A lot of chemicals seem to have effects on the endocrine system. I wonder if there is potentially an issue with them in aggregate. Such that the dose of any single chemical isn't problematic but all of them together with similar effects causes a problem.

That would require some interaction between the chemicals, that potentiates their effect. Or they act through common pathways. But if the threshold effect is 1 microgram, and you're exposed to 1 picogram of 10 different chemicals all working through the same pathway, you're still below the threshold effect.

I think the idea was more if the threshold effect is 1 microgram and you're exposed to 100 picograms of 10 different chemicals.

Benzene is everywhere, particularly in trace amounts in otherwise harmless products. Benzene is a building block for the production of many chemicals, including plastics, synthetic fibers, rubber, resins, dyes and pharmaceuticals, and residual amounts may remain in the final products. Benzene is used as a solvent and cleaning agent in printing, paint manufacturing, electronics, etc. Benzene contributes to the overall…

Things i wish i knew before buying a fixer upper car is all the chemicals involved. Just one sniff of the brake cleaner and the rest of the day is gone. Probably some IQ ponis down the drain too. Should've just bought a tesla and be done with it...

Back in the late 80s/early 90s my elderly Italian-speaking grandfather lived with us in the states. Whenever he'd watch driving my gas RC car, if the thing would die he'd motion with his thumb down (like a pouring spout) while saying "benzene?". I don't know if it's an Italian language thing, his dialect, or just his knowledge of engines, but RC car fuel was "benzene". Makes me wonder what kind of benzene exposure he…

That’s the word for “gasoline” in Italian and a number of other languages. https://en.m.wikipedia.org/wiki/Gasoline#/languages

I and family was expose to very large amounts of benzene from a gas leak over the course of three months. It was a rental house came with that smell, and they kept making excuses as to why it had a weird smell.

It’s taken about five years to get something resembling normal health.

Intelligence of all family members dropped like crazy. Blood started clotting a lot. Nerve pain and inflammation were the norm.

Doctors didn’t know what effect those chemicals would have so refused to sign any paperwork saying it was cause of all health problems. So lawyers wouldn’t take the case.

Only in the past year can me and my oldest daughter start having normal conversations like we used to.

Brake cleaner is the worst, the others are pretty much okay as long as you avoid exposure. ATF, Oil, etc - just wear proper PPE :)

Crazy how people just drive around in cars and fuel up with gasoline that contains like 2% benzene. And we let teenagers do this, with no personal protective equipment and no basic supervision.

Can also say the same thing how teens can drive moving things that can blow up, crash, cause loss of limb and life... and untold amounts in property damage.

Is that only for urban areas? I dimly recall old style nozzles still in use while driving cross country.

Good god, it seems like y'all dropped the requirement for Stage 2 vapor recovery systems in 2011 [1] based on the pretense of onboard filters in vehicles being enough... meanwhile here in the EU, where many member countries already had national requirements for years prior to that, we passed that requirement in 2009 [2].

The US attitude, particular to expensive systems, on anything emissions related continues to negatively amaze me.

To nitpick, at least in the EU regulations limit the benzene content in gasoline to a maximum of 1%. I had a vague recollection the limit was actually slightly stricter in the USA at 0.6%, but maybe my memory fails me.
