PAHS

Chemical testing

PAHs, Scientific name: polycyclic aromatic hydrocarbons. It is a type of harmful substance produced by incomplete combustion or high-temperature treatment of fuels such as petroleum, coal, wood, and combustible gases. It usually exists in petrochemical products, rubber, plastics, lubricants, rust proof oils, incomplete combustion organic compounds, and other substances. It is one of the important carcinogens in the environment  
In the environment, organic pollutants are ubiquitous, with polycyclic aromatic compounds (PAHs) being the majority, and some have been proven to be carcinogenic and mutagenic to humans. There are over 100 known PAHs, and 16 PAHs are regulated by the US Environmental Protection Agency

The German Safety Technology Certification Center requires mandatory inclusion of PAHs testing in GS mark certification, which came into effect on April 1, 2008

PAHs mainly include the following 16 similar substances:

1 Naphthalene 萘 

2 Acenaphthylene 苊烯 

3 Acenaphthene 苊 

4 Fluorene 芴 

5 Phenanthrene 菲 

6 Anthracene 蒽 

7 Fluoranthene 荧蒽 

8 Pyrene 芘 

9 Benzo(a)anthracene 苯并( a )蒽 

10 Chrysene 屈 

11 Benzo(b)fluoranthene 苯并( b )荧蒽 

12 Benzo(k)fluoranthene 苯并 (k) 荧蒽 

13 Benzo(a)pyrene 苯并( a )芘 

14 Indeno(1,2,3-cd)pyrene 茚苯( 1,2,3-cd )芘 

15 Dibenzo(a,h)anthracene 二苯并( a, n )蒽 

16 Benzo(g,hi)perylene 苯并( ghi )北(二萘嵌苯)
