Halogenated pollutants, aquatic

These discussions indicate that aquatic photochemical processes play an im portant role as sinks for halogenated pollutants and as a source of certai natural halocarbons, including volatile halocarbons that escape from the se to the atmosphere. Those photoreactions that provide sinks often result i dehalogenation. Direct photoreactions such as photohydrolysis are likely to b the dominant photoreactions of aromatic halocarbons that strongly absorb sc lar radiation.
