There are numerous uncertainties associated with environmental health risk assessment (EHRA), and it is unavoidable to apply the best models and information available to save human lives. The EHRA is a method for determining the type and likelihood of adverse health effects on people who are exposed to chemicals in the workplace. To address the environmental health problems caused by harmful gas leakage and water pollution generated by the coastal regional chemical industry, a novel EHRA model for the coastal chemical industry has been developed. The premise of the Gauss plume diffusion model is used to define the model's parameters and the evaluation criterion for harmful gas concentration health risk. The EHRA model is evaluated against the leakage of harmful gases and consists of three steps. The first step is to identify the threat posed by the chemical industry in the coastal region; the second step is to quantify the risk; the third step is to develop a model for assessing water-related environmental health risk. The water-related environmental health assessor analyzes the pollutant variables and parameters of the assessment model to estimate the health risk caused by dangerous compounds in the water, using the assessment model of chemical carcinogen health risk and noncarcinogen health risk Type B. The experiments' findings suggest that the model can effectively assess the dangers to human health from hazardous gases and heavy metals in the water bodies of chemical factories in coastal communities.
环境健康风险评估（EHRA）存在许多不确定性，因此，不可避免地需要应用最佳模型和现有信息来拯救生命。EHRA 是一种确定因工作场所接触化学物质而对人体产生不利健康影响的类型和可能性的方法。为了解决沿海地区化工行业有害气体泄漏和水污染所引发的环境健康问题，开发了一种新型沿海化工 EHRA 模型。该模型以高斯烟羽扩散模型为前提，定义了模型参数和有害气体浓度健康风险评估标准。该 EHRA 模型针对有害气体泄漏进行评估，包括三个步骤。第一步是识别沿海地区化工行业的威胁；第二步是量化风险；第三步是开发水相关环境健康风险评估模型。水相关环境健康评估师分析评估模型的污染物变量和参数，以估算水中危险化合物对健康造成的风险，使用化学致癌物健康风险评估模型和非致癌物健康风险 B 型。实验结果表明，该模型可以有效地评估沿海社区化工厂水体中有害气体和重金属对人体健康的危害。
