It's hot in summer. You should pay attention not to put a lot of things in the car. You always hear that you don't put mineral water in the car. You regret being exposed to the sun and causing cancer. Is this true?
Will mineral water have harmful substances after exposure to the sun?
In order to verify whether mineral water will precipitate harmful substances after exposure? Someone once did an experiment. Ten brands of bottles of mineral water were purchased. Each brand purchased two bottles on the same production date, and then divided into two groups. One group was exposed under the front windshield, and the other group was placed in a cool indoor place for one week.
During the whole process, in order to understand the temperature in the vehicle, the experimenter will measure the temperature in the vehicle every 2 hours. In this week's test, most of them are sunny days, of which the maximum temperature in the car is about 70 ℃ in 4 days and about 50 ℃ in 3 days. Basically completely in line with the actual vehicle situation.
One week later, take out two groups of mineral water and entrust a professional comprehensive testing center for comparative testing. The total number of 18 plasticizers and colonies in water were strictly detected. The experimental results showed that 18 carcinogenic plasticizers such as dioctyl phthalate (DEHP) were not detected in bottled water samples whether exposed to sunlight or not.
Can I drink it?
Through the above experiments, we know that the mineral water in the car is safe after exposure, and no harmful substances will be detected. However, it is recommended that the car owner drink less exposed mineral water as much as possible. Apart from that, the taste of mineral water after high-temperature exposure is very poor.
After Kaifeng, if the water is not drunk in time in a short time, it is easy to breed various bacteria and deteriorate, which will have an adverse impact on the body. If it is not drunk, it is best to take it away when getting off the bus.
So, what things can't be put in the car for a long time? Are these harmful to human body?
1, vehicle perfume
The quality of the perfume used on the market is uneven in quality. In many cases, the aroma of vehicle perfume is nothing more than a "trick". When you are immersed in aroma, you may be suffering from chronic poisoning. Moreover, the inferior vehicle perfume can easily leak or even explode under high temperature.
2. CD
The main raw material of optical disc is polycarbonate, which contains a large amount of bisphenol A, which is a toxic chemical raw material. When the temperature in the car is above 60 ℃, this substance will easily diffuse into the air, causing air pollution in the car. Excessive intake will lead to chronic poisoning, especially damage to the nervous system and blood circulation system, and will also have an adverse impact on children's intellectual development.
3. Drugs
Drugs, like mineral water, will weaken or change their properties under high temperature. Therefore, please try not to put some commonly used drugs in the car.
4. Lighter
Many people who like smoking will habitually put their lighters on the dashboard after lighting cigarettes. As everyone knows, there will be great safety worries in summer! Because, under the sunlight, the liquid butane in the lighter will expand, increasing the internal pressure of the lighter. In addition, the bumps and collisions during driving can easily cause the lighter to explode.
5. Reading glasses and magnifying glasses
Remember the experiment in primary school science class? Aim a magnifying glass at the paper in the sun and it won't take long for the paper to burn. This is because when the light passes through the magnifying glass, refraction occurs, and all the light will gather in the middle. When countless strong lights gather at the same point, they will produce strong heat, resulting in the combustion of combustibles.
6. Carbonated beverage
Bottled carbonated drinks will also produce harmful substances after high temperature, but in addition, there is another reason, that is, carbonated drinks contain carbon dioxide, which is easy to expand at high temperature and cause package rupture.
7. Battery
The battery is easy to age under the action of high temperature, and the poor battery will have unstable shape and even explode. There are also batteries in mobile phones and digital cameras. When the temperature in the car is high, the battery heat can not be emitted in time. Gathering in a certain place will aging the circuit boards of these small household appliances.
8. Power bank
Why doesn't the power bank let you take more on the plane? Because it's equivalent to a small bomb! The power bank is composed of lithium batteries, which are in danger of explosion in case of high temperature exposure.
