A whole population of a community affected 23 24 by an anthropogenic environmental disaster. 25 26 Participants: 63,053 individuals (male: 31,636; female: 31,417) and 3,420 individuals (male: 27 28 1,805; female: 1,615) from two counties, respectively 29 30 31 Interventions: None. Observational study on the effect of a specific environmental health 32 33 hazard. 34 35 Primary and secondary outcome measures: BOD was measured using disability-adjusted http://bmjopen.bmj.com/ 36 37 life-year (DALY) method based on the incidence and prevalence of the health outcome 38 39 40 related to the oil spill. 41 42 Results: Years lost due to disabilities (YLD) attributable to the oil spill were estimated to be 43 on October 1, 2021 by guest.

The YLD for 45 46 males for mental diseases were higher than for females, and the YLD for females was higher 47 48 in asthma and allergies than for males. The effects of asthma and allergies were the greatest 49 50 51 for people in their 40s, with the burden of mental illness being the greatest for those in their 52 53 20s. Proximity to the spill site was associated with increased burden of disease. 54 55 Conclusions: An oil spill near a coastline can cause substantial adverse health effects.

This was 17 18 19 the largest oil spill in the history of Korea. Spilled oil contaminated over 1,000 km of the 20 21 western coast of Korea including the Taean Coast National Park.[1] Crude oil contains 22 23 various volatile organic compounds (VOCs) such as benzene, toluene, ethylbenzene, xylenes, 24 25 and polycyclic aromatic hydrocarbons (PAHs),[2] all of which are potential air-borne toxins. 26 27 Certain VOCs, benzene in particular, are carcinogenic to humans and are associated with 28 29 30 haematologic cancer.[3] Previous studies [4-11] have reported that oil spills have caused 31 32 adverse health effects for residents of contaminated areas and clean-up workers. Risk 33 34 analyses revealed that more frequent clean-ups and greater exposure to oil are strongly 35 http://bmjopen.bmj.com/ 36 associated with higher frequencies of psychological symptoms. [8-11] Rodriguez-Trigo [6] 37 38 39 reported that participation in a major oil spill clean-up is associated with chromosomal 40 41 damage, although they were unable to determine whether oil exposure itself caused the 42 43 abnormalities. on October 1, 2021 by guest.
