One of the
major human activities affecting the earth is the use of fossil
fuels for transportation. Substantial efforts have, and continue to
be, expended evaluating the influence of associated releases of CO2
on global climate, the roles of fuel-derived hydrocarbons and
oxygenates in the formation of photochemical smog, and the prospects
for environmental damage due to fuel spills above and below ground.
However, almost nothing is known about the environmental fates and
effects of the suite of synthetic additives being added to fuels in
order to tailor the fuel properties to meet the needs of modern
combustion engines and constraints imposed by recent legislation.
This is alarming, especially in light of the historical problems
derived from the addition to gasoline of the antiknock agent,
tetraethyl lead.
Goal/Objective
To identify
problematic additives and to develop a model and approach for
estimating prospective environmental hazards of new additives before
they are utilized widely.
