Abstract Plastic pollution constitutes one of the major environmental problems our time, and in recent years, it has emerged as a significant threat to environment various organisms, including bird species. In this context, study, which provides first data Türkiye, aimed determine level microplastic (MP) 12 species (Eurasian buzzard; short-toed snake-eagle; white stork; northern long-eared owl; common barn-owl; ruddy shelduck; Eurasian eagle-owl; scarlet macaw; pheasant; Indian peafowl; kestrel; gray parrot). The results indicate that MPs were detected 50% specimens (n = 20), with an average MP/item per individual. With three individual, snake-eagle was found be highest MP accumulation. Fibers (range: 51–534 µm) most type plastic gastrointestinal tract birds, ethylene vinyl acetate navy blue being polymer color, respectively. It also abundance increased weight specimens, contributing hypothesis there is correlation between size/weight animals levels These findings highlight impact on birdlife need for further monitoring assess ecological pollution.

Microplastic accumulation in snake-eyed lizard (Ophisops elegans Menetries, 1832) after long-term monitoring: habitats matter, not years

Microplastics (MPs) have become pervasive environmental pollutants with significant impacts on ecosystems, particularly aquatic environments. As these particles infiltrate various habitats, they are ingested by a wide range of organisms, from plankton to large marine mammals. The ingestion MPs disrupts the food web, causing physical and chemical harm animals at multiple trophic levels. Here, we studied accumulation in gastrointestinal tracts (GITs) terrestrial lizard species after long-term monitoring using museum specimens collection Fauna Flora Research Application Center Dokuz Eylül University decades ago. These samples were 1986 2013, but not consecutive years. GITs 300 individuals analyzed detected only 25 individuals. In individuals, most dominant form microplastic was fiber. highest number 2001, followed 1995. It is thought that this caused human activities lizard's environment it enters web indirectly because lives areas high interaction. Overall, study shows been present past, entering species, can inherently transfer other living things. understood will pose threats biodiversity ecosystem health as transferred through chain.

Plastic pollution is a widespread and growing concern due to its transformation into microplastics (MPs), which can harm organisms ecosystems. This study, aimed identify plastic in the feces of terrestrial vertebrates using convenience sampling both inside outside protected areas Western Thailand. We hypothesized that MPs are likely be detectable all vertebrate species, primarily form small black fragments. predicted varying quantities same species across different areas. Furthermore, we expected factors indicating human presence, landscape characteristics, scat weight, MP abundance water, soils, sediments would influence presence plastics feces. Among 12 studied, potential were found 41.11% 90 samples, totaling 83 pieces eight including Asian elephant ( Elephas maximus ), Eld’s deer Rucervus eldii Dhole Cuon alpinus Gaur Bos gaurus Sambar Rusa unicolor Wild boar Sus scrofa Northern red muntjac Muntiacus vaginalis Butterfly lizard Leiolepis belliana ).

Birds as Bioindicators: Revealing the Widespread Impact of Microplastics

Birds, Journal Year: 2025, Volume and Issue: 6(1), P. 10 - 10

Published: Feb. 11, 2025

The global crisis of plastic pollution, particularly involving microplastics (MPs) and nanoplastics (NPs), has profound ecological implications. Birds, serving as bioindicators, are especially susceptible to these pollutants. This systematic review synthesizes the current research on presence, distribution, impact MPs NPs avian species, alongside advancements in detection methodologies. have been identified over 200 bird species across 46 families, encompassing several ecosystems, from Antarctica Labrador, including Australia, China, South Europe. Seabirds such penguins, gulls, shearwaters exhibit a high burden tissues feces due fishing debris, while terrestrial face contamination urban agricultural sources. Depending their composition, can cause gastrointestinal damage, oxidative stress, bioaccumulation toxic chemicals, polyethylene polypropylene. However, challenges persist methodological inconsistencies, though advances spectroscopy flow cytometry offer improved accuracy. Addressing this pollution is vital for conservation ecosystem health, requiring international collaboration standardized protocols.

Tire-Road-Wear Particles and Glass Beads in the Gizzard of the Endangered Terrestrial Bird, Okinawa Rail (Hypotaenidia okinawae)

Environmental Science & Technology, Journal Year: 2025, Volume and Issue: unknown

This study analyzed microplastics and glass beads (GBs; an indicator of traffic-derived particulate contamination) in 42 gizzards endangered terrestrial bird, the Okinawa rail (Hypotaenidia okinawae). Black rubber fragments (BRs) were found 57% specimens (1–184 items/individuals), GBs 48% (1–32 items/ind.). FTIR identified rubbers as same materials used tire tread. A significant positive correlation was between abundances BRs (p < 0.01), suggesting source exposure pathway. Large quantities BRs, namely tire-road-wear particles (TRWPs), also environmental samples (road dust, roadside soil, side-ditch sediment) diet organisms (earthworm, millipede, snail). The characteristics these (appearance, material type, size distribution) consistent gizzard contents samples. concentration ratio similar to that sediment organisms, especially earthworms. These results indicate rails are exposed contaminants including TRWPs via ground-feeding along roadside. To our knowledge, this is first evidence bird species.

Because of their diversity, microplastics (MPs), which are synthetic particles smaller than 5 mm, highly bioavailable and widely distributed. The prevalence in aquatic habitats has been extensively studied but less is known about presence terrestrial environments biota. This study examined MP intake utilizing gastrointestinal tracts (GITs), with a particular focus on the Turkish worm lizard (Blanus strauchi). Suspected discovered GITs were removed, measured, characterized based size, shape, color, polymer type order to evaluate ingestion. Out 118 samples analyzed, 29 specimens (or 24.57%) had microplastic particlesMP length did not significantly correlate snout–vent (SVL) weight. These correlations tested determine whether size or weight Blanus strauchi influenced amount MPs found within GITs. Also, consumption by year sampling. All identified as fibers through FT-IR spectroscopy analysis. most common was polyethylene terephthalate (PET). often detected color blue, mean lengths ranging from 133 µm 2929 µm. It demonstrated that lizards inhabiting soil sheltering under stones bushy areas sparse vegetation consume MPs. Predation regarded be likely way infiltrate food webs.
