Ch.1. Introduction
Environmental Geochemistry?The application of chemical principles to
predicte the fate of organic and inorganic pollutants at the earth's surface and in the atmosphere (R.Stoessel)
Applying geochemical knowledge to solve environmental problems
Ch.1. Some Concepts for EG
Earth is a closed but dynamic system It stays in the system but cycles through the system (e.g. rock cycle, water cycle, sulfur cycle, etc.)
Earth is practically the only home for human beings within our reach in the Universe
Need to balance development with conservation Sustain-ability!!
Environmental impact may seem little before getting the criti-cal point
A lot slower recovery than pollution, which is of course ex-tremely expensive Problems for generation after generation
Recovery (restoration, remediation) is never perfect. Environmental Science is a comprehensive study field
Various matter cycles in the Earth system
