This year’s ozone hole could be the smallest it has been in 30 years

AGreenLiving

For decades, scientists have closely observed the ozone layer , which protects Earth from the sun’s harmful ultraviolet (UV) radiation. Ozone is created in our atmosphere when the sun’s high-energy UV rays rupture the stable covalent bonds of atmospheric oxygen (O2) molecules, transforming them into free radicals.

UK substantially underestimates its methane emissions from oil and gas production – and many other countries probably do too

Envirotec Magazine

Due to its climate and indirect health impacts (methane is a precursor for ozone which is an air pollutant that damages human health and crops), methane mitigation has recently become a global policy priority. These updates resulted in a total methane emission estimate more than five times larger than reported emissions.

The Environmental Impact Of Biomedical Waste And How To Reduce It

The Environmental Blog

Best practices for biomedical waste management include regular training and education of staff, the use of personal protective equipment, and proper documentation of waste management activities. Another approach is to use alternative technologies for treatment and disposal, such as microwave or ozone treatment.

China’s new frontier for VOC regulations

GreenBiz

Volatile organic compounds (VOCs) combine with nitrogen oxide to create ozone, a key precursor to smog. When energy use surges in the autumn and winter seasons, particulate matter and ozone increase to dangerously high levels. In a PDP, the maximum volume of VOC emissions that a factory can emit is stated. Environmental capacity.

Risk, doubt, and the burden of proof in the climate debate

GreenBiz

There is no need to reduce carbon dioxide emissions and no point in attempting to do so," as one recent Heartland document succinctly put it. More often, it is implicitly built into the conversation, as it was in so many other public debates, like those over leaded gas, ozone and tobacco.

How stable isotopes help the fight against air pollution

Envirotec Magazine

It is well documented that the UK has a poor reputation when it comes to air quality regulation. particles derived from fossil fuel burning, ozone and volatile organic compounds, such as sulphate aerosols and nitrous oxides, which play a major role in causing worldwide issues with air quality. This includes sub-micron PM 2.5
