I ve been hoarding drinking water in plastic buckets for more than ten years, and I don t know if it

Storing drinking water in plastic buckets for too long may produce some harmful substances that affect human health.

The composition of plastics usually contains a variety of chemicals such as polyethylene and polypropylene, which will not cause harm to the human body at room temperature and pressure. However, in the case of high temperature or combustion, plastic barrels may release harmful gases such as formaldehyde, benzene, etc., which may have a negative impact on human health.

In addition, plastic buckets can also be subject to wear and tear or aging during use, causing their chemical components to leach out, which can affect the quality of the water.

It is recommended not to use plastic drums for long-term storage of drinking water, and it is better to use food-grade stainless steel or glass containers for drinking water. At the same time, if it is found that the plastic barrel is worn or aged, it should be replaced with a new barrel in time.

The most common plastic on the market today is polyethylene.

Polypropylene and polyvinyl chloride.

Three kinds. Among them, polyvinyl chloride is toxic to living organisms and cannot be used to package food, and the other two are non-toxic and can be used with confidence. When used, it can be distinguished from the following method:

1. Fire burning method. If the plastic is ignited and emits white smoke, produces a choking odor or extinguishes itself after leaving the fire, it is a toxic plastic; If there is a drop of plastic after combustion and there is no smoke or only a small amount of black smoke, and it continues to burn after the fire, it is a non-toxic plastic.

2. Sinking and floating method. Plastic sheets or plastic pipes (filled with water) are placed in the water, and the toxic plastic that sinks to the bottom of the water and floats on the surface of the water is non-toxic plastic.

3. Softening method. When the plastic is sunk into 100 percent of water, the toxic plastic softens first, while the non-toxic plastic softens more slowly.

There are no toxic substances in the current plastic bottled drinking water, the main reason is that the current plastic barrels are made of food grade, so you can continue to use it with confidence.

If it is not heated, it should be non-toxic, it should be fine, rest assured.

There are generally several components of plastic barrels: PC, PP, and PVC, and their identification is respectively.

The PC upstairs contains bisphenol A (environmental estrogen BPA), which will be released after a long time, and I don't think the PC barrel will release it under normal circumstances. Nowadays, there are many reports that this substance is released when PC milk bottles are filled with boiling water, but my opinion is: if it is made well, it should not be.

Some experts say that there is a chance to release it only if there are scratches. Even if it is released, it should be very small, and whether this is toxic to the human body or not should not be confirmed by authoritative experiments. So don't worry about that.

However, a friend told me that the service life of PC plastic buckets is generally 3 years. After this age, it is easy to breed bacteria, damage the water quality in the bucket, and the toxic substances in the plastic will also dissolve in the water with the aging of the bucket, which is harmful to the health of drinking people.

Then there's PP, a plastic cup or bowl that can be baked in the microwave. So no problem.

Finally, when it comes to PVC, there are also baby bottles made of PVC. It's no problem to fill water, toxic substances will be released when burning, but don't use it to hold oil, PVC will also release toxic substances when it encounters oil.

There are many other varieties of barrels, you can see for yourself what the sign is made of, and then ask the person.

Mainly look at the raw materials, the raw materials are non-toxic, and there will be no problem if toxic substances are not added in the production process.

The plastic bucket contains PC, which contains the toxic substance bisphenol A, which will be released after a long period of use. Therefore, it is necessary to change the barrel once a year, and it should be eliminated.

The water in plastic barrels, after sampling, is tested according to the corresponding standards, meets the qualification regulations, and is non-toxic.

Whether plastic bottled water is harmful, depends on whether the materials and additives of the barrel are toxic, if they are not toxic, they are harmless, otherwise they are harmful, because the toxic materials and additives are cheap, so most of the non-food packaging plastic barrels are used, so most of the non-food packaging plastic bottled water is harmful. And food-grade plastic bottled water is harmless.

See if you are suitable for food grade, you can find Zhedong containers, there are seven branches in the country, and they can be shipped nearby.

In this way, the long-term discharge of water in the barrel will release some toxins.

Yes Drinking it regularly is easy to form a habit.

Use it right away, the water will spoil after a long time.

Cold water should be fine, boiling water is probably not. It's better not to use it.

To tell you a little common sense, all drink bottles can not be used again, basically all are disposable, because you are filled with warm water, not cold boiled water, so the bottle, the surface will have a certain toxic substance, it is recommended to use it at most once, do not reuse,

Iron products are still OK, as long as plastic products are not used in high-temperature liquids, there is no problem, it is recommended not to use plastic products frequently. One is bad for the body, and the second is polluting the environment.

The plasticizer will be released slowly.

Long-term use of plastic cans is harmful to health, it is best to use ceramic cups or glasses, if the conditions do not allow iron cans are also possible, stainless steel will not rust, unless you buy a fake.
