Simply as winter pollens (reminiscent of cypress, ash and hazel) have been delayed by the winter chilly, stopping vegetation from beginning to launch important quantities of pollen till early March, the springs will even undergo a setback because of the current episode of low temperatures. In neither case is it excellent news. Bushes reminiscent of cypress, which have collected massive quantities of pollen, might now out of the blue launch it in very excessive focus peaks, inflicting individuals who have by no means suffered from allergy symptoms to now develop them. Additionally, between subsequent week and the final week of March, the shade plantain and the parietaria, for instance – each of that are spring pollinated and extremely allergic – might start to launch important quantities of pollen len. That is what the researchers of the Institute of Environmental Science and Know-how of the Autonomous College of Barcelona (ICTA-UAB) predict, who yesterday offered the pollen forecast for spring in Catalonia.
"This winter, with the climate, the vegetation that pollinate on this season have hardly performed so, however they've produced flowers that are actually loaded with pollen and that in different years they'd been releasing it" , explains to La Vanguardia Jordina Belmonte, ICTA-UAB researcher and head of the Aerobiology Community of Catalonia (XAC). "What can occur - he continues - is that bushes just like the cypress out of the blue launch quite a lot of pollen and there are crucial peaks. People who find themselves already allergic is not going to be harmed by the discharge of extra pollen, as a result of they'll have already got been affected primarily based on the quantity their physique reacts to. However, then again, it will possibly occur that those that had by no means suffered from this allergy, as a result of there can be a lot pollen within the air, turn out to be allergic". Because of this, he advises these people who find themselves extra delicate to winter vegetation to "watch out, as a result of this state of affairs can occur". And what could be performed to attenuate the signs? To start with, get away, if doable, so far as doable from this kind of tree, Belmonte factors out. It's also advisable to make use of masks, "to scale back the quantity of allergen that reaches them", in addition to sun shades.
Alternatively, the climate fashions point out that the spring can be barely hotter than ordinary and that the month of April can be wet. With this data, the forecast of the degrees of pollen and spores within the ambiance in Catalonia for the approaching months by the XAC signifies that the spring pollinations (buckthorn, plantain, pine, parietaria, willow, maple, mulberry bushes, grasses and later these of birch, white wheat, massive plantation and olive tree) will proceed with the tendency to start out with a sure delay, however strongly, and will have a shorter period than ordinary. "When the temperature is larger, pollinations are likely to final much less", argues Belmonte. As well as - he continues -, "if it rains in April and it occurs in the course of the day, when there's gentle and the vegetation emit pollen, the rain would carry it to the bottom and take away it from the air". In line with the XAC, probably the most plentiful kinds of allergenic pollen basically within the ambiance of Catalonia are: cupressaceae (20.8%), reminiscent of cypress; the shadow banana (9.7%); oleaceae (8.6%), such because the olive tree; parietaria (5.3%) and grasses (4.3%) and white wheat (2.4%), with important variations in keeping with the geographical and climatic zones of Catalonia. The spores of the alternaria fungus, regardless of their impression on allergy symptoms, are usually not probably the most plentiful.
