Widmark developed two other equations (one for men and one for women) where he was able to estimate the uncertainty (one standard deviation) in his computed value for N. His uncertainty equations are (1): men S N = /0.015625N2 + 0.050176 (N (0.68C t W/0.8z))2. women S N = /0.01N2 + 0.021904 (N (0.55C t W/0.8z))2.

The derivation of Widmark's uncertainty estimate is also presented, showing that he considered only rho and beta to be uncertain. Widmark estimates for the number of drinks should include a 2CV estimate of approximately 25% while the blood alcohol concentration estimate should include a 2CV estimate of approximately 42%. Some evaluations were made on the Widmark method is designed for determination of blood ethanol concentration. A reagent of potassium dichromate-sulfuric acid mixture was found potent within 3 weeks after preparation when kept air-tight in hard glass ware without exposure to light, and 0.01 N sodium thiosulphate reagent was potent within 2 weeks under similar conditions.

Widmark formula: where: A = dose of ethanol in grams r = Widmark’s rho, a constant A = r ρ (C t + (ß t) C =t BAC at time “t” in hours. ß = Widmark’s beta, a constant a zero order elim. rate constant = 0.015%/hr. Ratio of amt. of alcohol in the body to that in the blood. Now called Vd, the volume of distribution

Now called Vd, the volume of distribution 2000-01-27 Blood alcohol content can be estimated by a method developed by Swedish professor Erik Widmark [] in the 1920s: = / (×) − × where: A is the mass of alcohol consumed.; r is the ratio of body water to total weight. It varies between individuals but averages about 0.68 for men and 0.55 for women, since women tend to a higher percentage of fat. The BACs measured at 2 h and 5 h post-drinking were used to estimate the amount of alcohol each subject had consumed according to the method proposed by Widmark. The mean differences (estimated-actual) and the +/- 95% limits of agreement were -0.72 g (+/- 12), and 2.2 (+/- 15), for the 2 h and 5 h BAC values, respectively.

Widmark Factor can be estimated for any subject. Zuba and Piekoszewsk2 commented that the Widmark procedure was the most popular method of making alcohol calculations. In 1981, Watson et al.3 suggested an alternative formulation, changing the terminology to bring greater clarity and make the dilution equation easier to understand.

1.1. Deriving Widmark’s equation From Widmark’s ability to measure alcohol in blood, he desired a mathematical expression allowing him to determine the total amount of alcohol absorbed and distributed within the Although I just published a blog on June 11th, today is a special day in the lives of forensic toxicologists and warrants a memorial entry. Erik Matteo Prochet (EMP) Widmark, the famous pioneer researcher in forensic alcohol toxicology, was born 125 years ago on June 13th 1889 in Halsingborg, Sweden.
