Coal dust alters β-naphthoflavone-induced aryl hydrocarbon receptor nuclear translocation in alveolar type II cells

Table 1 The concentrations of different PAHs in CD.

PAH	Concentration (μg/mg CD)	Estimated Exposure per CD-exposed rat¹ (μg)
Phenanthrene	0.0300	1.200
Naphthalene	0.0139	0.556
Pyrene	0.0620	0.248
Fluoranthene	0.0580	0.232
Fluorene	0.0500	0.200
Total identifiable PAHs²	0.0605	2.436

¹CD-exposed rats in this study received 40 mg CD by IT instillation. The micrograms of PAH instilled represents the estimate concentration in the 40 mg of CD.
²In addition to be identified PAHs, multiple methyl substituted naphthalenes and phenanthrenes were identified. Theses could not be quantified because of an absence of matching standards. Other PAHs and substituted PAHs maybe present but were either not detected or the presence of interfering ions prevented unambiguous identification.
