When the formaldehyde in indoor air to gas accumulation to a certain degree, will produce great harm to human body health.People live, work, then, indoor if there is a serious of formaldehyde pollution, and how do you know?From the point of practical experience and scientific research, there are three main ways:

(1) passive sense

Some pollutants on human sense organs such as the sense of smell, may stimulate the visual organ, people can use these sense organs, according to some characteristics to determine whether there is con***ination.A high concentration of formaldehyde can stimulate an eye tears, dry throat discomfort, etc.

(2) plant growth observation method

If indoor air pollution is serious, so some of the more sensitive plants and trees, as the rich tree, black beauty, and plants such as unusually large yellow, falling leaves wither, until they die.If the trees, flowers and other plant itself and rearing method without errors, so basically can be identified inside the bedroom has a serious air pollutants.

(3) the scientific

Formaldehyde moment exists in people's articles for daily use.When the concentration of pollutants is relatively low, the feeling is not very obvious, especially in the indoor stay a long time later, we'll feel out of these pollutants excitant, perhaps just the body fatigue, discomfort, formaldehyde may still exist, but there is also a harm to human body, so it is necessary to use scientific instruments and tools, accurately measure the content of formaldehyde, see ever exceeds bid, to take corresponding measures according to the results of the measurement.
