Early products in the line included Corexit 7664 [4] and Corexit 8666. Corexit 9527 is one of the first modern concentrate dispersants and has been in use since the mid 1970s. Corexit 9500 was designed to replace Corexit 9527. In 2002, Corexit 9527 and Corexit 9500 were the only two chemical dispersants stockpiled in large quantities in the U.S ...
The primary dispersant used were Corexit 9527 and 9500, which were controversial due to toxicity. In 2012, a study found that Corexit made the oil up to 52 times more toxic than oil alone, [12] and that the dispersant's emulsifying effect makes oil droplets more bio-available to plankton. [13]
Toxicologist and marine biologist Riki Ott has also spoken on the toxicity of the spilled crude oil and of the dispersant Corexit, "The dispersants used in BP's draconian experiment contain solvents, such as petroleum distillates and 2-butoxyethanol. Solvents dissolve oil, grease, and rubber.
The BP (BP) oil spill may be over, but controversy over the company's use of toxic oil dispersants in the Gulf of Mexico is still going strong. Although BP allegedly stopped using the chemicals ...
It is a key element of glucose testing, including home blood glucose monitoring (HBGM) performed by people with diabetes mellitus or hypoglycemia. A small drop of blood, obtained from slightly piercing a fingertip with a lancet , is placed on a disposable test strip that the meter reads and uses to calculate the blood glucose level.
Prediabetes, often considered the step before diabetes, is when you have higher than usual blood glucose (blood sugar) levels. Your levels aren’t high enough to be classified as type 2 diabetes.
Blood glucose monitoring is the use of a glucose meter for testing the concentration of glucose in the blood . Particularly important in diabetes management , a blood glucose test is typically performed by piercing the skin (typically, via fingerstick ) to draw blood, then applying the blood to a chemically active disposable 'test-strip'.
The continuous glucose monitoring system uses a sensor, a reader and an app to help people with diabetes check their blood sugar without having to draw drops of blood from their fingers.
