	HSRC : Blood Alcohol Concentration (BAC)
		Typically this measurement is converted to a percentage such as 0.10%, which indicates that one-tenth of a percent of a person's blood is alcohol.
		Because alcohol in the blood travels directly to the brain, cognitive functioning is affected, resulting in increased risk of many kinds of injuries.
		In North Carolina it is illegal to drive with a BAC of 0.08% or higher.

	Blood Alcohol Concentration
		In studies impairment is first seen at blood alcohol concentrations of 0.02 percent which shows that one does not have to be intoxicated to demonstrate impairment.
		BAC is most commonly linked with drunk driving and is important in determining the role alcohol could have played in accidents, violence and crimes.
		Alcohol is absorbed more slowly into the blood stream when food is present in the stomach, so the BAC rises more slowly.

		Alcohol is absorbed from all parts of the gastrointestinal tract largely by simple diffusion into the blood.
		Absorbed alcohol is rapidly carried throughout the body in the blood and once absorption of alcohol is complete an equilibrium occurs such that blood at all points in the system contains approximately the same concentration of alcohol.
		Blood alcohol concentration depends on the amount of alcohol consumed and the rate at which the user's body metabolizes alcohol.

	You Drink and Drive. You Lose.
		Blood alcohol concentration (BAC) is the amount of alcohol in an individual’s body, measured by the weight of the alcohol in a volume of blood.
		BAC can also be determined by drawing blood and measuring the amount of alcohol in the blood itself.
		Blood alcohol concentration is directly correlated with the degree of impairment an individual displays when driving after drinking.

	Absorption and elimination of alcohol
		The change in BAC with time may be described graphically as a "blood alcohol curve," where the absorption phase is represented by a rising line and the elimination phase by a falling line.
		After alcohol is absorbed into the bloodstream of a given individual, it is distributed throughout all body fluids and tissues according to the water content of those fluids or tissues.
		Blood analysis is a direct method for the determination of a blood alcohol level and urine analysis is an indirect method.

	Blood alcohol content Summary
		When countries outside Scandinavia enacted legal limits of ethanol in the blood of motorists, the concentrations were defined in units of mass of ethanol per unit volume; whether it was grams, milligrams, or micrograms of ethanol in a volume of milliliters, deciliters, or liters seems chosen arbitrarily.
		BAC is expressed as the weight of alcohol in a fixed volume of blood, for example, grams per liter.
		The measurement of alcohol concentration in the breath is converted into a measurement of alcohol concentration in the blood.

		In states of extreme intoxication, vomiting is likely to occur, possibly accompanied by incontinence, poor respiration, a fall in blood pressure, and in cases of severe alcohol poisoning, coma and death.
		A hangover is due partly to poisoning by alcohol and other components of the drink, and partly to the body's reaction to withdrawal from alcohol.
		Fetal Alcohol Syndrome may result from a pregnant woman's drinking alcohol; this condition causes facial abnormalities in the child, as well as growth retardation and brain damage, which often is manifested by intellectual difficulties or behavioral problems.

	BLOOD ALCOHOL CONCENTRATION (BAC)
		BAC.35%: This blood alcohol concentration is similar to the physical effects of surgical anesthesia.
		Scientists use the term "lethal dose" (LD) to describe the blood alcohol concentration that produces death from alcohol poisoning in half the population.
		Since studies of lethal dosage cannot be empirically tested in the laboratory, scientists estimate the LD for alcohol from post-mortem cases in which alcohol poisoning was the primary cause of death.

	Blood/Breath Alcohol Concentration (BAC) Calculator
		Blood/Breath Alcohol Concentration (BAC) is the amount of alcohol in the bloodstream or on one's breath.
		BAC is expressed as the weight of ethanol, measured in grams, in 100 milliliters of blood, or 210 liters of breath.
		The public usually associates BAC with "drunk driving." But it's more accurate to refer to "alcohol-impaired" driving because you do not have to be "drunk" to be impaired in your ability to safely drive a car.

	Alcohol Testing Methodologies
		Blood Alcohol Concentration (BAC) is considered to be the standard for measuring the degree to which an individual is impaired by alcohol.
		During this exchange, alcohol in the blood vaporizes and is carried out of the lungs in the exhaled breath.
		Saliva testers are treated with an enzyme Alcohol Oxidize, which responds to alcohol in proportion to the concentration of alcohol in a mixed saliva sample placed on it.

	Blood alcohol content - Wikipedia, the free encyclopedia
		Breath alcohol testing further assumes that the test is post-absorptive - that is, that the absorption of alcohol in the subject's body is complete [1].
		In an increasing number of states, laws have been enacted to facilitate this speculative task: the BAC at the time of driving is legally presumed to be the same as when later tested [5].
		While a mathematical BAC estimation is not as accurate as a breathalyzer, it can be useful for calculating a BAC level that is not currently testable, or a level that may be present in the future.

	Carleton College: Wellness Center: Blood Alcohol Concentration (BAC)
		For instance, having a BAC of 0.10 percent means that a person has 1 part alcohol per 1,000 parts blood in the body.
		The BAC rises more rapidly in those who drink on an empty stomach, because there is no food in which to dilute the alcohol.
		Women reach higher BAC s faster because they have less water in their bodies and more adipose tissue (fat), which is not easily penetrated by alcohol.

	Zero Tolerance Law
		If you are stopped by a police officer for having consumed alcohol and the officer deems that you are younger than 21 and appear to have consumed alcohol, you will be temporarily detained for the purpose of taking a breathalyzer test to determine your blood alcohol level (BAC), usually at the police station.
		If your BAC is.02% or more, but not more than.07%, you will be charged with the traffic offense of "driving after having consumed alcohol." You will then be provided with a notice to appear for a hearing before an administrative law judge of the Department of Motor Vehicles.
		While being charged with driving after consuming alcohol is considered a serious violation of the law, it is not designated as a crime and you cannot go to jail for violating this law.

	0.08% BAC Limit and Administrative License Suspension Laws
		California laws lowering the legal definition of DUI impairment to 0.08% BAC and requiring the immediate license suspension of persons violating that law have proven to be effective in reducing the incidence of alcohol-involved accidents, according to a recent California Department of Motor Vehicles' Research and Development Branch publication.
		In 1990, the 0.08% blood alcohol concentration (BAC) limit and administrative license suspension laws were implemented in California and were expected to have a large potential for reducing the incidence of drunk driving.
		Any impact of the new laws would be expected to be confined to accidents involving alcohol; therefore, we evaluated changes in the patterns of four categories of alcohol-related or nighttime fatal or injury accidents across three levels of accident severity which are likely to involve alcohol.

	New York State Blood Alcohol Concentration Breath Test Breathalyzer DWI (Site not responding. Last check: 2007-10-19)
		Breath testing, as currently used, is a very inaccurate method for measuring BAC, Even if the breath testing instrument is working perfectly, physiological variables prevent early reasonable accuracy....Breath testing for alcohol using a single test method, should not be used for scientific, medical or legal purposes where accuracy is important.
		The more alcohol present in the chamber (i.e,, the higher the percentage of alcohol in the breath sample), the more light is absorbed.
		In theory, then, determining the alcohol concentration of the sample is simply a matter of measuring the amount of light that reaches a receptor at the other end of the chamber; the more light, the lower the alcohol content in the breath.
