Abstract
Petroleum products are introduced into the environment through a variety of mechanisms and are shown to produce highly reactive oxygen species though photochemical reactions. For example, potential contamination can occur from motor oil leaked or spilled by recreational water vehicles such as boats and jet skis. Motor oils, both synthetic and non-synthetic, can produce potentially toxic components through natural weathering processes. Chemicals produced through photochemical processes are examined to help assess overall ecosystem impact and better understand mechanisms of toxicity. This study examined photochemical degradation and subsequent toxicity of both crude oil and water collected from local marinas. Using a high performance liquid chromatography (HPLC) method for detection of hydroxyl radical (·OH ), benzoic acid was added to each sample prior to irradiation. Benzoic acid served as a radical trap for OH produced. The resulting formation of para-hydroxybenzoic acid (p-HBA) was measured and total ·OH formation determined.
