Affecting children's physical and intellectual development, how terrible is the formaldehyde problem in the car?

A few days ago, in the live broadcast barrage, a fan asked the big ice cube: "The smell of the new car is very large, and I feel dizzy after smelling it for a long time, can a 3-month-old child sit?" "There must be many friends who have such troubles, giving birth to a child, adding a second child, to change a new car, what are the dangers of the smell of the new car to children?

First of all, the odor of new cars mainly comes from plastic parts such as center consoles, roof materials, thermal insulation materials and other decorative materials, such as carpets, seat packaging, etc. These materials contain a variety of harmful gases, such as: formaldehyde, benzene, toluene, xylene, TVOC, etc.

Due to the incomplete development of children's organs, if they are injured by formaldehyde and TVOC in the car at this time, it will affect their health: 1. Induce children's blood diseases; 2. Increase the incidence of childhood asthma; 3. Lead poisoning in children; 4. Make children's intelligence greatly reduced.

Even adults, often inhaling a small amount of formaldehyde, can also cause chronic poisoning, mucosal hyperemia, skin irritation, allergic dermatitis keratosis and fragility, nail bed finger pain, long-term inhalation of pregnant women may also lead to newborn baby malformation.

Those who often read our articles know that in order to more accurately detect the amount of formaldehyde released in the air in the car, we use "pump-suction sampling" and "phenol reagent spectrophotometry" to test the air in the car. This test method is the formaldehyde test method currently used by formal testing institutions.

Test method: the test vehicle is in a natural environment, open the doors and windows for complete ventilation; Subsequently, a silicone hose is fixed near the driver's headrest to simulate the breathing position of the person; Close the doors and windows, park the vehicle in a constant temperature of 23±1°C and let it stand for 16 hours; Use a sampler to suck out 10 liters of air from a hose pump and react with phenolic reagents; Drop the chromogen into the phenolic reagent and let stand for 15 min; The sample after color development was detected using the aldehyde formaldehyde detector and the results were obtained.

The table below is a ranking of the ten cars with the lowest formaldehyde content in the list of the number of formaldehyde measurements in the air in the car we have tested, and the value is a ranking from high to low, which can give a reference to small partners who are ready to buy a car and change cars.

The amount of formaldehyde released from the ceiling, seats, floors, etc. also needs to be measured using professional instruments. The following two charts show the ten models with the lowest measured values of formaldehyde in the head/seat and floor.

In addition to formaldehyde in the car, TVOC is also an important toxic and harmful gas, which is one of the main reasons for the strong taste in the car. TVOC refers to the general term for all organic gaseous substances in space, such as benzenes, alkanes, aromatics, olefins... These organisms can cause harm to human health.

Test method: the test vehicle is in a natural environment, open the doors and windows for complete ventilation; Subsequently, a silicone hose is fixed near the driver's headrest to simulate the breathing position of the person; Close the doors and windows, park the vehicle in a constant temperature of 23±1°C and let it stand for 16 hours; Using the MP181 TVOC detector, the air in the car is sucked from the hose pump until the value is stabilized, and the final result is obtained. After 16 hours of closure in a constant temperature environment of 23±1°C, the measured values of formaldehyde and TVOC emissions in the air in the car were measured. The figure below shows the 10 models with the lowest value in terms of interior air TVOC measurement value.

Today is the annual children's holiday. The reason why I talk to you about formaldehyde in the car on such a day is because no matter from the physical or intellectual development of children, the harm of environmental pollution in the car to children cannot be ignored.
