Effects of tree pollen on throughfall element fluxes in European forests
linear mixed-effects modelling (LME). TF was measured in 1990–2018 during the main pollen season (MPS, arbitrary two months) in 61 managed, mostly pure, even-aged Fagus, Quercus, Pinus, and Picea stands ...
Development of novel analytical methods to trace small micro- and nanoplastics in food matrices
a diameter smaller 1 µm, called nanoplastics (NP s) that could be found in food matrices and environmental samples, by means of specific measurement techniques. Therefore, the aim of this work is to develop ...
Simultaneous Detection and Quantification of Aflatoxin M1, Eight Microcystin Congeners and Nodularin in Dairy Milk by LC-MS/MS
extracted with methanol 80%, followed by an SPE clean-up step before LC- MS / MS analysis. The LOQ was fixed at 1 µg/L for the nine cyanotoxins and 0.05 µg/L for AFM1. Recoveries were measured between 82.67% ...
Daily heart rate characteristics, allergy symptom severity and mood in adults with allergic rhinitis
a mobile health application during two pollen seasons of hazel, alder and birch trees. Heart rate characteristics were extracted from daytime heart rate measurements (Mio Alpha 2 wristwatch; 1 Hz; >6 ...
Quality control and correction method for air temperature data from a citizen science weather station network in Leuven, Belgium
on these intra-urban weather patterns, dense high-quality atmospheric measurements are needed. Crowdsourced weather stations (CWS s) could be a promising solution to realise such monitoring networks in ...
Validity of self-reported data to assess the prevalence of overweight, hypertension and cholesterol
evidence-based prevention programs. In Belgium, this is assessed through self-reported (SR) data from the Belgian health interview surveys (BHIS) in a wide population sample or through objective measures from ...
Validity of air pollution annoyance to assess long-term exposure to air pollution in Belgium
To avoid the risk of exposure misclassification, one possibility is to interpolate air pollution measures at the residence through a Geographical Information Systems. However, this might imply ...
Association between temperature and natural mortality in Belgium: Effect modification by individual characteristics and residential environment
PM2.5 and NO2 while for O3, the effect was lower. Conclusions These findings allow for targeted planning of public-health measures aiming to prevent the effects of extreme temperatures. Health Topics: ...
Higher buccal mtDNA content is associated with residential surrounding green in a panel study of primary school children
sensing derived map. Given the repeated measures design, we applied a mixed-effects model with school and subject as random effect while adjusting for a priori chosen fixed covariates. Results: mtDNAc was assessed ...
What triggers selective daily mobility among older adults? A study comparing trip and environmental characteristics between observed path and shortest path.
older adults (aged 67-94) living in urban and suburban areas of Luxembourg, was measured through detour percentage between their observed GPS-based paths and their shortest paths. Multilevel negative ...
