Nanomaterials have been widely used in a wide range of manufactured products in order to improve/add new properties. Photocatalytic cement maintains clean and white wall fronts and also provides interesting air pollution-reducing properties due to the photocatalytic activity of incorporated TiO2-NMs.

Iron Oxide Nanoparticles (IONPs) are used in several fields of application, mainly in the biomedical field for their magnetic properties and in food additive known as “E172” for their colour. In the present investigation, we focused on IONP effects on Wistar rat following acute oral exposure.

Given toxic nature of many VOCs present within indoor environments, it is necessary to measure and quantify indoor VOC emissions to better inform and protect the public from possible adverse health effects of indoor air pollution. To better understand and quantify this problem, a horizontal flow tube reactor was used to study VOC emissions from selected paint.

Environmental risk assessment of nanomaterials generally relies on a decision-tree based strategy which provides guidance and protocols for the determination of a collection of hazard end-points. Mesocosm testing is based on a different approach. It consists in monitoring the evolution of a re-created miniature ecosystem subsequent to a nanomaterial contamination.

Environmental contamination with TiO2 and the use of TiO2 as a food additive (E171) or in cosmetics result in human exposure to TiO2 via inhalation, ingestion, and through skin contact. When inhaled, most TiO2 particles are cleared via the mucociliary escalator and are then swallowed.

L’objectif de ce colloque est de permettre à des professionnels de différents horizons d’échanger objectivement sur ce sujet. Un focus sera fait sur certains produits, notamment les composts de boues, les biochars, les struvites et autres produits minéraux issus de biomasses, les frass, les digestats et les substances humiques.
