A low-cost methodology for estimating beach-stranded plastic pellets using drone-based aerial photographs and marine natural wracks as proxy

Collection, Detection, Identification, and Estimation of Microplastic from the Marine Environment: An Overview

AI summary · Read the abstract

Researchers reviewed techniques for collecting, detecting, and identifying microplastics in marine environments, highlighting the exponential growth of plastic pollution across all ocean zones and the health risks posed to marine organisms by these pervasive sub-5mm contaminants.

Toward a Method of Assessing Microplastic Accumulation in Beach Sand Deposits

AI summary · Read the abstract

Researchers tested four saline density separation solutions to develop a low-cost method for extracting and quantifying microplastics from beach sand, achieving recovery rates of 61–78% for coarse particles across six plastic types. Standardizing affordable extraction methods is a critical step toward generating comparable microplastic concentration data across global beach environments.

Multi-scale assessment of marine plastic pollution on the Algerian western coast: New indices and dual-mesh approach

From Land to Sea: Model for the Documentation of Land-Sourced Plastic Litter

AI summary · Read the abstract

A systematic model was developed to document and quantify land-sourced plastic litter pathways from point of disposal to ocean entry, providing a structured framework for tracking how improperly discarded plastic on land ultimately contributes to marine microplastic pollution. Better documentation of land-to-sea transport routes is essential for targeting waste management interventions at the highest-impact points in the plastic pollution pipeline.
