To find out the blood alcohol content, a unit of ppm is used. Everyone has heard about this, but not everyone knows what this indicator means. For example, not everyone will answer the question of 2 ppm of alcohol - how much alcohol is in the blood. Is such a dose dangerous? Let us consider in more detail what is covered by this term, how much one unit per mille includes, and what the Law says about when it’s dangerous to drive and what indicator. How much beer is allowed and is it permissible at all if you are going on a trip?
Promille - what is it?
The unit per mille allows you to determine what dose of alcohol is present in the blood. A thousandth of the alcohol shows the ethanol concentration in the blood. The indicator also allows you to identify how much alcohol was drunk.
Dealing with this unit is easy enough. Many people are used to operating parts of an integer - half, quarter, third, tithing. Often very small parts are required, so a percentage appeared, this is a hundredth of the total. In reports and assessments of activity, this unit appears quite often. How to figure out, 2 ppm of alcohol - how much alcohol is in the blood?
This indicator (ppm) is an even smaller unit than a percentage - a thousandth of a substance. Thus, if you connect the percentage and the ppm, then it is worth noting that in one percent - ten ppm. Per mille is a tenth of a percent.
Under laboratory conditions, the alcohol content is determined using a unit of ppm (‰), because the percentage (%) is too large a value. The ratio is measured in hundredths, tenths of a ppm, so, for example, an indicator of 2 ppm is a lot.
It is important to consider that the body is individual for everyone, the perception of alcohol varies between women and men. Equally, the effect of toxins occurs on the same principle. In the female body, ppm accumulate faster than in men.
How to count yourself
The calculation in ppm, in principle, does not differ from the calculations in percentage, but for the full picture does not prevent to figure it out. As we have already mentioned, the ppm is indicated by the sign, reminiscent of the percentage%. They should not be confused. Designating the level of alcohol, the following ratios apply:
- 1/1000 = 1 ‰ is 0.1%;
- 1 = 1000 ‰ = 100% - monofractional composition without any impurities;
- 0.4 = 400 ‰ = 40%;
- 0,00024 = 0.24 ‰ this is 0.024%.
How to calculate 2 ppm of alcohol - how much alcohol? Focusing on the above relations, it is not difficult to do this: 2 ‰ is 0.2% = 1/2000.
The difference between percent and ppm is purely nominal. After drinking alcohol, in half an hour there comes a peak in its content. Using calculations, knowing the per mille, you can find the following values:
- The alcohol content after some time.
- The volume of alcohol taken.
- How much time is needed for alcohol to leave the body.
To calculate these parameters, you will also need data:
- Age, weight, gender of a person.
- % fluid in the body.
- The amount of alcohol consumed initially.
Calculation Example
The mass of the man is 82 kg. Drunk 500 ml of vodka 40%.
In men, water by weight is approximately 70%, which means 57.5 kg for this example. The density of undiluted ethanol is 0.79. Therefore, 500 x 0.4 we get 200 ml, we translate into grams 200 x 0.79 158 leaves. The content of pure alcohol is 158 g - 10% we get 142.4.
So, the ethanol concentration of the drink is 142.4: 57.2 = 2.5 ppm.
Now it’s clear that 2 ppm of alcohol is how much alcohol. The rate is very high.
An example proves that the calculation of ppm is available to everyone. To calculate does not require a lot of data, the formula is simple. Note that the values given are conditional, but not absolute. After all, the use of alcohol occurs in different ways, gradually. Ethanol in the body is processed over a period of time. It is also necessary to make a discount on the age, physiological state of a person.
Blood alcohol table
The most popular question for drivers concerns how much alcohol is contained in the permissible 0.16 ppm. Firstly, the Law speaks about the content in mg of alcohol when exhaled per liter of air, this is not a concentration in the blood. Secondly, this value is measured with a breathalyzer, the error of the device corresponds to the given value. Consequently, even for an absolutely sober person, he can lie in this limit.
For a complete picture, below is a table of blood alcohol at various doses.
How alcohol affects behavior
Depending on the concentration of alcohol in the blood, several levels of intoxication are released. At the first stage - mild intoxication, then - moderate severity, the last stage is the most severe, can lead to coma and even death. Each person has a specific lethal dose per kg weight.
Recall that in percentage - 10 ppm. The characteristic level for each stage is given in%:
- Up to 0.03 - intoxication is not determined.
- From 0.03 to 0.06 - weak intoxication.
- From 0.06 to 0.16 - the initial stage or mild intoxication.
- From 0.16 to 0.26 - moderate or moderate intoxication.
- From 0.26 to 0.3 - the third degree is a strong intoxication.
- From 0.3 to 0.6 is an extreme severe degree in which coma and even death are likely.
- From 0.6 to 0.65 is a lethal alcohol dose.
So, a person’s condition can be determined in fractions of the percentage of alcohol in the blood.
Consequences of driving
Everyone knows that you need to drive in a sober state. But still, what is the border, what concentration of alcohol in the blood is dangerous? Consider how human behavior changes with an increase in ppm.
- 0.2 - 0.51 ‰. Already at such a dose, the perception of moving light sources is erroneous. Slow assessment of the situation on the road. In this case, there is a desire to speed up the movement. In this condition, the driver exceeds speed, but accuracy and caution suffer. The car is dangerous to others. The driver does not observe the distance and interval.
- 0.51 - 0.81 ‰. The driver does not feel the distance to the object, the balance is disturbed, errors occur in driving. Distinct failure to assess the situation. Inadequately perceived light signals, distance.
- 0.81 - 1.21 ‰. Relaxing effect on the body. The angle of view decreases, the driver has a weak reaction to what is happening around, the actions are incorrect and weak, the concentration of attention disappears. The driver is extremely dangerous to others.
- 1.21 - 2.4 ‰. With such intoxication, a person loses a clear consciousness. To the limit, vision is disturbed, the orientation is completely distorted. Hence it is clear that intoxication of 2 ppm is extremely dangerous, and a person simply can’t drive.
Lethal dose
What dose of alcohol can be called deadly? A definite answer does not exist, each organism has its own abilities. One can make an assumption only on the basis of average values and indicators. These numbers can only indicate how much alcohol is permissible and what needs to be avoided.
Many studies indicate that 5-6 ppm is a lethal alcohol dose. Extreme intoxication begins already at 2 ppm. Few people understand these units, many consider the dose in liters. The question arises: 2 ppm of alcohol - how much is vodka? We make approximate calculations.
In 0.5 l of vodka contains 200 ml of pure alcohol - this is equivalent to 2.5 ppm. Consequently, the lethal dose will be three bottles = 1.5 liters. But death can only occur if this quantity has been drunk over the shortest time. For example, one hour. If you take into account a long time, a snack, then strong intoxication will come, but not death.
With beer and wine, the situation is different. Alcohol is contained significantly less. The lethal dose is much larger. In addition, the body has a protective reflex for intoxication - vomiting, while most of the alcohol is removed.
The lethal outcome is also affected by the weight, age of the person, his susceptibility to alcohol. The situation of the disease of the liver, kidneys, stomach, as well as the quality of the alcohol worsens.
Permissible alcohol rate
The norms of readings per mille in 2017 are significantly different from 2010-2013, when only zero mille was envisaged. No amount of alcoholic vapor was allowed in expired air. The law has been revised for a number of reasons. There are products that do not contain alcohol, but on a special device show small units per mille. These include:
- kvass;
- chocolate;
- nonalcoholic beer;
- yogurt;
- yogurt;
- warm juice;
- oranges
- a sandwich with brown bread and sausage;
- overripe banana;
- mouth freshener;
- certain medications;
- cigarettes.
Small doses of alcohol contained in these products disappear after a short period of time. For this reason, the legislation canceled zero ppm. Previously, a driver who used a glass of kvass or kefir could lose his rights for up to two years. This fact caused a lot of controversy, and in 2013 a law was passed. With the onset of its action, the allowable rate of alcohol began to be 0.16 ppm in expired pairs, which corresponds to 0.35 in the blood. An amendment to this law has been introduced in the Rules of the road.
Methods of punishment
If the number of ppm exceeds the permissible norm, then the driver bears the following penalties:
- Initial detection: a fine of 30 thousand is imposed, and the driver is also deprived of his rights for a period of 1.5-2 years.
- Secondary violation: the fine will be 50 thousand, the driver is deprived of his rights for 3 years.
If a deprived person gets behind the wheel, he faces up to 15 days.
Do not trust your own transport to anyone, especially a person in a strong alcoholic intoxication. When transferring control in this case, the owner of the car is also fined in the amount of 30 thousand and he is deprived of his driver’s license for up to 2 years.
In the near future, it is expected that a law will be adopted that will further tighten the requirements for drunk drivers. Be carefull!
