Recklinghausen (dpa / lnw) - The extensive ban on fireworks and fireworks on New Year's Eve due to the corona measures has had a positive effect on air quality in North Rhine-Westphalia.
The values for nitrogen dioxide (NO2) and fine dust would have turned out a bit after midnight, but “not nearly as much as last year,” said the press spokesman for the Lanuv State Environment Agency, Wilhelm Deitermann, on Saturday for the German Press Agency.
The measured values confirmed that not using fireworks has a positive effect on air pollution control.
When assessing the air values, one always has to keep an eye on the respective weather situation, said Deitermann. On New Year's Eve, there was an inversion weather situation in NRW. “That means that there is very little air exchange. You can always tell when it is very foggy, for example. " The year before there was a similar weather situation, so that the New Year's Eve 2019/20 and 2020/21 are easily comparable. "While in the past few years, under similar weather conditions, the values soared in the first hour of the year, this was largely not the case in NRW this year."
