Abstract:
Hydrocarbon pollution in estuary area has attracts many attention due to it hazardous
properties of hydrocarbon. Estuary area is a productive area, thus we must keep it in
secure level. Thus monitoring the level of hydrocarbon level in estuary area has become a
concern. Some of component of hydrocarbon has demonstrates carcinogenic effect to
human body, especially polycyclic aromatic hydrocarbon (PAHs). Purpose of this study
is to determine the distribution of total aliphatic hydrocarbon (T AHs) and polycyclic
aromatic hydrocarbon (P AHs) at each 9 station and to determine its concentration.
Samples were collected using Ponar Grab, back to laboratory it was dried, undergoes
soxhlet extraction process, and then it fractionated, lastly samples from each stations
were injected into GC-FID. From station I to station 9 there are 3 species ofTAHs which
is n-Pentatriacontane, n-Nonatriacontane, dan n-Tetracontane while 2 species of P AHs
which is naphthalene dan acenaphthene are not found in Sungai Kuala Terengganu. For
TAHs identification, n-Heneicosane can be found in all 9 stations and its concentration is
varies from l.180ppb to 108.245ppb. For PAHs species that were present at every station
is pyrene and lndeno(l,2,3-cd)pyrene.
