Abstract

This study investigated seasonal and meteorological factors affecting the concentration levels of 1,2-dichloroethane, benzene, and 1,3-butadiene and conducted health risk assessments inside and outside the industrial estate in Rayong Province, Thailand. Volatile organic compound concentrations and meteorological data from 2019 to 2023 were analysed. Temperature and relative humidity showed a medium-level linear relationship with the concentration of 1,2-dichloroethane at Wat Nong Fab (R² = 0.549, p < 0.01). Inhalation exposure of 1,3-butadiene posed the highest risk in the cold season (hazard quotient (HQ) = 7.949), with an annual average HQ of 2.72. Therefore, the controlling exposure to 1,3-butadiene and tracking health outcomes when exposure occurs is paramount, especially during the cold season.

影响工业园区内外挥发性有机化合物浓度分布和健康风险评估的季节影响和气象因素：以泰国罗勇省为例

本研究调查了影响1,2-二氯乙烷、苯和1,3-丁二烯浓度水平的季节和气象因素，并在泰国罗勇省的工业园区内外进行了健康风险评估。分析了2019 - 2023年的挥发性有机化合物浓度和气象数据。Wat Nong工厂温度和相对湿度与1,2-二氯乙烷浓度呈中等水平线性关系(R2 = 0.549, p <；0.01)。1,3-丁二烯吸入暴露在寒冷季节的风险最高，危害系数(HQ) = 7.949，年平均HQ为2.72。因此，控制1,3-丁二烯暴露并在暴露时跟踪健康结果至关重要，特别是在寒冷季节。
