According to the World Health Organization, seafood is a common source of dietary arsenic, yet the vast majority is in a non-toxic form. The presence of arsenic in seafood is primarily due to natural processes within the marine food chain, where it is absorbed by marine organisms from seawater and converted into a less harmful substance.

According to the World Health Organization, seafood is a major source of dietary arsenic, yet the form of arsenic is the key determinant of its toxicity. This means that when asking, 'Do sardines have more arsenic than salmon?', the answer is more complex than a simple yes or no and requires understanding the different types of arsenic found in fish.

Fish is the largest dietary source of arsenic for most people, yet the chemical form of arsenic is the most critical factor for human health. So, when asking 'Is arsenic in salmon?', the answer is more nuanced than a simple yes or no, centering on the distinction between toxic inorganic arsenic and its benign organic counterpart.

While it's true that seafood is the largest dietary source of arsenic for many people, the vast majority of this element in fish exists in a much less toxic organic form. This fact is critical for understanding the actual health implications of whether and why fish have arsenic in them.
