Abstract
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.

To mitigate the environmental health risk caused by the coastal chemical sector, it is necessary to build and develop an environmental health risk assessment model
Environmental health risks under the development of coastal chemical industry mainly include environmental risks caused by harmful gases and environmental pollution caused by harmful substances in water [16]
Summary
Received 4 July 2021; Revised 2 September 2021; Accepted 26 October 2021; Published 10 November 2021. 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. E 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. Rough rivers, groundwater, and the atmosphere, a large amount of land-based pollution is concentrated in the coastal areas, resulting in water quality deterioration, ecosystem change, and red tide disasters. Since the 1980s, the marine ecological environment in China has been seriously damaged due to the sharp increase of land-based pollutants and the overdevelopment of coastal waters [4]. The deterioration of the marine ecological environment has an initial impact on the economy of China’s coastal areas
