167:. The potential for methyl iodide to replace the ubiquitous dependence on methyl bromide as a soil fumigant has been considered, however limited information is available on environmental behavior of the former. Ioxynil (3,5-diiodo-4-hydroxybenzonitrile), which inhibits photosynthesis at photosystem II, is among the very few organoiodine herbicides. A member of the hydroxybenzonitrile herbicide class, ioxynil is an iodinated analog of the brominated herbicide, 320: 297: 248: 278: 263: 1736: 1587: 1655: 1492: 174:
Iodinated and brominated organic compounds are of concern as environmental contaminants owing to very limited information available on environment fate behavior. However, recent reports have shown promise in biological detoxification of these classes of contaminants. For example, Iodotyrosine

Almost all organoiodine compounds feature iodide connected to one carbon center. These are usually classified as derivatives of I. Some organoiodine compounds feature iodine in higher oxidation states.
