Brief Summary

Alkylated naphthalenes are major constituents of water soluble fractions of crude oils, dominate oil industry produced waters and are common contaminants within tissues of marine biota, such as the mussel, Mytilus spp. It is important that environmental monitoring studies do not ignore these toxic compounds. However, most studies only rarely report alkyl naphthalenes with alkyl substituents >C3, possibly due to the complexity involved with the separation of the thousands of isomers which are theoretically possible. In this study we use GCxGC-TOF-MS to compare alkylnaphthalenes accumulated in lab-exposed and wild mussels.
