SOP for Determination of POPs

The method’s QA/QC process begins with sample collection (water, sediment, and biota). The collection techniques utilized must yield a representative sample that remains unchanged throughout the collection. Silica rubber, low-density polyethylene (LDPE) bags, and semipermeable membrane device (SPMD) are powerful sampling tools that have recently been created and employed in aquatic environments. Extraction and fractionation techniques are presented. The most commonly used equipment for determining POPs is high-performance liquid chromatography (HPLC) and gas chromatography. The accuracy and precision of the procedures described should be verified.
