The Impact

Total petroleum hydrocarbons (TPHs) and Polycyclic aromatic hydrocarbons (PAHs) are priority pollutants which are known to be associated with petroleum products. They are released into the marine environment via accidental spillage, exploration and transportation. The present study aims to assess the impact of petroleum and gas extraction activities on the pollution of coastal marine sediment of the western coastline of Qatar. Sixty-six surface sediment samples were collected along the western coastal area. The concentration of organic hydrocarbons (TPHs and PAHs) were determined using GC-FID and GC-MS, respectively. Sediment characteristics including pH, temperature, TOC and particle size were also measured. The results indicated low concentrations of TPH (<0.001-0.246 μg/g dry weight sediment) and PAHs (<0.001-0.044 μg/g dry weight sediment). The concentrations for both organic pollutants were lower compared to the previous studies done within Qatar and in the Arabian Gulf and also indicated below the available permissible limit set by the Ministry of Municipality and Environment of Qatar and other sediment quality guidelines (SQGs) used worldwide (NOAA).

Total Petroleum Hydrocarbons (TPHs) and Polycyclic Aromatic Hydrocarbons (PAHs) are priority pollutants, which are known to be associated with petroleum products. They are released into the marine environment via accidental spillage, exploration and transportation. The present study aims to investigate the type, origin and weathering of petroleum in the coastal marine sediment of the western coastline of Qatar. Sixty-six surface sediment samples were collected along the western coastal area. The concentrations of organic hydrocarbons (TPHs and PAHs) were determined using GC-FID and GC-MS, respectively. Sediment characteristics including pH, temperature, TOC and particle size were also measured. The results indicated low concentrations of TPH (<0.001-0.246 µg/g dry weight sediment) and PAHs (<0.001-0.044 µg/g dry weight sediment). The concentrations for both organic pollutants were lower compared to the previous studies done within Qatar and in the Arabian Gulf and also indicated below the available permissible limit set by the Ministry of Municipality and Environment of Qatar and other Sediment Quality Guidelines (SQGs) used worldwide (NOAA). Pollution concentration profile is site specific where concentrations are high within the proximity of the source and derived from both direct inputs of petrogenic and pyrogenic contribution.

The Impact

The aim of the welfare state, in accordance with the Constitution of Ukraine is to ensure conditions for the growth of welfare of citizens. One of the major components in the well-being of civilized societies is to ensure that citizens and businesses the necessary energy. Energy development is the basis for enhancing the social and economic living standards of the population and competitiveness. The key to this goal should be a reliable, economically viable and environmentally sound needs of the population and the economy of energy products. It is important to identify the critical factors is a threat to the energy security of the national economy. The state of the energy sector of Ukraine is negatively affected by continued dependence on imports of Russian natural gas, petroleum products and fuel for power plants. Today such dependence on primary energy, including coal, has become a leverage to Ukraine on the part of the neighboring state. The loss of the fuel and energy complex, and areas for future development of hydrocarbon resources as a result of the annexation of the Crimea and the military operations in the east of the country, as well as the destruction of the oil and gas infrastructure in the Donetsk and Luhansk regions, yielded additional new factors which significantly weakened the energy security of the country. Given the instability of strategic task for Ukraine, it is vital to achieve the highest possible level to ensure the economy’s own oil and gas resources, which, to a certain extent, will contribute to energy independence and savings of foreign exchange reserves of the country, as well as infrastructure development in the industry, tax revenues, creation of additional jobs.

The Impact

ABSTRACT Over the last century there has been a significant increase in the number and size of oil spills to the marine environment due to the global proliferation of oil and gas extraction as well as the number of tankers and other maritime transport infrastructure associated with increased production. Efforts have traditionally been focussed on containment and deflection of oil rather than responding to wildlife. The present study examines total oiled wildlife effort in response to maritime spills for 286 recorded globally. Between 1910 and 1961 there was an average of 1.23 ± 0.43 incidents per year, spilling an average of 114,062 ± 352,512 tonnes of oil per year. These averages increased to 3.83 ± 2.65 events with 123,277 ± 166,735 tonnes of oil spilt per year from 1962 to 1990, and again, from 1991 to 2012 to 6.50 ± 5.17 events with 164,299 ± 290,655 tonnes of oil spilt per year. Offshore platform and tanker spills have accounted for 37% and 27% of this total, respectively. Of the 104 recorded instances where wildlife interactions occurred (40%), spill volume was not related to the total number of animals caught, oiled or pre-emptively; however, it was related to the number of carcasses collected. A lack of planning for Oiled Wildlife Response (OWR) was identified as a contributing factor exacerbating the impact of a spill on wildlife and for resourcing a response. Inadequacies within operator and government contingency planning, to prepare for and sustain a wildlife response for extended periods, can be overcome by using a mobilisation model that integrates wildlife carer networks, government regulatory agencies and operator resourcing via an independent coordinating organisation consisting of a small group of personnel highly experienced and trained in maritime operations and marine science with access to a network of persons with experience in responding to wildlife and their handling, treatment and rehabilitation.

The paper presents the data on the situation of the oil and gas complex of the Saratov region. It is shown that the Saratov region is a promising region for hydrocarbon production and one of the leaders in the Volga Federal district, since 85 % of the territory is occupied by oil and gas-promising lands. The structure of the oil and gas complex and the dynamics of production of hydrocarbons in the region are presented in the article. The paper describes the indicators of the oil and gas complex, background accident risks that determine environmental pollution. The results of monitoring the pollution of the territory of the largest in Europe Stepnovsky gas storage facility, created on the basis of the Stepnovsky oil and gas processing enterprise, which operated from 1953 to 1973, are given. It is proved that during the production and storage of hydrocarbons at this enterprise, there was a strong pollution of the soil with oil and petroleum products, so their content reaches 1527 mg/kg of soil in the upper half-meter layer, and 2060 mg/kg of soil in the second half-meter. The content of plumbum and copper in the soil is 3.3 and 2.3 times higher above the background values for dark chestnut soils. The accumulation of a significant amount of unsaturated hydrocarbons (C1-C10) in the subsurface air from 25.97 mg/m3 to 38.17 mg/m3 is proved. It is shown that the extraction and storage of hydrocarbons at the Stepnovsky enterprise did not lead to a deterioration of the sanitary and microbiological condition of the studied soil.

Metal Monitoring

A case of arsenic contamination has recently been detected in the Lami coastal environment during the course of a heavy metal monitoring in Fiji's coastal environment. Twenty two surficial sediment samples were sampled during the 2008–2009 period, extracted for arsenic and analysed using graphite furnace atomic absorption spectrometry. Two sites within the Lami estuary recorded the highest As levels of 334 and 282 mg kg–1 as dry weight in sediments samples, which has greatly exceeded the local and global average background concentrations. Chemical fractionation studies using a standard sequential protocol showed that As is mostly associated with residual (strong acid extractable) phase of the sediments, however significant amounts of As were also detected in bioavailable (exchangeable, water and acid soluble), reducible and oxidisable fractions. Comparison with standard sediment quality guidelines (SQGs) indicate that As levels are likely to be highly toxic to biota, hence further ecotoxicological studies are warranted to evaluate possible environmental effects on the aquatic environment.

Abstract This study aimed at examining the impact of oil pollution from artisanal oil refineries on the Oturuba river ecosystem using active river bottom sediment. Specific objectives included to determine the level of hydrocarbons and trace metals (Pb, Cd, Zn, Cu, Ni, V and Mg) in the sediments and to relate this with general ecosystem health. The study found elevated concentrations of both hydrocarbons and heavy metals in the range above most sediment quality guidelines exceeding the respective Threshold Effects Level and Probable Effects. Level guideline values and occurring at levels where impairment to biological communities is certain an d where toxicity levels can lead to negative impacts on benthic animals or infaunal communities. Heavy metal geochemical accumulation index and potential ecological risk analysis also returned anomalously high concentrations in the range of very highly polluted sediment environments with very high ecological risk indices, thereby ranking the Oturuba Creek as one of the most polluted coastal river systems in the world.

Aim. This study was an attempt by the authors to identify the impact of oil production in the Caspian Sea on the quality of waters surrounding oil and gas-production platforms.Material and Methods. In 2018, by order of the Committee for Forestry and Wildlife of the Ministry of Agriculture of the Republic of Kazakhstan, Kazekoproekt carried out comprehensive marine research to assess the state of biological resources in the eastern part of the Caspian Sea. All studies were carried out according to standard methods accepted in international practice. Samples were collected in summer (July-August) 2018 and autumn (September) 2018.Results. An analysis of the materials of environmental studies carried out in the water area of the eastern part of the Caspian Sea in 2018 established the absence of biogenic concentrations in sea water in excess of the standard indicators. It was found that in the waters surrounding several stations in summer and autumn, concentrations of oil products were exceeded. The concentrations of pesticides in the waters of the northern Caspian Sea recorded in 2018 were not detected.Conclusion. It was found that in the eastern part of the Caspian Sea in 2018 there was no concentration of biogenic elements in sea water above the standard indicators. Of the heavy metals, an excess of maximum permissible concentrations was found only at one station - of copper in the summer over 159 sq. m and in the autumn over 121 sq. m. Of particular concern is the fact that at several stations in summer and autumn excessive concentrations of petroleum products were recorded. The concentrations of pesticides in the waters of the northern Caspian Sea recorded in 2018 were not detected.

AbstractThe impact of oil governance on the extraction path of non-renewable resources is theoretically ambiguous. By employing field-level data in the South East Asia region, we utilize a change in the institutional design of oil governance in Indonesia to determine its impact on oil and gas extraction paths. From the empirical results, we infer that the move to create a separate regulatory agency and make the national oil company a purely business entity led to a reduction in the extraction path of oil, the size of which varies for different sizes of resource stock. This finding reiterates the importance of strengthening ownership rights for non-renewable resources to avoid over-extraction and facilitate more sustainable economic outcomes.
