New laboratory to study the oceans and air
November 21, 2003Almost two-thirds of the planet is ocean and this has a major impact on our lives. Now the University of East Anglia (UEA) will be home to the world's first facility dedicated to the study of chemical ocean-air interactions which are important in regulating Earth's climate.
Examples include ocean uptake of greenhouse gases such as carbon dioxide and production of tiny atmospheric particles from gases emitted by marine algae which can have large impacts on climate. To date there has been little research on these kinds of exchanges particularly in remote ocean areas.
"Greenhouse gas emissions and ozone depletion are now recognised threats, these new facilities will help us to address some of these problems and answer some of the current unknowns," said Professor Tim Jickells, Director of the Laboratory for Global Marine and Atmospheric Chemistry (LGMAC).
LGMAC houses state-of-the-art facilities including an ultra-clean laboratory for the study of air and water composition, measuring minute quantities free from the impact of local pollution such as car fumes. There is also a specialist laboratory for the use of lasers to study atmospheric chemical reactions.
A trace gas laboratory in LGMAC, with simulated Antarctic conditions, will allow the study of ancient ice cores. These ice cores contain tiny trapped bubbles of air, which when released can tell us more about past climatic conditions, in turn helping improve predictions of future climate.
The LGMAC facilities, worth £7m, were funded through a successful bid to the Government's Joint Infrastructure Fund (JIF).
The Laboratory for Global Marine and Atmospheric Chemistry will be opened on Friday November 28 by Nobel Prize-winner Professor Paul Crutzen. Professor Paul Crutzen shared the 1995 Nobel Prize for Chemistry for his work on atmospheric chemistry, particularly the formation and decomposition of ozone.

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.

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... |

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... |
