ABSTRACT
We used the brown alga Padina boryanawas to determine polyromantic hydrocarbons (PAHs)
bioaccumulation at a Jeddah City seashore. We also measured PAHs in the coastal water and in algal tissues
using gas chromatography mass spectrometry (GC-MS).
Acenaphthene (Ace) and dibenzo(a,h)anthrancene (dB(a,h)An) were the main PAHs in sea water (50.02 and 46.18 ng l-1, respectively) and in algal tissues (64.67 and 72.45ng g-1, respectively), respectively. The ratios of low molecular weight/high molecular weight hydrocarbons (1.76-1.44), fluoranthene/pyrene (1.57-1.52), and phenanthrene/anthracene (0.86-0.67) in seawater and algal tissues indicated the origin of PAHs to be mainly pyrogenic.
The high concentrations of PAHs in algal tissues demonstrated the utility of using Padina boryana as a biomonitor of PAH contamination and bioavailability in the coastal waters.
