Analytical developments for oil spill fingerprinting
Publication date: February 2015 Source:Trends in Environmental Analytical Chemistry, Volume 5 Author(s): Josep M Bayona , Carmen Domínguez , Joan Albaigés Oil fingerprinting is widely used to defensibly determine the source of an oil spill by matching compositional parameters of both the spilled oil and candidate sources. The unambiguous identification of oil sources and their characteristics are of paramount importance for assessing the fate and environmental damage of the spill, provide an appropriate spill response and also for assigning responsibilities and liabilities. The most widely used methodologies in Europe ...

False localizing sign of cervico-thoracic CSF leak in spontaneous intracranial hypotension
Conclusions: Cervico-thoracic extravasation of dye on myelography does not necessarily indicate the site of the CSF leak. Treatment directed at this site should not be expected to have a high probability of sustained improvement of symptoms.

Impact of the quantity of intradiscal cement leak on the progression of intervertebral disc degeneration.
Conclusions Our findings indicate that the quantity of cement leaking into the disc space significantly influences the rate of progression of disc degeneration. PMID: 28853606 [PubMed - in process]

3D graphene-based nanostructured materials as sorbents for cleaning oil spills and for the removal of dyes and miscellaneous pollutants present in water.
This article reviews the research undertaken to control oil spillage using three-dimensional (3D) graphene-based materials. The use of these materials for removal of dyes and miscellaneous environmental pollutants from water is explored and the application of various multifunctional 3D oil sorbents synthesized by surface modification technique is presented. The future prospects and limitations of these materials as sorbents are also discussed. PMID: 29098585 [PubMed - as supplied by publisher]

Modelling biodegradation of crude oil components at low temperatures.
Abstract For oil spilled at sea, the main weathering processes are evaporation, emulsification, photo-oxidation, dispersion and biodegradation. Of these, only biodegradation may completely remove hydrocarbons from the environment in the long term, as the other processes only serve to transform and dilute the oil components. As petroleum development is moving north, the probability of Arctic oil spills increases. Hence, it is imperative to develop methods for comprehensive risk assessment of oil spills in cold and ice-covered waters. Accurate biodegradation rates are an essential part of this, as they are required ...

IJERPH, Vol. 18, Pages 2226: Bioremediation of Total Petroleum Hydrocarbons (TPH) by Bioaugmentation and Biostimulation in Water with Floating Oil Spill Containment Booms as Bioreactor Basin
Sharma A crude oil spill is a common issue during offshore oil drilling, transport and transfer to onshore. Second, the production of petroleum refinery effluent is known to cause pollution due to its toxic effluent discharge. Sea habitats and onshore soil biota are affected by total petroleum hydrocarbons (TPH) as a pollutant in their natural environment. Crude oil pollution in seawater, estuaries and beaches requires an efficient process of cleaning. To remove crude oil pollutants from seawater, various physicochemical and biological treatment methods have been applied worldwide. A biological treatment method using b...

Haematological, renal, and hepatic function changes among Rayong oil spill clean-up workers: a longitudinal study
CONCLUSION: Results of this study show the differences between baseline and follow-up haematological, renal, and hepatic indices and trends of these indices. The long-term changes in the indices in this study show worsening renal functions after oil spill and possibility of cardiovascular effects. These findings contribute to expanding knowledge on the long-term health effects of oil spills.PMID:35094133 | DOI:10.1007/s00420-022-01834-y

Comparison between oil spill images and look-alikes: an evaluation of SAR-derived observations of the 2019 oil spill incident along Brazilian waters
An Acad Bras Cienc. 2022 Jun 17;94(suppl 2):e20211207. doi: 10.1590/0001-3765202220211207. eCollection 2022.ABSTRACTThree SAR-derived observations of dark surface patches along the Northeastern Brazilian coastline by the end of 2019 were misreported in the Brazilian media as oil spill-related. Unfortunately, these observations were misled by false positives or look-alikes. Therefore, this paper aims to technically evaluate these look-alike classes by analyzing image attributes found to be helpful to the identification of ocean targets, including oil spills, rain cells, biofilms, and low wind conditions. We use image augmen...

Sensors, Vol. 23, Pages 3226: Pipeline Leakage Detection Using Acoustic Emission and Machine Learning Algorithms
This article proposes a machine learning-based platform for leakage detection for various pinhole-sized leaks using the AE sensor channel information. Statistical measures, such as kurtosis, skewness, mean value, mean square, root mean square (RMS), peak value, standard deviation, entropy, and frequency spectrum features, were extracted from the AE signal as features to train the machine learning models. An adaptive threshold-based sliding window approach was used to retain the properties of both bursts and continuous-type emissions. First, we collected three AE sensor datasets and extracted 11 time domain and 14 frequency...
