Abstract

We would like to alert toxicologists to the importance of testing for gasoline, and for volatile hydrocarbons in general, in deaths involving inhalation of exhaust fumes occurring in closed spaces with running motors or machinery. We present here a case of suicidal inhalation of motorbike exhaust, a mixture of carbon monoxide (CO) and gasoline vapor, by a 38-year-old female. She was found in her closed home garage with a hose extending from the exhaust pipe of a motorbike through a cellophane plastic device into a closed tent in which the victim lay. She left two suicide notes nearby. The carboxyhemoglobin (COHb) was measured using visible spectrophotometry. The toxicological screening and quantitation of gasoline was performed by means of gas chromatography with flame-ionization detector and confirmation was performed using gas chromatography-mass spectrometry. The %COHb determined in blood was 73%. Gasoline concentrations in heart blood and vitreous humor were 22.3 and 1.0 mg/L, respectively. Although fatalities with CO at this rate are common, we would like to highlight the role of gasoline and add new quantitative data of this toxic substance to the scarce literature. Based upon the toxicological data, along with the information provided by the medical examiner, the cause of death was determined to be CO and gasoline poisoning and the manner of death suicide.
