Behavior of TiO₂ nanoparticles during incineration of solid paint waste: a lab-scale test.

In order to assess the potential impacts posed by products containing engineered nanoparticles, it is essential to generate more data about the release of these particles from products' life cycle. Although first studies were performed to investigate the release of nanoparticles from use phase, very few data are available on the potential release from recycling or disposal of nano-enhanced products. In this work, we investigated the behavior of TiO2 nanoparticles from incineration of solid paint waste containing these particles.

Behavior of TiO(2) released from Nano-TiO(2)-containing paint and comparison to pristine Nano-TiO(2).

In the assessment of the fate and effects of engineered nanomaterials (ENM), the current focus is on studying the pristine, unaltered materials. However, ENM are incorporated into products and are released over the whole product life cycle, though mainly during the use and disposal phases. So far, released ENMs have only been characterized to a limited extent and almost nothing is known about the behavior of these materials under natural conditions.

Characterization of materials released into water from paint containing nano-SiO2.

In order to assess the possible risks of applications containing engineered nanomaterials, it is essential to generate more data about their release and exposure, so far largely overlooked areas of research. The aim of this work was to study the characterization of the materials released from paint containing nano-SiO2 during weathering and exposure to water. Panels coated with nano-SiO2 containing paint and a nano-free reference paint were exposed to accelerated weathering cycles in a climate chamber.

Formulation effects on the release of silica dioxide nanoparticles from paint debris to water.

Waterborne paints with integrated nanoparticles have been recently introduced into the market as nanoparticles offer improved or novel functionalities to paints. However, the release of nanoparticles during the life cycle of nano-enhanced paint has only been studied to a very limited extent. The paint composition could determine in what quantities and forms the nanoparticles are released.

Release of TiO2 from paints containing pigment-TiO2 or nano-TiO2 by weathering.

The release of nanomaterials from products and applications that are used by industry and consumers has only been studied to a very limited extent. The amount and the characteristics of the released particles determine the potential environmental exposure. In this work we investigated the release of Ti from paints containing pigment-TiO2 and nano-TiO2.

Is nanotechnology revolutionizing the paint and lacquer industry? A critical opinion.

Many paints for indoor and outdoor applications contain biocides and additives for protection against microbial, physical and chemical deterioration. The biocides should remain active as long as they are incorporated in the paint. Protection against microbial colonization should last at least a decade.

Contamination of nanoparticles by endotoxin: evaluation of different test methods.

Background: Nanomaterials can be contaminated with endotoxin (lipopolysaccharides, LPS) during production or handling. In this study, we searched for a convenient in vitro method to evaluate endotoxin contamination in nanoparticle samples. We assessed the reliability of the commonly used limulus amebocyte lysate (LAL) assay and an alternative method based on toll-like receptor (TLR) 4 reporter cells when applied with particles (TiO(2), Ag, CaCO(3) and SiO(2)), or after extraction of the endotoxin as described in the ISO norm 29701.

Engineered nanomaterial risk. Lessons learnt from completed nanotoxicology studies: potential solutions to current and future challenges.

PARTICLE_RISK was one of the first multidisciplinary projects funded by the European Commission's Framework Programme that was responsible for evaluating the implications of nanomaterial (NM) exposure on human health. This project was the basis for this review which identifies the challenges that exist within the assessment of NM risk. We have retrospectively reflected on the findings of completed nanotoxicology studies to consider what progress and advances have been made within the risk assessment of NMs, as well as discussing the direction that nanotoxicology research is taking and identifying the limitations and failings of existing research.

Weight of evidence approach for the relative hazard ranking of nanomaterials.

In assessing hazard for human health posed by newly engineered nanomaterials (ENM), approaches such as Weight of Evidence (WOE) and expert judgment are required to develop conclusions about the hazard of ENM. This is because all factors affecting hazard are not currently well defined and are often subject to different interpretation. Here we report the application of a WOE procedure to assess the potential of ENM to cause harm for human health, by integrating and combining physicochemical properties of NM and toxicity data obtained within the EU-funded Particle Risk project.
