Indoor pollution hazard
Office white collar
White-collar elites work in the environment with poor air quality for a long time, which can easily lead to dizziness, chest tightness, fatigue, emotional ups and other discomforts, which greatly affect work efficiency and cause various diseases. In severe cases, it can cause cancer, and the office environment changes. It became an invisible healthy chronic killer.
Nowadays, more and more white-collar workers and staff complain that the office is dirty, feels poor breathing, and lacks concentration, resulting in reduced work efficiency. According to experts from the China Center for Disease Control and Prevention, due to the relatively closed office space, air is not circulating, air is dirty, and oxygen content is low, which tends to reduce the metabolism of the body and brain.
Women, especially pregnant women
Indoor air pollution, especially the decoration of harmful gas pollution, has a relatively greater impact on the female body. Because women have more fat, benzene is easily stored in fat after absorption, so women should pay more attention to the harm of benzene. Women should avoid exposure to decoration pollution before pregnancy and during pregnancy. Many cases at home and abroad have shown that benzene has adverse effects on embryonic and fetal development, and can cause fetal malformation and stillbirth in severe cases.
The investigation found that the free formaldehyde is a suspicious carcinogen in various wood-based panels, glues, etc. used in decorative materials and furniture. Long-term exposure to low concentrations of formaldehyde can cause chronic respiratory diseases, female menstrual disorders, pregnancy syndrome, causing neonatal physical decline; high concentrations of formaldehyde are toxic to the nervous system, immune system, liver, etc., can also induce fetal malformations, infants Early childhood leukemia. When the concentration of formaldehyde in the indoor air is 0.24-0.55 mg per cubic meter, 40% of the women of the appropriate age have irregular menstrual cycles.
In 2001, the report of the UK’s Global Environmental Change Research Group’s report put forward a thought-provoking conclusion: the increase in environmental pollution will lead to a decrease in children’s immunity and intelligence! The child’s body is developing, the immune system is relatively fragile, and the child’s breathing rate is 50% higher than that of the adult, which makes them more vulnerable to indoor air pollution. Regardless of the child’s physical or intellectual development, the harm of indoor air pollution to children can not be ignored!
When the human body enters the old age, various body functions are declining, and it is more susceptible to environmental factors that induce various diseases. Air pollution is not only an important cause of respiratory diseases such as bronchitis, pharyngitis and pneumonia in the elderly, but also induces hypertension, cardiovascular, and cerebral hemorrhage. It may also be life-threatening for the infirm.
According to the American Heart Disease Society’s “Circulation” magazine, in 1982, 500,000 adults volunteered to participate in a cancer prevention survey conducted by the American Cancer Society. More than 20 years later, researchers at Brigham Young University in Utah analyzed the survey data to investigate the incidence of cardiovascular diseases such as respiratory diseases and heart disease, and air pollution data from more than 150 cities in the US Environmental Protection Agency. In connection with the data, data show that among the diseases caused by air pollution, heart disease patients are mostly.
Respiratory disease patients
Long-term living in polluted air can cause decreased respiratory function, increased respiratory symptoms, and some can lead to chronic bronchitis, bronchial asthma, emphysema and other diseases. The prevalence of lung cancer and nasopharyngeal cancer will also increase. According to statistics, acute respiratory infections caused by air pollution worldwide kill about 4 million children every year. Domestic and foreign investigations have shown that respiratory infections are the most common diseases in humans, and their symptoms can range from latent infections to life-threatening.
