Microplastics are emerging contaminants increasingly found in aquatic ecosystems. Their persistence and fragmentation into smaller particles make them a significant concern for freshwater habitats, though their ecological impact is not fully understood. This study examined microplastics in vernal ponds, ephemeral aquatic habitats in northeastern U.S. forests. Seven ponds in Central Pennsylvania were sampled for microplastic composition, abundance, and correlations with environmental factors. Microplastic fragments were found in all sites, with the highest abundance near residential areas. These results highlight the need for further research on microplastic accumulation in these ecosystems.
