Properties of VOCs. As with many poisonous plants there are many reasons for their use, both good (medicinal) and bad (weapons and poisons). A common finding is that unregulated nitrogenous DBPs tend to drive cytotoxicity more potently than the regulated carbonaceous DBPs [14, [17], [18], [19]]. Inorganic arsenic compounds (such as those found in water) are highly toxic while organic arsenic compounds (such as those found in seafood) are less harmful to health. The toxic potential of the 17 congeners can be expressed relative to the most toxic compound by the concept of toxic equivalence (TEF, toxic equivalent factor).
