Ozone

When looking for planets with extraterrestrial life, look for low carbon dioxide and high ozone, says a new study

Earth's protective ozone layer is slowly but noticeably healing at a pace that would fully mend the hole over Antarctica in about 43 years, a new United Nations report says.

However, according to Canadian researcher Ching-Bin Lu, it has been around since the 1980s. It is estimated that the hole has existed since the eighties, but only now has its large size been realized.

The number of early deaths caused by air pollution in Greece is nearly double the European Union average, according to research.

Data from the European Environment Agency show that there were 16,440 early deaths in Greece in 2016 due to exposure to fine particulate matter (PM2.5), nitrogen dioxide (NO2) and ozone (O3). 

The cleanliness of the air will be able to be tracked completely online in real time. The metropolitan municipality presented its own monitoring system. It started operating today. The aim is to be a natural extension of the systems of citizens' initiatives for air pollution.

This year, the ozone hole near the South Pole is smaller than when it was discovered, This, however, is due to the Antarctic weather being whimsical rather than the effort to reduce pollution, the AP reported, citing NASA.

The ozone hole over Antarctica is the smallest in almost 30 years. According to the U.S. Atmospheric Administration, this year its size is twice smaller than usual. In addition, it is located far from the pole, unlike before.

Observations of the gas's depletion high in the atmosphere demonstrate that it hasn't opened up in 2019 in the way it normally does, BBC reported.

This is according to a study by scientists from the United States and Denmark.

Scientists from the United States and Denmark have proven that the risk of mental illness depends on the quality of the air, and Chinese scientists add that temperature fluctuations also have effect on our mental health. 

The ozone hole has shrunk thanks to the ban on harmful chemicals. This is clear from a NASA study, Nova TV reported.

Rising ozone pollution in China's cities has emerged as a major health risk, causing a rise in deaths from strokes and heart disease among vulnerable residents, according to a new study by a team of Chinese researchers.
