a Problem in Toxicology
The tools of modern analytical chemistry are widely
applied in environmental investigations. In this feature, we
describe a case study in which quantitative analysis was
used to determine the agent that caused deaths in a population
of white-tailed deer inhabiting a wildlife preserve
of a national recreational area in Kentucky. We begin with
a description of the problem and then show how the steps
illustrated in Figure 1-2 were used to solve the analytical
problem. This case study also shows how chemical analysis
is used in a broad context as an integral part of a feedback
control system, as depicted in Figure 1-3.
