Polycyclic aromatic hydrocarbons (PAHs) refer to a class of organic compounds with two or more benzene rings. PAHs are hydrocarbons containing more than two benzene rings in the molecule, including more than 150 compounds such as naphthalene, anthracene, phenanthrene, and pyrene. The full name is also known as polycyclic aromatichydrocarbons.
1. Introduction of EU PAHS certification
Polycyclic aromatic hydrocarbons (PAHs) refer to a class of organic compounds with two or more benzene rings. PAHs are hydrocarbons containing more than two benzene rings in the molecule, including more than 150 compounds such as naphthalene, anthracene, phenanthrene, and pyrene. The full name is also known as polycyclic aromatichydrocarbons. Among them, 15 are polycyclic aromatic hydrocarbons. Because benzo-a pyrene is the first discovered environmental chemical carcinogen and is highly carcinogenic, benzo (a) pyrene is often used as the representative of polycyclic aromatics, which accounts for all carcinogenicity. Sexual polycyclic aromatic hydrocarbons 1%-20%.
2. the importance of EU PAHS certification
According to the decision of the German Technical Equipment and Consumer Goods Committee (ATAV), for GS-certified products after April 1, 2008, 16 polycyclic aromatic hydrocarbons (PAHs) of concern to the US Environmental Protection Agency (EPA) must be tested to ensure compliance with the relevant For products that have been certified before April 1, 2008, a risk analysis against PAHS must be carried out within 1 year, and products that fail to meet the relevant regulations of PAH will be revoked.
3. PAHS certification test project
The main eighteen compounds of polycyclic aromatic hydrocarbons (PAHs) are: naphthalene, acenaphthene, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene, pyrene, benzo(a)anthracene, chrysanthemum, benzo(b)fluoranthene, benzene Do(k)fluoranthene, benzo(a)pyrene, indeno(1,2,3-cd)pyrene, dibenzo(a,h)anthracene and benzo(g,h,i)perylene, 1- Methyl Naphthalene, 2-Methyl Naphthalene.
