Что означает HCHO?
Формальдегид HCHO. Формальдегид – это бесцветный газ с острым специфичным запахом, хорошо растворяющийся в спирте и воде. Он известен и под такими традиционными названиями, как муравьиный альдегид или метаналь. Формальдегид широко применяется в различных отраслях промышленности.
Что такое формальдегид и чем он опасен?
Формальдегид(Е 240, от лат. formica – «муравей»), муравьиный альдегид, официально признан канцерогеном, так как доказано, что использование формальдегида связано с повышенным риском развития онкологических заболеваний. Это бесцветный газ, обладающий резким запахом, хорошо растворимый в воде и спирте. Он очень токсичен.
Что вызывает HCHO?
Берегите детей, формальдегид может вызывать раздражение слизистых оболочек, органов дыхания и вызывать аллергические реакции. Показатель в анализаторе воздуха – концентрация формальдегида (HCHO), измеряется в микрограммах на квадратный метр.
How can I check the air quality in my home?
Measuring Your Indoor Air Quality
If you want to measure the indoor air quality of your home or business, then you will need a special tool called a VOC sensor. This tool will measure the concentration of VOCs in the air. It can pick up everything from ketones to formaldehyde throughout your home.
Can you test your own air quality?
You can monitor your indoor air quality using an air quality monitor. It will check your air for particulate matter like dust and allergens, as well as chemical pollutants like volatile organic compounds. An air quality monitor will check humidity and temperature levels too.
Do cheap air quality monitors work?
The South Coast AQMD tested the accuracy of 55 of the most popular PM2. 5 air quality monitors on the market. The sensors ranged in price from $70 to $7800. As seen in the chart below, there was almost zero relationship between price and accuracy.
Which air quality monitor is most accurate?
The PurpleAir PA-II was the most accurate air quality sensors tested, with a 95% accuracy. It also was the only monitor in the top 6 that is waterproof and can be used outdoors. The popular Elitech Temtop LKC-1000S+ and Atmotube Pro was not too far behind with a tested 91% and 88% accuracy.
Is there an app to check air quality?
EPA’s AirNow mobile app provides a simple interface for quickly checking current and forecast air quality information for planning daily activities and protecting your health.
How do I find air pollution in my area?
Check air pollution level in your area with these apps
- Air Quality | Air Visual.
- Air Quality Index BreezoMeter.
- Air Quality by Plume Labs.
- Air Quality: Real time AQI.
How do you check air quality outside?
For current air quality, visit AirNow.gov. During fire events, use the Fire and Smoke map.
What is the normal air pollution level?
| AQI Category, Pollutants and Health Breakpoints | ||
|---|---|---|
| AQI Category (Range) | PM10 24-hr | PM2.5 24-hr |
| Good (0-50) | 0-50 | 0-30 |
| Satisfactory (51-100) | 51-100 | 31-60 |
| Moderately polluted (101-200) | 101-250 | 61-90 |

What is the most accurate AQI website?
Airnow.gov is the gold standard when it comes to knowing the precise measurement of pm 2.5.
Can AQI be predicted?
AQI Forecasts
They use a number of tools – including weather forecast models, satellite images, air monitoring data, and computer models that estimate how pollution travels on the air.
Is IQ Air accurate?
Therefore, according to the calculation below, IQAir AirVisual Pro sensors have low accuracy compared to FEM GRIMM. mass concentration from Unit 4VW9, Unit WLL6, and Unit X44P was 100%. measurement variations were observed among the three IQAir AirVisual Pro units.
Why is AQI different on different sites?
Update frequency: It is possible that different sources update at different times. This can cause different locations to show different data – some current, some outdated. Update time is listed under the air quality reading on the AirVisual app – and can also be found on the US EPA (AirNow) website.
What are the best outdoor air quality monitors?

- Best Wearable:
Are VOC sensors accurate?
Because of the relative nature of the sensor output, the VOC sensor cannot define an accuracy tolerance. The VOC sensor was designed to monitor common indoor air quality contaminants only. There are several gases that will affect the sensor reading but are not typical indoor contaminants.
Are VOC monitors accurate?
Yet that isn’t the case. In our research, we’ve found that most monitors of this class aren’t that great, with many giving unreliable (if not false) readings, especially of volatile organic compounds (VOCs) such as chemical vapors and formaldehyde. Some monitors can accurately measure fine particulates, typically PM2.
What does AQI 103 mean?
AQI values at and below 100 are generally considered to be satisfactory. When AQI values are above 100, air quality is considered to be unhealthy, at first for members of populations at greatest risk of a health effect, then for the entire population as AQI values get higher (greater than 150).
What does AQI 60 mean?
The higher the AQI value, the greater the level of air pollution and the greater the health concern. For example, an AQI value of 50 or below represents good air quality, while an AQI value over 300 represents hazardous air quality.
What are the six levels of air quality?
These six pollutants are carbon monoxide, lead, nitrogen oxides, ground-level ozone, particle pollution (often referred to as particulate matter), and sulfur oxides.
Is a AQI of 200 bad?
Everyone may begin to experience health effects when AQI values are between 151 and 200. Members of sensitive groups may experience more serious health effects. Very Unhealthy. AQI values between 201 and 300 trigger a health alert, meaning everyone may experience more serious health effects.
What AQI is safe for running?
A rating below 50 is perfectly safe to run in .
Running in an AQI of between 51-100 for most people who are healthy is fine to run in, however over time may become unhealthy. This is especially true for sensitive individuals.
What happens if air quality is over 500?
Exceeding the 500 scale indicates the situation is terrible. At 500, maximum damage is done so there is no point going beyond that. It’s a situation similar to the US Environment Protection Agency’s (EPA) hazardous level. Its recommended that people remain indoors but indoor air quality is also impacted.”
