Abstract The drastic increase of human population and industrial wastes mostly affects coastal areas. Crabs with limited mobility, especially in benthic regions of the coasts, are more affected by metal pollution. Monitoring of trace metals in terms of food safety and potential health risks is important for consumers. Warty crab (Eriphia verrucosa) samples were collected with trammel nets between July 2015 and June 2016. The crab extracts were analyzed by an ICP-MS optical emission spectrophotometer. Trace metal densities of crab meats in the present study were determined in the order of Zn > Cu > Fe > As > Al > Mn > Hg > Pb ≥ Cd. These levels were below the acceptable values reported by the Turkish Food Codex and the EU Commission. The target hazard quotient (THQ) was above 1 in terms of As, Cu, and Hg trace metals in both groups. This study showed that although the level of trace metal was below allowable values, consumption of warty crab more than once a month may cause metal toxicity according to potential health risk analyses.

Introduction The interest in the consumption of fish, mollusks, and crustaceans is increasing all over the world with the understanding of its benefits to human health in the prevention of diseases such as cardiovascular and obesity (Marengo et al. 2018). Seafood is an excellent mineral source, especially in terms of calcium, potassium, zinc, phosphorus, and iron (Duyar and Bilgin 2019; Gökoğlu and Yerlikaya 2003). However, the concentrations of trace metals naturally found in aquatic ecosystem increase as a result of the growing population, developing industries, transportation, agriculture, urbanization, and other human activities (Marengo et al. 2018; Jerome and Chukwuka 2016). Trace metals are toxic and biodegradable environmental contaminants that can cause serious damage to the circulatory system, central nervous system, excretory system, and reproductive systems when they accumulate in the

tissues of organisms and reach high levels (Stankovic et al. 2014). Trace elements such as copper (Cu), manganese (Mn), zinc (Zn), and iron (Fe) are essential for the metabolic activities of living beings; however, high amounts of these elements can have toxic effects (Makedonski et al. 2017; Mol et al. 2010). Metals such as arsenic (As), lead (Pb), cadmium (Cd), and mercury (Hg), which can be within the body of aquatic organisms, are completely toxic (Mol et al. 2018). Since increasing population and industrial wastes mostly affect coa
