Human excretion of bisphenol A

Microplastics are a ubiquitous contaminant in modern life. This study show you can sweat some of it out of your body.

Human Excretion of Bisphenol A: Blood, Urine, and Sweat (BUS) Study (2012)

Abstract

Background. Bisphenol A (BPA) is an ubiquitous chemical contaminant that has recently been associated with adverse effects on human health. There is incomplete understanding of BPA toxicokinetics, and there are no established interventions to eliminate this compound from the human body. Using 20 study participants, this study was designed to assess the relative concentration of BPA in three body fluids—blood, urine, and sweat—and to determine whether induced sweating may be a therapeutic intervention with potential to facilitate elimination of this compound. Methods. Blood, urine, and sweat were collected from 20 individuals (10 healthy participants and 10 participants with assorted health problems) and analyzed for various environmental toxicants including BPA. Results. BPA was found to differing degrees in each of blood, urine, and sweat. In 16 of 20 participants, BPA was identified in sweat, even in some individuals with no BPA detected in their serum or urine samples. Conclusions. Biomonitoring of BPA through blood and/or urine testing may underestimate the total body burden of this potential toxicant. Sweat analysis should be considered as an additional method for monitoring bioaccumulation of BPA in humans. Induced sweating appears to be a potential method for elimination of BPA.

Got Sauna?

I like this bar graph. USA is not number 1.

Interesting. Thanks for sharing.
However, the study isn't precise enough (I didn't read the whole study, only the excerpt). BPA molecules has different sizes. Which size is allowed to migrate through the skin should have been put forwards. => Need to go deeper in the experiment.
Edit: you've posted a second post in-between.
=> NPS is clearly the one that causes a "problem" Still should be investigated further.

"BPA has a short half-life of around 6 hours"

I worry more about the dioxins and pcb type chemicals. They have a half life of years and their harder to avoid them everything else.

@LucH - Yes, I agree more research is needed.

For me, this suggests that a sauna deserves some consideration. It boils down to a benefit-versus-burden analysis. I do not think that sitting in a sauna is very burdensome. As to the benefit of using a sauna,

The constant exposure every day(?) and multiple times each day (?) make its short half-life less relevant.

Taurine, EGCG and/or curcumin have been found to be useful in rodents.

@Insomniac - Your right. But do not lose any more sleep over it.

Among the Scandinavian countries, Finland is lowest. Don't they use the sauna a lot?

@Insomniac “forever” chemicals is probably a fear based trauma mind control psyop by freemasons

Yes they do. In a different thread I noted that despite of their saunas, they do not live any longer than their neighbors. see
After diet, exercise and sleep, using a sauna may be of the best things for health

The bar graph is from an observational study. So the data is inherently unreliable. My eye noticed that Norway has bisphenol A more than 2X of every other country. Why? Bettter data collecting?

@LucH - France appears to have relatively low levels of exposure.

Thanks.
I speak French but from Belgium (Liège). No matter, except for Phas: Last month, there's been some noisy agitation from TV (RTBF) saying a lot of "Commnunes" (local districts) in South Belgium have rivers / sources contaminated by PHAS from industrial discharges. I'm not concerned but ...

Last week it was a reportage from France 2 TV, saying some sources from Nestlé Waters have been manipulated / filtered.
Plusieurs producteurs d’eau en bouteille ont filtré illégalement leur eau pour masquer une contamination.
Selon une enquête du "Monde" et de la cellule investigation de Radio France, Nestlé et d’autres industriels ont caché au public que l’eau qu’ils pompaient était contaminée. Pour continuer de la mettre en bouteille, ils ont eu recours à des systèmes de purification interdits. 30% des marques seraient concernées.

What many people don't know is why inhale far more micro plastics than we ingest. The size of a credit card every week.
Frequently airing a room is important to let less poluted new air come in.
