This is one of the fields contained within the Environmental Fate superfield (ZENE). For more general information regarding Environmental Fate, see the Environmental Fate message field (ENEX).

The search above will retrieve those records for which there is information on the photochemistry of the substance.

Information on chemical decomposition processes is contained in the ABIO field. The energy from the sun is able to break carbon-carbon and carbon-hydrogen bonds, cause photodissociation of nitrogen dioxide to nitric oxide and atomic oxygen and photolytically produce significant amounts of hydroxyl radicals. Hydrolysis occurs when a substance present in water is able to react with the hydrogen or hydroxyl ions of the water. Therefore the extent of photolytic and oxidative reactions occurring in the atmosphere and hydrolysis in water can be used as a measure of environmental pollution likely to arise from exposure to a substance.
