For Sri Lanka, the greater concern is on account of the entry into the lungs of human beings of toxic gases and particulate matter, including carbon monoxide, hydrocarbons, nitrous oxide, sulphur dioxide and airborne carbon and lead.

The phenomena studied are also unchanging in their nature, causes and vectors.

They indicate that CO2 emissions are projected to decrease by 33 per cent, CO by 40 per cent, NOx by 8 per cent and NMVOC by 27 per cent.

Excess carbon dioxide is not only driving global warming, it's also changing ocean chemistry, making the sea more acidic.

352. Annex VI prohibits deliberate emissions of ozone depleting substances, which include halons and chlorofluorocarbons (CFCs), and sets limits on the emissions of sulphur oxide and nitrogen oxide from ship exhausts.

And when media evolve so that the identity of the media becomes increasingly unique.

Parties should also provide information on the indirect greenhouse gases carbon monoxide (CO), nitrogen oxides (NOx) and non methane volatile organic compounds (NMVOCs), and are encouraged to provide data on sulphur oxides.

Climate change associated with increased abundances of greenhouse gases is expected to alter the nature and timing of ozone recovery.

(c) The substance is in compliance with 2.4.2.3.2.5(b) or 2.5.3.2.5.1 if it is a self reactive substance or an organic peroxide, respectively

But carbon dioxide is carbon dioxide.

are authorized for the transport of any liquid or solid substance other than explosives, thermally unstable substances, organic peroxides, self reactive substances, substances where significant pressure may develop by evolution of chemical reaction and radioactive material (unless permitted in 4.1.9).

Magnetic thin films 73. Over the last decade, magnetic thin films have replaced metal oxide particles as the source of magnetic flux in rigid disk magnetic storage media.

(a) The availability and cost of chemical substitutes and of alternative technologies to reduce the emissions of ozonemodifying substances and related planned and ongoing research

Emissions of nitrous oxide (N2O) totalled 108 Gg, carbon monoxide (CO) 6.7 Gg, nitrous oxide (NOx) 2,740 Gg and non methane volatile organic compounds (NMVOC) 25,400 Gg.

If necessary the concentration of the organic peroxide or self reactive substances can be lowered.

4.2.1.13.3 Insert quot or self reactive substances quot after quot organic peroxides quot .

4.2.1.13.15 Insert quot and self reactive substances quot after quot organic peroxides quot .

The criteria defined and used by the panel are as follows (i) biological agents and toxins known to have been effectively weaponized by Iraq but also reported in open sources to have been weaponized in other biological warfare programmes elsewhere (ii) biological agents and toxins known to have been subject to attempts to weaponize and (iii) biological agents and toxins relatively easy to weaponize because of their properties.

Unable to determine the current formatting state of the DVD RW medium.

Carbon dioxide, a little bit of sunlight, you end up with a lipid that is highly refined.

Other ODS are also being considered for inclusion.

No Media inserted or Media not recognized.

The national communication includes aggregated emission estimates using global warming potentials (GWP), with CO2 emissions contributing 80 per cent of total emissions expressed as CO2 equivalent, methane (CH4) 12 per cent, nitrous oxide (N2O) 7 per cent and indirect GHG nitrogen oxides (NOx), carbon monoxide (CO), and non methane volatile organic compounds (NMVOC) 1 per cent.

2.1.4.1 In the last but one sentence, replace in Division 5.1 with as an oxidizing liquid (Chapter 2.13) or an oxidizing solid (Chapter 2.14) and in the last sentence replace 2.1.3 with 2.1.4

Pressure relief devices shall operate at pressures determined according to both the properties of the organic peroxide and the construction characteristics of the portable tank.

But I also became interested in research, and in particular I became interested in this substance, nitric oxide.

In the national communication or as additional information obtained during the in depth review, inventory data were provided on the main GHGs carbon dioxide, methane (CH4) and nitrous oxide (N2O), and the precursors nitrogen oxides (NOx), carbon monoxide (CO) and non methane volatile organic compounds (NMVOCs), for the years 1989, 1990 and 1991.

40.1.1 Part IV of the Test manual presents the United Nations schemes for dynamic and longitudinal impact testing of portable tanks and MEGCs (see section 41 of this Manual and 6.7.2.19.1, 6.7.3.15.1, 6.7.4.14.1 and 6.7.5.12.1 of the Model Regulations).
