Personal exposure to traffic-related air pollutants and relationships with respiratory symptoms and oxidative stress: A pilot cross-sectional study among urban green space workers
respiratory/urinary biomarkers (exhaled nitric oxide [NO], 8-hydroxydeoxyguanosine [8- OH dG]). Associations between exposure and health outcomes were investigated using comparison tests and linear regression models, ...
Identification of Flavouring Substances of Genotoxic Concern Present in E-Cigarette Refills
genotoxic substances in e-liquid flavours. 77 e-liquids, representative for the different flavour categories, were collected on the Belgian market and screened for their chemical composition using GC- MS. By ...
Neonatal factors predictive for respiratory and gastro-intestinal morbidity after esophageal atresia repair.
death. We used linear models with a binomial distribution to determine risk factors for gastro-intestinal or respiratory complicated evolution and a backward stepwise elimination procedure to reduce models ...
Plasticizers and bisphenol A, in packaged foods sold in the Tunisian markets: study of their acute in vivo toxicity and their environmental fate.
Then, the identified chemical molecules were studied for their environmental fate and tested in vivo for its toxicity in mice models. The food products analyzed using GC- MS / MS indicated the presence of ...
Coatings in food contact materials: Potential source of genotoxic contaminants?
two structure-activity relationship (SAR) software programs. For substances yielding structural alerts in both models, genotoxicity data were collected from previous European evaluations in a non- FCM ...
Invasion by the Alien Tree Alters Ecosystem Functions in a Temperate Deciduous Forest
general linear models to separate effects of invasion byon heterotrophic soil and litter respiration rates and on canopy foliar nutrient content from effects of soil chemical properties, litter quantity, ...
(Q)SAR tools for priority setting: A case study with printed paper and board food contact material substances.
specific models, as demonstrated here for aromatic azo compounds, typically found in printed paper and board FCM. The strategy developed here can easily be applied to other groups of chemicals facing the ...
Clustering and diagnostic modelling of slimming aids based on chromatographic and mass spectrometric fingerprints
chemometric models can be obtained, based on the presence of prohibited chemical substances, which allow high-throughput data analysis of such samples. Moreover, they generate a prime notion of potential threat ...
Short-term health effects in the general population following a major train accident with acrylonitrile in Belgium.
Fierens; Birgit Mertens; Göen, T; Schettgen, T; Herman Van Oyen; Joris Van Loco; An Van Nieuwenhuyse Source: Environ Res, Volume 148, p.256-263 (2016) Keywords: acrylonitrile Adult Belgium Chemical Hazard ...
Chromatographic impurity fingerprinting of genuine and counterfeit Cialis® as a means to compare the discriminating ability of PDA and MS detection.
270 nm perfect models were gained by PLS- DA and SIMCA, which is very similar to the results obtained for PDA alone. These results show that both detectors have a potential to reveal chemical ...
