Certification Content Summary
PAHs, scientific name polycyclic aromatic hydrocarbons. It is a kind of harmful substances produced by the incomplete combustion of petroleum, coal and other fuels, wood and combustible gases or under the condition of high temperature treatment. Among the organic compounds and other substances, it is one of the important carcinogens in the environment.
The European Parliament and the European Commission signed Directive 2005/69/EC on November 16, 2005 in Strasbourg, France and issued it on December 9 of the same year. The Directive focuses on polycyclic aromatic hydrocarbons (PAHs) in tires and added oils.
On April 1, 2008, the official resolution ZEK 01-08 of the German Safety Technology Certification Center ZLS (GS authorized agency): GS mark certification will be mandatory to join the requirements of PAHs, and products that cannot meet the requirements of PAHs will not be able to obtain GS certificates. All GS issuing bodies are required to implement this resolution.

In the environment, organic pollutants are everywhere, polycyclic aromatic compounds (PAH) are the bulk, and some of them have been proved to be carcinogenic and mutagenic to human body. Sources of PAH include: biosynthesis of algae or bacteria, forest fires, volcanic eruptions, as well as thermal power plants, garbage dump incinerators, motor vehicles and factory exhaust. There are many types of PAHs, among which 16 compounds were listed by the United States Environmental Protection Agency (US EPA) in 1979.
PAHs mainly include the following 16 similar substances:
1 Naphthalene
2 Acenaphthylene
3 Acenaphthene
4 Fluorene
5 Phenanthrene
6 Anthracene
7 Fluoranthene
8 Pyrene
9 Benzo(a)anthracene
10 Chrysene Que
11 Benzo(b)fluoranthene
12 Benzo(k)fluoranthene
13 Benzo(a)pyrene
14 Indeno(1,2,3-cd)pyrene
15 Dibenzo(a,h)anthracene
16 Benzo(g,hi)perylene
Properties: Pure PAH is usually colorless, white, or light yellow-green solid.
