Microplastics (MPs), less than 5 mm in length, have become a major environmental issue due to their hazardous physical and chemical properties. The research investigated 54 sediment samples collected from three different zones of the beaches, namely wrack line, beach face, swash zone. This study aims enumerate number polymeric variety microplastics found sediments coastal islands Bangladesh, including Sandwip, Kutubdia, Saint Martin's Island northeastern Bay Bengal.

Microplastics pose a significant environmental threat, and understanding their sources generation mechanisms is crucial for mitigation efforts. This study investigates the effects of ultraviolet intensity, temperature, relative humidity on degradation polyethylene terephthalate (PET) plastics subsequent formation microplastic particles. PET samples were exposed to (UV) radiation under various conditions using SPHERE (Simulated Photodegradation via High Energy Radiant Exposure) accelerated weathering device at National Institute Standards Technology (NIST). Attenuated total reflectance–Fourier transform infrared spectroscopy (ATR-FTIR) laser confocal scanning microscopy (LSCM)/atomic force (AFM) employed characterize chemical morphological changes weathered surfaces. study’s findings reveal that temperature significantly influence rate photodegradation characteristics generated microplastics. Higher temperatures increased process, leading higher abundance However, larger particles observed due aggregation. These results underscore importance considering factors when assessing fate transport microplastics in environment. Developing strategies reduce plastic pollution mitigate essential protecting ecosystems human health.

The Yangtze River Basin (YRB) is an important source of marine microplastics (MPs). However, unscientific research methods in previous studies have led to inaccurate estimates the occurrence and ecologic risk MPs. This study aimed comprehensively assess distribution ecological risks MPs YRB, through investigating full-size surface waters YRB over 3 years. Size Effect was developed based on impact size MP-carried pollutants human health, combined with multiple evaluate potential average MP abundance 8797 ± 12,281 items/m3, dominated by polypropylene fragments. small (<0.3 mm; 92.52%) were driving factor spatial heterogeneity. Interestingly, Three Gorges Dam significantly altered weakened transportation. Agricultural activities, wastewater treatment plants, atmospheric deposition main sources YRB. Multiple assessment indicated that at middle–low level. addresses <0.05 mm provides insights for assessment, serves as a reference sustainable management.
