Contamination of the earth's ecosystems by potentially toxie
metalsl metalloids is a global problem. It will likely grow with
our planet's increasing populations and their requirements for
natural resources (e. g. , water, food, energy, waste-disposal
sites) and metals-based goods. The health impacts of pollution from
the ingestion of heavy metals/metalloids via respiration, food, and
drinking water are most often long-term and manifest themselves in
many ways. These include, for example, disminution of mental
acuity, loss of motor control, critieal organ dysfunction, cancer,
chronie illnesses and con- comitant suffering, incapacitation, and
finally death. The incidence and geographie distribution of disease
(epidemiology) has been well-documented historieally and in modern
times for toxic metals- triggered diseases in humans, animals and
vegetation. The role of the environmental geochemist and colleagues
in environ- mental sciences is to scientifically evaluate how to
manage metalsl metalloids at sources or in-situ so as to alleviate
or eliminate their negative health impacts on living populations.
This is initiated by identifying sources and by developing models
of the physieal, chem- ieal and biologieal controls on
mobilization, interaction, deposition and accumulation of
potentially toxie metals/metalloids in source systems and earth
ecosystems. Prom this knowledge base, environ- mental scientists
(e. g. , geologists, chemists, biologists, environmen- tal
engineers, physicists/meteorologists) work together to develop
Preface VI concepts and technologieal methodologies to preserve
global eco- systems. Their concerted efforts are equally focussed
on devising strategems to remediate ecosystems still carrying heavy
metals/metal- loids pollutant burdens from ancient and modern
societies.
