Linking nanomaterial-induced mitochondrial dysfunction to existing adverse outcome pathways for chemicals.
(AOP) framework plays a crucial role in the paradigm shift of toxicity testing towards the development and use of new approach methodologies. AOP s developed for chemicals are in theory applicable to ...
Regulatory safety assessment of nanoparticles for the food chain in Europe
Keywords: Integrated approaches to testing and assessment (IATA) nanomaterial particulate material Physicochemical characterisation Risk Assessment Toxicity testing Abstract: Background The risk assessment of ...
Multidimensional Fingerprint Development for the Detection of Tribulus terrestris in Plant Food Supplements
properties. According to the Belgian Royal Decree of 1997, Tribulus is a regulated plant when used in plant food supplements. The dangers of self-medication and toxicity of such plant supplements is heightened ...
Safety assessment of titanium dioxide (E171) as a food additive.
Studies on general and organ toxicity did not indicate adverse effects with either E 171 up to a dose of 1,000 mg/kg body weight (bw) per day or with TiO NP s (> 30 nm) up to the highest dose tested of ...
Safety assessment of titanium dioxide (E171) as a food additive
dose tested of 100 mg/kg bw per day. No effects on reproductive and developmental toxicity were observed up to a dose of 1,000 mg E 171/kg bw per day, the highest dose tested in the EOGRT study. However, ...
Identifying nanodescriptors to predict the toxicity of nanomaterials: a case study on titanium dioxide
8, Issue 2 (2021) Abstract: Since the evaluation of nanomaterial (NM) hazards by animal testing is expensive, time-consuming and critical from an ethical point of view, much interest is being given to ...
Ecotoxicity profile of heavily contaminated surface water of two rivers in Tunisia
areas. Combining chemical and biological approaches, allowed the detection of water ecotoxicity in testing organisms and the identification of possible contributors to the toxicity observed in these ...
Chemical and toxciological characterization of e-liquid cigarettes
(diacetyl and acetylpropionyl) which are toxic when inhaled are also present. In order to analyse the composition of the e-cigarettes and to check the e-liquids for the abovementioned issues, alternative ...
Agglomeration of titanium dioxide nanoparticles increases toxicological responses in vitro and in vivo
influence of NP agglomeration on their toxicity/biological responses in vitro and in vivo. Results: We tested two TiO2 NP s with different primary sizes (17 and 117 nm) and prepared ad-hoc suspensions ...
Bepaling van spoorelementen in diverse matrices met spectrometische technieken.
functioning of the body, and de non-essential trace elements that have no purpose in organism and due to accumulation in the tissues, cause toxicity. Purpose Analyze concentration of trace elements in various ...
