could have come from tire pollution. By the
way, your car's cabin is a hotspot for
microplastics as well.
A further report published in Environmental
Research found an incredible 2,456 chemical
compounds when tire rubber was investigated.
One of the most dangerous was a hydrocarbon
called 6PPD; when it's released into the
atmosphere by tires, it can combine with the
ozone in the air, causing a chemical reaction
that creates 6PPD-quinone - which has proven
deadly to salmon and is now being connected
to neurological issues in humans. PAHS
(Polycyclic Aromatic Hydrocarbons) are among
the other nasty ingredients in tires, and those
pose a "significant danger to human health and
the well-being of humans," as reported in
Chemosphere. Oh, and the largest non-rubber
material in tires is carbon black, or soot, which
is classified as fine particulate matter - and
that, in turn, is associated with four million
deaths per year.
