Zusammenfassung: | Provided is a petroleum-based aromatics-containing oil having a saturates content by the clay-gel method of not more than 40 mass%, a proportion for a bicyclic aromatics fraction, as fractionated using HPLC, of 10 mass% to 30 mass% with reference to 100 mass% for an aromatics fraction, a benzo(a)pyrene content of not more than 1 mass-ppm, and a total content of following specific aromatic compounds 1) through 8) of not more 10 mass-ppm: 1) benzo(a)pyrene, 2) benzo(e)pyrene, 3) benzo(a)anthracene, 4) chrysene, 5) benzo(b)fluoranthene, 6) benzo(j)fluoranthene, 7) benzo(k)fluoranthene, and 8) dibenzo(a, h)anthracene. |
