Marine microplastics are a global environmental issue, and understanding their distributions in estuaries coastal areas is critical prerequisite for the effective sustainable management of microplastic pollution. Owing to lack methods that exist quantifying content, characterizing distribution difficult. The mass concentration an objective indicator reflects distribution. Therefore, formula calculating proposed through parameters number concentration, size, mesh addition proportions particles with different sizes shapes. On basis large amount existing measured data, concentrations calculated. It can be concluded polypropylene (PP; 72%) polyethylene (PE; 67%) most abundant ocean. Additionally, marine more common (102–103 mg/L) than open sea (0–10 mg/L). maximum surface water approximately 8.0 g/L. Moreover, pollution has significantly increased surrounding sewage treatment plants aquaculture farms.

High concentrations of microplastics (MPs) have been documented in the deep-sea surface sediments Arctic Ocean.However, studies investigating their high-resolution vertical distribution from European waters to remain limited.This study examines MPs five sediment cores Norwegian Coastal Current (NCC), encompassing water-sediment interface and layers up 19 cm depth.Advanced analytical methods for MP identification down 11 μm size were combined with radiometric dating lithology observations.MPs present across all cores, including predating introduction plastics, exhibiting significant variation (54-12,491 kg -1 ).The smallest class (11 μm) predominated most (34-100%).A total 18 different polymer types identified layers, diversity depth correlations varying widely between stations.Our findings suggest that differences seafloor topography impact anthropogenic activities (e.g., fishing) lead environmental conditions at sampling sites, influencing MPs.This challenges reliability using parameters predict accumulation zones questions use as indicators Anthropocene.
