Your Gas Stove May Be Leaking Benzene Into Your Kitchen —Even When It ’ s Off
The U.S. goes through a lot of natural gas, consuming more than 30 trillion cubic feet of it last year, according to the U.S. Energy Information Administration—about 15% of which is burned by home appliances. On top of climate concerns—natural gas may be less carbon polluting than coal, but the methane released during production is a powerful greenhouse gas in its own right—there is a growing awareness of the risk this gas poses to our health.
According to a new study published today in the journal Environmental Science and Technology, not only the atmosphere, but your kitchen may be a victim of contamina...

Remote sensing reveals unprecedented sublethal impacts of a 40-year-old oil spill on mangroves
Environ Pollut. 2023 May 24:121859. doi: 10.1016/j.envpol.2023.121859. Online ahead of print.ABSTRACTOil spills cause long-lasting mangrove loss, threatening their conservation and ecosystem services worldwide. Oil spills impact mangrove forests at various spatial and temporal scales. Yet, their long-term sublethal effects on trees remain poorly documented. Here, we explore these effects based on one of the largest oil spills ever recorded, the Baixada Santista pipeline leak, which hit the mangroves of the Brazilian southeastern coast in 1983. Historical, Landsat-derived normalized difference vegetation index (NDVI) maps o...

The U.S. Scientist At the Heart of COVID-19 Lab Leak Conspiracies Is Still Trying to Save the World From the Next Pandemic
Ralph Baric stepped onto the auditorium stage at the University of North Carolina, Chapel Hill, and looked out at the sparse audience that had come to hear him speak. On the large projector screen hanging behind him, the following words appeared: How Bad the Next Pandemic Could Be, What Might It Look Like, and Will We be Ready. The date was May 29, 2018.
“Well, I have to admit I’m a little worried about giving this talk,” Baric said. “The reason is being labelled a harbinger of doom.” The screen shifted, and images of the four horsemen of the apocalypse—Death, Famine, War, and Plague&mda...

The Massive Oil Plume Beneath Pearl Harbor Isn't New, But It Is Shocking
Pearl Harbor was once known as Oahu's "bread basket" because it was such an important fishing area, teeming with ocean life. But since the construction of the iconic U.S. military base, the pristine harbor has been marred by environmental disaster. The 12,600 acres of land and water that make up the Pearl Harbor Naval Complex were added to the Environmental Protection Agency's National Priority List of hazardous waste sites in 1992. This list identified the area as a Superfund site, or one that could harm local people or ecosystems due to hazardous waste. In 1998, the health department had issued an ad...

Sensors, Vol. 21, Pages 2351: A Deep-Learning Framework for the Detection of Oil Spills from SAR Data
al
Ayman El-Baz
Oil leaks onto water surfaces from big tankers, ships, and pipeline cracks cause considerable damage and harm to the marine environment. Synthetic Aperture Radar (SAR) images provide an approximate representation for target scenes, including sea and land surfaces, ships, oil spills, and look-alikes. Detection and segmentation of oil spills from SAR images are crucial to aid in leak cleanups and protecting the environment. This paper introduces a two-stage deep-learning framework for the identification of oil spill occurrences based on a highly unbalanced dataset. The first stage classifies patches bas...

Are oil spills enhancing outbreaks of red tides in the Chinese coastal waters from 1973 to 2017?
Environ Sci Pollut Res Int. 2021 May 31. doi: 10.1007/s11356-021-14549-3. Online ahead of print.ABSTRACTBetween 1973 and 2017, evidences of red tide outbreaks and oil spill accidents in the Chinese coastal waters were collected. Statistical analysis and multiple regression models were used to determine the relationship between the red tide and the oil spill. Major findings reveal that (1) the frequency of red tides positively correlates to the number of oil spills and the volume of oil spilled as well; (2) the higher percentage of small spills (< 7 tonnes) are more likely to enhance the outbreaks of red tides; (3) both ...

Sensors, Vol. 23, Pages 4298: Development and Analysis of a Distributed Leak Detection and Localisation System for Crude Oil Pipelines
Kouyi
Crude oil leakages and spills (OLS) isare some of the problems attributed to pipeline failures in the oil and gas industry&rsquo;s midstream sector. Consequently, they are monitored via several leakage detectiondetection and localisation techniques (LDTs) comprising classical methods and, recently, Internet of Things (IoT)-based systems via wireless sensor networks (WSNs). Although the latter techniques are proven to be more efficient, they are susceptible to other types of failures such as high false alarms or single point of failure (SPOF) due to their centralised implementations. Therefore, in this wo...

The Significance of One Email: How Prepared Are We for the Next Major Oil Spill?
In September 2010, I was a scientist working at the Unified Command in New Orleans, the official operating center responding to the Deepwater Horizon oil spill. With the fifth anniversary of the spill today, everyone is asking me: Are we more prepared for the next spill? Perhaps the best answer to that question arrived a few weeks ago in a single email.
The email was from one of the lead federal officials responsible for responding to oil spills after an inquiry from one of my academic colleagues. It was sent the day after the April 1st explosion of a Mexican oil-processing rig in the Gulf of Mexico that killed four peopl...

Using fault tree analysis in the Al-Ahmadi town gas leak incidents
Publication date: November 2015 Source:Safety Science, Volume 79 Author(s): Khaled Alkhaledi , Sami Alrushaid , Jasem Almansouri , Ahmed Alrashed The gas leak incidents that occurred in Al-Ahmadi, Kuwait, were considered to be unprecedented phenomena worldwide. Three gas explosions occurred between January 2010 and November 2010: two occurred at different houses that were connected to the Kuwait Oil Company natural gas network in north Al-Ahmadi, and one occurred at a house in south Al-Ahmadi that was not connected to the network. These explosion incidents triggered an immediate investigation. The fault tree analysis was...

Application of solidifiers for oil spill containment: A review.
Abstract
The need for new and/or improvement of existing oil spill remediation measures has increased substantially amidst growing public concern with the increased transportation of unconventional crudes, such as diluted bitumen products. Solidifiers may be a very good spill response measure to contain and mitigate the effects of oil discharge incidents, as these interact with the oil to limit hydrocarbon release into air and water, prevent it from adhering onto sediment and debris, and could allow for oil recovery and reuse. Solidifiers change the physical state of the spilled oil from liquid to a coherent mass ...

Evaluation of the diagnostic ratios of adamantanes for identifying seriously weathered spilled oils from simulated experiment and actual oil spills
AbstractThe composition and physical properties of spilled oil have great changes during the seriously weathering process. It brings great difficulties to the source identification of oil spill. So the stable and trustworthy diagnostic ratios (DRs) for accurate identification of severely weathered spilled oils are very important. The explosion of Sinopec pipeline happened on November 22, 2013 at Qingdao, China. Local beaches at Jiaozhou Bay were polluted by spilled oils. We have collected original spilled oil samples from an area free from human interference near the oil leakage point after the accident. Synchronized with ...
