Finally, none of the six methods reviewed here
takes into account the environmental impact of pesticides
other than that occurring as a result of field
application. Production, transportation and disposal
of packaging material of pesticides undoubtedly have
impacts on the environment. Methods such as life
cycle assessment (LCA) have been developed to
quantify all environmental impacts of a product during
its entire life cycle (Guin~e et al., 1993). However,
data required to calculate the environmental
impact of pesticides other than that resulting from
field application may be difficult to gather or unavailable.
