Many of the available studies on pesticides are funded and designed by the
companies that produce the chemicals.
Companies that do a large number of
studies may set aside the results of
some studies, but widely distribute the
results of others.
The pesticide industry is more
inclined to fund researchers who produce results that are useful to them
than those who raise the awareness of
potential problems. Those who work
on ways to reduce pesticide use or on
the benefits of alternative agricultural
approaches may find it harder to find
funding and may even be in trouble from
governmental agencies.

Worse still, some researchers working on the environmental impact of
pesticides may face attacks by industry on their scientific credibility, ethics and even their personal lives. For
example, Tyrone Hayes, a biologist at
the University of California, Berkeley,
experienced numerous setbacks. His
work on the herbicide atrazine was
challenged by Syngenta, the large agribusiness that makes the chemical and
attempted to discredit him and invalidate his published work.

CHANGING DANGERS
Pesticides are designed to be toxic
and used to eliminate pests. Herbicides
target weeds, insecticides control
insects and rodenticides target harmful rodents.
Unfortunately, given their inherent toxicity, they are never fully
selective  - all pesticides have the
potential to harm plants, fish, insects
and birds. Some  affect predators,
such as marine mammals, eagles and

polar bears, and many are persistent
organic pollutants.
The challenge for regulators is to figure out how much of the chemical will
have a significant deleterious impact
on significant individuals or organisms.
The scientist can determine the number
of species that will be affected and to
what extent, but the level of acceptable
impact is often a societal decision.

UNCERTAINTIES IN
RISK ESTIMATES
When a manufacturer markets a new
pesticide, it must produce several risk
assessment studies. Toxicological studies need to address a pesticide's effects
on humans; ecotoxicological research
shows its interactions with the environment. These studies determine maximum doses and threshold criteria to
preserve environmental quality in drinking water, soils or aquatic life.
This exercise determines the highest possible concentrations that can
be allowed without adverse effects on
