ABSTRACT
The broad family of halocarbons includes chemical compounds that, in addition to carbon and hydrogen, contain fluorine, bromine, chlo-rine, or iodine. This group of compounds includes substances of both biogenic and anthropogenic origin that are ubiquitous trace constituents of the oceans and of the atmosphere. They are involved in a number of atmospheric reactions, among which the destruction of stratospheric ozone is the most remarkable.
