The Effects Of Micro- And Nanoplastics Are Not Yet Fully Understood
Summary
Micro- and nanoplastics are now ubiquitous in marine and terrestrial environments, yet standardized methods for sampling, chemical analysis, and regulatory limits remain absent, leaving scientists unable to fully characterize exposure levels or set safe thresholds. Without agreed protocols, risk assessments for wildlife and human health are unreliable, hampering evidence-based policy to curb plastic pollution.
Standard methodologies for their sampling, analysis, and regulation remain insufficient Owing to their versatility, plastics have almost limitless applications. Most plastics, however, are used in packaging and, therefore, consigned for immediate discard. These accumulate in the environment, and it is estimated that each minute, a garbage truck of plastic is dumped in the ocean. Although
