Microplastics in fecal samples of mammalian terrestrial wildlife in Hong Kong
AI summary Read the abstract
Researchers assessed microplastic presence and abundance in fecal samples from mammalian wildlife in Hong Kong country parks, examining how animals living near human-modified habitats accumulate plastic particles. Microplastics were detected in wildlife feces, with types reflecting human-associated plastic waste from nearby populated areas.
Despite its high population density, Hong Kong continues to support a diversity of wildlife within its adjacent country parks. Wildlife residing in Hong Kong's country parks often experience interaction with humans, leading to alterations to their diet. This study aims to assess the presence and abundance of microplastics (MPs) in feces of various terrestrial mammals inhabiting six country parks in Hong Kong, serving as an indicator of plastic ingestion. The study includes five species: macaques, boars, porcupine, buffalo and cattle. Samples were collected in the summer of 2022, one to three sampling sites selected for each animal species. Sample treatment included two digestion processes with Fenton's reagent and 10 Also see: https://micro2024.sciencesconf.org/559479/document

Researchers analyzed fecal samples from seven mammalian wildlife species in Hong Kong country parks to assess microplastic ingestion. All species tested positive for microplastics, with fiber morphotypes dominating, suggesting that urban wildlife is routinely ingesting plastic particles.
A comparative analysis of microplastics in feces of terrestrial mammalian wildlife around Hong Kong
AI summary Read the abstract
Researchers compared microplastic contamination in the feces of five wild mammal species living near urban areas in Hong Kong, including buffalo, wild boar, and macaques. They found microplastics in all species and at all sites, with buffalo showing the highest concentrations and macaques showing the widest range of contamination levels. The study suggests that wildlife living near human settlements faces significant microplastic exposure through food and environmental contact.

Researchers examined microplastic accumulation in terrestrial wildlife carcasses and fecal samples from inside and outside protected areas in western Thailand. Microplastics were detected in multiple species regardless of protected status, suggesting wide environmental distribution.
Microplastics contamination in terrestrial wildlife: the study in carcasses and feces of vertebrate species in western Thailand
AI summary Read the abstract
Researchers examined microplastic accumulation in terrestrial wildlife carcasses and fecal samples from protected and non-protected areas of western Thailand, finding contamination in multiple species. The presence of microplastics in wildlife from protected areas highlights the inability of conservation boundaries to shield fauna from pervasive plastic pollution.
Using feces to indicate plastic pollution in terrestrial vertebrate species in western Thailand
AI summary Read the abstract
Researchers examined feces from 12 wild animal species in western Thailand and found microplastics in over 40% of samples across eight species, including elephants, deer, and wild boar. The amount of microplastics found was linked to human activity near the animals' habitats. This demonstrates that microplastic contamination has reached even terrestrial wildlife in protected areas, entering the food chain far from obvious pollution sources.
