Growing rates of pollution not only have an effect on our
planet, but on human health without even being aware of it. A recent study from
Lancaster University has found large traces of toxic nanoparticles in human
brains. This study took place in both the U.K. and Mexico using 37 people ages
between 3 and 92 years old. The specific particle found was Magnetite.
Magnetite is a type of iron oxide that derives from large quantities of
combustion from industrial processing or everyday car exhaust. Spectroscopic
analysis was used to identify these particles as Magnetite. Recent studies have
shown that exposure to these pollutants can increase an individuals risk to Alzheimer’s
disease. Very small amounts of Magnetite are usually found in the brain “biological variety is small and crystal shaped. The particles associated with
air pollution are suspected to be harmful large and spherical, formed as
molten droplets..” (Rodriguez, 2016). Other metals such as cobalt and platinum
(that come from car exhaust as well) have also been found. Scientists believe
the reason these particles are able to build up in human brains is due to the
way the body processes inhaled particles, thus going directly to the brain.
