This element is known to bioaccumulate in humans, so bioaccumulation in seafood carries over into human populations, where it can result in mercury poisoning. [31], Certain countries have cultural differences that lead to more fish consumption and therefore more possible exposure to seafood methylmercury. 4. [23][failed verification] Addressing the issues of fish consumption forces health officials to recognize the sources of mercury in the human body. Mercury levels in fish vary between species depending on habits and feeding patterns. Scales are slightly ctenoid. All fish are also a significant source of vitamin D and .
