Summary

This commentary discusses ominous trends in outdoor recreation and their consequences for natural environments, noting that increasing numbers of visitors to natural areas bring with them plastic waste and other contaminants. The piece highlights the growing role of recreational activities in distributing micro- and nano-plastics across natural landscapes.

Micro-nano plastics originating from the prevalent usage of plastics have raised increasingly alarming concerns worldwide. However, there remains a fundamental knowledge gap in nanoplastics because of the lack of effective analytical ...Plastics are now omnipresent in our daily lives. The existence of microplastics (1 µm to 5 mm in length) and possibly even nanoplastics (<1 μm) has recently raised health concerns. In particular, nanoplastics are believed to be more toxic since their ...

Examining sampling protocols for microplastics on recreational trails

This study developed and tested sampling protocols for detecting microplastics on hiking and trail running routes in nature reserves. Microplastics were found on trail surfaces, likely shed from synthetic clothing, footwear, and equipment used by outdoor recreationists. The findings highlight recreational trails as an underappreciated source of microplastic contamination in natural areas.
