FOR KIDS: Indoor ozone stopper1

It may seem like good news that human skin helps indoor spaces fight off dangerous ozone. After all, if the ozone goes away, then a person won’t breathe it and face the bad health effects.

But that may not be the case: Emerging research suggests this battle with ozone might present its own dangers. Office 2007 key is very convenient!

In a different experiment, scientists in Austria mixed together ozone and skin oils in the laboratory. They found that, even though this mixing gets rid of ozone, it also creates new kinds of pollution. One in particular, called 4-oxopentanal (or 4-OPA), might be particularly dangerous. Until now, scientists have not analyzed 4-OPA to see how toxic it is, but that’s changing.

Yet another team of scientists are working on this chemical at the National Institute for Occupational Safety and Health in Morgantown, W.V. In early studies, the researchers found evidence that 4-OPA may be even worse than ozone. In other words, the ozone may be gone — but what’s left in its place may be even worse for human health.Office 2010 download is available now!

In the end, scientists want to know exactly what’s going on with the molecules that we breathe — and they hope this information will help us find new ways to protect our health. But the scientific journey from the first experiment (in the children’s bedrooms) is long, requiring study after study by scientists who can learn from each other.

POWER WORDS

ozone A poisonous form of oxygen that forms naturally in the atmosphere when oxygen is exposed to ultraviolet radiation. It is also produced in the lower atmosphere by the chemical reaction of certain pollutants.

phthalates Various forms of phthalic acid. Used in plastics and solvents.

chemistry The science of the composition, structure, properties and reactions of matter, particularly of atomic and molecular systems.

oxygen A nonmetallic element constituting 21 percent of the atmosphere by volume and is in many compounds such as water and iron ore. It combines with most elements, is essential for plant and animal respiration, and is required for nearly all combustion.Buy Office 2007 you can get much convenience.

Genome-wide association studies, which comb through these giant databases looking for links between genetic and physical traits, have the potential to generate clinically valuable information. Establishing such links could help doctors understand, for example, why patients respond differently to certain drugs.
