Synergism
"Synergism is the interaction of two or more agents so that
their combined effect is greater than the sum of their individual
effects." For example, usual concentrations of sulphur dioxide
alone would
not produce respiratory problems, but in conjunction with suspended
particles contributes to bronchitis and emphysema. The insecticide
DDT
is found in the ocean in small concentrations. DDT is not soluble
in
water, but is extremely soluble in oil. As a result of an oil
spill,
marine life is exposed to a much more harmful concentration of DDT
than
usual. Therefore, the effects of an oil spill are enhanced or
synergistic.
Synergism
comes from the Greek sunergos meaning working together.
The cooperative interaction of two ideas, objects, or organisms has
relevance in many fields. In business, cooperation of subsidiaries and
parts of a corporation result in an ehanced combined effect. In theology,
it is the combination of divine grace and human will through which
individual salvation is achieved. In physiology, it is the cooperation
between muscles that produce coordinated movement.
