Impact of surrogate selection on risk assessment for total petroleum hydrocarbons

摘要: Abstract Environmental contamination involving total petroleum hydrocarbons (TPH) is being investigated and remediated at underground storage tanks, tank farms, pipelines, refineries across the country. Human health environmental risk play a significant role in decision making these sites. However, assessment for sites contaminated with products typically complicated by inadequate information about composition of TPH present site physical chemical properties toxicity components. To address data gaps, assessors can select surrogate compounds to represent movement environment site. This article illustrates potential impact choice surrogates on estimates, which turn affect remediation costs.
