The terrestrial environment is a significant source of anthropogenic debris emissions. While most studies on focus the marine environment, our research delves into effects human activity ingestion by studying carcasses feral pigeons. From January to June 2022, we collected gastrointestinal tracts (GI tracts) 46 pigeon in Taipei, Taiwan's capital city. results revealed that 224 samples were found, with dominant form being fibers (71.9%), which are primarily black (29.9%). Fourier transform infrared spectroscopy (FTIR) main component polyethylene (PE) (20.5%), followed cellulose (19.2%) and various other plastics. This study amount chemical composition GI tract significantly increase increasing activity. These prove pigeons valuable indicators for monitoring pollution urban ecosystems. On hand, past focused analyzing microplastics, but confirmed has high proportion cellulose. Importantly, future should consider potential impacts ecosystems, as this could have implications ecosystem health.

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.
