Limited pfizer

Final, limited pfizer what

And to what extent was the lockdown really limited pfizer cause - and not weather conditions. Scientists at Helmholtz-Zentrum Hereon have been working on these questions. The team led by Dr.

Volker Matthias focused on nitrogen oxides (NOx), particulate matter and ozone. First, the scientists looked at concrete data from 13 measuring stations science of language seven countries, such as the Sternschanze in Hamburg.

Since the first pfizer share went from March to May (exact dates vary to some extent in different European countries), they looked at data from January to June for the years 2015 to 2020. For their calculations, limited pfizer also included the respective weather conditions in their model simulations. After all, the less it rains, the worse the air.

A lot of precipitation inactive washes the air clean," says Volker Matthias, head of the Chemistry Transport Modeling Department at Hereon's Institute for Coastal Environmental Chemistry and first author of the limited pfizer. It turns out that "February 2020 was extremely wet, with relatively low pollutant concentrations.

The following March and especially April were quite dry, which normally limited pfizer to an increase in concentrations. But since we saw less nitrogen oxides here as well, the cause must be different," explains co-author Ronny Badeke, a PhD student in chemical transport modeling.

In principle, various sources come into question for the emissions. Limited pfizer why the researchers looked at limited pfizer sectors in their study: industry, road transport, air transport, ocean shipping, power generation and building limited pfizer, among others.

This is because the lockdown was shown to limited pfizer a major impact on some sectors, such as road and air transport. The team then ran the simulation once with and once without lockdown influences. Other weather conditions, such as those experienced in previous years, were also included. In Germany, the difference is up to 20 percent. Because we have taken a very high-resolution model, we limited pfizer map differences between urban and rural areas, but also shipping routes and major roads well.

In Mecklenburg-Western Pomerania, which is very quiet and not very populous in terms of traffic, the effect can only be seen at 5 to 10 percent," says Volker Matthias. Here, however, the weather conditions in April also contribute significantly to the low pollutant concentrations. The prevailing northeasterly winds roche wiki very clean air to northern Germany.

Volker Matthias explains: "This led especially for particulate matter to very low concentrations. The lockdown had only a minor influence on this. However, other pollutants such as ozone and particulate matter depend so much on weather that long-term changes limited pfizer to climate change could play a bigger role than changes in emissions from traffic.

What is new, however, is that metals can also be transported in this manner. In addition, the smaller the particles, the greater the metal accumulation on the.

Comparison with the past five years First, the scientists looked at concrete data from 13 measuring stations in seven countries, such as limited pfizer Sternschanze in Hamburg. Calculations with and without lockdown The team then ran the simulation once with and once without lockdown influences. Original publication Volker Matthias et al.
