Psychology is the science of behavior and mind, including conscious and unconscious phenomena, as well as feeling and thought. It is an academic discipline of immense scope and diverse interests that, when taken together, seek an understanding of the emergent properties of brains, and all the variety of epiphenomena they manifest. As a social science it aims to understand individuals and groups by establishing general principles and researching specific cases.

Unlike the physicist, the psychologist … investigates processes that belong to the same order — perception, learning, thinking — as those by which he conducts his investigation.
Human activities have strongly modified the biogeochemical cycles of metallic trace elements (MTEs) increasing their fluxes towards and between surface environments. New isotope data has fostered better models of MTE sources, transfer and reactivities in dynamic and multi-sources systems, as required for targeting emission controlled strategies to combat origins and consequences of metal contamination.
