What I am trying to say that when unleaded fuels entered the
market they
were toxic. You wouldn't want to inhale the vapours or get any
splashed
on your hands.

More so than regular 4-star ?

I often use petrol for cleaning oily car components. And don't
bother with
gloves. My hands didn't fall off after unleaded disappeared.

But there is some cancer risk due to the higher level
of benzenes, and don’t you have prostate cancer ?

Benzene is bioaccumulative. It collects in bone marrow.

That means every time you choose to expose yourself to it,
you're adding to the total amount stored in your bone marrow.

Most evidence suggests it isn't bioaccumulative, first hit:

Can you provide evidence to assist with your claim?

Well, it's not in the list here. Just some chlorinated
benzene products.

And the stuff looks pretty safe here. There was other
materials we used in the chem building that were as
dangerous as the entries here suggest. I don't know
if this info was all available, the year the benzene was
removed.

Exposure to 150 to 650 ppm for 4
months to 15 years caused pancytopenia (Aksoy
et al., 1972; Aksoy & Erdem, 1978). Chronic
exposure of up to eight years at a mean
benzene concentration of 75 ppm was
associated with the development of anemia and
leukopenia, but no such association was found
at mean exposure concentrations of 15 to 20
ppm for up to 27 years (Kipen et al., 1989).

This was the story I was given at the time, when
every bottle of benzene was remove from the chem building.

Looks like it's safer than dry cleaning fluid
(living in a dry cleaning plant).

A good time for all, and party on!

My mistake.
