Dioxide in a sentence

An earlier study compared the effect of carbon dioxide emissions on immature shellfish in waters with carbon dioxide at preindustrial levels versus water with carbon dioxide at levels with concentrations expected by 2100.

The crystals have the empirical formula of silicon dioxide, but do not consist of discrete silicon dioxide molecules in the manner of solid carbon dioxide.

Carbon neutrality is a state of net-zero carbon dioxide emissions that can be achieved by ending the use of coal, oil and gas or by participating in efforts to offset those emissions through other carbon dioxide reduction platforms.

The assessment is expected to help quantify sulphur dioxide, nitrogen dioxide, and particulate matter emissions in the Manali industrial cluster and suggest an effective mitigation plan.

These included PM2.5 — which stands for particulate matter less than 2.5 micrometers in diameter — nitrogen dioxide (NO2), nitric oxide (NOx) and sulfur dioxide (SO2).

Aside from the carbon dioxide released from airplanes, Alvarez said, the Dallas-Fort Worth airport became the first United States airport to achieve carbon neutrality in 2016, meaning that it releases no carbon dioxide into the atmosphere.

Because soybeans actually absorb and utilize carbon dioxide while growing, this offsets any carbon dioxide released during soy biodiesel combustion.

However, the conventional method of combustion - burning carbon dioxide - ends up producing more carbon dioxide, Dr Jain said.

In 2011, leaked memos showed that the institute paid contrarian scientists like Craig Idso, founder of the Center for the Study of Carbon Dioxide and Global Change, to promote carbon dioxide as beneficial to the environment.

The increase in turnover rates of carbon dioxide has raised levels, but it is not simply carbon dioxide, industrialisation has released other molecular compounds as well.

The simulation also illustrates differences in carbon dioxide levels in the Northern and Southern Hemispheres and distinct swings in global carbon dioxide concentrations as the growth cycle of plants and trees changes with the seasons.

Trees absorb a wide range of airborne pollutants, including carbon monoxide, sulfur dioxide and nitrogen dioxide.

According to the National Center for Policy Analysis, man-made carbon dioxide amounts to under 4 percent of all carbon dioxide.

Every human breath contains about 40,000 parts per million (ppm) carbon dioxide, 100 times higher than current atmospheric carbon dioxide levels.

The air quality research group placed monitoring units around the UK to track levels of nitrogen dioxide, ozone, particulate matter, sulphur dioxide and carbon monoxide.

Although carbon dioxide levels have changed naturally over the past several thousand years, human emissions of carbon dioxide into the atmosphere exceed natural fluctuations.

A sharp increase in atmospheric carbon dioxide was observed with a maximum of 4000 ppm: the highest amount of atmospheric carbon dioxide detected during the Eocene.

Carbon dioxide levels and photorespiration Photorespiration As carbon dioxide concentrations rise, the rate at which sugars are made by the light-independent reactions increases until limited by other factors.

Carbon dioxide was known to be taken in and oxygen released during photosynthesis, but researchers suggested that oxygen was obtained from carbon dioxide, rather than from water.

Carbon market main Carbon emissions trading is emissions trading specifically for carbon dioxide (calculated in tonnes of carbon dioxide equivalent or tCO 2 e) and currently makes up the bulk of emissions trading.
