This study aimed to implement a targeted multiple reaction monitoring (MRM) screening strategy using liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) for the initial detection of 165 compounds of emerging concern (CECs) in water, sediment, and fish samples. Following the screening, confirmatory and quantitative analyses were conducted using analytical standards for the detected compounds. Qualitative results were confirmed using high-resolution mass spectrometry (HRMS) for those CECs without available standards.

Technological advances have led to a proportional increase in the deposition of contaminants across various environmental compartments, including water sources. Heavy metals, also known as potentially toxic metals, are of particular concern due to their significant harmful impacts on environmental and human health. Among the available methods for mitigating the threat of these metals in water, solar radiation-based technologies stand out for their cleanliness, cost-effectiveness, and efficiency in removing or reducing the toxicity of heavy metals.

Article Synopsis
  • - Sulfite is used to prevent discoloration in shrimp but can cause health issues for sensitive individuals, necessitating monitoring of its levels.
  • - A new, efficient method was developed for extracting and quantifying sulfite using automated pressurized liquid extraction (PLE) and capillary zone electrophoresis, addressing the challenges of stabilization and analysis.
  • - The new method showed high precision and stability, with recovery rates between 97%-99% and detection limits suitable for practical applications in shrimp processing.
