- Abiotic degradation of hydroxylamine by photochemically produced peroxy radicals is an important environmental fate process in surface waters, with the half-life of this reaction measured at ∼2 h. An estimated bioconcentration factor of 3 suggests the potential for bioconcentration in aquatic organisms is low. View chapter Purchase book
