What is PAHs Testing?

Views :
Update time : 2025-01-08

PAHs (Polycyclic Aromatic Hydrocarbons) refer to a class of organic compounds containing two or more benzene rings. These compounds, including over 150 types such as naphthalene, anthracene, phenanthrene, and pyrene, are hydrocarbons with two or more fused benzene rings. Some PAHs also contain nitrogen, sulfur, or cyclopentane. Many PAHs, particularly those with four to six fused rings, are known to be carcinogenic. The International Agency for Research on Cancer (IARC) identified 94 compounds as carcinogenic to laboratory animals in 1976, 15 of which are PAHs. Benzo[a]pyrene, the first identified environmental chemical carcinogen, is often used as a representative of PAHs and constitutes 1%–20% of all carcinogenic PAHs.

Health Risks of PAHs

PAHs primarily affect the respiratory system and skin. Prolonged exposure to PAH-contaminated environments can cause acute or chronic health issues, including:

- Photosensitive dermatitis

- Acne-like dermatitis

- Folliculitis

- Wart-like growths

 

Regulatory Framework

Global Standards

Numerous international regulations govern PAHs, including:

- REACH Annex XVII (European Union)

- German GS Certification and LFGB

- U.S. EPA

- China GB Standards

 

European Union

On December 7, 2013, regulation (EU) No. 1272/2013 amended REACH Annex XVII to extend PAHs restrictions to consumer goods. This regulation took effect on December 27, 2015.

 

Germany

Germany has enforced PAHs control for GS-certified products since April 1, 2008. The German Technical Equipment and Consumer Products Committee (AtAV) mandates compliance with the 16 PAHs specified by the U.S. EPA. In 2011, Germany released ZEK01.4-08, updating PAHs testing requirements to include benzo[j]fluoranthene and benzo[e]pyrene, expanding the controlled list to 18 compounds. This update became effective on July 1, 2012. Subsequently, the German Product Safety Committee (AfPs) issued revised PAHs requirements for gs certification, effective July 1, 2015.

 

PAHs in Materials

PAHs are commonly found in:

- Charcoal

- Petrochemical products

- Pharmaceuticals

- Dyes

- Plastics and rubbers

- Pesticides

- Lubricating oils and rust-proofing agents

- De-molding agents

- Electrolytes in capacitors

- Insecticides, fungicides, mosquito coils

- Cigarettes

- Gasoline stabilizers

- Other incomplete combustion products

 

Testing Process

1. Consultation: The applicant provides product information and descriptions.

2. Quotation: Technical engineers assess the project and provide a cost estimate.

3. Acceptance: The applicant approves the quote.

4. Submission: The applicant submits a testing application form along with samples.

5. Testing: Laboratory tests are conducted following applicable standards.

6. Report: A detailed testing report is issued.

7. Certification: A compliance certificate is issued for passing products.

The main 18 PAHs include:

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
