Magnesium
is a component of milk of magnesia, often used medicinally to treat acid in the
digestive system. Sodium chloride is often used in pools as a buffer. Both of
these are present in Ottawa’s deicing salt and sand and could act as a buffer for
the acidity in the snow. Especially since deicing salts and sands are used more
often in high traffic areas. This could explain the why pH of the snow of
Ottawa’s downtown is far more basic than that of the Greenbelt.

Even though our data did
not end up supporting our hypothesis is it is still important to reduce the use
of cars or at least the quantity in which they pollute. Just because our data didn’t
point to the direct link between automobile use and acid snow does not mean
there isn’t one. Therefore it is important to reduce our automobile use. Public
transportation is a good way to reduce the amount in which we use cars. Also
choosing green transportation like bicycles and even walking can reduce
pollution. Scientists are finding alternatives for fuel. The use of alternative
fuels, such as biodiesel and ethanol, for light duty CI engines to approach the
target of ultra low NOx and PM emissions is currently being studied. Recently
the interest in the butanol as a viable alternative either single or blended
with conventional based fuels both to cut the demand for fossil fuel and to
reduce emissions of particulate matter without significantly increasing in NOx is
growing. Also municipalities can reduce car emissions through urban
planning techniques such as traffic calming initiatives, pedestrian walkways, decreasing
parking availabilities, improving public transportation and even increasing
taxes based on number of cars owned by an individual.
