Construction and interior decoration materials using some housing construction materials contain formaldehyde, radon and asbestos are prone to air pollutants, especially formaldehyde, which is a component of adhesives plywood, furniture and carpets can emit formaldehyde. Therefore, many air formaldehyde content exceeds a predetermined standard family room. Radon mainly from brick, concrete, stone, soil and water systems. Modern housing construction in Nanjing Xuanwu District pm2.5 detection, for insulation, fire detection pm2.5 Jiangning District of Nanjing, widespread use of asbestos, which would make indoor air pollution asbestos fibers. PM2.5 affect fetal development caused by defects and some find pm2.5 detection, people more worried. Some reports in recent years have shown that human reproductive capacity are decreased, environmental pollution is considered to be the culprit. From northern Bohemia, a survey in Nanjing Yuhua District pm2.5 testing of pregnant women exposed to high concentrations of PM2.5 were investigated and found high concentrations of fine particulate matter pollution may affect the development of embryos. More research found that the atmospheric concentration of particulate matter perinatal, neonatal mortality rise, low birth weight, intrauterine growth retardation (IURG), and congenital dysfunction relevant.
