In this research, the main asked question was; "how does the values of the ratio of the mass of dioxin (an organic compound) to the wet mass of mussels -measured in pgTEQ/gwet- changes when the habitat of Mytilus galloprovincialis mussel (either Black sea, Aegean sea or Marmara sea) changes, by calculating with DR CALUX (abbreviation for Dioxin Responsive Chemical-Activated Luciferase gene eXpression) method under the same gathering time, same season, distance to the lakeshore and depth of the sea where the population of mussels live?". In order to answer that question, this paper used M. galloprovincialis mussels as biotic indicators of dioxin levels that supposedly showed the sea pollution levels of the seas. The mussels, sized 5±1 cm, are gathered from three different locations; Tuzla, "stanbul; Karşıyaka, "zmir and Amasra. Then their dioxin levels are calculated using a method called DR CALUX that used specialized cells to produce light when it attached to a dioxin molecule. After the readings on luminometer, the results arrived. Showing that "stanbul, with mean values of 1.56 pgTEQ per wet mass of mussel, was the highest in the content of dioxin and "zmir followed up with a value of 0.86 pgTEQ/wet mass and at last Amasra was the least that resulted as 0.43 pgTEQ/wet mass that showed significance with p value smaller than 0.001 with ANOVA test. All in all, because of the population differences and the different industrial growth factors affecting the cities they yielded different results in dioxin concentration. Although the results were minimal than other countries, such dioxin level suggests that a serious contaminant was present . As a result, this research concluded by stating the relationship that the mussels are cheap and indirect biotic indicators for detection of especially in determining cancer causing agent dioxin level sea pollutions.
