PAHs (polycyclic aromatic hydrocarbons, a carcinogen): Polycyclic aromatic hydrocarbons (PAHs) are hydrocarbons containing more than two benzene rings in molecules, including more than 150 compounds such as tea, anthracene and phenanthrene.

English full name Polycyclic Aromatic Hydrocarbons, referred to as PAHs.
The International Research Center for Cancer (IARC) (1976) lists 94 carcinogenic compounds in laboratory animals, 15 of which belong to polycyclic aromatic hydrocarbons. Because benzo [a] pyrene is the first environmental chemical carcinogen to be found and has strong carcinogenicity, benzo [a] pyrene is often used as the representative of polycyclic aromatics.
PAH in consumer goods mainly exists in the following aspects:
- Softening Oil for Rubber and Flexible Plastics
- Black dyes in rubber and plastics
- Paint
- Preservatives
The following eight polycyclic aromatic hydrocarbons (PAHs) are restricted by item 50 of Annex 17 of the EU REACH Directive to contain polycyclic aromatic hydrocarbons (PAHs) in tyres and oils.
According to the official resolution ZEK01-08 of ZLS (GS Authorization Agency), the certification of GS logo will be compulsory to join PAHs from April 1, 2008. Products that fail to meet PAHs requirements will not be able to obtain GS certificates.
Testing items (mg/kg) Category I, Category II, Category III, Food Contact Material, Material that can be placed in the mouth and toys for children under three years of age for more than 30 seconds of contact with skin, Material of Category I toys for less than 30 seconds of contact with skin or Material Benzo [a] pyrene benzopyrene which is not in contact with skin, shall not be detected (<0.2)*1201 Total 6 kinds of PAH can not be detected (<0.2)*10200
