| Summary: | The Marmara Sea is a semi closed fishing area in Turkey and has valuable fish species such as the
common sole, black scorpionfish and horse mackerel. Domestic waste, generated by the population
of over 25 million living in the coastal zone as well as industrial facilities in the region are the
main causes of pollution in the Marmara Sea. In the current study, the levels of toxic metals (arsenic,
cadmium, mercury, and lead) in samples of three fish tissue were analysed over a year-long
period and compared with international results. The health risks for different age groups caused
by the consumption of these fish were estimated. The results revealed that regular weekly consumption
of sole and horse mackerel caught from the Marmara Sea posed health risks for child
and youth populations. These fish species should be consumed more carefully due to potential
arsenic-related hazards and carcinogenic risks for vulnerable consumer groups.
