Abstract
This study systematically investigated the abundance, characteristics, and spatial and temporal variations of microplastics (MPs) in the lower Chao Phraya River, Thailand, during the COVID-19 pandemic. The study revealed an average MP abundance of 8.3 ± 5.8 particles/m3, mainly composed of polyethylene (PE) and polypropylene (PP) with fibers and fragments being the predominant shapes. Spatially, MP concentrations exhibited a notable increase downstream, particularly in highly urbanized areas. Temporally, MP concentrations showed slight elevation during the wet season, with clear seasonal variations in MP size and shape distributions attributed to the influence of urban storm runoff. Despite expectations of heightened MP pollution due to the COVID-19 pandemic, the study suggests a potential reduction in MP abundance, likely attributed to decreased socio-economic activities. Nonetheless, the long-term effects remain uncertain, underscoring the imperative for continuous monitoring and effective environmental management strategies.
