  1. JSPS Multilateral Cooperative Research Programme “Coastal Marine Science” Melaka, 19 – 20 May 2008 Spatial Distribution and Sources of Polycyclic Aromatic Hydrocarbons (PAHs) in Different Soft Tissues of Green Mussels (Pernaviridis) from Tebrau Straits, Peninsular Malaysia Mohamad Pauzi Zakaria, Ph.D CheAbd.

  2. Biomonitoring of Pollutants using Mussels

  3. Advantages of Using Mussels as Sentinel Organisms ･ Cosmopolitan and widely distributed throughout the world. ･ Sedentary and better representative of the study area than mobile species. ･ Mussels accumulate contaminants by factors of 102 - 105 compared to seawater in their habitat. ･ High tolerance to pollution. ･ low or undetectable activity of enzyme systems that metabolize many xenobiotics. ･ Stable local populations. ･ Reasonable size for analysis. ･ Commercially valuable seafood species on a worldwide basis.

  4. JOHOR BHARU Kg. Pasir Puteh Singapore Sampling Locations

  5. PAHs fingerprinting in different tissues of green mussels (P.viridis)

  6. Total PAHs in different Soft tissues and hard tissues of P.viridis

  7. PAHs fingerprinting in different tissues of green mussels (P.viridis)

  8. Relative distribution of LMW PAHs

  9. Diagnostic Ratio using Perylene/penta-aromatic isomers • The concentrations of perylene relative to the penta-aromatic isomers were calculated for the tissues of mussels collected from coastal waters of PasirPuteh which characterized by a low abundance of perylene relative to the penta-aromatics. • Therefore it can be concluded that low abundance of peryleneindicating a probable pyrogenic origin in different tissues

  10. Conclusions • PAHs concentrations in the different soft tissues of p. viridis were accumulated mainly in the lipids • Gonad and gills of p. viridis as biomonitors of bioavailability and contamination of PAHs in semi-enclosed waters and bays • The ratios of methylphenanthrenes to phenanthrene and perylene to penta-aromatic ratios indicate that Tebrau Straits suffer widespread input of petrogenic PAHs along Tebrau Straits.
