Nowadays, people have paid attention to the internal pollution caused by the household decoration. The decorative materials can release various toxic chemical substances, such as formaldehyde and benzene. These substances are the essential components of decorative materials. In order to maintain the physical health and avoid unnecessary dangers, it is necessary for people to try their best to eliminate these toxic substances. Four ways will be introduced to help people eliminate the substances as far as possible.

First, people can make full use of the natural ventilation to alleviate the toxic tastes. It is convenient for people to open the windows during the day to release the substances. However, it usually takes 3 to 15 years to release all the chemical substances by the natural ventilation. It can be seen that the existence of such substances is a long-term pollution source to threaten the human health.

Second, people can use certain articles like plants and active carbon to absorb the chemical matters. These articles can absorb the toxic substances positively. However, these articles can not dissolve these chemical matters. The physical health of the human body is always threatened.

Third, people can use some sweet chemical products like air freshener and perfume to cover the toxic tastes. It is true that these chemical products can indeed cover the toxic tastes caused by the household decoration. However, these products can also worsen the quality of air inside the house, as they contain benzene series. The poisoning can be thus caused. The symptoms of mild poisoning include headache, emesis and so on. The symptoms of serious poisoning include fuzziness of eye vision, arhythmia and unconsciousness. Sometimes, the normal functions of the nervous system can be seriously disturbed. Therefore, according to the experts, people should choose these products carefully.

Fourth, people can use relative medicines and mechanical devices to deal with the formaldehyde and benzene together. A single way can not treat the inner pollution effectively and completely, as the variety of the internal pollutants is rather diverse. Therefore, people should make full use of skillful ways at the same time. For example, they can use relative medicines to deal with the decorative pollution. At the same time, they should use the air cleaner to dissolve the toxic substances. Of course, the natural ventilation should not be ignored, as it can constantly decrease the density of toxic substances including formaldehyde, benzene and ammonia inside the house.
