。。。建议MM买个空气过滤器放在你的bench边上，平时带口罩 |

外界干扰的。 |

1）其实是俺老婆的办公室，她老板听说了很重视，明天学校会来人，测一个周末。
2）我们买的实际上是西夫试剂，吸收空气中的醛类变成紫红色，但如果吸收的时甲醛
，滴入浓硫酸会退色，其他醛类不会。
3）昨天我们试了硫酸，退色了。。。
4）但是办公室的确有奇怪的味道，包括她老板的办公室。

发帖数: 194 | 13 Convert 0.6mg/m3 to ppm, it is about 0.48 ppm. That is way too high. Did you
feel any discomfort of your throat or nose?
The U.S. EPA and T American Lung Association recommend a maximum level of 0.
1 ppm for formaldehyde in indoor air. Because some people may be sensitive
to lower concentrations, the Agency for Toxic Substance and Disease Registry
has recommended
Minimum Risk Levels (MRL's) that depend on the duration of personal exposure.
Below the MRL, there are no significant health effects in most people.
MRL=0.04ppm (1 to 14 days exposure)
MRL=0.03 ppm (14 to 364 days exposure)
MRL=0.008 ppm (365 or more days exposure)
You can buy much sensitive kit from Advanced Chemical Sensors and you could
get the result within a week. A little bit expensive than your test kit,
which cost about 30 bucks. However, the result is very accurate, which could
give you 0.00X ppm limit.
Hope it will help you. |

My wife's nose was not pleasant for a while, but that is also her old
problem. Other guys in her office did not have obvious discomfort, but
everybody said they had some headache or cough after hearing the test result.
No body reported discomfort of throat or eyes, but every one can smell the
strange odor.
