Risk of physical symptoms accoding to the level of urinary VOCs and PAHs metabolites and metals in 154 residents pariticipating in clean-up of the Hebei Spirit oil spill, Taean, Korean, 2007-2008.

Physical symptoms 1: eye irritation, 2: visual disturbance, 3: nasal irritation, 4: sore throat, 5: bronchial irritation, 6: dermal irritation, 7: headache, 8: palpitation, 9: nausea/vomiting, 10: abdominal pain, 11: fatigue/fever, 12: musculoskeletal symptoms, 13: memory/coginitive disturbance, 14: back pain.

MA: t,t-muconic acid, MnA: mandelic acid, HA: hippuric acid, mHA: methyl hippuric acid, 1-OHP: 1-hydroxypyrene, 2-Naphthol: β-naphthol, Pb: lead, Hg: mercury, Mn: manganese, Ni: nickel, Cd: cadmium, VOCs: volatile organic compounds, PAHs: polycyclic aromatic hydrocarbons.

Odds ratio and 95% confidence intervals of people whose urinary level was in the upper half referenced by those with levels in the lower half, estimated using multiple logistic regression model adjusted for age, gender, history of asthma diagnosed, health belief regarding oil spill.

Statistically significantly increased risk of physical symptoms in individuals whose urinary level was in the upper half compared to those with levels in the lower half.
