Waste water biochemical oxygen demand (kg)

We have to detect oxygen or ozone to make sure that we have all necessary conditions to have life.

The oxygen is bound by metabolism, we use it for energy.

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

A hypoxic tent is a tent that simulates altitude at 15,000 feet.

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

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

Everybody's on oxygen, your supplies are limited, and you either have to go up or go down, make that decision very quickly.

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.

Box 1. CO2 and N2O emissions from the transport sector

This is mainly caused by a steep decrease in the emissions of CFCs, primarily from refrigeration plants (from 1.6 Gt CO2 eq to 0.3 Gt CO2 eq), responding to the requirements of the Montreal Protocol.

For 13 Parties, CO2 emissions from fuel combustion represented more than 90 per cent of the total CO2 emissions.

(i) Reduce emissions of nitrous oxide.

And we then thought to ourselves, with those big stores, I wonder if sunlight might activate those stores and release them from the skin, where the stores are about 10 times as big as what's in the circulation.

And because you can't bind the oxygen, maybe you wouldn't consume it, and then maybe it would reduce your demand for oxygen.

We're actually measuring its oxygen consumption, its energy consumption.

Future ozone concentrations are mainly driven by the changes in stratospheric halogen loading, with ozone recovery occurring after the peak of halogen loading.

The use of wood products in place of materials that are associated with the release of large volumes of carbon dioxide could lead to significant net reductions in carbon dioxide emissions.

The largest share of total GHG emissions expressed in CO2 equivalent was that of carbon dioxide, accounting for 83 per cent.

The demand for parking, of course, is down, congestion and the CO2 emissions.

Carbon dioxide level has gone up and up and up.

We inject our own aerosols into the atmosphere, and we have trace gases, and not just carbon dioxide it's methane, ozone, oxides of sulfur and nitrogen.

We need to reduce C02 emissions in ten to fifteen years by 80 percent in order to avert catastrophic effects.

Nitrous oxide will remain a small component of Icelandic emissions.

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.

The ability to predict future ozone behavior requires quantification of the roles of chemical and dynamical processes responsible for ozone production, loss, and distribution, and their uncertainties.

It is the spectrum of a planet like Earth, showing a presence of nitrogen dioxide, as a clear signal of life, and oxygen and ozone.

Ozone is a greenhouse gas, and quantifying its role in climate change requires continued high quality measurements of both total abundance and vertical profile.

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

Moreover, the electricity required to charge an electric car is overwhelmingly produced with fossil fuels. Yes, it then emits about half the CO2 of a conventional car for every kilometer driven (using European electricity).

I came here to speak about ecology, and I emitted as much CO2 as a Frenchman in one year.

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.

Many noted that measures to mitigate CO2 or CH4 emissions in energy and agriculture would also reduce N2O emissions.

(b) Reduction of CO2 emissions from newly registered cars

The projections of CO2 emissions from bunkers are presented separately.

The project is a mechanical processing enterprise. Its initial emission rate for the chemical oxygen demand (COD) and ammonia (NOX) are 0.514 tons year and 0.052 tons year, respectively.

Total CO2 emissions amounted to 2,387,000 Gg in 1990, which represented 11 per cent of the global CO2 emissions, making the Russian Federation the world apos s second highest emitter of energy related CO2.

Trends in CO2 emissions from transport, total CO2 emissions and total GHG emissions

So, what we're going to do is that we're going to measure a few basic parameters on you, including your pulse rate and the amount of oxygen that's there in your blood.

Hungary is committed to stabilizing national emissions of CO2, and the communication also made a reference in the preface to the commitment to stabilize greenhouse gas emissions.

Use of oil with tetra ethyl lead causes much pollution, with lead containing carbon monoxide, nitrogen oxide and policyclic nitro hydride.

A number of ozone vertical measurements have been proposed.

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.
