Population vulnerability to COVID-19 in Europe: a burden of disease analysis

their country, or national burden of disease studies that also use sub-national levels for burden quantifications, should consider using non-fatal burden of disease estimates to estimate geographical ...

Determinants of persistent organic pollutant (POP) concentrations in human breast milk of a cross-sectional sample of primiparous mothers in Belgium

compounds (p,p′- DDT, p,p′- DDE, HCB and β- HCH) and two brominated flame retardant congeners (BDE-47, BDE-153) were detected at concentrations above the limit of quantification in >50% of the breast milk ...

Characterization and hazard identification of substandard and falsified antimicrobials encountered in Belgium

quantification of active pharmaceutical ingredients (API s) potentially present in these suspicious SF antimicrobials, are paramount. Here, a validated ultra-high performance liquid chromatography-tandem mass ...
