Abstract
The consumption of marine fish as popular seafood has increased steadily over the past decades. Toxic effects evidenced in the environment are most often caused by a mixture of pollutants such as heavy metals. The daily intake of arsenic (As) and mercury (Hg) through the consumption of nine edible marine species by the general population of Bulgaria was estimated. Health risks derived from this intake were also assessed. The concentrations of As and Hg in nine edible marine fish species were determined by ETAAS and Milestone Direct Mercury Analyzer. The highest metal intake through fish consumption corresponds to As (7.837 μg/day) for male adults. The daily intake of these elements through fish consumption of these elements was compared with the provisional tolerable weekly intakes (PTWI). The data of this study showed that the metal concentrations in edible tissues of the sampled species were within the permissible safety levels for human consumption set by various health organizations.
