Experts pointed out that due to renovation process caused the greatest impact on indoor air pollutants on human health can be broadly divided into three categories: First, respirable particulate matter, such as dust, major serious violations of the human respiratory system and digestive system; the second is a microorganism class,pittsburgh ultra stain reviews such as bacteria, viruses and the like; third is organic and inorganic hazardous air pollutants, such as formaldehyde. Among them, the dust is not lower than we usually are familiar with the dangers of formaldehyde, known as the decoration of the "invisible killer." Dust hazard Big Secret On the surface of dust it does not directly hurt, but in fact this substance from various phenols and hydrocarbons, and contains a strong carcinogenic substances, especially flour dust particle size less than 10pm less, grain small lightweight , directly into the lung tissue, mucosa damage.

human health violations as long as reflected in the following major areas: 1, systemic violations Long-term inhalation of high concentrations of dust can cause lung diffuse, progressive fibrosis based systemic disease (pneumoconiosis); If inhaled toxic dust can be dissolved in the bronchial wall is absorbed by the blood to the whole body,4x8 dog eared wooden fence causing systemic poisoning, central nervous system, respiratory system and digestive system serious injury. 2, local infringement Contact or inhalation of dust, firstly, skin, cornea and mucous membrane irritation and other local produce, and produce a series of lesions. As dust acts on the respiratory tract, can cause nasal mucosa early hyperactivity, telangiectasia, a long time they formed hypertrophic rhinitis, finally due to inadequate supply of nutrition mucosal form of atrophic rhinitis.

It may also be formed pharyngitis, laryngitis, trachea and bronchitis. Acting on the skin, can form acne, folliculitis, pyoderma, such as lead dust immersed skin, there will be some red spots,plastic wall sheathing called "lead rash" and so on. 3, carcinogen-induced Intensive contacts such as nickel, chrome, chromate dust, can cause lung cancer; exposure to radioactive mineral dust, easy to generate lung cancer; asbestos dust can cause skin cancer.
