AI Article Synopsis
- Water samples from ten German Baltic estuaries were tested for glyphosate and its primary metabolite AMPA in 2012, revealing widespread contamination.
- An optimized LC-MS/MS analytical method was used, showing glyphosate concentrations ranged from 28 to 1690 ng/L, while AMPA ranged from 45 to 4156 ng/L, with significant variations over time and space.
- The findings indicate that both contaminants are transported to the Baltic Sea, highlighting the need for thorough assessments of their environmental impact.
Article Abstract
Water samples from ten German Baltic estuaries were collected in 2012 in order to study the presence of the herbicide glyphosate, its primary metabolite AMPA and their potential transport to the marine environment. For the analyses an LC-MS/MS based analytical method after derivatization with FMOC-Cl was optimized and validated for marine water samples. All investigated estuarine stations were contaminated with AMPA and nine of them also with glyphosate. Concentration ranges observed were 28 to 1690ng/L and 45 to 4156ng/L for glyphosate and AMPA, respectively with strong spatial and temporal fluctuations. Both contaminants were found at inbound sampling sites in the stream Muehlenfliess and concentrations decreased along the salinity gradient to the estuaries of the Baltic Sea. The data obtained in this study clearly depict the transport of glyphosate and AMPA to the Baltic Sea. Hence, detailed fate and risk assessment for both contaminants in marine environments are required.
