Discourse Studies is a bimonthly peer-reviewed academic journal that covers the field of discourse analysis, especially articles that offer a detailed, systematic and explicit analysis of the structures and strategies of text and talk, their cognitive basis and their social, political and cultural functions. It specifically also publishes studies in conversation analysis. The journal was established in 1999 by Teun A. van Dijk.
Metals released into the atmosphere from human activities pose a significant risk to ecosystems and human health. Small airborne particles with a diameter of less than 10 microns can be inhaled and then absorbed into the alveolar tissue of the lungs, resulting in damage.
