For those wondering what the chemical is and its purpose:
>6PPD helps by reacting with ozone before it can react with the tire rubber, sparing the tires.
>But when 6PPD reacts with ozone, the researchers found that it was transformed into multiple chemicals, including 6PPD-quinone (pronounced “kwih-known”), the toxic chemical that is responsible for killing the salmon.
> 6PPD helps by reacting with ozone before it can react with the tire rubber, sparing the tires.
BTW, these kinds of molecules are known as "anti-oxidants". Use that knowledge to blow up the brains of people who think that "anti-oxidant" is some natural healing magic.
If you could finally stop humans oxidising, you could keep all that carbon in them nice and sequestered, and massively curtail lifetime carbon-intensive emissions. Another great win for antioxidants: nature's miracle cure for humanity!
