Polycyclic Aromatic Hydrocarbons PAHs are hydrocarbon compounds formed by two or more interconnection aromatic, it’s produced by slow and incomplete combustion of organic compounds or pyrolysis of organic compounds under high-temperature.

Now there are more than 100 kinds of chemical formula are founded and among which, more than 30 kinds are confirmed to be carcinogenic, 18 species are listed as priorities by the U.S. EPA assessment.

PAHs may exist in the following materials:

- charcoal, oil, creosote, tar natural

- drugs, dyes, plastics, rubber, pesticides human made

- lubricant, releasing agent, capacitor electrolyte, mineral oil, tar human made

- insecticides, fungicides, mosquito coils, smoke, gas condensate blocking agent human made

- Others

Hazards of PAHs:

- strong carcinogen

- damage the reproductive system

- easily lead to skin cancer, lung cancer, upper gastrointestinal cancer, arteriosclerosis, infertility

Regulatory requirements of PAHs:

- EU 76/769/EEC Germany:

- GS certification, LFGB

- the United States: EPA

- Chinese: GB, GB / T, GHZ.

The German government mandatory regulation requires all the PAHs related products have to be tested whether they contained excessive PAHs before selling to Germany.

After the discussion between ALDI Süd and ALDI Nord, Germany sets the limit amount of PAHs as follows:

- Class One: materials which touch food or goods and toys which may be placed in the mouth of children under three years old

BaP: not detected * <0.2 mg / kg, the total amount of 16 items of PAHs: not detected * <0.2 mg / kg

- Class Two: plastic parts which have frequent contact with skin and the contact time is more than 30 seconds, toys that are not regulated in Class One

BaP:1 mg/kg ,the total amount of 16 items of PAHs: 10 mg/kg

- Class Three: plastic components which have occasional contact with skin and the contact time is less than 30 seconds or parts that have no contact with skin

BaP:20mg/kg,the total amount of 16 items of PAHs:200 mg/kg

If the test results is lager than Class One and meet Class Two, then the products should be tested for the migration test to confirm the test results according to DIN EN1186 64 LFBG80.30-1.
