Negative Effects of Nitrogen Dioxide May be due to Testosterone


Copyright 2004, James Michael Howard, Fayetteville, Arkansas, U.S.A.


Nitrogen dioxide is a “pollutant” that is created by burning fuels.
The main sources are power plants and motor vehicles.  It is known to
cause problems for people including increased susceptibility to
respiratory infections, snoring, lung problems, etc.  I suggest
nitrogen dioxide may cause its problems because nitrogen dioxide may
increase testosterone in humans as it does in rats (below).  Increased
testosterone may be involved in a number of diseases.


In rats, nitrogen dioxide increases testosterone (Environ Health
Perspect 2001; 109: 111-9 and ibid 1999; 107: 539-44).
