Environmental Geochemistry
is the study of the geologic processes
that interact strongly with the materials
present in the Earth’s crust.
The geologic processes:
T weathering of rocks,
w soil formation,
s solutes in surface and ground water,
s global atmospheric transport of
particulate matter,
p global cycling of contaminant
products.
