Relationship between Climate Change, Air Pollution and Allergic Diseases Caused by (Common Ragweed).

Influence of climate change and outdoor air pollution (through anthropogenic factors, including heavy traffic, industry and other human activities polluting the environment), which contribute to global warming and increase the allergenicity of some plants (common ragweed) on allergenic patterns, with a direct negative impact on human health, causing or exacerbating allergic respiratory diseases such as bronchial asthma and allergic rhinitis, changing the pattern of respiratory tract infections and premature deaths in Europe. The present study aims to highlight the link between climate change, outdoor air pollution, altered allergenicity of palms and possible behavioural risk factors in the environment. The clinical studies selected in this research highlighted the links between climate change, air pollutants and the occurrence/exacerbation of aeroallergen-induced respiratory disease; climate change (as an inducer of allergic respiratory disease), increasing global mean ambient air temperature and aeroallergens; climate change, global warming, [CO₂] concentration and aeroallergens; climate change, atmospheric humidity, dust storms and aeroallergens; urbanisation (anthropogenic influence), air pollution and aeroallergens; potential of different plant species (common ragweed) for Ni accumulation and possible effects on the human body.

PM10 and NO2 Air Pollution and Evolution of COVID-19 Cases in Romania.

Based on the correlation between air pollution and COVID-19 incidence/mortality already existing in the literature, we aimed to develop a study to investigate the link between the average level of PM10 (particulate matter 10 - particulate matter 10 microns in diameter) and NO2 (nitrogen dioxide) concentration over five years and the cumulative incidence of COVID-19 cases 1000 people in Romania. To assess PM10 and NO2 exposure, we determined the average value of annual PM10 and NO2 concentration for each city over five years (2015-2019). For this purpose, the average of annual PM10 and NO2 concentrations collected from monitoring stations in selected cities was calculated.
