AMA #67: Microplastics, PFAS, and phthalates: understanding health risks and a framework for minimizing exposure and mitigating risk

There's a figure we've got that shows the number of scientific publications focusing on microplastics in the last 20 years... It still looks like you're basically watching Bitcoin from 2010 to 2020. That's effectively what's been going on. So I don't doubt that there are more and more microplastics accumulating in the environment—that's likely—but we can't lose sight of the fact that we're also looking for it nonstop.

The most common route of human exposure [of microplastics] is from inhaling, plastic, dust, and fibers and from consuming food and beverages that contain these micro- and nanoplastics.

There doesn't appear to be any restriction in the use of phthalates for personal care products. I think this is probably where people are going to see their greatest exposure to them.

The majority to the tune of 99% of ingested microplastics are going to be eliminated through stool.
