calculated pollutant loads from
identified sources. It should be noted
data
however, that because of inadequate
the loads for some important categories
of pollutants were not calculated for the
sources shown and are therefore not included
in this figure. Due to the varying toxicity
of different pollutants, bar heights do not
reflect either the toxicity of the pollutants
or their impacts on beneficial uses.
