PAHS

PAHs, scientific name PAHs. Oil, coal and other fuels and wood, flammable gases in the incomplete combustion or heat treatment conditions in a class generated by harmful substances commonly found in petroleum products, rubber, plastics, lubricants, anti-rust oil, incomplete combustion organic compounds and other substances in the environment is one of the important carcinogens.
European Parliament and the European Commission on November 16, 2005 in Strasbourg, France signed the Directive 2005/69/EC and in the same year on December 9 release. This instruction focuses tires and add oil polycyclic aromatic hydrocarbons (PAHs) give directions.
April 1, 2008 German Security Technology Certification Center ZLS (GS authority) an official resolution ZEK 01-08 File: GS mark certification requirements will be forced to join PAHs, PAHs can not meet the requirements of the product will not get the GS certificate. All GS issuing bodies must perform this resolution.

Incomplete combustion of organic matter, coal / oil / gas / Tobacco / grill / charcoal, oil, creosote, tar, drugs, dyes, plastics, rubber, pesticides, engines, generators generate PAHs oil, coal and other fuels and wood, combustible gases in the incomplete combustion or heat treatment conditions in a class generated by harmful substances commonly found in petroleum products, rubber, plastics, lubricants, anti-rust oil, incomplete combustion of organic compounds and other substances in the environment in important carcinogens.
In the environment, organic pollutants in various polycyclic aromatic compounds (PAH) to its bulk, and some have been shown to be carcinogenic and mutagenic to humans. Sources of PAH include: algae or bacteria biosynthesis, forest fires, volcanic eruptions, as well as thermal power plants, incineration of garbage dump site, steam locomotive with the factory exhaust. Many different types of PAH, of which 16 kinds of compounds in 1979 by the U.S. Environmental Protection Agency (US EPA) listed in the tube. Polycyclic aromatic hydrocarbons may exist Material: charcoal, oil, creosote, tar (natural) medicines, dyes, plastics, rubber, pesticides (artificial) lubricants, release agents, capacitor electrolyte, mineral oil, asphalt (artificially ) insecticides, fungicides, mosquito coils, smoke, gasoline resistance coagulant (man-made).

Polycyclic aromatic hydrocarbons hazards
1, strong carcinogen
2, damage the reproductive system
3, easy to cause skin cancer, lung cancer, upper gastrointestinal cancer, arteriosclerosis, infertility
 
For background
Recently, China's production of a large number of power tools in Germany PAHs were detected value is exceeded, more than 80 million U.S. dollars worth of goods detained by German customs at the port. Germany is one of the core EU member states, so their influence soon spread to the entire European Union. Meanwhile, the EU technical standards mostly from Germany, once the new standards established PAHs, Britain, France, and even the United States will follow up to that time, Chinese enterprises exporting power tools and development will face more severe challenges.

PAHs mainly includes the following 16 kinds of similar substances:
1 Naphthalene
2 Acenaphthylene
3 Acenaphthene
4 Fluorene
5 Phenanthrene
6 Anthracene
7 Fluoranthene
8 Pyrene
9 Benzo(a)anthracene
10 Chrysene
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
Traits: pure PAH usually colorless, white, or pale green solid.
