Blood alcohol content (BAC), also called blood alcohol concentration or blood alcohol level, is a measurement of alcohol intoxication used for legal or medical purposes. [1] BAC is expressed as mass of alcohol per volume of blood. In US and many international publications, BAC levels are written as a percentage such as 0.08%, i.e. there is 0.8 ...
The blood alcohol content (BAC) for legal operation of a vehicle is typically measured as a percentage of a unit volume of blood. This percentage ranges from 0.00% in Romania and the United Arab Emirates; to 0.05% in Australia, South Africa, Germany, Scotland, and New Zealand (0.00% for underage individuals); to 0.08% in England and Wales , the ...
England and Wales and Northern Ireland: 80 mg/100 mL (~0.08% BAC) alcohol in blood, 35 μg/100 mL alcohol in breath or 107 mg/100 mL alcohol in urine. [131] [132] Scotland: 50 mg/100 mL (~0.05% BAC) alcohol in blood or 22 μg/100 mL alcohol in breath (legislation became effective from 5 December 2014) [133]
Earlier studies found mean elimination rates of 15 mg/dL per hour for men and 18 mg/dL per hour for women, [6] [4] but Jones found 0.148 g/L/h and 0.156 g/L/h respectively. Although the difference between sexes is statistically significant, it is small compared to the overall uncertainty, so Jones recommends using the value 0.15 for the mean ...
μg/dL Blood ethanol content: Limit for drunk driving: 0, [135] 0.2, [135] 0.8 [135] ... mg/dL Lactate (Venous) 4.5 [23] 19.8 [23] mg/dL: 0.5 [180] 2.2 [180] mmol/L ...
Death from ethanol consumption is possible when blood alcohol levels reach 0.4%. A blood level of 0.5% or more is commonly fatal. The oral median lethal dose (LD 50) of ethanol in rats is 5,628 mg/kg. Directly translated to human beings, this would mean that if a person who weighs 70 kg (150 lb) drank a 500 mL (17 US fl oz) glass of pure ...
Drunk driving is the act of operating a motor vehicle with the operator's ability to do so impaired as a result of alcohol consumption, or with a blood alcohol level in excess of the legal limit. [1] For drivers 21 years or older, driving with a blood alcohol concentration (BAC) of 0.08% or higher is illegal.
I could see how someone might get the impression that .08 grams per deciliter of blood was the same volume as .08 mg/L of breath, so I changed the values to reflect the same volume for each unit of measure mentioned. (i.e., 0.10 g/dL of blood alcohol is the same BAC as 0.476 mg/L of breath alcohol and the same as 0.10 g/210L of breath alcohol).
