### Environmental Monitoring  
AI for Air and Water Quality Monitoring  
AI-powered systems for air quality monitoring utilize a combination of sensor networks, data analytics, and ML algorithms to track and analyze pollutants such as sulfur oxides (SO\({}_{\mathrm{x}}\)), nitrogen oxides (NO\({}_{\mathrm{x}}\)), carbon dioxide (CO\({}_{2}\)), and particulate matter (PM). These systems can continuously collect data from various locations around the port, providing a comprehensive picture of air quality [185; 186; 187]. ML algorithms process these data to identify patterns and trends, enabling the detection of pollution sources and the assessment of their impact on air quality. For example, AI can correlate spikes in certain pollutants with specific port activities, such as ship arrivals, cargo-handling operations, or vehicle traffic. This level of insight allows port authorities to implement targeted measures to reduce emissions, such as optimizing vessel schedules to minimize idling or promoting the use of cleaner fuels [188; 189; 190]. Additionally, AI systems can integrate with weather prediction models to forecast air quality conditions, helping port authorities prepare for and mitigate potential pollution events. Real-time alerts can be generated when pollutant levels exceed safe thresholds, prompting immediate actions to protect public health and the environment [191; 192]. Similarly, AI enhances water quality monitoring by providing advanced tools for detecting and analyzing contaminants in port waters. AI systems can integrate data from various sensors that measure parameters such as temperature, pH, dissolved oxygen, turbidity, and concentrations of harmful substances like heavy metals, oil, and chemicals [183; 193]. ML models can analyze these data to identify deviations from normal water quality conditions and predict potential contamination events. For example, AI can detect early signs of oil spills or chemical leaks by recognizing abnormal patterns in sensor readings. This early detection enables prompt response efforts, minimizing environmental damage and facilitating quicker cleanup operations [194; 195]. Moreover, AI can enhance the spatial and temporal resolution of water quality monitoring by using data from remote sensing technologies such as satellites and drones. These technologies provide high-resolution imagery and data over large areas, allowing for comprehensive monitoring of coastal and marine environments [196; 197]. AI-driven predictive models are essential tools for conducting environmental impact assessments (EIAs) in the maritime industry. These models use historical data, real-time monitoring information, and advanced analytics to predict the environmental consequences of port activities and infrastructure projects [198; 199]. Modeling Environmental Impacts  
Predictive models can simulate various scenarios to assess the potential impacts of different port operations, such as dredging, construction, and increased shipping traffic. By inputting data on current environmental conditions, proposed activities, and projected growth, AI models can forecast changes in air and water quality, noise levels, and ecosystem health [200; 201]. For example, AI models can predict how dredging activities might affect sediment dispersion and water turbidity, which in turn can impact marine life and habitats. Similarly, these models can estimate the cumulative impact of increased shipping traffic on local air quality and public health [202; 203]. The insights generated by predictive models provide valuable decision support for port authorities and policymakers. By understanding the potential environmental impacts of proposed activities, stakeholders can make informed decisions and implement mitigation strategies to minimize adverse effects. For instance, AI models can help identify the most environmentally friendly locations for new port infrastructure or suggest optimal times for conducting certain activities to reduce their impact [204; 205; 206; 207].
