Key findings are:
📌 OPE show higher concentrations in equatorial waters and decrease toward the poles.
📌 The biological pump plays a crucial role in sinking OPEs from surface waters.
📌 OPE trends at 2000m depth mirror those at the surface, revealing long-term accumulation in deep waters.
📌 OPE show higher concentrations in equatorial waters and decrease toward the poles.
📌 The biological pump plays a crucial role in sinking OPEs from surface waters.
📌 OPE trends at 2000m depth mirror those at the surface, revealing long-term accumulation in deep waters.

In this study, we demonstrated a comprehensive workflow combining direct infusion (DI) and liquid chromatography (LC) high-resolution mass spectrometry (HRMS) to characterize dissolved organic matter (DOM) at both molecular and structural levels across different water sources.

Microbial activity was closely linked to OPE depletion, showing that bacteria play a key role in breaking down these pollutants. Our findings highlight how environmental conditions shape pollutant biodegradation in the ocean!

In this work, we investigated how marine microbes break down organophosphate esters (OPEs) in the Atlantic and Southern Oceans. We found that hydrophobic OPEs degraded significantly in the Atlantic, while cold temperatures in the Southern Ocean slowed the process.
