Exposure to microplastics affects fatty acid composition in the Japanese quail depending on sex and particle size. | LitMetric

AI Article Synopsis

Article Abstract

Plastic ingestion in birds is a widespread phenomenon of increasing concern. However, little is known about how exposure to microplastics (MP) affects the health of birds. In other organisms, MP exposure alters lipid metabolism and composition. If also true in birds, this could affect their fitness, especially since birds heavily rely on lipids during migration and egg production. Therefore, the aim of this study was to determine if ingestion of MP (polypropylene and polyethylene collected in nature) in two size ranges, large (3 mm) and small (<125 μm), affects lipid metabolism in the Japanese quail (Coturnix japonica). We orally exposed 55 one-week-old quail during 5 weeks to a total of 600 mg of MP in sizes of either large, small, or a mixture of both. After the exposure period, females fed small MP had higher liver masses compared to control females (on average ± SD, 8.95 ± 2.3 g vs. 6.34 ± 1.0 g), while liver lipid content did not differ in either males or females. The levels of monounsaturated fatty acids were lower in females exposed to large MP and the mixture of both MP sizes compared to controls. Females exposed to MP also had different levels of oleic- (18:1) and palmitoleic (16:1) acid compared to controls dependent on MP size. Exposure to small MP increased levels of palmitic- (16:0) and palmitoleic (16:1) acid in both males and females suggesting a possible increase in de novo fatty acid synthesis. Taken together, our results point towards a sex-specific sensitivity to MP as well as size-dependent MP effects on lipid metabolism in birds. Disruption of fatty acid composition could affect important life stages in female birds, such as migration and egg-laying. We stress the importance of further research focused on determining the mechanisms of action of MP on lipid metabolism.

Toxicity effects of microplastics individually and in combination with Aeromonas hydrophila on freshwater crayfish (Astacus leptodactylous).

Environ Sci Pollut Res Int

December 2024

Division of Aquatic Animal Health & Diseases, Department of Clinical Sciences, School of Veterinary Medicine, Shiraz University, Shiraz, Iran.

Opportunistic pathogens, such as Aeromonas hydrophila, can cause damage to freshwater crayfish (Astacus leptodactylous) in some situations. In addition to direct damage to the body, microplastics (MPs) can also be responsible for transmitting pathogens to the animal. Accordingly, this research was prepared to investigate the effects of MP on the damage caused by A.

Department of Environment and Health, Istituto Superiore di Sanità, Rome, Italy. Electronic address:

This review figures out the overall status on the presence of microplastics (MPs) and nanoplastics (NPs) in food and their bioaccumulation in animal and human tissues, providing critical insights into possible human health impacts. Data are discussed on both in-vivo and ex-vivo animal and human studies, and the role of physicochemical properties in determining the biological fate and toxicological effects of MPs and NPs. Particular attention is given to dietary exposure assessments, specifically evaluating daily intake through the consumption of contaminated food items.

Microplastics Aggravate the Adverse Effects of Methylmercury than Inorganic Mercury on Zebrafish (Danio rerio).

The potential health risks of microplastics (MPs) and their combined exposure with heavy metals such as mercury (Hg) in aquatic environment are increasingly concerned recently. In this work, zebrafish embryos were exposed to different levels of polystyrene microplastics (PS-MPs, ∼0.1 μm) coupled with Hg(II) or/and MeHg at 20 μg/L, to investigate the tissue biodistribution and accumulation of PS-MPs and Hg species, and their interaction, as well as embryo toxicity, oxidative stress and metabolic profiles.

Plastic pollution and marine mussels: Unravelling disparities in research efforts, biological effects and influences of global warming.

The ever-growing contamination of the environment by plastics is a major scientific and societal concern. Specifically, the study of microplastics (1 μm to 5 mm), nanoplastics (< 1 μm), and their leachates is a critical research area as they have the potential to cause detrimental effects, especially when they impact key ecological species. Marine mussels, as ecosystem engineers and filter feeders, are particularly vulnerable to this type of pollution.
