In rural areas, every family has a large iron pot for cooking or other purposes.

production activities should be carried out in rural areas, and then some livestock should be raised.

Those big iron pots will be used to cook some food for livestock, and they will also be used to do business in the countryside and stir-fry in large iron pots.

why does every family have a big iron pot? Large iron pots are more convenient for them, and they are cheaper.

some people in the countryside still use firewood. If firewood is used in large iron pots, the family will be faster, and if it saves time, it will also save firewood.

It's a good choice for them, but they don't know some dangers behind it.

first, CCTV exposed that the big iron pot became a deadly pot.

as we all know, the dishes fried in a large iron pan are different from the usual ones. The dishes fried in a large iron pan are more delicious, and vegetarian food cooked in an iron pan is a good thing for people with iron deficiency.

But CCTV exposed the use of a large wok and turned it into a poisonous wok, which was poisoned by heavy metals. What about this?

CCTV news first reported the manufacturing materials of large iron pots.

They use discarded iron sheets. Normal iron sheets are much more expensive than those of airplanes.

in order to save money, they use scrap iron with heavy metals.

However, if the iron sheet is discarded, it doesn't carry a lot of toxic heavy metals.

most of them are chemical waste barrels.

The workers poured the chemical waste barrels into a sulfuric acid tank for soaking, and then put them into a high-temperature furnace for polishing and burning.

the workers said that this was done to remove harmful substances from the iron sheet.

but the effect is not obvious.

Because high temperature decomposes harmful substances, it can also penetrate those bad things into the iron sheet.

In this case, all the iron pots you buy contain toxic substances.

second, the classification of iron pots

everything has its classification, just to enable them to better identify the specifications and production, and different prices also have different quality.

woks are divided into raw woks and cooked woks. The raw woks are heated slowly, and the pots are rough and have uniform heat transfer.

Compared with the raw wok, the cooked wok is thinner in texture and faster in heat transfer, so it is called refined wok.

A regular wok is good for human health.

but their prices are relatively expensive.

The cost is relatively high, and fewer people buy it. In order to earn more money, most people use iron pots made of scrap iron.

Only a few people can buy iron pots that are really beneficial to human health.

The iron pots that most people usually use look good, but they are actually made of scrap iron with excessive heavy metals.

if you use too much, those heavy metals can penetrate into food, which will have an impact on human health. When buying an iron pot, you must pay attention to its price and quality.

3. How does a large wok produce poison in the process of cooking?

how does the iron pot produce poison, which has a bad influence on the human body.

the ratio of heavy metal to scrap iron is heavy metal.

Moreover, his high-temperature heating did not remove heavy metals. On the surface, some procedures were used to remove bad substances, but in essence, harmful substances remained in the iron sheet.

toxic chemicals, the current iron pans are coated on the outside, just to make money.

most people use unqualified woks, but in the process of cooking, when the wok is heated, those harmful substances can penetrate into the food, and after a long time, the human body will have adverse changes.

Long-term use of wok for cooking will lead to lead poisoning.

lead poisoning will make children slow down.

and it has many serious diseases, and ADHD is the most important manifestation of lead poisoning.

pregnant women, in particular, will have a serious impact on the unborn baby, leading to such a serious situation as congenital malformation.

so how can we choose a qualified wok?

fourth, how to choose a qualified iron pot?

The raw materials for making woks come from every place, and the iron sheet in every place contains different heavy metals.

then you should pay attention to the following aspects when choosing a wok.

First of all, the price. We often say that cheap goods are not good. This statement may not be correct, but what is cheap depends on what it is. If it is just a gadget in life, it is ok.

This is our daily necessities. We must buy some more expensive ones. They are all more expensive and more secure.

The price difference between a pot made of scrap iron and a normal one is much lower.

if it's a regular wok, it can't be sold very cheaply, because the cost is very high.

be alert, and don't let people at home get poisoned.

Secondly, look at his certificate and smell. Every qualified wok has his certificate, not only for other utensils.

if you don't have a qualified certificate, don't buy it.

And smell. Regular iron pots have no smell.

And the informal wok has a pungent smell.

conclusion:

we must strictly control the things that have an impact on our lives, and don't have an impact on our health because of our negligence and greed for petty gains.

Some injuries are irreversible, and long-term use will have side effects on human body.

You should spread this knowledge to the people around you, so as to prevent them from being cheated and having a bad influence on their health.
