Learning objectives
<br />The feeling and culture of environment are only acquired in touch with the Nature <br />Teaching of Geochemistry intends to provide <br />(i)basic concepts for interpretation of the originand evolution of soiland surface and ground waters, and water-rockinteraction;<br />(ii) geochemical description of some natural systemsand processes;(iii) examples of the use of geochemistry in environmentmonitoring.
