Abstract : The primary objective of the research presented herein was to develop oral risk factors for long chain petroleum hydrocarbons (LCPHs). Literature searches were conducted on petroleum products and specific LCPHs. Over 5,000 references were identified and over 100 references were reviewed. Information was collected on the chemical composition and analysis of total petroleum hydrocarbons (TPH); the environmental regulation of TPH in soils; the weathering of TPH in soils; risk factors previously developed for neat petroleum products and four LCPHs; and on the toxicity of LCPHs. Oral reference doses were developed for nonane, decane, C10-C11 isoparaffmic hydrocarbon dearomatized white spirit C11 -C12, mineral oil, and petroleum wax. Gaps in the data necessary for the development of risk factors for LCPHs were identified and suggestions were made for future research to elucidate risk assessment at petroleum contamination sites. In addition, four DoD sites were identified for potential demonstration of risk assessment and risk-based cleanup versus cleanup based on regulatory standards for soils.
