With containment measures taken worldwide, nitrogen dioxide
concentrations have declined, particularly in Italy and China. In France, some
say they are surprised to hear more birdsong in town.
On Tuesday March 17,
European Copernicus reported that nitrogen dioxide (NO2) levels in the northern
regions of Italy have been reduced due to coronavirus. NO2 shows a trend
towards a gradual reduction of around 10% per week over the past four to five
weeks, according to satellite reports, Copernicus said in a statement.
A map published by
the European Space Agency (ESA) also shows a marked reduction in a red spot
above the Po Valley and in northern Italy between January and March 10.
After the cessation
of part of the Chinese economic activity which had led to the reduction of air
pollution, it is the turn of Europe, and more particularly in Italy, that the
levels of pollution decrease significantly.
When commuting
(home <-> work) and economic activity stop, it's a breath of fresh air
for the atmosphere.
This is the
consequence of the COVID-19 coronavirus pandemic which is literally paralyzing
Europe.
In China, and in Europe, there is a logical drop in pollution following the cessation of all the causes of pollution on land, train, plane, automobile, therefore all types of emissions, and all types of toxic gases.
- New birds have been heard in the cities
- In the ocean, we have no proof but I am sure that cetaceans feel
better (due to the absence of noise and therefore noise pollution is reduced)
- We even think as an environmentalist, that natural phenomena paralyzed until
now by anthropogenic impact, can take shape! and come back to life!
