摘要

Four species of red and green Antarctic macroalgae were exposed to various photon fluxes for periods of 6.45 and 17.45h, respectively, and the release of 12 volatile halogenated compounds from chloromethane to diiodomethane was monitored. The results showed that variation of light conditions has an influence on the formation and release of volatile halocarbons, but no clear light-dependent relationships were found. In general, higher release rates were exhibited at no light or low photon fluxes.
