Laser direct infrared (LDIR) spectroscopy reveals microplastic sorting and risk evolution in a subtropical river–estuary–coastal continuum: Insights on risk assessment

Key Points

• Microplastic sorting impacts environmental risks along the river-estuary-coastal continuum.
• Analysis of microplastic distribution demonstrates evolving risks over time.
• This observational analysis employs LDIR spectroscopy to assess microplastic interactions.
• Highlighting effective monitoring techniques may support enhanced environmental policies.
