Polycyclic aromatic hydrocarbon with four connected six-membered rings

Benz[a]anthracene is a rather common PAH in the environment. With its four aromatic rings it is relatively volatile.
Like other PAH it is a product of incomplete combustion. Benz[a]anthracene occurs mainly in charbroiled meat, cigarette smoke, and emissions from automobiles and industry. Foods and water may be contaminated upon exposure to exhausts.

The compound is very persistent in the environment and is accumulated by organisms. It is toxic and mutagenic. Furthermore, it is carcinogenic in animal experiments and suspected to be carcinogenic also to humans.

Benz[a]anthracene is one of 16 PAHs which were included in the list of Priority Pollutants by the U.S. EPA (EPA-list) and is on the EU-list of PAH recommended for monitoring.

Specimen

  • Common mussel species as invasive animal in rivers and lakes with high information level for water pollution
  • Fine insoluble mineral or organic particles in the water phase
  • One of the most important edible mussel species common in the North and Baltic Sea
  • A major primary producer in semi-natural and anthropogenic affected ecosystems.
  • A major primary producer in semi-natural and anthropogenic affected ecosystems.
  • A deciduous tree typical of ecosystems close to dense conurbations and an indicator for the characterisation of the immission situation during the vegetation period.
  • As the most dominant deciduous tree species in Central Europe, it plays a significant role in most nearly natural and also anthropogenically influenced forest ecosystems up to an altitude of 1100 m.
  • As an organism living at ground level, it is a major driver of the decomposition of organic material (e.g. plant litter).
  • As an organism living at ground level, it is a major driver of the decomposition of organic material (e.g. plant litter).
  • Soil is livelihood and biosphere for humans, animals, plants and soil organisms. All the substances brought in are transported, transformed and/or accumulated in the soil.
