最近在装修,翻了些相关帖子,收集到的一些资料
1。物品的甲醛排放标准(排放标准:E0,1,2,的这种,每个国家的E标准都不一样,对不同物品要求也不一样)和室内空气的甲醛含量标准是两个标准,测试方法不一样。
物品甲醛排放的测试过程很复杂,个人几乎没法测
2。测试仪通常用来测空气里的甲醛含量,但是准确度低,没法校准的情况下读数误差很大,参考价值低(也就是读数偏高需要开窗这样的参考)
看了下楼上提到的gov的网站,上面有一个NICNAS Priority Existing Chemical Assessment Report No. 28 – Formaldehyde.
(另外,单位换算用:甲醛 at 25 °C, 1 ppm = 1.228 mg/m3)
1。 研究显示,空气中甲醛含量小于0.2 ppm = 0.246 mg/m3时,致癌风险很低
formaldehyde levels at the majority of workplaces are less than 0.2 parts per million (ppm), and the nasal cancer risk is very low at these levels
2。澳洲政府对室内环境甲醛含量的建议值 80 ppb = 0.08 ppm = 0.098 mg/m3 (等于大陆对室内环境的强制国标)
NICNAS recommends an indoor air guidance value of 80 ppb
3。澳洲政府对职业暴露的国家标准:1 ppm = 1.228 mg/m3
The current national occupational exposure standard for formaldehyde is 1 part per million (ppm)
其他地方看到的
1。甲醛在自然环境中的含量在0.03 ppm = 0.037 mg/m3 到 0.08 ppm = 0.098 mg/m3(市区)之间。(http://www.abcb.gov.au/-/media/Files/Resources/Education-Training/11HandbookIndoorAirQuality2018.pdf)
Formaldehyde is present in the outdoor air at natural background levels of about 0.03 ppm with concentrations up to 0.08 ppm in outdoor urban air。
2。澳洲对非工作场合的室内空气质量没有强制标准(https://www.environment.gov.au/protection/air-quality/indoor-air)
In contrast to the USA, Australia currently has no specific controls on indoor air quality - apart from workplace situations under the National Occupational Health and Safety Commission |
