Abstract: The paper shows heavy metal (mercury) concentrations at selected points. The data was collected using the remote sensing method from the EMODnet network. The Mediterranean region was analyzed. The measured values were detected in sediments, water and biota. The paper presents the mechanism of mercury movement in the marine environment. Cases where the toxic effects of mercury were detected in the marine environment are discussed. The impact of mercury pollutants on the food chain in the sea is particularly emphasized. The highest measured mean values of mercury in sediments are in points 10 (71710.51), point 8 (6130.0; 4715.0) and point 5 (37794.0; 36805.0; 35061.0; 18279.0); in the biota at point 1 (311.0); in water at points 3 (0.05), point 6 (0.01), point 5 (0.01), point 4 (0.01) and point 2 (0.01).
