PAHs Directive(2005/69/EC)

    European parliament and EU council had signed 2005/69/EC Directive at France Strasbourg on Nov 16th, 2005, and had been published on Dec 9th, 2005.
The main content of this directive:
    Its application scope is accession oil and vehicle tire (passenger car tire, light and heavy truck tire, farming vehicle tire and motorcycle tire). Directive will also be effective to tires produced or renewed after Jan 1st, 2010.
Directive stipulates accession oils put into market directly or used for tire manufacturing should meet following technical specifications: Benzo pyrene(BaP) content should be less than 1mg/kg; at the same time, the total content of 8 PaHs(BaP, BeP, BaA, CHR, BbFA, BjFA, BkFA, DBAh) should be less than 10mg/kg.
    This kind of testing method will be set by European Committee for Standardization (CEN) or International Organization for Standardization (ISO). This directive also requires: EU member countries must set related law, stipulation or management documents before Dec 29th, 2006. Its planned effective date should be Jan 1st, 2010.
The main components of polycyclic aromatic hydrocarbons 
    Polycyclic aromatic hydrocarbons main (PAHs) to the 18 kinds of compounds: naphthalene, acenaphthylene, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene, pyrene, benzo (a) anthracene, Qu, benzo (b) fluoranthene, Benzo (k) fluoranthene, benzo (a) pyrene, indeno (1,2,3-cd) pyrene, dibenzo (a, h) anthracene and benzo (g, h, i) perylene, 1 - A Kenai, 2 - A Kenai. 
    The current set of 16 PAHs of similar substances commonly include:

Naphthalene Benzo(a)anthracene
Benzo(a)anthracene Chrysene lettuce
Acenaphthene  Acenaphthylene   Benzo(b)fluoranthene
Fluorene  Benzo(k)fluoranthene
Phenanthrene Philippines    Benzo (a) pyrene
Anthracene    Indeno(1,2,3-cd)pyrene indeno benzene (1,2,3-cd) pyrene
Fluoranthene  Dibenzo(a,h)anthracene Dibenzo (a, n) anthracene
 Pyrene   Benzo (g, hi) perylene Benzo (ghi) North (perylene )

The main usage of polycyclic aromatic hydrocarbon:
    Polycyclic aromatic hydrocarbon exists in petrochemicals, such as crude oil, creosote, dye, plastic, rubber, lubricating oil, rust preventive oil, release agent, gas anti coagulant, capacitance electrolyte, mineral oil, asphalt, etc; also exists in daily chemical products, such as pesticide, carboligni, fungicide, mosquito-repellent incense, etc.
    In the electrical and electronic manufacturing industry, PAHs is usually used as plastic additive in producing processes, for example, while extruding plastic particles, plastic particles are usually adhibited with mould, at this time, it is needed to add release agent, but release agent may contain PAHs.
