Environmental Levels and Human Exposure. Aluminium may be designated as crustal in origin, and thus surface soils at uncontaminated sites constitute a source of soluble aluminium species in surface water and aluminium-containing particulates in sediments and ambient-air aerosols.
Cited by: 9522012-3-1€ang et al. (2003) compared several diagnostic ratios for assessing the pyrolytic and petrogenic origins of PAHs in harbour sediments. The FLA/ (FLA + PYR) ratio was found to be a poor indicator of pyrolytic and petrogenic activities, whereas BaA/ (BaA + CHR) was a good indicator of pyrolytic pollution emission sources.
