Banned-in-the-70s flame retardants still showing up across Europe, kinda grim

This study found PBDEs, chemicals phased out decades ago, still showing up in ecosystems across 25 European countries. The researchers seemed genuinely surprised the levels were this persistent, which kinda tracks with how stubborn these fat-soluble compounds are.
It hits close to home for anyone running peptides or supplements, because environmental contaminants are exactly the kind of thing that can quietly skew your bloodwork. If your liver enzymes or lipid panel look off and you can't explain it, stuff like this is a reminder that your baseline exposure might matter more than the compound itself.
Has anyone here factored legacy POPs into how they interpret their own labs? Curious how others think about this stuff when they're trying to optimize. 🥗

- grinder265: Ngl this one got me thinking. I run a standard lipid and liver panel every 3-4 months and never once considered PBDE load as a variable, even though the bioaccumulation story makes sense from a PK standpoint. A couple questions for anyone who's looked into this. Has anyone actually tested their own body burden, like through a private heavy metals or environmental toxin panel, and gotten back results that were meaningfully high? And if so, did you change anything about your stack or protocol bas
- quiet_ironman: I actually did a private toxin screen last year after seeing weird ALT spikes. My PBDE came back in the 90th percentile for my area. I didn’t tweak my peptide stack but I added more cruciferous veggies and sweated more in sauna. Just my own experience.
- tiredmira: That's really interesting about the PBDE percentile, 90th is high. Were the ALT spikes what pushed you to do the screen, or were you already curious because of stuff you'd been reading? I'm asking because my own liver enzymes have been creeping up and my doctor basically shrugged it off. I've been wondering if there's a point in paying for a private toxin panel out of pocket or if it's mostly peace of mind. Also curious how long you gave the sauna + cruciferous approach before you saw anything
- tiredmira: I haven't tested my own burden directly, tbh it wasn't on my radar until I started digging into POPs data for work adjacent reasons. The PK angle you mentioned is basically what made me go "oh, that's why my trend lines don't always line up cleanly." I think most people probably skip it because the panels are pricey and the interventions are kinda unsatisfying, like "move somewhere less industrialized and eat less farmed fish." 😅
