molecules. It is divided into organic and inorganic. Organic NPs have many clinical uses, from inoculation to homeostasis, long-term storage and delivery to the system, and absorption of topically used drugs into the skin. Inorganic NPs can be used in intraoperative lymphatic scanning, tumors, and anemia treatments. NPs have a favorable effect on sperm motility, kinematic parameters or membrane integrity rates, they can also be used as antibacterial, antiviral and antifungal in genital organ diseases. There are many studies in which the addition of NPs can be beneficial or harmful to sperm. Researchers have stated that it may be beneficial or cytotoxic depending on in vivo (such as airway, skin or injection) or in vitro use. It has been reported that NPs have positive effects on motility, kinematic parameters, plasma membrane integrity, DNA damage and acrosomal integrity and can be used as an antioxidant. In addition, it has been reported that it can be used in sexsorting, bioimaging and nanopurification, and that more studies on NPs will increase in the coming years.
