The current year, 2005, will see Parties undertake commitments to further controls on CFCs, halons, carbon tetrachloride, methyl chloroform and methyl bromide.

Other representatives stressed the need to consider additional reduction steps for methyl bromide, as well as the variable reporting of carbon tetrachloride data.

In previous years, Switzerland has reported consumption of carbon tetrachloride and methyl chloroform for laboratory and analytical uses consistent with the Protocol's global laboratory and analytical use exemption.

To monitor closely the progress of Switzerland with regard to the phase out of Annex B, group II, substances (carbon tetrachloride) and Annex B, group III, substances (methyl chloroform).

Switzerland reported consumption of 4.730 ODP tonnes of carbon tetrachloride and 348.300 ODP tonnes of methyl chloroform in 2004 for essential uses.

E. Decision XVII Potential non compliance in 2004 with consumption of the controlled substance in Annex B, group II (carbon tetrachloride), and Annex B, group III (methyl chloroform), by Switzerland, and request for a plan of action

The Committee observed that, at its first meeting, it had considered notifications concerning regulatory actions on methyl bromide and on carbon tetrachloride, some of which were based on decisions or assessments under the Montreal Protocol on Substances that Deplete the Ozone Layer.

There is also an interaction between MSG and salt (sodium chloride) and other umami substances, such as nucleotides.

Structure In its gas phase, RbCl is diatomic with a bond length estimated at 2.7868 Å.

She explained that MBTOC had undertaken an extensive revision to the methyl bromide handbook, which was available for review.

The Committee also recommended that table B of decision XV 7 be updated to reflect any changes made to table A and that Israel be included in table B because its use of carbon tetrachloride (CTC) for removing nitrogen trichloride (NCL3) in the production of chlorine was a well known process agent use.

As for carbon tetrachloride emissions and reduction opportunities, he noted that while there had been data uncertainties, 2002 production of CTC was less than 200,000 metric tonnes, with almost half coming from developing countries.

Due to the radioactivity of plutonium, all of its compounds, PuCl3 included, are warm to the touch.

Magnesium chloride is the name for the chemical compounds with the formulas MgCl2 and its various hydrates MgCl2(H2O)x.
