Opis:
In the process of oil exploitation and transportation, large amounts of crude oil are often spilled, resulting in serious pollution of the marine environment. Forecasting oil spill reverse trajectories to determine the exact oil spill sources is crucial for taking proactive and effective emergency measures. In this study, the backward-in-time model (BTM) is proposed for identifying sources of oil spills in the East China Sea. The wind, current and random walk are three major factors in the simulation of oil spill sources. The wind drag coefficient varies along with the uncertainty of the wind field, and the random walk is sensitive to various traits of different regions, these factors are taken as constants in most of the state-of-the-art studies. In this paper, a self-adaptive modification mechanism for drift factors is proposed, which depends on a data set derived from the drifter buoys deployed over the East China Sea shelf. It can be well adapted to the regional characteristics of different sea areas. The correlation factor between predicted positions and actual locations of the drifters is used to estimate optimal coefficients of the BTM. A comparison between the BTM and the traditional method is also made in this study. The results presented in this paper indicate that our method can be used to predict the actual specific spillage locations.

Opis:
The exploration and utilization of petroleum are potential hazards to the environment. Successful determination of petroleum contamination in ground relies on accurate definition of the type, source and quantity of contaminant. For this purpose the Rock-Eval® pyrolysis was applied, which is a rapid quantitative (Bulk Rock method) and qualitative (fractional composition using Multi-Heating Rates method) technique. Results of Rock-Eval analysis of 13 samples of concrete and 2 samples of gravel taken from the different sites of the petrol station indicate the highest concentration of light hydrocarbons (gasoline and naphtha fractions), up to over 5% wt. in the direct proximity of petrol pumps. Similarly high contamination (almost 4%wt.), was found near fuel tanks. Here the highest contribution has lubricating oil fraction and the tankers providing fuels are probably the source of this pollution. In the gravel collected in the vicinity of the fuel tanks high concentration (over 5 wt.%) of non-pyrolyzable carbon (soot) was recorded, the source of which are probably diesel engines of fuel tankers supplying fuel.

Opis:
The paper presents the overall risk management state for the crude oil tanker fleet, evidenced by EMSA and other international marine organisations. Based on historical statistical data related to fleet size, accident reports, amount of oil spilled on the sea and the economic value of the crude oil transport business, the risk acceptance criteria are evaluated. The Formal Safety Assessment is further used for a systematic assessment of risk, where potential hazards are analysed with structured methods (HAZID) and represented in event trees. The paper studies three risks: PLL (potential loss of lives), PLC (potential loss of containment) and PLP (potential loss of property). A general approach is presented and discussed with a particular focus on the evolution of risk acceptance in recent decades and evaluations of risk F-N curves for different tanker sizes.

Opis:
Should an oil spill of tier III magnitude occur in the Northern Adriatic, there is a high probability that the oil will reach and pollute the surrounding coastline. Therefore, it is vital to conduct coastal vulnerability studies to develop priority plans and coastal vulnerability maps to help first responders protect the coastline. As there is no common contingency plan for oil spills in the Northern Adriatic, three countries, Italy, Slovenia, and Croatia, which share the area, decided to participate in the North Adriatic Incident Response System (NAMIRS) project. Part of the project was to conduct a coastal vulnerability study in the area. One of the three pillars for determining vulnerability, in addition to the ecological and geomorphological factors, is the socioeconomic aspect, which was studied as part of the research. As there are no clear scientific methods to determine the vulnerability of the socio‐economic factors, a survey was conducted where the participants gave their subjective opinion on its value. This was done through three workshops organised in each participating country, where professional stakeholders familiar with the state of socio‐economic activities assessed their vulnerability. The values obtained were combined with the assessments of the geomorphological and environmental factors and gathered in a coastal vulnerability layer, which was incorporated into a GIS as a standard coastal vulnerability map that will help first responders prioritise coastal protection. The research results will also be useful globally and not just in the area studied by NAMIRS, since the method used is readily applicable to any part of the world.

At present, monitoring of air pollution near industrial facilities is one of the most urgent tasks. Its implementation is a requirement of Article 42 of the Constitution of the Russian Federation and the basis for the ecological well-being of the population. This problem is especially critical for the production facilities located within residential areas or in close proximity to them. The scientific article presents the results of a monitoring study of the air pollution in a residential area exposed to the negative impact of the storage of primary oil refining waste. Within the frames of the scientific research, the analysis of the stock materials of the enterprise was conducted; field observation was performed on the territory of the considered enterprise and the construction of ecological cartographic models was carried out, reflecting the level of the air pollution in the territory under consideration. The study also carried out a literary review and presented a list of the main existing technologies for the utilization of oil sludge to improve the quality of the air in the region under consideration.

The paper presents some results of research on the fluorescence properties of petroleum oil-in-water emulsions. The research addresses the question of measuring and modelling light fields in an oil-polluted marine environment. The fluorescence of the emulsion manifests itself in the spectral range from 260 to over 400 nm and is much less intensive in the visible light region. Fluorescence is always weaker than the radiation scattered in an emulsion. The measurement and modelling of ultraviolet radiation scattering requires fluorescence to be taken into consideration, but in the visible spectral region this phenomenon is negligible.

Opis:
For many years, gender issues have continued to dominate discourses locally and globally. It is therefore heart-warming to note that women are providing leadership not only at home but in other spheres of life, be it economic, social or political. The exploration and exploitation of oil in the Niger Delta region has resulted in untold hardship, eco-trauma, bio-terrorism and the general neglect of the area. The debacle associated with oil exploration has affected the people and denied them their traditional occupations. Women are not left out and are confronted with new challenges of violence, health and political issues metted on them by the federal government of Nigeria in collaboration with multi-national oil companies, the army, navy and the police. Lives and properties are lost to gas flares, blow out from oil spillage, environmental pollution etc. Meanwhile, the federal government and multi-nationals grow fat at the expense of the poor. Oil capitalism has brought sorrow and doom to the region, as the Delta remains under-developed. Ojaide’s thematic preoccupation in The Activist is to throw more light on the plight of the Niger Delta people especially the women who face various forms of victimizations like rape, miscarriages, occupational disempowerment, pollution, lose of eyesight and other health hazards. This paper seeks to highlight the role of these women who refuse to be seen as docile and second class as well as their socio-political activism in reversing their predicament. Three theories inform the focus of the paper through it’s characters representation namely; eco-feminism, feminism and the Marxism theories as the women and the masses fought the oil workers and their cohorts to a halt to gain full control of the companies and become employers of labour in the once ravaged, impoverished environment by oil companies. The paper is based on library research.

Opis:
Public crude oil fields in Wonocolo sub-district were active from 1942 until now and have inadequately operated. The aims of this research were to measure the level of total petroleum hydrocarbon (TPH) pollution and their distribution in soil and surface water at the Wonocolo public crude oil fields. Twelve composite soil samples were collected from uncontaminated and contaminated sites of old well (OW), transportation line (T), and refinery area (R) at the depths of 0–30 cm, 30–60 cm, and 60–90 cm. The composite surface water sample was obtained from two points with different distances from the river side. TPH from soil and surface water samples were extracted using soxhlet and gravimetric method. Quantification of TPH was performed using Fourier Transform Infrared (FT-IR) Spectrometer. From the results of this study, it was concluded that soils and surface water are contaminated by TPH of 119.80–107,190 µg/g and 211,025.73 µg/L, respectively. TPH is clearly located in the upper of 0–30 cm depth at OW, T, and R sites (52,328.14–107,189.63 µg/g). These concentrations exceeded the soil quality standard of TPH and classified as category A for human hazard risk. The findings from this study show that there are considerable health risks which are potentially poisonous to humans in the local area. We recommend that remediation could be conducted using biological methods to reduce TPH pollution level.

Opis:
Współcześnie wpływ substancji ropopochodnych na środowisko naturalne, tj. gruntowo-wodne, jest niezwykle duży. Zanieczyszczenia węglowodorami ropopochodnymi w środowisku powodują ogromne skutki ekologiczne i są zwykle wprowadzane do ekosystemu antropogenicznie. W glebie węglowodory ropopochodne wpływają na jej właściwości fizyczne. Degradacja zależy od charakteru, składu, właściwości fizycznych i chemicznych. Degradacja obejmuje biotyczne i abiotyczne przemiany chemiczne. W pracy omówiono przebieg prac remediacyjnych na terenie zanieczyszczonym substancjami ropopochodnymi. Zastosowano technikę hybrydową remediacji gleby, która okazała się skuteczna. Początkowe zastosowanie utleniania chemicznego przyczyniło się do zmniejszenia frakcji ciężkiej zanieczyszczeń. Zastosowane kolejno autorskie traktowanie z wykorzystaniem czynników biologicznych, jak autochtoniczna mikroflora glebowa czy surfaktanty, pozwoliło na znaczące zmniejszenie zanieczyszczeń do poziomu nieprzekraczającego dopuszczalnej normy. Proponowana technika hybrydowa może być skutecznym narzędziem do remediacji gleb zanieczyszczonych substancjami ropopochodnymi.
The contemporary influence of petroleum substances on the natural environment, i.e. soil and water, is extremely large. Pollution of petroleum hydrocarbons in the environment causes enormous ecological effects and is usually introduced into the ecosystem anthropogenically. In soil, petroleum hydrocarbons affect the physical properties of the soil. The degradation depends on the nature, composition, physical and chemical properties. Degradation includes biotic and abiotic chemical transformations. The paper discusses the course of remediation works in the area contaminated with petroleum substances. The work uses the hybrid soil remediation technique, which turned out to be effective. The initial use of chemical oxidation reduced the heavy fraction of the pollutants. The successively applied proprietary treatment with the use of biological factors, such as autochthonous soil microflora or surfactants, allowed for a significant reduction of pollutants, not exceeding the permissible standard. The proposed hybrid technique may be an effective tool for the remediation of soils contaminated with oil derivatives.

Opis:
Development of industry and trade in the last few decades caused a huge increase in the pollution of the world's oceans. Substantial contributors to marine pollution come with the rivers from land-based sources including the by products of industry, run-off from agriculture activities such as biocides as well as effluents from urban areas. Moreover, a significant amount of marine pollution is caused by shipping and maritime activities. The operation of ship plants gives a real possibility for engine oils and fuels to reach the marine environment. Discharge waters contain a certain amount of petroleum derivatives in the form of dispersed droplets (oil-in-water emulsion). The presence of oil emulsion cause measurable changes in the optical properties of seawater. It is conceptually possible to detect these changes using a standard radiance or irradiance reflectance meter. Hence, a set of radiative transfer simulation has been carried out. This paper presents a computed photon trace simulation based on the Monte Carlo code, applied to the marine environment. The results are presented as reflectance spectra for the models of Baltic Sea and ocean water both pure and polluted by oil emulsion. It is shown that even small amounts of petroleum pollution raise the values of irradiance reflectance and cause a spectral shift by certain conditions. A possibility for remote evaluation of oil pollution is discussed as well as the perspective for improving the interpretation of shipboard and offshore light field analyses.
