Preface
Pesticides have played a significant role in increasing food
production, and in view of growing worldwide food demand we can
expect the use of these chemicals to increase. However, some of
them have found their way into the biosphere and have been classi
fied as persistent toxic chemicals. This has resulted in serious
concern about environmental contamination. Since we are going to
continue using chemicals, we should learn more about such aspects
as their transport in the environment, the relationship of their
physical-chemical properties to transport, their persistence in the
biosphere, their partitioning in the biota, and toxicological and
epidemiological forecasting based on physical-chemical properties.
Environmental chemodynamics is the name given to a subject which
deals with some of the above topics, utilizing the principles of
such disciplines as chemistry, physics, systems analysis, modelling,
engineering, and medical and biological sciences.
To ensure the safety of the environment, we must know more
about the chemodynamical behavior of pesticides and related chemi
cals. The purpose of the symposium "Environmental Dynamics of Pes
ticides" was to explore the concept of chemodynamics as applied to
pesticides and thus may help in developing the emerging field of
environmental chemodynamics. The symposium was held during the
l37th National American Chemical Society Meeting at Los Angeles,
California, during April, 1974. The three sessions in the sym
posium were chai'red by Drs. V.H. Freed, D.G. Crosby, and R. Haque.
This volume of the proceedings contains papers on behavior of
chemicals in air, water, soil, and biota and includes such topics
as modelling in the environment; photochemical behavior; adsorption,
leaching, and breakdown; vapor loss; interaction with biological
macromolecules; and detoxication by biota. The contributors are
recognized experts in their fields and represent academia, industry,
and government laboratories. We thank all the contributors for
submitting their manuscripts. Without their interest and coopera
tion, it would have been impossible to complete this book. Each
author should be credited for his own contribution.
We are grateful to the Division of Pesticide Chemistry of the
American Chemical Society, its membership, and its officers for

ENVIRONMENTAL DYNAMICS OF PESTICIDES: AN OVERVIEW

Chemicals for many years have been an important means of con
trolling pests afflicting man, his animals, and food crops. Informed
opinion is a consensus that with the growing world food crisis,
chemicals for pest control will continue to be vital in production
of food. This does not minimize other non-chemical approaches, or
integrated pest control approaches, but rather recognize that pes
ticides remain in many instances our sole weapon of defense.
Beneficial though use of pesticides is, it is not without
attendant problems. One of these problems is that not all of the
chemicals will remain in the area of treatment. The physico-chemical
properties of the substance, together with environmental transport
processes result in a portion of the chemical released moving else
where in the environment. Indeed this has been one of the puzzling
and even troublesome questions of our time. Traces of certain of
the more persistent chemicals have been found well removed from areas
of treatment, that is quite common to find water bodies near to, but
not necessarily adjacent to treated areas contaminated with the
material. Instances of long distance; i.e., several hundred miles,
aerial transport have been reported.
The finding that pesticides were being transported from areas
of treatment confronts us with a number of challenging scientific
questions; among them:
1. What mechanisms are involved in this transport process,
and how may they be accurately described and quantitated.
2 V. H. FREED AND R. HAQUE
2. What amount or proportion of the material that has been
used is thus transported.
3. What is the fate and behavior of the material during the
transport process and upon arrival at the ultimate destination.
4. What, if any, are the biological consequences.
5. How to ensure that the analytical methods accurately iden
tify and measure the low level residues.
Biologists and chemists for many years have studied fate and
behavior of chemicals, but usually within a limited sphere and in
only one component of the environment. More recently, scientists
have essayed a broader more comprehensive study of these problems.
These efforts have evolved into a systematic, interdisciplinary
area of study that has come to be labeled chemodynamics. Concern
in this symposia with environmental dynamics of pesticides is il
lustrative of the interest and approaches being used today. The
field has three basic areas of concern; namely,
1. An understanding of and model of the environment and the
various interactions.
2. A detailed knowledge of the chemical structure and proper
ties of pesticides.
3. Interaction of the chemical and its properties with ele
ments of the environment as related to behavior, transport, and fate
of the chemical.
Recognizing that there are four components of the environment;
namely, atmosphere, lithosphere (soil), hydrosphere (water), and
biosphere (living organisms), that specific parameters measure the
properties of each component and that there is a dynamic equilibrium
among them, permits a modeling of the transport processes and the
distribution of the chemicals in the four components. Such distri
bution can be described with appropriate mathematical equations.
This symposium will concern itself with the behavior of pesti
cides in air, water, soil, and the biota. Rather specific attention
will be given to the transport processes, physico-chemical properties
of the compounds such as vapor pressures, solubilities, etc., that
influence behavior and the mechanisms of partitioning of the pesti
cide into a particular component of the environment. Additionally,
attention will be given to the fate of the chemicals as influenced
by photochemical reaction, microbiological attack, and other types
of reactions. What the symposium is attempting to do is rather new;
namely, a systematic holistic approach to the dynamics of pesticides.
