title: Particulate environmental matter as seen in lung sections.
abstract: A study of particulate environmental matter as seen in lung sections is presented. These particles are blackened and are comparable to particles seen in industrial-urban environments. From the study of histologic sections an attempt is made to determine the tissue reaction to them and their ultimate fate.
