Contribution of commercial fish species to human mercury exposure: An evaluation near the Mid-Atlantic Ridge

•Only 2 of the 28 fish species analysed exceeded the Hg limits for fish consumption.•The 28 fish species contribute every year to about 1.8 kg of Hg for human exposure.•Amount of fish landing plays a more determinant role than [Hg] in human Hg exposure.•An exposure at this level (THQ < 1) is not likely to cause any negative health effects.
