Randomized trial analyzes shipyard contaminants in marine sediments, suggesting threats to benthic ecosystems.

This study aims to characterize the chemical footprint of shipyards by identifying and quantifying contaminants in marine sediments.
Utilized high-resolution mass spectrometry for non-targeted analysis of marine sediments in Gohyeon Bay, South Korea.
Identified shipyard-derived chemicals through suspect screening and hierarchical clustering of spatial distribution patterns.
Conducted ecological risk assessment based on risk quotients of identified contaminants.
Detected 412 compounds with functional uses, identifying 12 as suspect shipyard-related chemicals.
Isolated nine diagnostic contaminants with concentration hotspots adjacent to shipyard facilities.
Identified five chemicals posing high ecological risk (RQ > 1) to benthic organisms.

Islam et al. (2026) studied this question.
