Note

Hydrogen sulfite, also known as bisulfite or hso3(-), is a member of the class of compounds known as non-metal sulfites. Non-metal sulfites are inorganic non-metallic compoundscontaining a sulfite as its largest oxoanion. Hydrogen sulfite can be found in a number of food items such as narrowleaf cattail, canola, winter savory, and black salsify, which makes hydrogen sulfite a potential biomarker for the consumption of these food products.
