    Health effects of aerosol particles

    Atmospheric particles of both natural and anthropogenic origin have been known to affect public health of the exposed population at large. We are collaborating with epidemiologists, statisticians, pneumologists and toxicologists in order to establish a causla relationship between the properties of particles and negative health outcomes owing to the exposure of the public to these particles.

    Our working hypothesis is that the gas-condensed phase interface (the ''surface'' of the particle) is the gateway of the particle-substrate interaction such as deposition of a particle onto a biological membrane or to a solid support. We have developed a gas phase interrogation technique which enables the quantification of the surface functional groups that act like reactive ''hooks'' that latch onto membranes or solid supports. This is the first step required for the particle to cross cell boundaries and be internalized into different compartments of the human body (cardiovascular system, central nervous system, blood-brain barrier, etc.). Depending on the origin of particles the abundance of acidic, partially oxidized, oxidizable and basic surface functionalities determines their potential reactivity and deleterious effect through initial adsorption. Together with the investigation of the volume of the particle which reveals its origin using thermal evaporation of the particle in an aerosol mass spectrometer we obtain both the origin and toxicity of particles in order to create a fingerprint of atmospheric particulate. This information may form the basis for a ''particle alarm'' system that may operate on a future national level.
