There's diatoms made out of SIO2, and they're magnetotactic bacteria that make small, single domain magnets used for navigation.

Carbon dioxide level has gone up and up and up.

But carbon dioxide is carbon dioxide.

Ethylene oxide and carbon dioxide mixture with more than 9 but not more than 87 ethylene oxide

However, UN 1975 Nitric oxide and dinitrogen tetroxide mixture may be transported in pressure drums.

1 GT (or gigatonne) CO2 equivalent means 1,000 million of tonnes of CO2.

MT (or mega tonne) of CO2 equivalent means 1,000,000 tonnes of CO2.

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.

Ireland apos s own CO2 abatement strategy aims at limiting the growth in CO2 emissions to 20 per cent over 1990 levels by the year 2000.

emissions to air TRI toxics, sulphur dioxides, nitrogen oxides, CO2 etc.

Instead of cement usually emits a ton of CO2 for every ton of cement.

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.

Trees give off oxygen and absorb carbon dioxide.

We can't see CO2 we depend on scientific measurements for it and we see the beginning results of having too much of it but we can see pre CO2 now floating on the waters and contaminating the beaches in the Gulf.

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.

The majority of them target CO2 emissions with consequent effects on N2O and ozone precursors.

The large scale existence of these photosynthetic bacteria (capable of using light to synthesize carbohydrates from carbon dioxide and water) and algae also has implications for global warming, among other things.

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.

Oxalic acid is two carbon dioxide molecules joined together.

3 The anthropogenically produced greenhouse gases include carbon dioxide (CO2) methane (CH4) nitrous oxide (N2O) hydrofluorocarbons (HFCs) perfluorocarbons (PFCs) and sulphur hexafluoride (SF6).

1 The World Health Organization recognizes six main types of air pollutants carbon monoxide, nitrogen dioxide, particulate matter, sulphur dioxide, tropospheric ozone and suspended particulate matter.

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.

N2O emissions from agricultural sector represented roughly 87 per cent of the total N2O emissions.

It broke down it took oxygen out of the air it put CO2 into the air and it went into the concrete.

They're nothing but H2O with a trace of sodium chloride.

In terms of trends regarding key gases, data from several sources had suggested that CFC levels were stable or decreasing and currently amounted to 1.5 1.9 GT of carbon dioxide equivalents, HCFC levels were increasing by 1 3 per cent per year and currently amounted to 0.53 0.56 GT of CO2 equivalents, and HFC levels were increasing by 13 17 per cent per year and currently amounted to 0.36 GT of CO2 equivalents.

Total emissions of HFCs, PFCs and SF6 (gigagrams of CO2 equivalent)

Cars and trucks add up to about 25 percent of the world's CO2 emissions.

CO2 represented 82 per cent of 1990 emissions, methane (CH4) about 8 per cent and nitrous oxide (N2O) about 10 per cent.

Omissions identified by the review team include CO2 emissions from land use change, CO2 from incineration of carbon in waste, N2O from the manufacture of inorganic chemicals and N2O from animal wastes.

The fastest growing source of CO2 emissions for the majority of Parties was transport, where emissions were increasing even for some of those Parties which in 1995 registered lower levels of total CO2 emissions than in 1990.

They've borrowed the recipe from the coral reef, and they're using CO2 as a building block in cement, in concrete.

Now, as we breathe, we produce carbon dioxide, and that carbon dioxide needs to be scrubbed out of the system.

From SiO maser sources towards the galactic centre, the average rotation period of the galactic bulge was found to be 8.5 x 107 years.

The original target of the United Kingdom s GHG programme set in 1994 was to return CO2emissions in 2000 to their 1990 level by achieving a reduction of around 37,000 Gg CO2 or 10 million tonnes (Mt) of carbon (C).
