Sentences with phrase «chlorine concentrations»

See: Fig. 2.3.3 comparing global temperature variation with Effective Stratospheric Chlorine Concentrations.

In fact global equivalent chlorine concentrations have decreased since 1992, and will certainly continue to do so:

In Tulare, Calif., the chlorine concentrations at the recycling plant were extremely high.

The Environmental Protection Agency (EPA), with the help of water utilities, environmentalists and chlorine manufacturers, recently proposed a regulation that would reduce the chlorine concentrations in drinking water to assure that the disinfectant does not approach unsafe levels.

So chlorine concentrations along cell membranes in the gastrointestinal tract are probably too low to cause injury.

Not exact matches

Hydrogen peroxide has the same function as chlorine in hydroponics — that is, it kills undesirable organics, but goes into the atmosphere from a liquid in about 2 hours and leaves no residue in the water; the same can not be said for chlorine, which is residual and may harm plants if the concentration is too high.

However, this concentration of chlorine bleach will not completely disinfect... MORE the diapers by killing all bacteria.

They studied boulders from the New Zealand site where the glacial wood had been found, measuring the concentrations in the rocks of radioactive isotopes beryllium - 10 and chlorine - 36, which are produced by nuclear reactions between minerals and cosmic rays.

At much higher concentrations, chlorine could damage the cells in our body.

These findings led treatment plants to begin manipulating chlorine chemistry in order to lower dichloramine concentrations and, ultimately, reduce NDMA formation.

NASA's upper atmosphere research satellite, for example, carries the British - made microwave limb sounder (MLS) which measures concentrations of chlorine monoxide — a chemical that plays a critical part in the destruction of ozone.

The probe also detected concentrations of chlorine and bromine in the rocks that are consistent with rocks formed by evaporation on Earth and discovered striking «blueberries,» concretions of hematite, a water - related mineral.

Since chloramine does not decrease its concentration nearly as quickly as chlorine when exposed to air, the chloramine should be removed from the water before adding significant amounts of tap water to your pond.

While the concentration of chlorine in swimming pools isn't dangerous for dogs under normal circumstances, it can still cause health issues.

The Montreal Protocol and its subsequent amendments have decreased the concentrations of many CFCs and chlorinated solvents where total equivalent chlorine peaked in 1993 - 94 and has decreased by 8 % by the end of 2005 (Figure 2).

6 Ice age — time in the past when continental glaciers covered large parts of Earth's surface Global warming — a gradual increase in the temperature of Earth's atmosphere Greenhouse gas — Gases in the atmosphere, such as carbon dioxide, that trap solar energy Ozone hole — a large area of reduced ozone concentration in the stratosphere, found over Antarctica Chlorofluorocarbon — chlorine compounds that are the main cause of ozone depletion KEY TERMS

The Montreal Protocol may have prevented the atmospheric concentrations of chlorine from getting worse by getting rid of CFCs in developed countries (but the black market will ensure they are readily available in developing countries for years to come unless more is done soon), and because the CFCs are enormously powerful greenhouse gases (5000 - 11,000 time more powerful than CO2, in round figures) Montreal has done 5 times more to abate emissions than Kyoto will in the first commitment period.

Chlorine is easy to smell at concentrations much less than fatal.
