According to a new research paper released by the European Space Agency (ESA), the ozone depletion in our atmosphere is leveling off, a direct consequence of the banning of chlorofluorocarbons (CFC) with the Montreal Protocol, signed in 1987. A fine example of how nations can come to work together when faced with a c... |

The 193 nations that signed together the 1989 Montreal Protocol showed, at the time, the level of cooperation that could be achieved at an international level, if the faith of the planet was at stake. Thanks to these nations, chemicals such as chlorofluorocarbons (CFC) and other dangerous substances were entirely pha... |

Over the 20th century, mankind has emitted a number of dangerous chemicals into the atmosphere, of which the most damaging to the planet have been chlorofluorocarbons (CFC). These substances have had a direct and adverse effect on the ozone layer, making it thinner over the years, and finally breaching it over Antarc... |

When one thinks about the problems the world is facing today, one thinks of financial crisis, tense international relationships or pollution, but there are, actually, many people who would wish to have to worry only on these accounts. Changing all these wouldn't affect the fact that about 1 of 8 persons in the w... |

This is the first time when hydroxyl molecules are detected outside Earth and the finding could unravel some of the secrets to how Venus' dense atmosphere works. Hydroxyl, if you still remember a little bit of chemistry from school, is a compound consisting of one atom of hydrogen and one of oxygen. This substan... |

Up into the stratosphere, the ozone layer protects life on Earth by reflecting harmful UV light. But in the troposphere (lower atmosphere), another ozone story takes place. Short-term exposure to current ozone concentrations seems to kill people earlier, as signaled by a new National Research Council report. Ozone is... |

Global or not, a nuclear war would kill us all. And if nuclear weapons didn't do the job, then the Sun would. According to recent studies, a regional global war would cause the ozone layer of the Earth to be destroyed in as little as a decade, all living beings being at the mercy of the Sun's ultraviolet ra... |

Being overweight or obese does not only ruin your inner systems, but also exposes you to external factors. A new research published in the journal Inhalation Toxicology connected higher body mass index (BMI) with increased sensibility to ozone. Short-term exposure to ozone provokes a temporary lung functioning drop i... |

This is not good for life on Earth. The hole in the ozone layer over Antarctica has dropped by 30 % in size in 2007 if we compare it to 2006, as revealed by new data sent by the European Space Agency's Envisat satellite. 0.3 % of the ozone layer mass is lost annually, but fluctuations in its thickness occur thro... |

It is clear that vacuum cleaners have saved us from a lot of effort and time wasted on cleaning our houses. Still, some researches have demonstrated that using this electric appliance too much can decrease the quality of the air we breathe. It appears that the vacuum cleaner expels to the environment particles and mi... |

This is a tricky gas: while protecting life on Earth, ozone can be at the same time a slayer. This gas is constantly forming in a natural way from the oxygen in the atmosphere, while on the ground-level ozone has been increasing due to chemicals emitted by the burning of fossil fuels. The upper atmosphere (stratosphe... |

The ozone's problem was signaled even from the 70s, when the United States intended to open a supersonic fleet between New York and Paris. The researches revealed the destructive effects of the oxides resulted from combustion on the ozone layers. Few years later, researchers concluded that chlorofluorocarbons ar... |

Ozone O3 is an allotrope (variety) of oxygen, much less stable than the generally found O2, and it is responsible for protecting living organisms by preventing damaging long-wavelength ultraviolet light from reaching the Earth's surface.But not all ozone is good.The beneficial one is situated in the upper layer... |
