Opis:
Computer simulations used for predicting the behavior of oil spills at sea allow optimizing the deployment of oil spill response personnel and resources, and using the backtracking method to identify the polluter in cases where spills are sighted some time after they occurred. Predicting the direction and speed of oil slick spreading is of fundamental importance. An attempt was made to verify the influence of selected simulation parameters, related to hydrometeorological conditions, on the behavior of the resulting oil pollution. Different responses were obtained under the same simulated weather conditions, depending on the type of spilled oil. The experiment was conducted on a PISCES II oil spill simulator.

Opis:
The ability to use computer simulation to predict the behavior of oil spills at sea enables better use of available personnel and resources to combat such spills. The use of oil collecting equipment properly selected to suit the conditions is essential for the operation to be effective. Therefore, an attempt is made to verify the influence of weather conditions on the efficiency of oil recovery. Three types of spilled crude oil were simulated. A relevant experiment was conducted on a PISCES II oil spill simulator.
Możliwość wykorzystania symulacji komputerowej do prognozowania zachowania się rozlewów olejowych na morzu umożliwia lepsze wykorzystanie posiadanych sił i środków służących do ich zwalczania. Zastosowanie odpowiednio dobranego do warunków sprzętu jest istotne z punktu widzenia efektywności prowadzonej akcji. W związku z tym podjęto próbę weryfikacji wpływu warunków meteorologicznych na skuteczność usuwania powstałego zanieczyszczenia olejowego. Zasymulowano rozlewy trzech typów ropy naftowej. Eksperyment przeprowadzono w symulatorze rozlewów olejowych PISCES II. Przeprowadzone symulacje wykazały istotny wpływ rodzaju ropy na skuteczność akcji usuwania zanieczyszczeń z powierzchni morza, im lżejsza ropa tym zbieranie przebiega w mniejszym stopniu z uwagi na jej rozpraszanie i utlenianie. Ropa ciężka tworzy grubą warstwę na powierzchni wody, może ulegać emulsyfikacji, wolniej ulega procesom utleniania, co prowadzi do efektywnego jej zbierania. Doświadczenie ukazało wpływ warunków meteorologicznych na sprawność zbierania ropy, przy wysokości fali 0 i 1 m usuwanie ropy za pomocą skimmera pasowego było skuteczne, a fala o wysokości 2 m uniemożliwiała usuwanie zanieczyszczeń ropopochodnych z powierzchni wody bez względu na jej rodzaj.

Opis:
The topic of the publication is the description of the method of quick detection and identification of pollution derived from oil on the water surface. This method is based on the teledetection technique. It is based on the application of a teledetection head, which consists of a digital camera working in a 300 - 1100 nm range and equipped in a suitable filter. The point is to receive digital imageries in several spectral ranges, and processing them in such a way to get an appearance of a polluted area on the imagery. It is possible because of using different reemission characteristics of polluted water surface and water surface free from pollution.

Opis:
This study assesses the physiochemical characteristics and heavy metals content of crude oil polluted soils and non-polluted soils from Ohaji/Egbema, Imo State. Soil samples were collected at depths of 0-30 cm at each sampling point and then analyzed using standard analytical methods. Data from the five areas were compared to standards for soils in Nigeria and in World Health Organization (WHO) data banks. The results obtained from the analysis showed an average pH of (4.88 ± 0.02 to 5.02 ± 0.04) for polluted soil and (6.57 ± 0.05 to 6.82 ± 0.03) for non-polluted soil, electrical conductivity (571 ± 1.1 to 592 ± 0.8 µS/cm) for oil polluted soil and (383 ± 0.5 to 415 ± 1.6 µS/cm) for non-polluted samples, moisture content (5.2 ± 0.2 to 9.1 ±0.1 %) for polluted soil and (4.5 ± 0.1 to 4.7 ± 0.3 %) for non-polluted soil samples. There was no significant difference in temperature and organic matter for both the polluted and non-polluted soil samples. The heavy metals analysis results showed Fe3+ (0.615 to 0.989 ppm) for oil-polluted soil samples and (0.0453 to 0.273 ppm) for non-polluted soil samples, Pb2+ (0.017 to 0.180 ppm) for oil-polluted soil and (0.008 to 0.010 ppm) for non-polluted soil. The study reveals that areas that are polluted need urgent remediation if the soil is to be used for agricultural purposes.

Opis:
According to many intenstigations, oil pollution cause difficult changes of structure and function of natural ecosystems, as well as violation of metabolic processes, production and destruction of organic matter, and consequently leads to a decrease in species diversity. Studies show that planktonic animals are quite sensitive to oil pollution of sea water, which accelerates their death in the concentration of 0.01 mg·dm-3.

Opis:
The effects of crude oils entering marine environment have been investigated since early 1960s when oil pollution became a subject of global environmental concern. Extraction and transportation of crude oils have been contributing to water pollution especially in closed water basins, such as the Baltic Sea. It was estimated that yearly oil input to the Baltic Sea amounts to 21-70 thousands of tons, which is twice higher than in the North Sea and three times higher than in the North Atlantic. Growing pollution loads into the Baltic Sea created a demand for multifarious studies on the environmental effects of oil products. In this study, we focus on bio-optical and ecological aspects of the presence of crude oil in seawater. Dispersed oil droplets occur in seawater as the result of contaminated river inflows, bilge water discharges and as the consequence of mechanical and chemical dispersion of oil spills. Their optical properties depend on oil type, concentration and size distribution. We present further results obtained from the developed fluorescence-based method for determination of the crude oil concentration in natural Baltic seawater and for evaluation of the oil droplets size by applying vacuum filtering. The results have been measured for the samples collected in Southern Baltic Sea during several ship cruises in 2012. We discuss the application of vacuum filtering in the fluorescence analyses in the context of laboratory, in situ and remote detection of dispersed oil.

Opis:
Despite of numerous actions undertook by the global and local authorities towards protection of marine environment, oil pollution loads into the Baltic Sea still tend to increase and need to be continuously estimated in order to apply the legal regulations. There is a demand for multifarious studies on the environmental effects of oil products. Dispersed oil droplets occur in seawater as the result of contaminated river inflows, bilge water discharges and as the consequence of mechanical and chemical dispersion of oil spills. Their optical properties depend on oil type, concentration and size distribution. Oil content influences many environmental factors, like water quality and bio-optical parameters (e.g. water-leaving radiance, inherent optical properties, seawater fluorescence). We present a unique study of the collected database of crude oil fluorescence spectra for better understanding the correlations between oil optical properties and its concentration, as well as for evaluation of the oil droplets size by the application of vacuum filtering using three filters of different permeability. Fluorescence spectra have been registered for oil-in-water emulsion samples prepared in the laboratory by mechanical dispersion. We discuss the optical properties of crude oil and the relationships between them in the context of potential remote detection of dispersed oil in seawater.

Opis:
Lake Saimaa is the largest lake in Finland and the Saimaa inland waterway network is one of the main transport corridors for merchant shipping. The Saimaa inland watercourse is a challenging operating environment due to shallow waters, narrowness of the fairways, fast currents as well as the sensitiveness of the environment. It is recognised that the heavy vessel traffic poses a risk of oil pollution. An oil spill incident in inland waters has a high potential for contaminating shorelines and affecting populated areas. Responding to such an incident involves several governmental and regional authorities, agencies and voluntary organisations. Inter-agency coordination is considered a key element in incident management. Several exercise types can be used to train multi-agency collaboration in joint response operations. This paper analyses the benefits of tabletop exercises in the strengthening of joint preparedness and contingency planning. Paper compares the outcomes of discussion-based exercises with operations-based drills and full-scale exercises. The analysis is based on four oil spill response tabletop exercises and five oil response drills conducted in Saimaa region in 2017–2018. Different types of exercises make it possible to focus on different aspects of the response operation. Operations-based exercises are useful in improving technical skills and testing procedures and the functioning of the equipment. Due to time restrictions, the equipment deployment drills usually focus on a specific function or a single task. Tabletop exercises can be used to assess contingency plans on a strategic level. Tabletop exercises offer an opportunity to clarify roles and responsibilities, discuss priorities and establish inter-agency agreements. The advantages of tabletop exercises include their flexibility in scenario-building, low-cost implementation and the possibility to study a longer time span in order to gain a more holistic view of the response operation.

Opis:
An analysis of energy plants from the point of view of their suitability for remediation of oil-contaminated territories was carried out. Plantations of Salix viminalis L., Helianthus tuberosus L. and Medicago sativa L. were planted with the purpose of remediation of the territory where active oil production is conducted. The prospect of using Salix viminalis and Helianthus tuberosus as effective restorers of technogenically-transformed environment quality was revealed. The limiting factors restricting the growth of Salix viminalis on degraded soils were established, involving dry air and insufficient soil moisture. Medicago sativa is sensitive to the level of soil contamination by pollutants and can act as a phytoindicator of the environmental quality of oil-contaminated ecosystems.

Opis:
Shiporigin operational discharges of oil mainly include the discharge of bilge water from motor rooms, fuel oil sludge and oily ballast water from fuel tanks. Also, various tankers can illegally discharge of tank-washing residues. Accidental discharges can appear when ship collide or come in distress at sea (e.g. engine breakdown, fire, explosion, pipeline breaks). There is necessity of continuous inspection of marine shipping routes, especially in environmentally sensitive areas (e.g. whole Baltic Sea). If protection against oil pollution is considered - the coastal nations of the North Sea are formed in the Bonn Agreement, whereas coastal nations of the Baltic Sea are formed in the HELCOM convention. Both organizations carrying out the international aerial surveillances and manage international oil-combat systems. Unfortunately, air surveillance can operate mainly in good weather, good visibility and in daylight. The surface of the whole world is observed independently on the time of day and weather by antennas of Synthetic Aperture Radars (SAR) of dozen military satellites with resolution of several meters. Some civil satellites equipped with SAR, supply every few days a set of signals which in ground-based centres are transformed to image of a define area of the sea surface. In these images, the shapes of places, which can be interpreted as polluted by an oil film, are shown. The system is introduced after EU directive and managed by European Maritime Safety Agency (EMSA). EMSA has developed the CleanSeaNet service - a satellite based monitoring system for marine oil spill detection. Advantages and limitations of the SAR-methods are discussed in this study. Physical, meteorological and hydrological as well as organizational conditions for effective use of this system are considered.
