This study analyzed trace elements in various shellfish, finding levels below Danish action limits. Shellfish consumption is not a significant source of cadmium, lead, or mercury intake.

Area of Science:

  • Environmental Science
  • Food Safety
  • Analytical Chemistry

Background:

  • Trace elements are crucial for human health but can be toxic at high concentrations.
  • Shellfish are known to accumulate heavy metals from their environment.
  • Monitoring trace element levels in seafood is essential for public health protection.

Purpose of the Study:

  • To quantify cadmium, lead, mercury, nickel, chromium, arsenic, and selenium in various Danish shellfish species.
  • To assess the contribution of shellfish consumption to the dietary intake of these trace elements.
  • To compare measured concentrations against established Danish action levels.

Main Methods:

  • Atomic absorption spectrometry and inductively coupled plasma mass spectrometry were used for trace element analysis.

  • A range of shellfish, including shrimps, mussels, lobster, langoustine, crayfish, crab claws, and oysters, were analyzed.
  • Dietary intake estimations were performed based on typical consumption patterns.

    • Main Results:

    • All analyzed shellfish samples were below the Danish action levels for cadmium and mercury.
    • The highest lead concentration in shellfish was close to, but did not exceed, the Danish action level.
    • Shellfish consumption was found to be a minor contributor to the overall dietary intake of the investigated trace elements.

    Conclusions:

    • Danish shellfish generally contain safe levels of the analyzed trace elements.
    • The risk associated with consuming these shellfish regarding cadmium, lead, and mercury is low.
    • Further monitoring may be warranted for lead, given its proximity to action levels in some samples.
