Reappraising assumptions about ozone in European cities

Envirotec Magazine

Ozone levels near the surface in urban environments are lower than expected, in the results of an Austrian research group The 40-meter-high monitoring tower of the Innsbruck Atmospheric Observatory near the centre of the city of Innsbruck continuously provides data on the composition of the atmosphere at ground level.

The Hydrogen: Sustainable Boost for Ozone Layer Preservation

FuelCellsWorks

Hydrogen itself does not have a direct role in ozone layer preservation, but it can contribute to its protection by providing an alternative and clean source of energy when used.

What’s the latest with the ozone layer?

Envirotec Magazine

On 16 September, the world marked the International Day for the Preservation of the Ozone Layer. The European Space Agency (ESA) takes a closer look at this year’s ozone hole. The ozone layer in the atmosphere protects Earth from potentially harmful ultraviolet radiation. Ozone depletion is greatest at the South Pole.

The global treaty to save the ozone layer has also slowed Arctic ice melt

Grist

The 1987 Montreal Protocol, which phased out the production and use of chemicals that were depleting the ozone layer, has long been considered one of the most successful environmental treaties in history. The Montreal Protocol was created to address a hole in the stratospheric ozone layer over the Antarctic. In a 2022 report , a U.N.

What are ‘planetary boundaries’ and why should we care?

Envirotec Magazine

We’ve done it already in the 1990s, when international cooperation quickly phased out ozone-depleting chemicals and stopped the dangerous ozone hole from getting ever-bigger. We are still in the green for ozone-depleting chemicals. Three are based on what we take from the system: biodiversity loss fresh water land use.

Study flags night-time air pollution in China as potential health threat

Envirotec Magazine

China is a night-time ‘hot-spot’ for the production of nitrate radicals (PNO3) that could have a major impact on health-threatening ozone and fine particulates (PM2.5) The study seems to show that, if recent increasing ozone pollution trends continue, nighttime oxidation in China will increase further even if NOx emissions are reduced.
