What are PAHs polycyclic aromatic hydrocarbons?

Polycyclic aromatic hydrocarbons（ German:PolyzyklischerAromatischerKohlenwasserstoffe （PAK）/ English:PolycyclicAromaticHydrocarbons PAHs is the general term of more than 100 chemical structural formulas. PAHs contain 16 common polycyclic aromatic hydrocarbons.

PAHs are a kind of chemical substances formed by incomplete combustion of coal, oil, natural gas, wood, garbage or other organic matter. It can be used in plastics by extraction. At present, there are hundreds of different PAHs polycyclic aromatic hydrocarbons (including 16 PAHs polycyclic aromatic hydrocarbons). Some of these compounds, such as benzo (a) pyrene, are classified as carcinogens. Other species are also suspected to be carcinogenic. These substances may be found in coal tar, petroleum, plastics, rubber and dyes.

What are the sources of polycyclic aromatic hydrocarbons (PAHs)?

Incomplete combustion of organic matter, coal / oil / gas / tobacco / barbecue, charcoal, crude oil, creosote, tar, medicine, dye, plastic, rubber, pesticide, engine, generator;

What products (materials) may polycyclic aromatic hydrocarbons (PAHs) exist in?

At present, the known products that may obviously contain PAHs include: wire / plug, plastic handle, plastic packaging box, rubber handle, odorous plastic, rubber products, charcoal, crude oil, creosote, tar (NATURAL), medicine, dye, plastic, rubber, agricultural medicine (artificial), lubricating oil, film remover, capacitor electrolyte, mineral oil, asphalt (artificial) Insecticides, fungicides, mosquito repellent incense, smoking, gasoline retarder (artificial) and so on.

What are the hazards of polycyclic aromatic hydrocarbons (PAHs)?

PAHs is a kind of strong carcinogens, which can seriously damage the reproductive system, and easily lead to skin cancer, lung cancer, upper gastrointestinal cancer, arteriosclerosis, cardiovascular disease and infertility.
