Levels of phosphatidylethanols in blood are used as markers of previous alcohol consumption. [ 5 ] [ 6 ] An increase of alcohol intake by ~20 g ethanol/day will raise the PEth 16:0/18:1 concentration by ~0.10 μmol/L, and vice versa if the alcohol consumption has decreased.
[121] [122] It is less accurate for BAC levels below 0.2 g/L (alcohol is not eliminated as quickly as predicted) and consumption with food (overestimating the peak BAC and time to return to zero). [ 123 ] [ 93 ]
Helicity is a pseudo-scalar quantity: it changes sign under change from a right-handed to a left-handed frame of reference; it can be considered as a measure of the handedness (or chirality) of the flow. Helicity is one of the four known integral invariants of the Euler equations; the other three are energy, momentum and angular momentum.
Binge drinking is defined as the amount of alcohol it takes to raise a person’s blood-alcohol concentration level to 0.08, the legal definition of being intoxicated in most states.
Acceptable daily intake or ADI is a measure of the amount of a specific substance (originally applied for a food additive, later also for a residue of a veterinary drug or pesticide) in food or drinking water that can be ingested (orally) daily over a lifetime without an appreciable health risk.

Tolerable daily intake (TDI) refers to the daily amount of a chemical contaminant that has been assessed safe for human being exposure on long-term basis (usually whole lifetime). [1] TDI specifically occurs to chemicals that humans are exposed to unintentionally or as a contaminant, [ 1 ] where acceptable daily intake refers to chemicals that ...
Recommends an alcohol consumption level of zero grams. 10 g "The Health Council of the Netherlands included a guideline for alcohol consumption in the Dutch dietary guidelines 2015 (DDG-2015), which is as follows: ‘Don’t drink alcohol or no more than one glass daily’." "In the Netherlands, one regular glass of an alcoholic beverage ...
The absorption rate constant K a is a value used in pharmacokinetics to describe the rate at which a drug enters into the system. It is expressed in units of time −1. [1] The K a is related to the absorption half-life (t 1/2a) per the following equation: K a = ln(2) / t 1/2a. [1] K a values can typically only be found in research articles. [2]
