Additional information

The range of approx. 60 % of wash oil ingredients (wash oil composite sample No. 5) is between 3.4 and 4.2 with the estimated average of 3.8. The examined components were naphthalene (11 – 13% w/w), 1-methylnaphthalene (7 – 9% w/w), 2-methylnaphthalene (17 – 20% w/w), biphenyl (5 – 6% w/w), fluorene (4 – 5% w/w), acenaphthene (13 – 15% w/w), and phenanthrene (ca. 2% w/w).
