Health effects of nanoparticles – 4
Narrator: This is NIH Health Matters. I’m Joe Balintfy. Microcirculation is the blood flow in the tiniest blood vessels in the body.
Nurkiewicz: And these blood vessels are responsible for the delivery and removal of nutrients and wastes in any given tissue of the body.
Narrator: Dr. Tim Nurkiewicz at West Virginia University studies the health of these vessles, including exposure to nanoparticles, micro-machines 50-thousand times smaller than a human hair.
Nurkiewicz: The question is what is the persistence of these nanoparticles once they are intentionally placed in the body?
Narrator: He adds that ongoing studies will find out how long the affects of these particles affect normal health. For details on this research, visit niehs.nih.gov. Health Matters is produced by the National Institutes of Health, part of the U.S. Department of Health and Human Services.
