TY - JOUR PY - 2020// TI - Development on health risk assessment method for multi-media exposure of hazardous chemical by chemical accident JO - International journal of environmental research and public health A1 - Hong, Hyong Jin A1 - Park, Si Hyun A1 - Lim, Hui Been A1 - Lee, Cheol Min SP - e17103385 EP - e17103385 VL - 17 IS - 10 N2 - In this study, a long-term health risk assessment was conducted for complex, multimedia exposure where the exposure duration was set for the leak of a hazardous chemical spilled after an accident. The study designed a virtual chemical accident scenario where 40 tons of benzyl chloride leaked in a factory inside the Ulsan Petrochemical Industrial Complex for one hour on 1 January 2017. Using a multimedia environmental dynamics model, benzyl chloride concentrations in air and soil were estimated. The time when the atmospheric concentration was less than or equal to the background concentration was recorded as the end point. An assessment of the cancer risk via soil ingestion was carried out after dividing the subjects into four age groups (0-9 years; 10-18 years; 19-65 years; >65 years). All age groups showed an increased cancer risk where the values exceeded 1.0 × 10-6. The 0-9 years age group showed the largest distribution (4.27% of the total area) with the highest maximum and mean values. The distribution maps for all age groups exhibited a trend towards the southeast of the accident site.
