Effect of COVID-19 on Environment

The Environmental Blog

Due to air pollution the ozone layer gets depleted and that was nothing but an indication of increasing global warming. The above image shows how much pollution level was in 2019 and hence ozone layer was disappeared. In the above image in 2020 there is an appearance of ozone layer due to the deduction of pollution level.

Less air pollution leads to higher crop yields, says study

Envirotec Magazine

These gases can directly damage crop cells and indirectly affect them through their role as precursors to formation of ozone, an airborne toxin known to reduce crop yields, and particulate matter aerosols that can absorb and scatter sunlight away from crops. Nitrogen oxides, or NOx, are among the most widely emitted pollutants in the world.

Prevention: A profitable mindset when it comes to gas leaks

Envirotec Magazine

CFCs have a high chlorine content and have been linked strongly to ozone depletion and global warming. HCFCs were considered an improvement when they were first introduced, as they have lower chlorine and make a lesser contribution to ozone depletion and global warming. Green hydrogen.

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.

UK Lockdown and air pollution: Nitrogen dioxide halved but sulphur dioxide doubled, says study

Envirotec Magazine

and ozone, and to compare the data to the past seven years. The study appeared to reveal that during this period (from 23 March to 13 June 2020) nitrogen dioxide (NO2) levels were cut by half which would relate to the reduction in vehicle emissions. However, northern cities were found to experience greater increases in sulphur dioxide.

US, China commit to phase down climate-warming HFCs from refrigerators and air conditioners – but what will replace them this time?

Renewable Energy World

CFCs were destroying the ozone layer high in the Earth’s atmosphere, which is essential for protecting life from the Sun’s harmful ultraviolet radiation. But when they break down, they create chlorine that reacts with the protective ozone, letting dangerous radiation through to the Earth’s surface. Why HFCs are a climate problem.
