The impacts of climate change and meteorological factors on pollen season indicators of allergenic plant taxa
Pollen respiratory allergies have been increasing in prevalence over the last two decades, partly as the result of the impact of climate change. For many allergenic trees, grass and weed species, increased pollen production and prolonged pollination period result in long-term increased abundance of pollen allergens in the atmosphere; earlier shifts of airborne pollen grains and prolonged exposu...
متن کاملA new software-based characterisation of the pollen season by using climate specific pollen indicators
The EU Strategy on adaptation to climate change (2013) called the attention that climate change might potentially increase the seasonality and duration of allergic disorders like hay fever or asthma. Because it is of high importance to evaluate the pollen exposure of population living in different geographical and climatic regions in order to adjust information and adaptive measures, tools for ...
متن کاملAnthropic pollen indicators: poaceae pollen of non-native species in Southern Brazil
The identification of environmental changes by human action in the past is crucial for recovery plans and preservation of natural areas. Changes of the landscape (by human action) and natural shifts of vegetation can be showed by pollen records analysis. In this sense, pollen description of modern plants is important for use as a database for the identification of pollen samples of past. The in...
متن کاملThe Effect of Physical Activity on Attention Indicators of Schoolchildren
Background. Sedentary lifestyle of schoolchildren has a negative impact not only on physical abilities, but also on mental processes. The relationship between physical activity of schoolchildren and indicators of their attention has not been studied in depth. Objectives. To determine the effect of physical activity in physical education lessons on the attention indicators of children 15-16 yea...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
