ABSTRACT

using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The target compounds included diuron, irgarol 1051, and prometryn, which are prevalent in marine environments owing to their extensive use in antifouling coatings and agriculture. The analytical procedure involves solid-phase extraction (SPE) using HLB cartridges followed by LC-MS/MS analysis for precise quantification. The method exhibits high recovery rates for diuron (101%± 1.25), irgarol 1051 (94.7% ± 2.08), and prometryn (93.7% ± 3.06). Seawater samples from 30 coastal sites in Korea were analyzed. Irgarol 1051 was not detected, whereas diuron was consistently detected across all sites, with concentrations from 0.68 to 11.3 ng/L, and prometryn was present at levels between 0.12 and 7.06 ng/L. The highest diuron and prometryn concentrations were recorded along the southeastern and western coasts, respectively. These findings underscore the critical need for continuous monitoring and regulations to manage these contaminants in marine ecosystems, thereby safeguarding ecological integrity and public health. This study establishes a robust analytical framework for the comprehensive assessment of multiple marine contaminants.
