Summary

Researchers conducted an integrative assessment of microplastic contamination across all marine compartments of the Bay of Marseille - from surface waters to depth - addressing the 'Missing Plastic Paradox' caused by studies that focus only on surface measurements. The study combined surface sampling with water column and sediment analysis to produce a comprehensive estimate of microplastic stocks in the Mediterranean's Gulf of Lion.

Study Type Environmental

Microplastics (MP) contaminate all marine compartments, from the surface to the deep sea. However, accurately estimating MP stock in marine environments overall remains challenging, as the water column and the sediment remain largely understudied. Most studies focus only on MP present at the surface, leading to an observational bias that could contribute to the M̈issing Plastic Paradox.̈ The Mediterranean Sea is assumed to concentrate about 7 Also see: https://micro2024.sciencesconf.org/564621/document
