This study aims to consider all the inherent variables to the compounds due to their disposal in the environment, relating their fate associated to their toxicological risk and verify the influence of considering all the petroleum hydrocarbons range in the risk evaluation, quantifying the uncertainty of a classic risk evaluation.The risk simulations performed for the BTEX compounds indicated values above the limits accepted by the environmental agencies only for a hypothetical scenery regarding explotation of water nearby the PPTX 070 well area. The other scenaries presented acceptable risk limits.The quantification of the toxicological risk associated to all the petroleum hydrocarbons range presented more restrictive values than the evaluations performed for the same water sample, when it was considered only the standardized compounds (BTEX). The variations went up to two greatness orders in the risk quotient.Thus, the definition of remediation goals and adoption of a specific management program must consider all the petroleum hydrocarbons range and not only standardized compounds.
