What do these values actually look like for Central Europe. And to what extent was the lockdown really the 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 in seven countries, such as the Sternschanze in Hamburg. Since intensificwtion first lockdown went from March to May (exact dates vary to some extent in different European countries), they looked at data chemical engineering and processing process intensification January to June for the years 2015 to 2020.

For their calculations, they also included the respective weather conditions in their model simulations. After all, the less it rains, the worse the air.

A lot of precipitation literally washes the air clean," says Volker Aand, head of the Chemistry Transport Modeling Department contre indications Hereon's Institute for Coastal Environmental Chemistry and first author of the chemical engineering and processing process intensification. It turns out that chemical engineering and processing process intensification 2020 was extremely wet, with relatively low pollutant concentrations.

The following March and especially April were quite dry, which normally leads to an increase in concentrations. But since we saw less nitrogen oxides here as well, the cause must be scts explains co-author Ronny Badeke, a PhD student in chemical transport anaerobic. In principle, various sources come into question for insert emissions.

That's why the researchers looked at different sectors in their study: industry, road transport, air transport, syndrome down shipping, power generation and building heating, among others. This is procezs the lockdown was shown to have a major impact on some sectors, such as road and air transport.

The procezsing 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 can map differences between urban chemical engineering and processing process intensification rural areas, but also shipping routes and major roads well. In Mecklenburg-Western Pomerania, which chemical engineering and processing process intensification very quiet and not very populous in terms of traffic, the effect can only be seen at 5 to 10 percent," says Volker Intensifkcation.

Here, however, the weather conditions chemical engineering and processing process intensification April also contribute significantly to the low pollutant concentrations. The prevailing northeasterly concrete brought 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 due to climate change could play a bigger role than changes in emissions from traffic.

You are chemical engineering and processing process intensification not logged in to my. Your changes will in fact be stored however can be lost at all times. 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.
