"Do you still use this kind of plastic bottle? It is toxic and carcinogenic, throw it away as soon as possible!" Xiaohu received a new push on his mobile phone, and he opened this article out of curiosity, which focused on the dangers of plastic bottles:
"Mineral water bottles should be thrown away after drinking, recycling can cause cancer!"
"Bottled seasonings with mineral water can precipitate heavy metals and release toxic substances, which can be harmful to health if used for a long time. ”
...
Looking at the mineral water bottle in his hand, Xiao Hu fell into deep thought: Is it really that terrible?
Plastic products are highly popular nowadays, and we can see plastic products anytime and anywhere in our lives, such as mineral water, beverages, soy milk and milk tea in plastic bottles, meals and various foods in plastic lunch boxes.
Due to the traditional virtues of waste utilization and thrift, many people will Xi recycling these plastic products. For example, use beverage bottles to store various spices, use plastic lunch boxes as storage boxes to store various foods, and so on.
These behaviors seem to be economical and environmentally friendly, but in fact, there are great potential health risks, and even the risk of causing cancer.
Plastic products are used in this way, which is toxic and harmful and carcinogenic!
Whether it's a beverage bottle, a disposable lunch box, or other plastic products, we can see some signs on it, and different logos represent different meanings.
If there are two arrows pointing horizontally to the opposite side, the plastic product is "reusable":
The following triangle made of arrows should be more familiar to you, many people mistakenly think that this is a sign of reuse, but in fact it is a sign of "recyclable":
Under normal circumstances, there will be a number from 1 to 7 in this triangle, and different numbers represent different resin raw materials, among which our most common No. 1, that is, polyethylene terephthalate, commonly known as PET material. Most of the mineral water bottles, beverage bottles and disposable lunch boxes we mentioned above are made of this material.
As long as this material is used normally in accordance with the regulations, there is no harm to human health, but if it is used like the following types, there are certain health risks.
(1) Hold high-temperature liquids
When we used to be children, we always used to use mineral water bottles for hot water. This generation of children, because the current beverage bottles are designed to be relatively high, so they are used to fill hot water.
As everyone knows, PET is not resistant to high temperatures, and can only hold food or hot water below 70 °C, once the temperature exceeds this temperature, the plastic bottle will deform and migrate harmful substances that are harmful to human health.
In addition, some people like to take bottled cooking oil, and most of them are still placed next to the stove, which is also dangerous. Because long-term high temperatures will also exacerbate the migration and diffusion of harmful substances in plastic bottles.
(2) Change the thing that is in bloom
These plastic bottles were originally used to hold water, drinks, juices and tea, but in real life some people are Xi using them to hold vinegar. Not only at home, but also in fast food restaurants and small restaurants outside, we can often see this kind of bottled vinegar with drinks.
The pH of vinegar is very low, and the vast majority of PET plastic bottles are likely to be produced with a metal catalyst called "antimony". This "antimony" has an increased migration rate in both acidic and alkaline environments.
Antimony has certain biological toxicity and causes damage to our tissues and organs such as skin, heart, kidneys, and liver. Although the damage and impact of small doses of antimony on the human body is not obvious, it is afraid that it will accumulate over time for a long time, which will inevitably cause irreparable damage to the human body.
(3) Hold something for a long time
Since plastic bottles can't be used to hold spices such as hot water, oil, and vinegar, it's okay to use them for rice, millet, beans, etc., right?
It seems to be seamless and flawless, but in fact there are big holes. Beverages and bottled water have a shelf life, in fact, this shelf life is not only the shelf life of the product itself, but also the shelf life of the plastic bottle.
Many people may have heard of this concept for the first time, but in fact PET will age with long-term use and exacerbate the migration of harmful substances. When we use plastic bottles for rice and beans, we usually pack them for a long time, and many of them are still placed next to the stove, which naturally poses health risks.
Pay attention to the repeated use of plastic lunch boxes!
Some people are Xi to put plastic lunch boxes directly in the microwave oven to heat, here need to be reminded that most plastic lunch boxes can not be heated.
There are 3 kinds of standards for plastic lunch boxes: 1 (PET), 5 (PP) and 6 (PS), we have said earlier that the heat resistance of PET is 70 °C, PS is 90 °C, and only the heat resistance of PP material has reached 130 °C, that is to say, only PP plastic lunch boxes can be put into the microwave oven to heat.
However, it is still necessary to remind that even if it is a disposable lunch box made of PP material, try not to use it many times. After all, it is a one-time product, and some merchants generally do not have high security standards in order to control costs. Therefore, once used many times, it may destabilize it and lead to the precipitation of harmful substances.
Plastic bags in the supermarket, don't take them home again!
Many people like to take the plastic bags in the supermarket and use them at home, and when we eat at some roadside stalls and small restaurants, merchants also like to use disposable plastic bags to cover the bowls and save the need to wash the dishes. As everyone knows, these practices are all "chronic poisoning"!
Most of these plastic bags are made of PE material, of course, we can't think that we can use PE as soon as we see it, PE as a very broad concept, in order to fit different use scenarios, so different additives and production processes will be used.
First of all, this type of plastic bag should not be used to hold hot food and hot food, because its heat resistance is very poor, and it cannot exceed 80°C. Once this temperature is exceeded, phthalates may be precipitated, which is a harmful substance, and long-term use of this plastic bag to pack hot food is very harmful to the human body.
Secondly, it cannot hold frozen food. After buying frozen meat or frozen food at the supermarket, we are Xi to stuff it directly into the refrigerator when we get home. As everyone knows, the sealing of this kind of plastic bag is generally very poor, resulting in the meat is easy to spoil under the action of microorganisms and bacteria in the refrigerator.
Finally, this kind of PE plastic bag should not be used to contain high-fat food and food containing alcohol, such as wine, vinegar, fried chicken, pickled cabbage fish, spicy tang and Mao Xuewang. This can cause the bag to break and leak after dissolving, eventually precipitating harmful substances.
A seemingly convenient and thrifty life Xi, I didn't expect that there was such a big hidden health risk, for the sake of health, we must remind our family not to do this again!
