Potential toxic effects associated to metals and endotoxin present in PM10: an ancillary study using multivariate analysis.

abstract：:Continuous environmental or occupational exposure to airborne particulate pollution is believed to be a major hazard for human health. A technique to characterize their deposition and clearance from the lungs is fundamental to understand the underlying mechanisms behind their negative health effects. In this work, we ...
