In this episode host Mark Reggers and guest Jen Hines, Consultant Occupational Hygienist and Lecturer at the University of Wollongong continue where they left off and resume their discussion on the subject matter of diesel particulate matter. Diesel particulate matter is the particle substance within diesel exhaust. It is a carcinogenic combination of particulates and gases that are detrimental to one’s health. Occupational exposure can present itself in the form of short term acute effects such as eye and respiratory irritation through to long term chronic conditions like heart and lung disease.
