First, there will be building the new gym pollution, such as radioactive radon, ammonia pollution and indoor decoration and furniture caused by formaldehyde, benzene pollution. Radon exists in the construction of cement, slag brick and decorative stone and soil, the main hazards on the human body is the cause of lung cancer. Ammonia mainly from concrete antifreeze, formaldehyde, mainly from the various boards, such as plywood. Benzene in paint, glue and a variety of interior wall paint, can cause cancer or blood disease.
Second, the body in its own air pollution. There are the following:
1, carbon dioxide pollution. Mainly carbon dioxide from human breath, studies have shown that human activity is different from the amount of carbon produced is different, when intense activity is still about 10 times, in particular the crowded room, ventilation, easy people produce nausea, headache and discomfort, this is because due to increased carbon dioxide levels. Indoor concentrations of carbon dioxide not more than 0.15%, and as assessment of indoor air pollution.
2, movement caused by particulate matter pollution. Because people generally refers to movement on the ground is dust and clothing, footwear, skin off, etc., which is less than 5μm particle size of particles can be inhaled human respiratory system, or even into the lung cells. Particulate matter may not only be the carrier of microbes, which itself contains toxic substances or other pathogens, carcinogens.
3, surface emissions of ozone and microorganisms. Indoor air odor substances are mainly ammonia, methyl mercaptan, hydrogen sulfide, methyl disulfide trimethyl amine, acetaldehyde, styrene. Same bacteria, viruses and was accompanied by air particles, dust can also be changed with the change of air. Especially in the public areas are concentrated, can be found in a large number of microorganisms in the air and suspended particles.
Third, noise pollution. Fitness movement and sonorous voice loud and clear st
