There are two methods of decoration pollution detection First, self-testing, and testing organizations.

Formaldehyde, ammonia olfactory irritant, to some extent, with the smell can judge the degree of pollution. For example, formaldehyde exceeded 1 times, there will be a slight odor; exceeded five times, there will be obvious odor to be more than ten minutes on the nose, throat discomfort, itchy eyes; exceeded 20 times, will shed tears, pungent, cough; exceeded 20 times above, dyspnea, respiratory damage.

Second, we can use a commercially available indoor formaldehyde detector and air formaldehyde self-test box for testing. The self-test cartridge contains absorber (brown bottles), coloring agent (white bottle), the absorption box (white plastic boxes), colorimetric card, the manual five major product composition. Use is confined analyte space for one hour, followed by the absorbent into the suction box after shaking for 30 minutes in a confined space, and then color-developing agent was poured into the suction box, stand for 10 minutes sufficient reaction after the absorbent cartridge liquid color and contrast, colorimetric card read out the values ​​of the final concentration of formaldehyde. Once again, the law of animals and plants, leaf green plants indoor curling in a week, leaf edges yellowed and gradually wither the indoor formaldehyde exceeded 2 times. Finally, keep a small goldfish shallow basin, as death within a week, the indoor concentration of formaldehyde at least exceeded 3-5 times.

General fees of professional testing organizations test formaldehyde and benzene content can be 500 to 1000 yuan. Pre-test preparations, to be completed in the decoration of natural ventilation for seven days after the detection. Ammonia, formaldehyde, benzene, total volatile organic compounds TVOC concentrations detected, should be carried out immediately after the doors and windows closed one hour.

Detection of radon concentration should be outside the doors and windows close 24 hours after detection the day of the time required for a sample needs 30 minutes to twelve hours waiting for the test reports, test results takes about a week or so.
