This summary has been compiled to help address concerns regarding the potential of air emissions from large-scale composting facilities to impact the health of neighbors. I have attempted to summarize and provide citations to all of the relevant journal articles and published governmental reports. Much of the available literature addresses on-site investigations that are relevant to worker health. Some of the literature on worker health is summarized here because of its relevance to neighbor impacts. However, no attempt has been made to comprehensively address worker health related to air emissions at compost facilities. A chapter in the up-dated On-Farm Composting Handbook (expected publication in 2007) will address worker health considerations. This summary does not include a comprehensive review of odor or volatile organic compound studies.
