Résumé

Efficient and resilient techniques for handling samples are essential for detecting pharmaceutical compounds in the environment. Tis study explores a method for preserving water samples during transport before quantitative analysis. Te study investigates the stability of 17α-ethynylestradiol (EE2), acetaminophen (ACM), oxytetracycline (OTC), sulfamethoxazole (SMX), and trimethoprim (TMP) after preconcentration within solid-phase extraction (SPE) cartridges. Trough various experiments involving diferent holding times and storage temperatures, it was determined that four pharmaceutical compounds remained stable when stored for a month at 4 °C and for six months when stored at-18 °C in darkness. Storing these compounds in SPE cartridges at-18 °C seemed efective in preserving them for extended periods. In addition, ACM, TMP, OTC, EE2, and SMX remained stable for three days at room temperature. Tese fndings establish guidelines for appropriate storage and handling practices of pharmaceutical compounds preconcentrated from aqueous environmental samples using SPE.
