China, home of some of the most polluted cities in the world, has received $420 million from a multilateral fund to protect the ozone layer, the official Xinhua news agency said. Some $200 million from a fund set up in 1987 as part of the Montreal pact to protect the …

Developing countries begin freeze on CFCs

With the completion of the grace period granted on signing of the Montreal Protocol on Substances that Deplete the Ozone Layer, developing countries are set to begin, on 1 July 1999, a freeze on production and consumption of chlorofluorocarbons (CFCs), prior to a gradual reduction and final phase-out in the …

Another arrest in national crackdown on CFC smuggling

One of the largest seizures in Texas of the illegal chloroflourocarbon (CFC) Freon took place on 24 June. The seizure, and arrest of Richard Schmolke on charges of smuggling, is part of a national campaign against the CFC black market. Schmolke is charged with scheming to smuggle more than 75,000lbs …

Sun to blame for ozone hole

The hole in the ozone layer in the South Pole is due to the Sun, not people according to research by a Chinese scientist. Yang Xuexiang, a professor of geological sciences at Changchun University of Technology, believes the damage is caused by solar winds, a current of high-energy particles.

Bad news for ozone layer

Scientists at the Max-Plank Institute in Mainz, Germany, have identified another culprit in ozone destruction. Removal of active nitrogen from the gas phase through aerosol-particle sedimentation (denitrification) can substantially increase ozone losses. A Waibel and his team have shown that this loss is particularly significant in the Arctic, where future …

More than unsafe

according to findings of a study commissioned by the European Union ( eu), E uropeans are constantly being exposed to unsafe amounts of ground-level ozone. "The threshold set for the protection of human health is exceeded substantially and in all member states,' reported the Copenhagen-based European Environment Agency ( eea …

Scientists explain ozone losses over Qinghai-Tibet plateau

New studies by Chinese scientists indicate that particular thermodynamic effects have caused ozone depletion over the Qinghai-Tibet Plateau. Zou Han, a researcher from the Institute of Atmospheric Physics of the Chinese Academy of Sciences, said that a recent study shows that the Qinghai-Tibet Plateau is a major geothermal source for …

Environmentalists allege smuggling of CFCs

Smuggling of ozone depleting substances like chlorofluorocarbons (CFC 12) and hydrochlorofluorocarbons (HCFC 22) into India through to the notice of the authorities.Environmentalists have told the authorities that they have evidence to such smuggling and if timely action is not taken to curb smuggling, India would get a bad name since …

India yet to frame laws on ozone depletion

Oxygen additives to gasoline not helping to lower ozone levels

A report issued by a committee of the National Research Council shows that oxygen additives used to reformulate gasoline, required since 1990 by the Clean Air Act, have had little effect in reducing ozone pollution. The U.S. Environmental Protection Agency sponsored a study by the National Research Council, chaired by …

Ozone layer is thickening, says scientists

The ozone layer in the northern hemisphere's upper atmosphere is thicker than it has been for a long time, reports the German Aerospace Research Centre (DLR). "These findings come as a surprise. The ozone layer has not been this thick since the 1980s at least," said nuclear physicist Michael Bittner, …

Commonly available ethanol and MTBE gasoline blends do little to reduce smog

The two principal types of oxygen additives used in reformulated gasoline in the United States contribute little to reduce ozone pollution, says a new report by a committee of the National Research Council.
