A benzopyrene is an organic compound with the formula C20H12. Structurally speaking, the colorless isomers of benzopyrene are pentacyclic hydrocarbons and are fusion products of pyrene and a phenylene group. Two isomeric species of benzopyrene are benzo[a]pyrene and the less common benzo[e]pyrene. They belong to the chemical class of polycyclic aromatic hydrocarbons.

  • I benzopireni sono idrocarburi (formula molecolare C20H12) della serie aromatica, policiclici a cinque anelli benzenici condensati. Strutturalmente parlando, essi sono formati da un pirene condensato con un gruppo fenile. I due isomeri più comuni sono il benzo[a]pirene e il meno comune . (it)
  • Benzopireno refere-se a dois hidrocarbonetos aromáticos policíclicos isômeros, formados pela fusão de cinco anéis: benzo(a)pireno e . É um potente agente cancerígeno e mutagênico, o que significa que ele reage com o DNA humano, interferindo na reprodução das células e acaba afetando muito as áreas atingidas. O benzopireno está presente na fumaça de cigarros, carvão (sobre carnes assadas ou carnes e peixes defumados), e também na atmosfera das grandes cidades. Formula Molecular: C20 H12 (pt)
  • 苯并芘(英語:Benzopyrene)是苯与芘而成的一类多环芳香烃。根据稠合的位置不同,可以有苯并[a]芘和苯并[e]芘等多种异构体,这些名称来源于IUPAC命名法中对芘分子环中各化学键的编号(见右图)。 最常见的苯并芘是苯并[a]芘。它是一种致癌物质和突变原。 (zh)
  • Els benzopirens, en anglès: benzopyrenes, són uns compostos orgànics, classificats com a hidrocarburs aromàtics policíclics i que tenen fórmula C20H12. Hi ha dues formes isomèriques de benzopirens: * benzo[a]pirè * . (ca)
  • Benzopireny, C20H12 – dwa organiczne związki chemiczne z grupy wielopierścieniowych węglowodorów aromatycznych. Zbudowane są z pięciu skondensowanych pierścieni benzenowych. Zawierają czteropierścieniowy szkielet pirenu z dołączonym dodatkowym pierścieniem benzenowym. Możliwe są dwa izomery strukturalne, różniące się miejscem przyłączenia pierścienia benzenowego do pirenu. Duża ilość benzopirenów, ok. 1,5%, znajduje się w smole pogazowej. (pl)

  • Els benzopirens, en anglès: benzopyrenes, són uns compostos orgànics, classificats com a hidrocarburs aromàtics policíclics i que tenen fórmula C20H12. Hi ha dues formes isomèriques de benzopirens: * benzo[a]pirè * . Els benzopirens són problemàtics per la seva intercalació amb l'ADN que interfereix en la transcripció genètica. Es consideren contaminants i carcinògens. Són emesos de manera natural pels incendis forestals i erupcions volcàniques, tot i que també es pot trobar al quitrà d'hulla, fum de cigarretes, les males combustions, menjars torrats com ara el cafè, o productes com l'oli de pinyolada d'oliva.
