It is not possible to look at it: terraces are full of dirty garden furniture and the roads are full of dirty cars. This is mainly due to the persistent drought and the amount of pollen in the air.
It has been dry for weeks in our country and experts have been advising water to spray the lawn and brush cars and garden furniture. Annoying, especially now that it is becoming more and more visible how dirty they are.
The obvious explanation is the lack of precipitation and the bone -dry soil that is the result of it. « That means that there is a lot of dust on that bottom that blows up when there is some wind, » says Frans Fierens of the inter -regional cell for the environment. « That is coarse dust, so that quickly becomes visible when it stabs. In contrast to fine dust, which is much smaller. But those concentrations in the air are not that high at the moment. »
According to Astha Tiwari from Sciensano, everything is mainly due to the large amount of pollen in the air. “They mainly come from trees from the pine family (Pinaceae). Those pollen are relatively large, yellow in color and remain easily visible on smooth surfaces such as car windows. Our recent measurements show that the number of pollen grains in Brussels have reached a peak of about 600 grains per cubic meter. period of the year, when trees from the pine family release their pollen en masse. «
Given the drought and the concern that is there for water supply, Frank Deboosere recommends not to brush your car immediately when it is dirty. « Of course you have to be able to look through the windows, but feel free to waste the body, » he says. Wait better for all the dust to rains, he recommends. Although you may have to be patient for at least a week. « It is possible that it is raining here and there today or tomorrow, but only next week does it seem to come really rain. »
