Summary: | The article reports the results of the summer 2018 expedition to Cape Kamenny(of the Ob bay, Yamalo-Nenets Autonomous Region) and the nearby non-functioning oil product supply facility (OPSF).The aim of the study was to monitor the current environmental situation and assess the level of oil pollution of environmental objects on these territories. The field and laboratory studies revealed the need to treat and remediate the oil-polluted soils, water bodies and wetlands.The field surveys of the territories showed the presence of visible oil polluted sites. The results of the laboratory tests revealed an excess of maximal permissible concentration (MPC) levels (1.3 – 6.2 MPC) for the water bodies located near the sources of oil pollution. The soil samples near the OPSF demonstrate a significant excess of oil products content (up to 1474 times). The soils sampled at Cape Kamenny are characterized by smaller content of oil products.Since the non-functioning OPSF is situated on a territory that has always been poluted by oil, it seems necessary to develop a land remediation plan to rehabilitate the site and to prevent a further pollution of the adjacent territories due to the migration of the pollutants.The oil pollution levels established for Cape Kamenny territory indicate a fairly high level of anthropogenic pressure in this area. Due to the low comparatively low soil stability in the area, it appears necessary to augment the measures for controlling the oil products leakage and spills at all the potentially hazardous objects. Проведен мониторинг нефтяного загрязнения объектов окружающей среды на территории п. Мыс Каменный и расположенного поблизости нефункционирующего объекта нефтепродуктоснабжения. Целью исследования являлась оценка уровня нефтяного загрязнения объектов окружающей среды на территории природно-антропогенных комплексов западного побережья Обской губы в районе п. Мыс Каменный. Определены уровни загрязнения объектов окружающей среды нефтью и нефтепродуктами, установлены превышения величин ПДК для отдельных точек экологического мониторинга. Рекогносцировочные и камеральные исследования выявили необходимость проведения мероприятий по рекультивации нефтезагрязненных участков. |
