“…Their role in the global circulation of halogens and in atmospheric chemical reactions has been discussed extensively within the last few years in connection with their ability to affect the atmospheric ozone budget. Marine macroalgae have been shown to produce a wide variety of volatile halocarbons, mainly brominated ones [Burresort and Moore, 1975;Moore, 1977;Fenical, 1981;Gschwend et al, 1985;Manley and Dastoor, 1987;Newman et al, 1987;Class and Ballschmiter, 1988].…”

Hitherto unnoticed biogenic volatile iodated hydrocarbons have been determined in open ocean and coastal surface waters. The results indicate that iodated substances are produced by planktonic organisms rather than by macroalgae. It is shown that the diversity of iodated organic compounds released in the seawater is larger than was previously suggested. In the global cycling of iodine it is necessary to consider organic compounds other than methyl iodide.

“…Of the volatile halogenated compounds, halomethanes are the group that has been most widely investigated, with the major sources thought to be macroalgae (Moore 1977;Gschwend et al 1985;Newman et al 1987). Production rates of brominated halomethanes and methyl iodide for macroalgae have been reported to be in the range of hundreds of ng g-l fresh wt (FW) d-l to hundreds of pg g-l FW d-l for the Atlantic (Gschwend et al 1985) and the Pacific (Manley and Dastoor 1987;Manley et al 1992).…”

Marine algae -a source of trichloroethylene and perchloroethylene Abstract-Our results show the natural production of two olefins, trichloroethylene and perchloroethylene, by various marine macroalgae and a microalga. We found significant difference in the ability of the algae to produce these compounds. The production rates for trichloroethylene varied between 0.022 and 3,400 ng g-l fresh wt (FW) h-l and were generally higher than those for perchloroethylene (0.0026-8.2 ng g-l FW h-l). The two subtropical algae, Asparagopsis taxiformis and Falkenbergia hillebrandii, showed the highest formation rates. One axenic marine red microalga, Porphyridium purpureum, was also tested and it could also produce trichloroethylene and perchloroethylene. The measured rates suggest that the emission of trichloroethylene and perchloroethylene from the oceans to the atmosphere may be of such a magnitude that it cannot be neglected in the global atmospheric chlorine budget.

“…In addition, GC-SM allowed the detection in the sediment of halogenated hydrocarbons (bromoalkanes and chloroalkanes). These products have been shown to occur naturally in various marine environments (Moore 1976;Helz and Hsu 1978;Gschwend et al 1985;Newman and Gschwend 1987).…”

International audienceWe investigated the coupling of abundance of bacteria, phytoplankton and ciliates with hydrocarbons in the surface water and sediments of five interconnected ponds in the arid Sfax solar salterns. This study aimed at determining the potential sources of hydrocarbons and the effects of salinity gradients on microorganism metabolism. Hydrocarbon analysis was performed by gas chromatography (GC-FID) and gas chromatography coupled with mass spectrometry (GC-MS). The GC-FID allowed the detection of aliphatic hydrocarbons and n-alkanes ranging from n-C13 to n-C30. Total aliphatic hydrocarbon concentrations varied from 92.5 mg. l−1 in the first pond (having marine characteristics) to 661.1 mg. l−1 in the last pond (crystallizer) (316.8±120.1 mg. l−1) for water samples and from 26.7 to 127.8 !g. g−1 dry weight for sediment samples. The GC-MS enabled us to detect halogenated hydrocarbons (bromoalkanes and chloroalkanes) and n-alkenes. The distribution of n-alkanes indices coupled to several environmental factors suggests that a major fraction of hydrocarbons resulted from both prokaryotic (bacteria) and eukaryotic (protists) developments. A low hydrocarbon fraction might be petrogenic
