Polycyclic aromatic hydrocarbons (PAHs) are a class of chemicals that occur naturally when coal, crude oil, and gasoline are burned. These chemical compounds are also produced when coal, oil, gas, wood, garbage and tobacco are burned.

PAHs produced from these sources form or bind to small particles in the air. PAHs are also formed in meat and other foods during high temperature cooking. Cigarette smoke contains many polycyclic aromatic hydrocarbons.
People are exposed to PAHs in many settings. For example, breathing air polluted by motor vehicle exhaust, cigarette smoke, wood smoke or fumes from asphalt roads is the most basic form of exposure. PAHs enter the human body by ingestion, inhalation or through the skin. These are generally excreted from the body through urine and feces.
The effects of low levels of environmental PAH exposure on human health are not fully known. However, intense PAH exposure can irritate the respiratory tract. Some mixtures of PAHs are known to cause cancer.
The health effects of exposure to PAHs depend on:
These effects can be short-term or long-term.
The U.S. Environmental Protection Agency (EPA) has set maximum pollutant levels for water supplies to reduce the risk of adverse health effects from drinking contaminated water. These standards are much lower than the levels at which health effects are observed.
The set limit value is 0,2 parts per billion for total PAHs. There is no regulation for the PAH content of foods. PAH levels have also been determined for European Union countries.
To determine the level of PAH in the human body, blood or urine tests are performed. These tests only confirm exposure to PAHs, but the potential health effects are not detected. In addition, these tests require special equipment.
It is necessary to analyze the presence and concentrations of PAHs in different products. Various methods such as GC-MS (gas chromatography-mass spectrometry) and HPLC (high performance liquid chromatography) are applied in PAH analysis.
Our organization also provides polycyclic aromatic hydrocarbons (PAHs) testing services with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors.
