| Short description: |
This review report concerns the assessment of both known and atypical sources of soil contamination with tars with special reference to benzo(a)pyrene (BaP). Tar constituents are not easily degraded, are frequently identified in connection with soil investigations and some (BaP) are carcinogens.

| Long description: |
A description of the physical and chemical properties, degradation and the effects on the environment and health are given for PAH. The significance of benzo(a)pyren for risk assessments is explained and related to the history of development for soil quality criteria for PAH in Denmark. National soil quality criteria from other countries are quoted. PAH are found naturally in a range of fossil fuels such as coal and oil, and are released from them by heating. Incomplete combustion of all forms of organic material produces PAH. PAH loads in the environment can occur naturally due to forest fires, but especially due to human activities such as oil refining, tar distillation, asphalt production, waste incineration, the former production of town gas and storage of fuels, as well as emission from transport, heating, and industry (cars, lorries, planes, trains, power stations, wood burning stoves, etc.). It is estimated that background levels in rural Danish soils are less than 0.05 – 0.1 mg total PAH/kg, while soils in urban areas have a much higher “background level”. PAH profiles for oil products, tars, exhaust from cars and combustion of wood vary considerably, but contaminated soils show relatively similar PAH profiles regardless of source.
