Chrysene + Triphenylene

CHR+TRI; formula:C18H12; CAS Registry Number: 218-01-9 (CHR); 217-59-4 (TRI)

Polycyclic aromatic hydrocarbon with four connected six-membered rings

In the samples Chrysene and Triphenylen are analysed together as sum of both compounds.

Chrysene occurs in fossil fuels and is a product of incomplete combustion. It is used in the production of UV-filters, paints and sensitizers as well as in fluorescence labelling.

Emissions into the environment are mainly caused by human activities, e.g., coal combustion, gasification, exhausts of gasoline, diesel and kerosene engines, wood burning stoves, waste incineration and emissions from metal-working industries.
Chrysene is found in fruit and vegetable from areas with high atmospheric burdens and soil contamination, in smoked and charbroiled food, and in meat with high fat content.

In the atmosphere it is adsorbed to particles and enters soils and surface waters through wet and dry deposition. Degradation is slow and it accumulates in the environment. The bioaccumulation potential of chrysene is high.

Chrysene is mutagenic in laboratory test and is suspected to be carcinogenic.

Chrysene is one of 16 PAHs which were included in the U.S. EPA-list of Priority Pollutants and is on the EU-list of PAH recommended for monitoring.

Triphenylene occurs naturally in fossil fuels and can be extracted from coal tar. It is a ubiquitous product of incomplete combustion and is found, e.g., in exhausts from engines, tobacco smoke and food and water which have been exposed to exhausts.

In laboratory tests, triphenylene is mutagenic. Due to lack of data, carcinogenicity and other toxic effects can not be evaluated.

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.
