Birds and plastic pollution: recent advances

Avian Research, Journal Year: 2021, Volume and Issue: 12(1)

Published: Nov. 2, 2021

Abstract Plastic waste and debris have caused substantial environmental pollution globally in the past decades, they been accumulated hundreds of terrestrial aquatic avian species. Birds are susceptible vulnerable to external environments; therefore, could be used estimate negative effects pollution. In this review, we summarize macroplastics, microplastics, plastic-derived additives plastic-absorbed chemicals on birds. First, macroplastics microplastics accumulate different tissues various birds, suggesting that birds suffer from microplastics-associated contaminants environments. Second, detrimental their derived absorbed individual survival, growth development, reproductive output, physiology, summarized as well known toxicological mechanisms plastics laboratory model mammals. Finally, identify human commensal long-life-span bird species utilized research objectives evaluate plastic burden chronic exposure.

Responses of the gut microbiota to environmental heavy metal pollution in tree sparrow (Passer montanus) nestlings

Ecotoxicology and Environmental Safety, Journal Year: 2023, Volume and Issue: 264, P. 115480 - 115480

Published: Sept. 15, 2023

Gut microbiota plays a critical role in regulating the health and adaptation of wildlife. However, our understanding how exposure to environmental heavy metals influences gut wild birds, particularly during vulnerable sensitive nestling stage, remains limited. In order investigate relationship between microbiota, we analyzed characteristics levels tree sparrow nestlings at different ages (6, 9 12-day-old). The study was conducted two distinct areas: Baiyin (BY), which is heavily contaminated with metals, Liujiaxia (LJX), relatively unpolluted area. Our result reveled decrease diversity increased inter-individual variation among BY. also observed an increase abundance bacterial groups up-regulation metabolic functions associated resistance toxicity Furthermore, identified metal-associated shift relative microbial taxa 12-day-old BY, involving Aeromonadaceae, Ruminococcaceae Pseudomonadaceae. Moreover, significant positive correlation found body condition Bifidobacteriaceae Collectively, findings indicate that susceptible early development. results highlight presence adaptive responses enable them effectively cope metal pollution.

Seaweed polysaccharide relieves hexavalent chromium-induced gut microbial homeostasis

Frontiers in Microbiology, Journal Year: 2023, Volume and Issue: 13

Heavy metals released in the environment pose a huge threat to soil and water quality, food safety public health. Additionally, humans other mammals may also be directly exposed heavy or through chain, which seriously threatens health of animals humans. Chromium, especially hexavalent chromium [Cr (VI)], as common metal, has been shown cause serious environmental pollution well intestinal damage. Thus, increasing research is devoted finding drugs mitigate negative effects exposure. Seaweed polysaccharides have demonstrated many pharmacological effects, but whether it can alleviate gut microbial dysbiosis caused by exposure not characterized. Here, we hypothesized that seaweed could exposure-induced poor mice. Mice Cr polysaccharide treatment group was compulsively receive K2Cr2O7. At end experiment, all mice were euthanized, colon contents collected for DNA sequencing analysis. Results showed administration restore reduction diversity Hexavalent significant changes composition mice, including an increase some pathogenic bacteria decrease beneficial bacteria. However, ameliorate microbiota. In conclusion, this study dysbiosis. Meanwhile, lays foundation application polysaccharides.

Understanding the impact of plastic and its additives on wild species is crucial as their presence in environment increases. Polybrominated diphenyl ethers (PBDEs), once used flame retardants, were restricted due to known toxic effects, but are still detected environment. Naturally occurring methoxylated PBDEs (MeO-BDEs) can result from PBDE transformation may cause similar hazardous effects. Yellow-legged gulls (Larus michahellis, YLG) Audouin's (Ichthyaetus audouinii, AG) highly susceptible additives, distribution, trophic position, behaviour. In this study, we assessed MeO-BDEs uptake different tissues effects physiological reproductive parameters. Findings indicate that, apart annual differences, adult AG accumulated more than YLG a natural breeding habitat (Deserta), while latter had lower levels city Porto. relation chicks, only Deserta showed higher concentrations chicks. Individual analysis each parameter revealed impacts for Deserta, with neurofunction immune system inhibition at MeO-BDE concentrations. For impaired neurofunction, chicks Porto exhibited potential genotoxicity triggered by levels. Overall health activation antioxidant defences compromised adults high values PBDEs, inflammation oxidative stress same species. Fertility parameters significant differences sperm counts though suggesting individuals be able compensate any exposure This study confirms widespread plastic-associated compounds harmful gulls, particularly system, balance fertility, especially MeO-BDEs.
