Bioavailability and exposure to cadmium from chocolate consumption: a nutritional study KU Leuven
Since 2019, new European limits apply to cadmium (Cd) in cacao-derived products. These limits largely affect the South American cacao industry, where Cd concentrations in cacao beans are naturally large. The basis of the regulation is a risk assessment showing that children regularly eating chocolate exceed the tolerable Cd intake, assuming that Cd in chocolate is equally bioavailable as in other food items. This study aims to test that ...
Influence of soil properties on the sorption of per- and polyfluoroalkylated substances to soil and the bioavailability and bioaccumulation to terrestrial biota. University of Antwerp
Impact of cellular stress on flavonoid bioavailability and bioactivity assessed by an improved in vitro model of endothelial dysfunction. Ghent University
Flavonoids are secondary plant metabolites that exert many physiological benefits against various
cellular dysfunction mechanisms. Although flavonoids have poor bioavailability, it is known that
they are able to improve endothelial health and thus reduce cardiac events. This conundrum has
been called the “flavonoid paradox”. In the present proposal, the mode of action of flavonoids
towards endothelial dysfunction, will ...
The role of colloids on the bioavailability of phosphate to plants in highly weathered soils. KU Leuven
This Ph.D. addresses a concept that may lead to the development of a new type of phosphate (PO4) fertiliser. That fertiliser is based on nanoparticles of aluminium or iron oxides, coated with PO4. These nanoparticles act as mobile carriers of PO4 in soil, thereby avoiding that PO4-ions are trapped and fixed in soil minerals. Low phosphorus (P) availability is one of the most important plant nutritional problems in strongly weathered soils. ...
Uptake and toxicity of metals from metal mixtures in aquatic and terrestrial systems: rationalization based on metal bioavailability models. KU Leuven
Uptake and toxicity of metals from metal mixtures in aquatic and terrestrial systems: rationalization based on bioavailability Ghent University
Environmental contamination with metals generally occurs as mixtures of different metals. Toxicity of metal mixtures is known to show all potential outcomes, i.e. metals act additive, more than additive or less than additive on organisms. There is a need to understand and quantify these interactions for a better assessment of environmental risks of metals. Here, we will analyze the mixture effects on metal uptake and toxicity by accounting ...

The impact of iron-dissolved organic matter colloids on the fate and bioavailability of trace metals and phosphorus in surface water. KU Leuven
Phosphorus (P) is a limiting nutrient in many aquatic ecosystems. In agriculture, P is present in fertilizer and in animal manure. Widespread and intensive use of fertilizer and animal manure cause diffuse P emissions to the environment, leading to eutrophication of water bodies and impaired water quality. The fate of P in natural waters is strongly linked to that of iron (Fe) bearing particles, to which P can bind. Streams contain ...
