California wants to ban the toxic chemical that gives chrome its classic shine

For decades, hexavalent chromium has provided the silvery showroom finish to countless consumer products, from automobile bumpers and grilles to kitchen faucets and light fixtures. It has also served as an indispensable rust-resistant coating for aviation components, such as airplane landing gear.

But while hardened chrome is harmless, the airborne emissions from the plating process are more than 500 times more toxic than diesel exhaust, and pose a substantial cancer risk to surrounding communities.

In light of these risks, the California Air Resources Board has proposed a landmark ban on the use of so-called chrome-6 in decorative plating by 2027, saying the health hazards of the plating process are borne disproportionately by low-income communities. The rule would also prohibit the chemical’s use for industrial durability — such as providing anti-corrosive coatings — by 2039.

The proposal has drawn praise from clean air advocates but has also sent shock waves through the state’s auto restoration and customization industries. It could also force California aerospace companies and defense contractors to accelerate research into less toxic alternatives.

Or just move out of state...

I remember using potassium dichromate solutions in high school chemistry back in the late 70s.  We played around with benzene, too.  There is no way they would let students do that today.

btw, you can still chrome metals using trivalent chromium.   Much safer.
