Training Munitions Health Risk Assessment NO. 39-EJ-1485-00 Residential Exposure from Inhalation of Air Emissions from the 155-MM Propelling Charge (M3 Series) Department of Defense Identification Code: D540

This assessment evaluated the potential for human health effects to off site residents breathing air emissions following use of the 155 mm Propelling Charge This document present the evaluation of the potential for adverse human health effects to the off site residents breathing air emissions following the use of military firing ranges during training exercises - Study results showed no potential for health risks to the hypothetical resident from inhalation of air emissions from the 155 mm propelling charge. To conduct this study, air emissions from the 155mm charge were collected in a test chamber ( at Aberdeen Test Center, Aberdeen, MD). This information was then used in an air dispersion model to determine ambient air concentrations at a location downwind from the site where the item was activated. Modeled air concentrations were combined with exposure information to estimate the amount of substances the hypothetical resident breathes.
