In summer, especially the rainy season, the humidity and temperature of the climate are suitable for breeding eggs. Housewives inevitably put some moth-proof products in the wardrobe to ensure safety. However, few people know that the substances emitted by mothball enter the human body with the clothing passing through the skin, causing great harm to the human body. People have been accustomed to using mothball of various shapes (such as mothball, mothproof jasmine scented green tea, net pocket bags of blocks, hanging fragrant cakes, synthetic camphor) and so on, which are extracted from petroleum or coal tar, it is a colorless, transparent, flammable hydrocarbon with special aromatic smell, and has been processed to become a moth-proof product of various shapes. Its main components are: P-dichlorobenzene, naphthalene and synthetic camphor. They have both strong volatility and certain toxicity.
Mothball containing p-dichloro and naphthalene belongs to agricultural products, which are generally used for moth prevention of industrial products or agricultural products. Not suitable for life products. A large number of practices have proved that benzene substances are extremely harmful to human health. Therefore, the World Health Organization has designated it as a strong carcinogen.
At present, anti-moth products with mothball as the main body in the market contain the above ingredients, but merchants cover up this fact for profit. Knowing that this kind of product is harmful to human body, it is said that this product has low toxicity or does not contain toxic ingredients, etc. No matter what kind of signboard the merchant carries, the toxic substances in the raw materials will never change.
Lu Shuyu, director of Shanghai radiation management office, said: "The content of dichlorostupid in anti-moth agent is more than 95%, which belongs to toxic volatile organic compounds. Long-term contact of human body can cause dizziness, vomiting, skin allergy, limbs' numb and other symptoms. Excessive use can also cause pulmonary dysfunction, liver damage, acute hemolytic anemia, respiratory tract irritation, etc. It can even cause cancer in severe cases." Jin Xipeng, a professor of toxicology at the School of Public Health of Fudan University, once made a special study on the toxicity of p-dichlorobenzene. He believed that even if p-dichlorobenzene were used to prevent moth, they should be used cautiously, especially to protect the elderly and children. Because P-dichlorobenzene can be inhaled by human body through respiratory tract, the use of contaminated food and local skin contact may also cause poisoning. According to his introduction, a large number of experimental studies began in the late 1940 s p-dichlorobenzene abroad, believing that it has liver and kidney toxicity and also affects thyroid gland, high-dose use is definitely carcinogenic to animals and suspicious carcinogen to human body. The p-dichlorobenzene of mothball and synthetic anti-moth agent can hardly be seen in the markets of developed countries such as the United States and Japan, in 1995, Lu Kezhu and others wrote an article in Volume 11 of Chinese Journal of Public Health, Volume 9, Department of Labor Health, Shanghai Medical University...... In the overview of p-dichlorobenzene and toxicity studies, it is pointed out that "it can indicate that p-dichlorobenzene has hepatorenal toxicity and may also damage thyroid gland...... It is definitely animal carcinogen ". In 1996, "foreign medical hygiene division" published an article by Xu Dandan, environmental health testing institute of Chinese Academy of Preventive Medicine...... "Toxic effects and carcinogenicity of p-dichlorobenzene" points out that "acute or short-term exposure P-DCB (abbreviation of p-dichlorobenzene) can cause acute hemolytic anemia, respiratory tract irritation, skin anaphylactoid purpura and glomerular nephritis. Long-term exposure P-DCB months to 15 years can affect the lung, blood, central nervous system, and damage the liver.
Hefei "Luzhou home" emphasized this point in the third issue of 2005, warning people to be alert to the healthy aromatic killer "Benzene". Benzene is the most important aromatic hydrocarbon, such as Alkylbenzene (decontamination agent), hair dye, insecticide, anti-agent (mothball), plastic products, etc. related to benzene. A large number of facts above prove that various aromatic shapes mothball repellents, which is harmful to human body. It is absolutely not allowed to be used as moth-proof for household articles (such as wardrobes, furniture, books, etc.).
