| Abstract: | The purpose of this study was to evaluate the contamination caused by polychlorinated naphthalenes in two polluted Mediterranean lagoons. Surface sediment samples from Venice and Orbetello lagoons were analysed using HRGC-HRMS. The levels of the sum of mono- to octa-CN ranged from 0.03 to 1.51 ng/g. Differences in PCN levels were observed as a function of the sampling site, with levels at the industrial sites exceeding those at the control sites. Although the PCN patterns and profiles resembled one another in different sediment samples, they differed considerably when compared with those in the technical PCN formulation Halowax 1014. |
