Determination of PAHs, PCBs, minerals, trace elements, and fatty acids in Rapana thomasiana as an Indication of pollution

The aim of this investigation was to introduce several analytical methods for determination of polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), minerals, trace elements, and fatty acids in Rapana thomasiana as a marine pollution indicator organism. The chemical differences of the gastropod Ra. thomasiana from polluted and nonpolluted sites of the Black Sea on the Bulgarian coast were investigated. Chromatography and high-resolution inductively coupled plasma/MS analyses were used for evaluation of PAHs, PCBs, fatty acids, minerals, and trace elements. These methods can be applied to other marine products.
