Ramalhosa, Maria João; Paíga, Paula; Morais, Simone; Sousa, Ana M. M.; Gonçalves, Maria Pilar; Delerue-Matos, Cristina; Oliveira, M. Beatriz P. P.An accurate and sensitive method for determination of 18 polycyclic aromatic hydrocarbons (PAHs) (16 PAHs considered by USEPA as priority pollutants, dibenzo[a,l]pyrene and benzo[j]fluoranthene) in fish samples was validated. Analysis was performed by microwave-assisted extraction and liquid chromatography with photodiode array and fluorescence detection. Response surface methodology was used to find the optima...

Ramalhosa, Maria João; Paíga, Paula; Morais, Simone; Delerue-Matos, Cristina; Oliveira, M. Beatriz P. P.QuEChERS method was evaluated for extraction of 16 PAHs from fish samples. For a selective measurement of the compounds, extracts were analysed by LC with fluorescence detection. The overall analytical procedure was validated by systematic recovery experiments at three levels and by using the standard reference material SRM 2977 (mussel tissue). The targeted contaminants, except naphthalene and acenaphthene, we...
