Lessons from a professional learning community: Navigating tensions while moving between theory and practice in teaching chemistry for social justice

open access: yesScience Education, Volume 108, Issue 3, Page 734-761, May 2024.
Abstract Maintaining a commitment to social justice teaching can be especially challenging when navigating the bureaucratic systems and ever‐spiraling responsibilities of the education system. To better understand how social‐justice‐oriented educators navigate these tensions, this paper uses qualitative methods to investigate the social justice ...

Evaluation of Toxicity Levels and Cytotoxicity Mechanisms of Corexit 9500 [PDF]

open access: yes, 2013
The 2010 British Petroleum (BP) oil spill in the Gulf of Mexico has raised many ecological and health concerns. BP predominately used Corexit9500A to disperse crude oil in the Gulf of Mexico to prevent shoreline contamination.

Interactions between zooplankton and crude oil: toxic effects and bioaccumulation of polycyclic aromatic hydrocarbons. [PDF]

open access: yesPLoS ONE, 2013
We conducted ship-, shore- and laboratory-based crude oil exposure experiments to investigate (1) the effects of crude oil (Louisiana light sweet oil) on survival and bioaccumulation of polycyclic aromatic hydrocarbons (PAHs) in mesozooplankton ...

Acute effects of COREXIT® EC9500A on cardiovascular function

open access: yesThe FASEB Journal, 2011
The goal of these studies was to characterize cardiovascular responses after an acute inhalation exposure to COREXIT® EC9500A, the oil dispersant used in the Deepwater Horizon oil spill response. Male Sprague Dawley rats underwent a single 5 h exposure to COREXIT® EC9500A (N= 5 exposures, average exposure level 27.12 mg/m

Neurotoxicity Following Acute Inhalation Exposure to the Oil Dispersant COREXIT EC9500A [PDF]

open access: yesJournal of Toxicology and Environmental Health, Part A, 2011
Consequent to the 2010 Deepwater Horizon oil spill in the Gulf of Mexico, there is an emergent concern about the short- and long-term adverse health effects of exposure to crude oil, weathered-oil products, and oil dispersants among the workforce employed to contain and clean up the spill. Oil dispersants typically comprise of a mixture of solvents and

Effects of a crude oil and an oil dispersant (Corexit 9527) on populations of the littleneck clam (Protothaca staminea)

open access: yes, 1982
Field and laboratory experiments were carried out to investigate the effects of Alberta crude oil and an oil dispersant (Corexit 9527) on the larval settlement, survival, siphon activities and behaviour of the littleneck clam (Protothaca staminea ...

Effects of Exposure of Pink Shrimp, Farfantepenaeus duorarum, Larvae to Macondo Canyon 252 Crude Oil and the Corexit Dispersant

open access: yesJournal of Marine Science and Engineering, 2016
The release of oil into the Gulf of Mexico (GOM) during the Deepwater Horizon event coincided with the white and pink shrimp spawning season. To determine the potential impact on shrimp larvae a series of static acute (24–96 h) toxicity studies with ...

Fish Waste Based Lipopeptide Production and the Potential Application as a Bio-Dispersant for Oil Spill Control

open access: yesFrontiers in Bioengineering and Biotechnology, 2020
There is a growing acceptance worldwide for the application of dispersants as a marine oil spill response strategy. The development of more effective dispersants with less toxicity and higher biodegradability would be a step forward in improving public ...

Lethal and sublethal effects of oil, chemical dispersant, and dispersed oil on the ctenophore Mnemiopsis leidyi

open access: yesAquatic Biology, 2015
We established the lethal levels for water-accommodated fractions of Corexit® 9500A chemical dispersant, crude oil (WAF), and dispersed crude oil (CEWAF) for the ctenophore Mnemiopsis leidyi at both 15 and 23°C.

Effect of Corexit 9500A on Mississippi Canyon crude oil weathering patterns using artificial and natural seawater

open access: yesHeliyon, 2017
During the 2010 Deepwater Horizon oil well blowout in the Northern Gulf of Mexico (GoM), the application of 6.97 million litres of chemical dispersants was used at the well-head and on the sea surface to promote oil degradation and weathering of the ...
