What is the relationship between office environmental pollution and health?

According to the investigation of indoor environmental pollution in office buildings for many years, China Indoor Environmental Monitoring Committee found that "office building syndrome", which is common in office buildings in China, has become a major problem endangering the health of mental workers. Mr. Liu of an internet company said that more than a dozen colleagues in the company had a strange disease at the same time: dizziness and headache as soon as they entered the office, and it was even worse in the afternoon. Later, they learned that it may be caused by the working environment. Unexplained troubles, general malaise, inability to work, tinnitus, eye fatigue, mental retardation, decreased sexual desire, etc. , caused by the new working environment, has become the mainstream of urban occupational diseases.

Regarding the environmental pollution of offices, in addition to the indoor air pollution mentioned above, offices often adopt closed central air conditioning. Due to poor ventilation in the confined space, the indoor oxygen content decreases and carbon dioxide increases, which leads to the lack of oxygen, dizziness, chest tightness, inattention and slow thinking of the staff inside. In addition, office carpets and furniture can also emit all kinds of harmful gases and irritating volatiles mentioned above, including formaldehyde, benzene and toluene diisocyanate (an irritating gas in polyurethane coatings and adhesives), which will cause cancer if exposed for a long time. Because the central air conditioner is often rarely cleaned, the pipes are full of dust, dust mites and bacteria, which enter the office with the air supply outlet of the air conditioner and easily lead to respiratory infection. In addition, all kinds of electrical equipment in the office, such as computers, photocopiers, laser printers, telephones, etc. Noise and electromagnetic pollution often occur, which is also an important reason for dizziness, discomfort and irritability.

The closed building retains all kinds of indoor pollution, especially those unpleasant smells: shampoo for carpet washing, disinfectant for disinfection in public places, irreplaceable old mimeograph, liquid in typewriter, pen, glue and air freshener. These harmful gases will be deposited in a closed room, which will not only lead to nasal congestion and dyspnea, but also lead to chronic headache, nausea, dizziness, sore throat, eye and skin irritation, dry cough, allergies and even insomnia. What's more, these closed rooms must be equipped with humidifiers and air conditioners to adjust the indoor humidity and temperature, which creates an ideal environment for the breeding of bacteria or fungi. The well-known result of this situation is legionnaire's disease (a kind of lobar pneumonia), and many people with this disease died before the cause was clear.

Some people sampled the indoor air quality of six high-grade office buildings in Beijing and found that the rate of harmful substances such as ammonia, formaldehyde and ozone exceeded the standard was 80? 56%、42? 1 1% and 50%. These excessive substances will not only cause headache, nausea, shortness of breath, nasopharyngeal discomfort and other symptoms, but also produce bad emotions such as anxiety, which will seriously lead to lung cancer and leukemia. At present, the incidence of lung cancer in China is 26? 9% is increasing at an alarming rate, with 50,000 new leukemia patients every year, and 80% of the incidence rate is directly related to indoor air pollution. Therefore, we should pay attention to the invisible killer in the office building-office environmental pollution.
