Formaldehyde preservation? It is not worthwhile

Formaldehyde aqueous solution is commonly known as formalin.

It is embalmed, sterilized, and bleached, and is best known for its use in animal taxidermy. radiation detectors for sale At this point, it seems reasonable to use it to soak vegetables and keep them fresh-if cost is not taken into account.

Talk about formaldehyde color change? exaggerated

There is no doubt that formaldehyde is harmful to human health. It is classified as a carcinogen by the International Agency for Research on Cancer (IARC), part of the World Health Organization.

When inhaled or ingested in large quantities, formaldehyde becomes formic acid/formic acid and then carbon dioxide, which is exhaled with breath. When excess formaldehyde accumulates in the body, the enzymes in the body cannot process it. Formaldehyde may cause proteins to change properties or become inactive, causing damage.

But the concentration of formaldehyde is related to the condition. Studies have shown that people do not experience significant sensory stimulation until the formaldehyde concentration exceeds 1mg/m3(10 times the national standard).

Moreover, we ourselves actually live in the "enveloping circle" of formaldehyde, which can be seen everywhere in the entire human economy and society, and even affect everywhere:

Cooking at home, frying, will produce formaldehyde;

The adhesives used for home furniture are formaldehyde;

Household cleaners and disinfectants, which produce formaldehyde when oxidized;

Formaldehyde is even found in smoking and car exhaust.

With the metabolism of each of our tissue cells, even the human body will produce a lot of formaldehyde.
