Nanjing Jianye District housing formaldehyde detection | Nanjing formaldehyde detection | Good New Plaza environmental testing

Air pollution damage to human body (1), infants and children affect children's developing body, the immune system is relatively fragile, additional children's respiratory volume 50% higher according to the weight Bibi adult Nanjing Xuanwu District housing formaldehyde detection, which making them more vulnerable to indoor air pollution hazards. In terms of physical or mental development of children, the indoor air pollution harmful to children can not be ignored! Indoor air pollution on children constitute the following three major threats: Child-induced blood diseases (such as leukemia); increased incidence of childhood asthma (According to statistics, prevalence of asthma in children 2 to 5%, where the 1 the prevalence of children under 5 years up to 85%); affecting children's height and mental health development. China's primary and secondary schools and kindergartens in the classroom, generally less space per capita, while teachers and students in the classroom learning time and up to 6 to 8 hours. Because many people with poor ventilation and prevailing circumstances, many classrooms are CO2 concentration of formaldehyde detected in more than 2000ppm, CO2 concentration will be higher in the winter, directly affecting the health of staff and students and learning efficiency, in the formative years The children lower resistance than adults, so more vulnerable to bad air hazards. Air pollution control measures (1), from time to time to monitor indoor air quality, achieve scientific and effective window ventilation to keep indoor air circulation Jiangning District of Nanjing housing formaldehyde testing to ensure indoor fresh air, most significantly reduce indoor air pollution on the human body cause to hazards; (2) lighting. Refers to residential natural light can be effective in the general area of ??the window and the room floor area ratio should be greater than 1:15. Sunlight can kill microorganisms in the air, improve the body's immunity. Experts believe that in order to safeguard human health and the normal development time sunshine room must be at least two hours a day; (3), preferably higher than 2.8 m ceiling height. The standard is "civil design Quota" regulations. The occupants, the appropriate clear height gives a good sense of space, clear height is too low will make people feel depressed. Experiments show that Nanjing Yuhuatai housing formaldehyde detection, when the home is less than the clear height of 2.55 meters, high indoor concentrations of carbon dioxide, a significant impact on indoor air quality; and (4) improve the microclimate. To make room to maintain a good health condition, generally require temperature not lower than 12 degrees Celsius in winter, summer is not higher than 30 degrees Celsius. Indoor relative humidity less than 65%, the summer wind speed of not less than 0.15 m / s, winter is not greater than 0.3 m / sec.
