Heavy

mercury,
lead,

cadmium, etc.

Coal
fired power plants,

|
mercury
is present in the
|
ash
and is reduced to
|
|
mercury vapor
|
|
|
|
 |
 |
Environmental
poison, health hazards to humans, difficult to
|
|
capture because
concentrations are very low. Future
|
|
regulations
will impose far more stringent standards.

Fine

particulates,

sulfates,

aromatics,
etc.

Coal
fired power plants,

also to a lesser extent,

cars, (diesel),
and

conventional

Apparent
health hazard, statistical data
point to strong
|
|
correlations
between fine particulate emissions from coal
|
|
|
fired
power plants and mortality rates.
Particles smaller
|
|
than
10 micron are unregulated, are a category of particular
|
|
|
concern
as they tend to make it into the lung where they get
|
captured. Regulations are still being discussed.
|
|
Visual
pollution from power plant haze (e.g. Grand
|
|
|
Canyon).

plants, cars, machinery

 |
Climate
change and environmental change, global impact,
|
|
|
direct human
impact is considered minimal.
|
|
Carbon
dioxide is the normal end result of power generation
|
|
from
fossil fuels, it is therefore difficult to avoid it.
