Formaldehyde is a common indoor air pollutant, mainly due to the release of formaldehyde in building materials such as decoration and furniture. Long-term exposure to excessive formaldehyde can cause serious harm to the human body, such as causing symptoms such as headaches, dizziness, nausea, and may even lead to serious diseases such as nasopharyngeal carcinoma and leukemia.
We should choose environmentally friendly building materials that meet national standards, and try to avoid using materials containing harmful substances such as formaldehyde. Strengthen indoor ventilation and regularly open windows for ventilation to ensure air circulation.
At the same time, you can place some green plants, such as spider plants, pothos, etc., these plants can absorb formaldehyde and other harmful substances and play a role in purifying the air.
In addition, professional formaldehyde treatment measures can also be adopted, such as inviting a professional treatment company to carry out indoor formaldehyde treatment, using formaldehyde decomposers, etc., which can effectively reduce the concentration of indoor formaldehyde and protect our health.
First of all, cabbage is rich in many vitamins. It contains vitamin C, vitamin K, vitamin A, and vitamin B6. These vitamins are essential for human health and each plays an important physiological function.
For example, vitamin C helps boost immunity, vitamin K has a positive effect on bone health, vitamin A is essential for vision maintenance and health, and vitamin B6 plays an important role in metabolic processes.
Secondly, cabbage is also good for minerals**. It is rich in minerals such as calcium, magnesium, potassium, iron, etc., which are very important for the health of the body.
Calcium is a major component of bones, magnesium is involved in energy metabolism and nerve function, potassium helps maintain fluid balance in the body, and iron is an important component of hemoglobin and is involved in oxygen transport.
In addition, cabbage contains a lot of dietary fiber. These dietary fibers can promote intestinal motility and prevent constipation and other digestive problems. For many people, maintaining adequate dietary fiber intake is key to maintaining healthy bowel function.
Cabbage also contains some compounds that have antioxidant effects, which can help protect against cardiovascular disease and certain cancers. By consuming foods rich in antioxidants, people can get this protection.
Finally, the iron in cabbage also helps prevent iron deficiency anemia. Iron is the main component of hemoglobin in red blood cells and is essential for oxygen transport. By including cabbage in their daily diet, one can ensure that they are getting enough iron, which reduces the risk of developing anemia.
First of all, these cabbages have an unusually bright appearance and look brighter than ordinary cabbage, because formaldehyde can play a role in preservative and preservation.
Secondly, the cabbage leaves sprayed with formaldehyde will appear particularly stiff and not prone to wilting, because formaldehyde can keep vegetables hard and prolong the shelf life.
Finally, these cabbages will weigh a little heavier than normal cabbage, because the water absorption of formaldehyde will increase the water content of the vegetables.
When buying cabbage, we need to pay special attention to the above three characteristics, so as not to mistakenly buy cabbage sprayed with formaldehyde. It is very important for consumers to choose fresh and healthy vegetables, so we need to learn to recognize whether vegetables have been processed improperly.
First of all, formaldehyde can cause damage to the respiratory system. Prolonged inhalation of formaldehyde will irritate the nasal cavity and throat, causing symptoms such as cough and chest tightness. In severe cases, it may also lead to pneumonia, laryngeal cancer and other diseases. In addition, formaldehyde can also affect lung function, reduce lung capacity, and increase the risk of chronic obstructive pulmonary disease.
Secondly, formaldehyde also has a certain stimulating effect on **. Long-term exposure to formaldehyde will make ** become dry, sensitive, and even appear redness, swelling, itching and other symptoms. In addition, formaldehyde may also cause systemic symptoms such as headache, dizziness, and fatigue, and have an impact on the nervous system.
In addition, long-term exposure to high concentrations of formaldehyde may also increase the risk of malignant diseases such as nasopharyngeal carcinoma and leukemia. These diseases are not only harmful to health, but can also place a huge financial burden on families.
To choose fresh cabbage, you must first learn to distinguish the color of cabbage. Fresh cabbage leaves should be green without any yellow spots or signs of discoloration. If the leaves are yellow or spotted, the cabbage may not be fresh.
Secondly, pay attention to the firmness of the cabbage. Fresh cabbage should be firm and plump, with no gaps between the leaves. If the cabbage is loose or there are gaps between the leaves, it means that the cabbage may have been stored for too long and lost moisture.
In addition, to choose fresh cabbage, it is also necessary to learn to distinguish the smell of cabbage. Fresh cabbage should have a refreshing taste without any off-flavors or oddities. If there is a peculiar or strange smell, it means that the cabbage may have gone bad.
Finally, pay attention to the weight of the cabbage. Fresh cabbage should be heavier because there is enough moisture. If the cabbage is flirtatious, it means that it has lost its moisture and is not fresh.
Formaldehyde is a common indoor air pollutant, mainly found in furniture, boards, paints, glues and other decoration materials. The formaldehyde in these materials will be gradually released after renovation, causing pollution to indoor air.
In addition to decoration materials, formaldehyde may also be present in some household items, such as curtains, carpets, mattresses, etc., and even some foods contain trace amounts of formaldehyde.
Since formaldehyde has a low boiling point and is volatile, materials used in renovation and new furniture are the main source of formaldehyde release. Especially in some panel furniture, formaldehyde in the glue will be gradually released into the indoor air. In addition, some glue adhesives, paint solvents, etc. are also one of the ** of formaldehyde.
In addition to decoration materials, formaldehyde in household products may also cause indoor air pollution. For example, some manufacturers will add some formaldehyde in order to increase the wrinkle resistance and flame retardancy of household items such as curtains, carpets, and mattresses. These household items also release formaldehyde into the indoor air during use.
In addition, some foods may also contain trace amounts of formaldehyde, such as jellyfish, squid and other aquatic products, and the formaldehyde in these foods may be caused by environmental pollution or the addition of formaldehyde during processing.
Therefore, in order to reduce indoor formaldehyde pollution, we should choose decoration materials and household items that meet environmental protection standards, and try to avoid using formaldehyde-containing adhesives and other materials.
At the same time, strengthening indoor ventilation is also an effective way to reduce formaldehyde pollution. For houses that have been renovated, professional formaldehyde treatment products can be used for purification treatment to ensure the safety and health of indoor air quality.
