Inspectors found that oil had leaked into the port’s water area, forming a slick measuring approximately 400 by 200 meters on the surface. Emergency crews deployed containment booms to prevent the spread of the oil, while port services blocked stormwater drainage systems to stop further leakage into the sea. No soil contamination was recorded, as the affected area is covered with concrete, the inspection said. Environmental specialists have taken seawater samples for laboratory testing to determine the extent of the ecological threat and calculate damages. Authorities said a full assessment of environmental harm caused by the attack would be completed once all necessary data is collected. The Black Sea has repeatedly faced environmental risks since the start of Russia’s full-scale invasion, with strikes on port infrastructure raising concerns over long-term ecological damage. The sunflower, despite being endemic to the US Southwest and western Mexico according to the UK’s Royal Botanic Gardens , is the national flower of Ukraine, which produces 23% (about 4.6 million tons in 2025) of the world’s oil from the seeds, and leads the world in exports at 33% (4.4 million tons of the oil last year).
