Occurrence of microcystin congeners in surface waters and food in Belgium as a source of exposure to humans

analyzed, whereof nine samples contained MC s. Moreover, three samples exceeded the concentration of 1 µg g−1 total microcystins, previously proposed as a guideline value. Microcystis sp. were determined as ...

Development of strain-level shotgun metagenomics approaches to detect and characterize microbiological contaminants in the context of food safety

Enteritidis strain linked to the outbreak could be obtained, fully characterized, and related to the food and human isolates from the outbreak in a phylogenetic tree containing other Belgian sporadic cases and ...

Development of vibrational spectroscopic methods combined with chemometrics for the detection and quantification of nicotine in e-liquids.

nicotine-containing e-liquids via the internet. The ban on long-distance sale implies that postal packages containing e-liquids are checked at customs. Furthermore, there is a demand of vapeshop-inspectors for on-site ...

Chemical and toxciological characterization of e-liquid cigarettes

nicotine-containing e-cigarettes became freely available on the market and ‘vapeshops’ skyrocketed since then. As the number of e-cigarette users increased, so did the media coverage about the benefits and dangers of ...

Bepaling van spoorelementen in diverse matrices met spectrometische technieken.

has shown that Ti nanoparticles are contained in the fibers. Conclusion Only low concentrations of trace elements were found in most of the food enzyme preparations studied. The information collected ...

Genotoxic evaluation of the liquids present in electronic cigarettes

assess the applicability of the in vitro tests for the e-liquid mixtures, three 2,3-pentanedione-containing e-liquids (i.e. Nutella Shake, Hyprtonic Mercedes, Miller’s Chocolate) and an e-liquid containing ...

Study of the possible migration risks of food contact materials for children under 3 years

(de)protonated molecule and fragment ions were acquired simultaneously. Data were automatically processed using a homemade database containing around 1200 chemicals present on the list provided by the EU ...

Detection and risk evaluation of counterfeit medicines based on physico-chemical properties: the fingerprint and chemometrics approach

distinguish between counterfeit medicines containing a different API. This shows that chemometric analysis of ATR- FTIR fingerprints is a valuable tool to discriminate genuine from counterfeit samples and to ...

Development of a generic and open source Incidence-Prevalence-Mortality model for the assessment of chronic disease epidemiology

on case fatality, prevalence, and relative risk mortality were produced using only inputs on incidence, remission, and mortality. In addition, the function also produced various objects that contained ...
