Geological reasons of ozone layer destruction
October 19, 1999The modern science admits that the ozone concentration in the stratosphere is diminishing. This process has been fixing since the middle of 1980s. "The most popular hypothesis about technogenic freon that destroys the ozone layer is quite vulnerable", - said Dr. of geology Vladimir Sivorotkin who studies the problem of the ozone layer for ten years.
Freon is used mainly as a vaporising fluid in the foam material production and as a coolant in the refrigerating units. According to technogenic-freon hypothesis all technical freon gets to stratosphere where on high 20-25 km the ozone layer exists. In the stratosphere under the ultra-violet irradiation the chlorine that is part of freon reacts with ozone and destroys it. However, there is a contradiction here. Thus, the largest ozone hole lies above the Antarctic regions whereas basic sources of technical freon are in the Northern Hemisphere. The results of a study of nuclear test product movement show that the exchange between air masses of both hemispheres is difficult. Moreover, predictions of the technogenic-freon hypothesis are not accurate though it has at its disposal all data of technical freon production.
Vladimir Sivorotkin has developed an alternative hypothesis according to which the ozone layer is diminished by natural reasons. It is well known that the ozone-by-chlorine destruction cycle is not unique. There are nitrogen and hydrogen cycles of the ozone destruction too. Hydrogen is "basic gas of Earth". Its main resources are concentrated in the Earth interior and get to the atmosphere through the system of faults (rifts).
V.Sivorotkin emphasises that ozone holes lie above the centres of hydrogen degasation of the Earth. Now the system of rifts is well studied by geologists that makes it possible to predict places of ozone holes. Thus, the ozone hole above the Antarctic lies there constantly because main degasation channels - mid-oceanic rifts - draw nearer around the Antarctic and increase "the hydrogen blowing of atmosphere" there. Taking into account a seismic activity enlarging the Russian scientist predicted an appearance of a large ozone hole above the equatorial region of Pacific east part (January 1998).
According to V.Sivorotkin, the progressing diminution of Earth ozone layer is directly connected with an intensification of Earth degasation. However, the reasons of this intensification are not clear.

Ozone Current Events and Ozone News RSSOceans' uptake of manmade carbon may be slowing
The oceans play a key role in regulating climate, absorbing more than a quarter of the carbon dioxide that humans put into the air.
Tiny bubbles clean oil from water
Small amounts of oil leave a fluorescent sheen on polluted water. Oil sheen is hard to remove, even when the water is aerated with ozone or filtered through sand.
A bubbling ball of gas
The Sun is a bubbling mass. Packages of gas rise and sink, lending the sun its grainy surface structure, its granulation. Dark spots appear and disappear, clouds of matter dart up - and behind the whole thing are the magnetic fields, the engines of it all.
Nitrogen loss threatens desert plant life, study shows
As the climate gets warmer, arid soils lose nitrogen as gas, reports a new Cornell study. That could lead to deserts with even less plant life than they sustain today, say the researchers.
Researchers discover links between city walkability and air pollution exposure
A new study compares neighborhoods' walkability (degree of ease for walking) with local levels of air pollution and finds that some neighborhoods might be good for walking, but have poor air quality.
Interactions with aerosols boost warming potential of some gases
For decades, climate scientists have worked to identify and measure key substances -- notably greenhouse gases and aerosol particles -- that affect Earth's climate.
Report examines hidden costs of energy production and use
A new report from the National Research Council examines and, when possible, estimates "hidden" costs of energy production and use -- such as the damage air pollution imposes on human health -- that are not reflected in market prices of coal, oil, other energy sources, or the electricity and gasoline produced from them.
Air pollutants from abroad a growing concern, says new report
Plumes of harmful air pollutants can be transported across oceans and continents -- from Asia to the United States and from the United States to Europe -- and have a negative impact on air quality far from their original sources, says a new report by the National Research Council.
U.S. needs nearly $200 million more on climate-related health research
A recent commentary suggests that the U.S. should spend roughly $197 million more than it currently does to research the impact of climate change on public health.
Ozone layer depletion levelling off
By merging more than a decade of atmospheric data from European satellites, scientists have compiled a homogeneous long-term ozone record that allows them to monitor total ozone trends on a global scale - and the findings look promising.

3Q Electrostatic Ionic Air Purifier by 3Q INTERNATIONAL This is an electronic air purifier. It uses what is known as an ionizer to filter out the dirty air. The electronic air purifiers have two sections for getting rid of dirty air. One section is for ionizing and the other section is for collecting the dirt. In the ionizing section, dirty air particles pass between ionizing wires and plates connected to a high voltage power supply. Over 8000 volts ionizes the air, creating positive ions which attach to the particles leaving them with an intense electrical charge. The charged particles then move to the collection section, where they encounter closely-spaced, oppositely-charged collector plates. Positively-charged particles attach to the negative plates and negatively-charged particles attach to the positive plates. Negative ions are important... |

OZONE A New Medical Drug by Velio Bocci (Author) Oxygen-ozone therapy is a complementary approach less known than homeopathy and acupuncture because it has come of age only three decades ago. This book clarifies that, in the often nebulous field of natural medicine, the biological bases of ozone therapy are totally in line with classic biochemical, physiological and pharmacological knowledge. Ozone is an oxidising molecule, a sort of superactive oxygen, which, by reacting with blood components, generates a number of chemical messengers responsible for activating crucial biological functions such as oxygen delivery, immune activation, release of hormones and induction of antioxidant enzymes, which is an exceptional property for correcting the chronic oxidative stress present in atherosclerosis, diabetes, infections and cancer. Moreover... |
