Michael S Morgan, DSc
About
Since earning his advanced degree in Chemical Engineering (MIT) and receiving post-doctoral training in Respiratory Physiology (Harvard School of Public Health), Dr. Morgan has spent thirty-seven years teaching and studying the human response to inhalation of air contaminants, including the products of combustion and volatile solvents. His research has encompassed both ambient air contaminants and occupational environmental health hazards. He is also past Chairman of the Biological Exposure Indices Committee of the ACGIH, and was Editor-in-Chief of the Journal of Occupational and Environmental Hygiene until 2010.

Bioavailability of Chromium VI Compounds from Airborne Exposure: Influence of Work Process Variables.
The objective of this project is to determine the levels of chromium in the urine of workers performing different operations involving materials containing chromium VI (Cr VI), and to investigate the influence of airborne particle size, chromium species solubility, and chromium-bearing matrix on the ability of Cr VI compounds to enter the circulation after inhalation. The overall hypothesis is that the bioavailability of inhaled Cr VI is strongly affected by each these variables in a manner that can be predicted from our current understanding of particle deposition in the respiratory system, particle solubility in body fluids, and the role of an encapsulating matrix in determining the solubility.
