<i>Scientists identify two new potent greenhouse gases</i>
Scientists have identified two new greenhouse gases - one emitted by the electronic industry and the other used in pest control, which are rapidly accumulating in the atmosphere.
According to a report by ABC News, climate scientist Dr Paul Fraser of CSIRO Marine and Atmospheric Research have reported the measurements of nitrogen trifluoride (NF3) and sulfuryl fluoride (SO2F2), the two new gases.
They say that countries should consider including these gases for control in the revision of the Kyoto Protocol due later this year.
"Although their abundance in the atmosphere is quite low their growth rates are relatively high," said Fraser, who worked with a team at the Scripps Institution of Oceanography in the US.
Fraser said that industry began using the two industrial gases from the late 1990s, partly as alternatives to other harmful greenhouse and ozone-depleting gases.
He said that NF3 was chosen by the electronics industry to replace perfluorocarbons (PFCs), particularly in the manufacture of circuit-boards in liquid-crystal flat-panel screens.
SO2F2 was chosen to replace methyl bromide as a fumigant.
