Automatic detection of airborne pollen: an overview
Buters, Jeroen; Clot, Bernard; Gálan, Carmen; Gehrig, Regula; Gilge, Stefan; Hentges, François; O´Connor, David; Sikoparija, Branko; Skjoth, CarstenPollen monitoring has traditionally been carried out using manual methods first developed in the early 1950s. Although this technique has been recently standardised, it suffers from several drawbacks, notably data usually only being available with a delay of 3–9 days and usually delivered at a daily resolution. Several automatic instruments have come on to the market over the past few years, with more new devic...
The role of automatic pollen and fungal spore monitoring across major end-user ...
Tummon, Fiona; Adams-Groom, B.; Antunes, Célia; Bruffaerts, Nicolas; Buters, Jeroen; Cariñanos, Paloma; Celenk, Sevcan; Choël, M.; Clot, BernardThe advent of automatic pollen and fungal spore monitoring over the past few years has brought about a paradigm change. The provision of real-time information at high temporal resolution opens the door to a wide range of improvements in terms of the products and services made available to a widening range of end-users and stakeholders. As technology and methods mature, it is essential to properly quantify the i...

Challenges in Nanomaterials Safety Assessment: Insights from Titanium Dioxide
Bettencourt, Ana; Santos, Rita; Ribeiro, HelenaNanomaterials (NMs) hold immense potential for innovation in healthcare, but their safe use requires evaluation through all stages of product research and development. Scientific literature is a crucial resource for assessing NMs safety, yet extracting and analyzing this information presents significant challenges. In this context, the objective of this study was to illustrate the application of the Ishikawa di...
Outdoor airborne allergens: Characterization, behavior and monitoring in Europe
Grewling, Lukasz; Ribeiro, Helena; Antunes, Célia; Apangu, Godfrey; Çelenk, Sevcan; Costa, Ana; Eguiluz-Garcia, Ibon; Galveias, Ana; Roldan, NestorAeroallergens or inhalant allergens, are proteins dispersed through the air and have the potential to induce allergic conditions such as rhinitis, conjunctivitis, and asthma. Outdoor aeroallergens are found predominantly in pollen grains and fungal spores, which are allergen carriers. Aeroallergens from pollen and fungi have seasonal emission patterns that correlate with plant pollination and fungal sporulation...
The impact of noise exposure in Air Force Military
Correia, Mariana; Matos, Teresa; Ribeiro, Helena; Lopes, Marina; Almada, SofiaIntroduction: Military aviation is characterized by multiple noise sources, which are worrying as they exceed the legal limits required. The objective of this study is to evaluate the need to extend the monitoring program for all military exposed to aviation noise in the Air Force Units, with the specific objectives of evaluating the noise level to which they are exposed during the day and assessing the impact ...
