Investigation and research into microplastics has drastically increased in popularity in recent years due to the high abundance that has been found as marine litter in the environment, however microrubber has not received the same level of attention. Therefore there is far less knowledge on the subject of rubber than plastic in marine ecosystems, in general. Several reports show an increasing amount of tyre run off from the main-land ending up in aquatic environments, which has the potential to cause serious bio hazard problems. This study investigates whether the polycyclic aromatic hydrocarbons, (PAHs) which are found in rubber, are accumulated in the tissue of Mysida spp. PAHs are organic chemicals known for their carcinogenic and mutagenic properties and have been shown to be transferred from microplastic to the tissue of marine animals during ingestion. No study has shown the same effect happening with microrubber as we set out to test. A chronic experiment is conducted where the test animals were exposed to 4 different dietary concentrations of microrubber. The tissue samples were analysed using a GC/MS. The results came out with no indication of PAH bioaccumulation. However, we discuss the possible reasons for this to be an analytical issue. We were therefore not able to conclude any correlation between dietary exposure to microrubber and an increase in PAHs in the tissue of Mysida spp..
