Does shellfish contain arsenic?

Seafood, including finfish, shellfish, and seaweed, is the largest contributor to arsenic (As) exposure in many human populations. In contrast to the predominance of inorganic As in water and many terrestrial foods, As in marine-derived foods is present primarily in the form of organic compounds.

Is there arsenic in rice?

Dietary Sources of Arsenic Arsenic is found in nearly all foods and drinks, but is usually only found in small amounts. Rice and rice-based foods: Rice accumulates more arsenic than other food crops. In fact, it is the single biggest food source of inorganic arsenic, which is the more toxic form ( 7 , 8 , 9 , 10 ).
