Definitions – Terminology …Environmental Geochemistry
is the study of the geologic processesthat 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.
