The concept of Ct was first proposed by Fritz Haber and is sometimes referred to as Haber's law, which assumes that exposure to 1 minute of 100 mg/m 3 is equivalent to 10 minutes of 10 mg/m 3 (1 × 100 = 100, as does 10 × 10 = 100).
For example, in the 1930s Widmark measured alcohol and blood by mass, and thus reported his concentrations in units of g/kg or mg/g, weight alcohol per weight blood. Blood is denser than water and 1 mL of blood has a mass of approximately 1.055 grams, thus a mass-volume BAC of 1 g/L corresponds to a mass-mass BAC of 0.948 mg/g.
This is considered a pharmaceutical disadvantage due to the high risk of causing drug-induced toxicity by increasing the absorption and serum concentration above the therapeutic window of the drug. The best way to prevent this interaction is by avoiding the co-ingestion of both substances or using specific controlled-release formulations that ...
Low-alcohol beers (<0.5) are considered in some countries such as Iran as permitted (or "halal" under Muslim vocabulary) despite alcohol being banned. [7] However, the level of alcohol-free beers is typically the lowest commercially sold 0.05. [citation needed]
The lethal dose for most adult humans is estimated at 5 to 10 grams, equivalent to 32 to 64 mg elemental fluoride per kg of body weight. [ 17 ] [ 18 ] [ 19 ] Ingestion of fluoride can produce gastrointestinal discomfort at doses as low as 0.2 mg/kg, 20 times lower than lethal doses. [ 20 ]
Referring to a common salt of fluoride, sodium fluoride (NaF), the lethal dose for most adult humans is estimated at 5 to 10 g (which is equivalent to 32 to 64 mg elemental fluoride/kg body weight). [ 2 ] [ 3 ] [ 4 ] Ingestion of fluoride can produce gastrointestinal discomfort at doses at least 15 to 20 times lower (0.2–0.3 mg/kg or 10 to 15 ...
Greece: 0.05% (BrAC 0.25 mg/L), [81] reduced to 0.02% (BrAC 0.10 mg/L) for unlicensed or new drivers who have held a license for less than two years, motorcycle and professional drivers. [82] Above 0.11% (BrAC 0.60 mg/L) it's considered a flagrant misdemeanour punishable with up to two years of imprisonment and a hefty fine in the court plus ...
properly diluted chlorine preparations (f.e. Dakin's solution, 0.5% sodium or potassium hypochlorite solution, pH-adjusted to pH 7–8, or 0.5–1% solution of sodium benzenesulfochloramide (chloramine B)), some; iodine preparations, such as iodopovidone in various galenics (ointment, solutions, wound plasters), in the past also Lugol's solution,
