Some halocarbons such as chlorofluorocarbons (CFCs), previously
The starting point for this theory was their discovery in the south of Russia and South Africa that microbial processes in present-day salt lakes naturally produce and emit highly volatile halocarbons such as chloroform, trichloroethene, and tetrachloroethene.
9 Note: Emissions for this analysis do not include those from agriculture, halocarbons, solvents (nitric and adipic acid) and land use change.
Carbon Dioxide 50% Methane 20% Nitrous Oxide 5% Halocarbons 15% Ozone 10% Note: Table made from pie chart.
Because carbon dioxide and many of the halocarbons have very long atmospheric lifetimes, the increased concentrations are likely to result in an enhanced greenhouse effect in the future.
2]O), and halocarbons (such as chlorofluorocarbons, or CFCs).
Advocates of the precautionary principle cite the introduction of halocarbons and the tear in the ozone hole in the Earth's upper atmosphere, the outbreak of mad cow disease in cattle, growing antibiotic resistant strains of bacteria caused by the over-administering of antibiotics to farm animals and the widespread deaths caused by asbestos, benzene and polychlorinated biphenyls (PCBs).
While there are a number of halocarbon refrigerants available, there is no question that an ammonia central refrigeration system still has the lowest initial installed cost, as well as the lowest operating cost, since it is more efficient than any of the halocarbons and is less expensive to purchase.
Greenhouse gases refer to those whose radiative properties act to insulate the earth by absorbing and re-emitting longwave radiation; significant gases include water vapour, carbon dioxide, methane, nitrous oxide, ozone and halocarbons.
Since the industrial revolution and the expansion of agriculture, however, copious quantities of carbon dioxide and other greenhouse gases -- methane, nitrous oxide, ozone, halocarbons and sulfur hexafluoride -- have been pumped into the atmosphere.
Halocarbons such as CFCs and methyl bromide trigger chemical reactions that break down Earth's stratospheric ozone (SN: 10/14/95, p.
