Thousands of new particles in workplaces despite large knowledge gap
Date:12/3/2013

etween exposure to NPs and asthmatic symptoms in some animals. Does the human body undergo similar inflammation upon contact with NPs? In the absence of any standards for workers, it's best to take a closer look, insists Girard. "At this time, nanoparticles have not been properly identified and are often handled without protection. If they enter the body through the skin, respiratory tract, or even ingestion, we have no idea what happens next." In his lab, a variety of approaches will help further understanding of how nanoparticles of different types and sizes interact. Cellular processes will be examined in detail.

At the rate at which NPs are being developed, Girard could be conducting systematic nanotoxicology studies for many years to come. "I will of course need the support of a strong team," said Girard. "I already have one I am very proud of, and it will be expanded for the new project." The IRSST grant will be used to hire staff and student researchers.

The work seems daunting, but Girard is up to the challenge. He is convinced others will follow suit and that the medium-term results will help establish informed standards to regulate the use of nanoparticles and protect the health of workers and the public.
