Immunochemical methods for environmental analysis must be taken into c
onsideration more for their ability to expand the potential of analyti
cal measures rather than for substituting current methodologies. Moreo
ver, the full potential of these methods has yet to be realized. Indee
d, the terms and concepts of immunology are new to most analytical che
mists, even if environmental science has always been an interdisciplin
ary field. On the other hand, the clinical development of immunoassays
means that much experience has been gained in the analysis of blood,
urine, and tissue samples. The immunochemical analysis of samples from
soils, ground water, waste chemicals, poses new challenges in sample
preparation that have yet to be extensively studied, and in the future
there may be immunoassays better suited for the particular problems a
ssociated with environmental monitoring.
