A Reliable and Cost-Effective Method for Determination of Endocrine-Disrupting Compounds in Coastal Waters, Suspended Particulate Matter, and Sediments by Ultrafast Liquid Chromatography Coupled to Photodiode Array and Fluorescence Detectors

Analytical methods for determining 14 endocrine-disrupting compounds (EDCs) in coastal waters, suspended particles, and sediment samples were successfully performed by ultrafast liquid chromatography with photodiode array fluorescence detections (UFLC-PDA-FLD). Solid‑phase extraction (SPE) ultrasound-assisted (USE) used sample preparation. Two chromatographic have been developed. An isocratic separation method was to separate bisphenol A (BPA) steroids another gradient elution phthalates alkylphenols. The detection alkylphenols, BPA, (PDA) phthalates. Limits of (LOD) ranged from 0.41 (4-tert-octylphenol (4tOP)) 63 ng L-1 (dibutylphthalate (DBP)), (4tOP) 63.2 g-1 dried weight (dw) solid (suspended particulate matter (SPM) samples), respectively. Recoveries 52 (diethylphthalate (DEP)) 116% (DBP) water, 54 (DEP) 108% (estrone (E1)) SPM, 62 (4-n-nonylphenol (4nNP)) 117% (4-n-octylphenol (4nOP)) samples. Finally, the minimization reagents energy, proposed applied collected Todos os Santos Bay (BTS), Bahia, Northeastern Brazil.
