Introduction

The prediction of environmental contaminant spread is a critical area of research with significant implications for public health, ecological preservation, and emergency response. Machine learning and artificial intelligence techniques have emerged as powerful tools for addressing the complexities of contaminant dispersion across various environmental media. These advanced computational methods enable more accurate and timely forecasting, which is essential for effective mitigation and management strategies. The rapid advancements in data collection and processing capabilities have further fueled the development and application of these predictive models. Machine learning models, particularly deep learning architectures and ensemble methods, are revolutionizing the accuracy and speed of predicting the spatial and temporal spread of environmental contaminants. By analyzing complex datasets encompassing atmospheric conditions, hydrological patterns, and emission sources, these techniques forecast contaminant plumes and inform emergency response. The integration of diverse data streams is emphasized for more precise predictions [1].

Artificial intelligence, specifically algorithms like random forest and gradient boosting, are proving effective in modeling the dispersion of airborne pollutants. These models assess contaminant concentrations under various meteorological scenarios, enabling real-time risk assessment and public health advisories. Feature selection is highlighted as crucial for improving model performance [2].

Convolutional neural networks (CNNs) are being investigated for their ability to predict the spread of waterborne contaminants from industrial discharge. By analyzing spatial-temporal patterns in water quality and hydrological data, CNNs can forecast the extent and persistence of contamination events, capturing intricate spatial relationships valuable for water resource management [3].

Recurrent neural networks (RNNs), including Long Short-Term Memory (LSTM) networks, are employed for forecasting the long-term spread of soil contaminants after accidental spills. These networks leverage historical data and environmental parameters to predict future contaminant migration patterns, effectively modeling sequential dependencies for long-term environmental risk assessment [4].

Hybrid approaches combining geographical information systems (GIS) with machine learning algorithms, such as support vector machines, are being used to predict the spread of hazardous materials in urban environments.

Ensemble learning techniques, including stacking and bagging, are being utilized to enhance the robustness and accuracy of predicting microplastic contamination spread in marine ecosystems. These methods analyze oceanographic data and current patterns to forecast microplastic distribution, demonstrating that ensemble approaches reduce prediction variance and improve overall model performance [6].

Fuzzy logic and neural networks are being integrated to predict the spread of chemical contaminants through complex geological formations. This approach combines geological survey data, hydrological flow, and chemical properties to model contaminant transport, offering improved predictive capabilities for subsurface contamination scenarios [7].

Bayesian networks are explored for probabilistic modeling of radioactive contaminant spread following nuclear accidents. These networks incorporate uncertainty quantification from meteorological data and source term estimations to provide probabilistic dispersion assessments, which are vital for risk management in emergency situations [8].

Deep reinforcement learning (DRL) is being applied to optimize sensor placement for real-time monitoring of airborne contaminant spread. DRL develops intelligent sensor networks that adapt to changing environmental conditions, ensuring optimal coverage for early detection and tracking of pollutant plumes, demonstrating DRL's potential for dynamic monitoring systems [9].
