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 ...
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% ...
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 ...
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 ...
Changes in physical activity by context and residential greenness among recent retirees: Longitudinal GPS and accelerometer study.
Place, Volume 73 (2021) Abstract: This study examined the changes in accelerometer-measured physical activity by GPS-measured contexts among Finnish retirees (n = 45 (537 measurement days)) participating ...
Converting Raw Accelerometer Data to Activity Counts Using Open-Source Code: Implementing a MATLAB Code in Python and R, and Comparing the Results to ActiLife
Publication Type: Peer reviewed scientific article Authors: Ruben Brondeel; Yan Kestens; Javad Rahimipour Anaraki; Kevin Stanley; Thierry, Benoit; Daniel Fuller Source: Journal for the Measurement ...
4DEMON: Integrating 40 Years of Data on PCB and Metal Contamination in Marine Sediments of the Belgian Part of the North Sea
different grain size fractions were analyzed, appropriate co-factors were not always analyzed, and measurement uncertainties were not always indicated. These issues hampered the use of readily available, ...
In utero exposure to parabens and early childhood BMI z-scores – Associations between placental ethyl paraben, longitudinal BMI trajectories and cord blood metabolic biomarkers
butyl (BuP)] were measured by ultra-performance liquid chromatography/tandem mass spectrometry in 229 placentas of the ENVIRONAGE birth cohort. The association with cord blood metabolic biomarkers ...
