The 2011 tsunami that struck Japan released thousands of tons of ozone-destroying chemicals and greenhouse gases into the air.

The ozone hole above the Antarctic has hit its maximum extent for the year. Due to warm temperatures, the opening in the protective atmospheric layer was the se

Good news from Antarctica: The hole in the ozone layer is shrinking, new measurements reveal.

The worldwide ban on ozone-depleting chemicals stopped Arctic ozone from disappearing and forming an "ozone hole" similar in size to Antarctica's.

Loopholes in the Montreal Protocol may need to be tightened, researchers say.

The hole in the ozone layer over Antarctica is nearing record-breaking size again, scientists say.

The hole over Antarctica is slowly healing, but research suggests the ozone layer is thinning at lower latitudes.

Six years of monitoring for ozone injury by the Pacific Northwest Research Station Forest Inventory and Analysis Program are reported. The methods used to evaluate injury, compute an injury index, and estimate risk are described. Extensive injury was detected on ozone biomonitoring sites for all years in California, with ponderosa and Jeffrey pines, mugwort, skunkbush, and blue elderberry showing injury. Little or no injury was detected in Oregon and Washington. The relation of observed injury to ambient ozone levels is discussed. The areas with the highest modeled risk of ozone injury are the areas east of Los Angeles, the southern Sierra Nevada, and portions of the central coast.

A two step process for the destruction of a precursor material using a steam plasma in a three zone reactor wherein the precursor material is hydrolyzed as a first step in the high temperature zone of the reactor, followed by a second step of medium temperature oxidation of the reactant stream in the combustion zone of the reactor where combustion oxygen or air is injected and immediate quenching of the resulting gas stream to avoid the formation of unwanted by-products. A related apparatus includes a non transferred direct current steam plasma torch, an externally cooled three zone steam plasma reactor means for introducing the precursor material into the plasma plume of the plasma torch, means for introducing the combustion air or oxygen into the combustion zone, means for exiting the reactant mixture from the reactor and means for quenching the reactant mixture located at the exit end of the reactor.

System for application of ozone on grains made up essentially by one or more ozone mixers with particulates separator (1) for injecting air in the grains mass, one or more ozone mixers (2) for injecting air in the grains mass, a base of the device for grains treatment with ozone (3), a transport and discharge device (4), and an air cooling filter (5) that can be used individually or jointly to apply ozone on the grains mass.

A method for producing ozone is disclosed. The ozone is separated by an adsorbent separation system from a mixture of oxygen and ozone. The adsorbent separation system operates by adsorbing ozone at higher pressures, then desorbing the ozone at normal pressures. Increased ozone concentrations result from these steps while the oxygen component can be recovered and used in producing the mixture of oxygen and ozone.

Provided is a method for reducing COD of wastewater with improved utilization efficiency of ozone. The method achieves an objective by adding agents for removing hydroxyl radical scavengers produced by base-catalyzed ozone advanced oxidation to wastewater. The addition of calcium ion, barium ion, etc. to a base-catalyzed ozonation system makes the hydroxyl radical scavengers form precipitates, separated from water and lose the capability of scavenging hydroxyl radicals, thereby enhancing ozone utilization efficiency. Furthermore, calcium ion, barium ion, etc. form precipitates with partial organic acids yielded in the wastewater ozonation and are separated from water, hence diminishing ozone consumption and indirectly improving the ozone utilization efficiency in the wastewater treatment. The present invention can not only significantly enhance the reaction rate and utilization efficiency of ozone, saving reaction time and costs, but also enable complete mineralization of the organic compounds, significantly reducing COD and total phosphorus of wastewater.

A method for treating contaminated liquids in a flow by ozone, wherein the ozone is fed in gas form into the flow at one point and then is mixed into the flow in stages by mixers following one another in the flow direction, so that an absolute quantity of introduced ozone increases after each mixer until a feed efficiency of more than 95 percent is reached.

The euro area private sector experienced a record downturn in April due to the severe disruption caused by the coronavirus, or covid-19, pandemic, final survey results from IHS Markit showed Wednesday. The composite output index slid to a new series low of 13.6 from March's 29.7. The flash score was 13.5. Both manufacturing and services reported record fall in output in April.

European Central Bank Vice-President Luis de Guindos and Governing Council member Gabriel Makhlouf said separately on Thursday that the central bank was more determined to support the euro area economy during crisis periods and the bank stands ready to adjust all tools at its disposal, just days after the top German court ruled that the bank's government debt purchases were in violation of its mandate.

As global climate change leads to more hot and dry weather, the resulting droughts are stressing plants, making them less able to remove ozone — which at ground level is a dangerous pollutant — from the air.

Eurozone ministers have formally approved €240 billion in credit lines to help European countries meet the crippling costs of fighting the coronavirus outbreak.

Rising HFC use poses a significant threat to intergovernmental efforts to combat climate change. At present, there is a glaring regulatory gap in this area. Although challenging, there is no reason why the international community cannot come together to address this new problem of coordination and ensure that legal regimes support each other.

Sudden stratospheric warming it's great for the ozone layer at the South Pole, but not so great for heat and rain levels over the next few months.

BASF Corporation has agreed, under a Clean Air Act settlement filed today in federal court in Beaumont, Texas, to reduce the use of refrigerant chemicals that destroy the earth’s stratospheric ozone layer.

Dov Shellef, a businessman from Great Neck, N.Y., was convicted today on 86 counts, following a five-week jury trial, for conspiring to defraud the Internal Revenue Service in the collection of approximately $1.9 million in excise taxes due on sales of the ozone-depleting greenhouse gas known as CFC-113.

In a settlement agreement with the United States, Safeway, the nation’s second largest grocery store chain, has agreed to pay a $600,000 civil penalty and implement a corporate-wide plan to significantly reduce its emissions of ozone-depleting substances from refrigeration equipment at 659 of its stores nationwide, estimated to cost approximately $4.1 million.

Costco Wholesale Corporation, one of the nation’s largest retailers, has agreed to cut its emissions of ozone-depleting and greenhouse gases from leaking refrigeration equipment at more than half of its stores nationwide.

Ozone — best known for filtering out harmful UV light as a component of the Earth's stratosphere — could dramatically reduce plants' ability to act as a carbon sink and thus cause further accumulation of greenhouse gases in the atmosphere, according to

We recently told you of a study warning that global warming could prompt the large-scale collapse of the world's crops by 2080; now comes another study concluding that rising levels of ozone could achieve the same result by century's end. The study,

Talk about a lose-lose situation: On one hand, not taking any action to repair the hole would allow harmful UV radiation to percolate through; on the other hand, helping to accelerate its recovery could strengthen global warming by
