产品介绍

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.
