Web1.3 The large number of analytes in Tables 1 - 3 of this method makes testing difficult if all analytes are determined simultaneously. Therefore, it is necessar y to determine and perform quality control WebLower molecular weight PAHs also tend to be more volatile (i.e., have a higher vapour pressure) and more readily partition into air from pure water (i.e., have a higher Henry’s Law constant). For example, the vapour pressure and Henry’s Law constant of naphthalene are 8.5 x 10-2mm Hg and 4.83 x 10-4
Characterization of a phenanthrene-degrading methanogenic
Phenanthrene is a polycyclic aromatic hydrocarbon (PAH) with formula C14H10, consisting of three fused benzene rings. It is a colorless, crystal-like solid, but can also appear yellow.
