The purity of tattoo inks, screening substances of high concern
quantification method was validated to quantify 5-nitro toluidine and 4-chloroaniline in tattoo inks with high accuracy. The method was validated according to the total error approach with an acceptance value of ...
Mapping abundance distributions of allergenic tree species in urbanized landscapes: A nation-wide study for Belgium using forest inventory and citizen science data
citizen science data improves the accuracy of abundance distribution models of allergenic tree species. This produces a continuous, 1-hectare resolution map of alder, birch, and hazel showing spatial ...
WGS- versus ORF5-Based Typing of PRRSV: A Belgian Case Study.
a single ORF is not recommended. Although the typing accuracy can be improved by including multiple regions, our results show that the full genetic diversity among PRRSV strains can only be captured by ...
