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...

You'll need brake cleaners for Tesla brakes too. Less of it since you change the brake pads and rotors less often but it'll still be used.

This made me laugh. Well played, sir.

They must have perceived some threats because they created this entire astroturf campaign for the pro-gas side. https://youtu.be/hX2aZUav-54?t=708

No, they didn't perceive threats, they perceived opportunity to push harder on the culture war, since it's basically their leading platform and leading means of generating the outrage that keeps their people voting. The "threat" was entirely manufactured. The group discussing it were not even TALKING about banning or confiscating stoves.

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.

> And we let teenagers do this, with no personal protective equipment and no basic supervision. Gas pumps have mandatory vapor recovery systems for decades now. That problem is long solved.

At least in the US, vapor recovery seems to be implemented differently by state. In California I notice fumes when pumping gas far less than in New York. There seems to be various types of nozzles and legislation (some with rubber boots and some without). Since 2006 cars were apparently required to have vapor recovery systems built in, so the EPA has dropped requirements for systems at the pump. California (not surprisingly) still seems to lead the way in improving the effectiveness of the systems despite the EPA backing off.

perhaps as a society we need to stop dismissing things containing plastics, synthetic fibres, rubber, resins, dyes and pharmaceuticals as otherwise harmless. I personally strongly avoid sleeping on or wearing anything containing synthetic fibres unless absolutely necessary. dyes I'm less cautious about, as short of dressing like a hippy they're almost impossible to avoid.

it would be worse if I was a woman I'm sure, god knows what nonsense cosmetics contain

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.

>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. I've been wondering about this a lot in recent years. Particularly in regards to medications/pharmaceuticals but also environmental containments/traces (which can include pharmaceuticals of course), pair with this what we are jus…

> I really wonder why more health research and workplace safety resources aren't being directed to look at compound and long term exposures.

Probably because no one wants to find the various smoking guns alongside the fears of what each of the ensuing lawsuits would cost. Ignorance is bliss as they say.

I guess you are referring to stage 2 recovery systems on pump handles which are not uniformly required. As per usual, the US is large and regulations are often bare minimums with different states implementing different interpretations or additional requirements.

Here’s the 2012 EPA ruling which loosened the requirement for stage 2 recovery systems: https://www.govinfo.gov/app/details/FR-2012-05-16/2012-11846 which led directly to this move in Arizona: https://agriculture.az.gov/weights-measures/fueling/gasoline...

When I was taking organic chemistry my (mid-to-late 60s at the time in ~20010) teacher told us an anecdote about benzene when we started learning about aromatic molecules. She told us that they used to clean their lab bench with benzene solvent to make it sparkling clean. Of course, she also told us it was carcinogenic and then finished by saying a lot of her contemporary colleagues that went into organic chemistry r…

Chemists used to basically bathe in Benzene back in the day. I’ve heard that they as a group tended to die in their 60’s. Most teaching Chem labs tend to work with small amounts of chemicals today and try to avoid the nasty stuff if possible.

That doesn’t solve the problem of people splashing it on themselves, from faulty handles, which I’ve experienced and seen within the last decade.

My father (and me) washed engine parts with gasoline. And occasionally degreased our hands (followed by dish soap and sugar). We practically bathed in the stuff. Then my father discovered Goop. My father also dumped engine oil into storm drains. Then into the ground when that was banned. Yes, he was an idiot. (Becoming a treehugger was probably an act of rebellion.)

My father used to change the car oil on the lawn rather than the driveway. He would do this less than 100 ft from the well that supplied our drinking water. At some point he stopped but it certainly lasted through multiple vehicles.
