The world's aging populations, with age-related disorders affecting
every organ system, are generating medical care costs rising at an
unsustainable rate. Although such disorders are expected, we are
now beginning to ask whether exposures to toxic environmental
chemicals hasten or account for their onset. This book provides a
detailed review of current knowledge about the possible
associations between a variety of chemical contaminants and adverse
effects later in life. It will serve as a guide to policy decisions
about protecting us from chemical exposures that distort the aging
process. It provides a guide to current understanding of how our
contaminated environment may be influencing the aging process and
contains examples of approaches that will help us undertake further
research on this topic. It will help alert policy makers to the
implications of chemical pollution for aging populations and will
help formulate initiatives for environmental protection. The book
provides a comprehensive view of how environmental exposures may
alter the health of our aging population. For readers engaged in
environmental research, or aging research, it will highlight a
number of questions that need more attention For other readers,
they will learn something about the kind of exposures they should
avoid or that they should prompt policy makers to reduce or
eliminate.
Neurotoxicity and Developmental Disabilities is a comprehensive
review of the relationship between neurotoxicity and mental
retardation. Though individual chapters each focus on a specific
toxin, the chapters jointly emphasize that many variables influence
the developmental outcomes following exposure to neurotoxicants,
including timing of exposure, pattern of exposure, dose,
susceptibility, and environmental conditions.
Coverage includes the developmental consequences of maternal
exposure to methyl mercury, and direct exposure to PCBs and
Dioxins, lead, methanol, parental smoking, pthalates and
pesticides. Additional chapters review research on environmental
agents and autism, and assessment studies of exposure.
This thematic volume in the "International Review of Research in
Mental Retardation" begins with forewords by Stephen R. Schroeder,
and series editor Laraine Glidden.
Behavioral toxicology is a young discipline in the United States;
so young, in fact, that this is one of its first books. Behavioral
questions are bound to play a major role in future scientific work
and governmental decisions involving the health effects of
environmental contaminants and other chemicals. This role springs
from two key problems that face scientists and public agencies
required to set acceptable exposure standards or to determine
criteria for the toxicity of therapeutic chemicals: How do you
evaluate effects that may show up only as subtle functional
disturbances? And how do you de tect toxic effects early enough so
that they may still be reversible, before they produce major
damage? The contributions in this book come from a collection of
scientists whose interests span a wide variety of problem areas.
The focus is largely on me thodological issues because they
represent the most immediate concern of the discipline. We expect
that this collection of papers will represent a useful source book
for behavioral toxicology for some time. For the past few years,
the University of Rochester's Department of Radiation Biology and
Biophysics has sponsored a series of international conferences on
chemical toxicity, partly as a response to concern over the con
sequences to health of the rich chemical soup in which we live.
This book is based upon presentations made to the fifth of the
series. Held in June, 1972, it was the first formal meeting devoted
to behavioral toxicology in this country."
