Oil spills in ports are particular cases of oil pollution water environments that call for specific monitoring measures. Apart from the ecological threats they pose, their proximity to human activities and financial losses induced by disturbed port add need immediate action. However, ports, established methods based on short-wave infrared sensors might not be applicable due relatively low thickness layer, satellite images suffer insufficient spatial resolution, given agglomeration objects ports. In this study, a lightweight ultraviolet (UV) camera was exploited both controlled experiments real environment estimate potential limitations UV imagery detecting spills, comparison RGB images. Specifically, motivated scarce research literature topic, we set up simulating with various types, different viewing angles, under weather conditions, such separability between background (water) could better understood objectively assessed. The also used detect real-world after installing it vessel continuous monitoring. Various metrics oil, computed scenarios (controlled environment), show cameras have than environments.

The global issue of oil spreading in water poses a significant environmental challenge, emphasizing the critical need for accurate determination and monitoring content aquatic environments to ensure sustainable development environment. However, complexity arises from challenges such as dispersion, clustering, non-uniform distribution, making it difficult obtain real-time concentration data. This paper introduces sophisticated system acquiring induced fluorescence spectra specifically designed quantitative analysis pollutants. involved measuring across 20 gradients (ranging 0 1000 mg/L) four distinct samples: 92# Gasoline, Mobil Motor Oil 20w-40, Shell 10w-40 engine oil, Soybean Oil. research focused on establishing relationship model between relative intensity concentration, determined at optimal excitation wavelength, utilizing segmented Random Sample Consensus (RANSAC) algorithm. Evaluation metrics, including standard addition recovery, average error, were employed assess accuracy proposed model. experimental findings suggest that recovery rates samples ranged 99.61% 101.15%, with errors falling within range 2.04% 3.14%. These results underscore efficacy detection methodology presented this paper. Importantly, extends scenarios involving heavier pollution. exhibits exceptional sensitivity, enabling precise diverse spills 0~1000 mg/L bodies, offering valuable insights quality
