Mordants (color fixatives), dyes, sizing and bleach in textiles can be mutagenic, carcinogenic and generally toxic. Under normal circumstances they don't get into our system, but here's a recent article that is highly disturbing. I posted the link in the other thread I'm focused on, but long story short this shows how these toxic textile particles can get into the oceans and then what the article doesn't say bluntly is that is must already be in our human food chain (now, not eventually). Not to mention direct exposure to BPA for another unwanted source of plastics in our bodies.
So Browne and his team recruited far-flung colleagues on six continents to scoop sand from 18 beaches. (The scientists had to wear all natural-fiber clothing, lest their own garments shed lint into the samples.) Back in the lab, the researchers painstakingly separated the plastic from the sand—a process that involved, among other things, hand plucking microscopic fibers from filter papers. A chemical analysis showed that nearly 80% of those filaments were made of polyester or acrylic, compounds common in textiles.
Not a single beach was free of the colorful synthetic lint. Each cup (250 milliliters) of sand contained at least two fibers and as many as 31. The most contaminated samples came from areas with the highest human population density, suggesting that cities were an important source of the lint.

Browne's own work has shown that filter-feeding mussels will consume tiny plastic particles, which then enter the animals' bloodstreams and even their cells. If the same thing happens in nature, the plastic fibers could "end up on our dinner plates," incorporated into seafood, Browne warns
