Does "smelling peculiar smell" prove that there are pollutants in the room? For the public, how to effectively judge whether there is interior decoration pollution?
Experts say that people's nose, eyes and voice are more sensitive to indoor decoration pollution. If you smell peculiar smell in the room, you can basically judge that there are pollutants. However, this does not mean that the pollutant content must exceed the standard. After decoration, some peculiar smell in the new house can be dissipated in a short period of time. It is not strict to judge whether the pollution exceeds the standard by nose. Some pollutants are colorless and tasteless, but "smellless" does not mean that there is no indoor air pollution.
Speak with data. Some consumers are willing to buy their own testing instruments.
However, Zhang Yinping said, "the accuracy of most low-cost small VOCs detection equipment is low, but we can refer to the trend and relative value of pollutant concentration to make a preliminary judgment on indoor decoration pollution."
Special third-party indoor air testing institutions are the most reliable for door-to-door testing. Special attention should be paid to ensure that the organization has passed the metrological certification of the quality and technical supervision department at or above the provincial level.
Only reports issued by such institutions have legal effect. You can ask the organization to issue the measurement certification (CMA) certificate and the inspection capacity table before the entrusted test.
Why is the test result qualified, and still some people feel uncomfortable?
Individual sensitivity is different. In the same indoor space, some people feel peculiar smell, while others don't.
And a single piece of furniture, building materials or a single room testing does not mean that all together on the whole qualified. In addition, the detection conditions do not exceed the standard, and can not guarantee that all conditions of use do not exceed the standard.
The national standard "indoor air quality standard", which is often used as the basis for testing, was established in 2002. Now some details need to be updated.
