What are theelectronic cigarettes, liquid smoke and atomized smoke we smoke?
How much formaldehyde is there?
Everyone has always been most concerned about the composition of the smoke oil and the main components of the atomized smoke. First, summarize it for everyone, and then explain it to you one item at a time:
Knowledge points +1
The main components of the smoke liquid are propylene glycol, glycerin, and spices. The main components of the smoke are the direct atomization of 4 types of substances;
RELX cigarette oilthe main components
With atomized smoke
Test and measure with the highest standards
In the flue gas, because it will produce some trace substances after atomization, RELX chose to use theFrench AFNORelectronic cigarettesstandard "XPD90-300-3"the mostthat the limit of heavy metals in the flue gas of the RELX relx refilledindustry in the beginning, to change the atomized smoke of RELX. The harmful components in the flue gas such as a variety of aldehydes and ketones, 11 kinds of heavy metals, acetyls, alcohols, a variety of tobacco-specific nitrosamines, VOCs and other types of compounds, as well as%degree transmission stability were tested.
For the e-liquid, we chose the third-party testing agencyPenny Testing Groupto conduct 9 standard tests on theRELX refilled atomized e-liquid with reference to the national analysis standards of thedomestic food industry.
The test results showthat the limit of heavy metals in the flue gas of the RELX relx refilledatomized smoke is in compliance with the relevant requirements and standards of the EU electronic cigarette.
Ask yourself with the highest standards you can find.
The carbonyl compounds contained formaldehyde in the aldehyde and ketone detection in the table above.
Toxicity needs to be discussed in conjunction with dosage. Let me share a few small knowledge about formaldehyde:
Knowledge points +2
In our lives, it is difficult to avoid exposure to formaldehyde;
Knowledge points +3
There is indeed a small amount of "formaldehyde" in the atomized smoke, but the toxicity of formaldehyde needs to be discussed in conjunction with the dose. The formaldehyde content of each RELX atomized smoke is only equivalent to each cubic meter required in the "Health Standards for Formaldehyde in Room Air" 0.06% of formaldehyde limit;
Knowledge points +4
If the formaldehyde content reaches the so-called 10 + mg / m³ (mg / m3), you will feel that the acidic stimulating gas in the air is completely unbearable.
"Formaldehyde" in life
Where do they all exist?
After reading some references, formaldehyde, which sounds terrible, appears in many places in our lives:
The following data references:
Zhai Shumiao, Xu Xiaoyan, Formaldehyde exposure and health effects [J]; Environment and Health Journal; 1994-05
How does formaldehyde come
Formaldehyde content after smoke oil is atomized into smoke
In "Hygienic Standards for Formaldehyde in Room Air",0.06% of the required formaldehyde limit per cubic meter
In 2018, atRELXwe conducted a comprehensive and detailed inspection of atomized gas with the help of TCT general test.
TCT general test detection:
Testing institutions approved by China National Accreditation Service for Conformity Assessment (CNAS)
Relx TCT general test report
As shown in the report,
the content of formaldehyde inRELXatomized gas is:
The cumulative total of 100 mouths is 4.6 μg (micrograms)
Equivalent to 0.046μg (microgram) per bite
Which is 0.000046mg (mg)
1mg (mg) = 1000μg (microgram)
This value will move up and down due to the change of the taste of the smoke pod
100 formaldehyde intake of RELX
Judging from this document, without taking into account the influence of other factors, the intake of formaldehyde from200RELX(about 1 pack of cigarettes per day)is the daily respiratory intake from the outdoor atmosphere Of two-fifths of theexogenous formaldehyde.
The maximum allowable concentration of formaldehyde in the room air specified in the national standard"Hygienic Standard for Formaldehyde in Room Air" is 0.08mg / m³ (mg / m3)
After comparison, the formaldehyde content of each RELX atomized smoke is only equivalent to 0.06% of the formaldehyde limit per cubic meter required by the "Health Standards for Formaldehyde in Room Air";
When the formaldehyde content exceeds 10 + mg / m³,
Human beings are already unbearable.
The olfactory threshold for formaldehyde is usually 0.06 ~ 0.07mg / m³.
If it exceeds this concentration, the most intuitive feeling is that you will smell the pungent sour taste.
Then, if the formaldehyde content reaches the so-called 10 + mg / m³ (mg / m3), you will feel that the acidic stimulating gas in the air is completely unbearable.
Since the establishment of Yue Ke, we have been in-depth cooperation with experts, scholars and scientific research institutions in related health fields.
