Non-Target Screening Method for the Identification of Persistent and Emerging Organic Contaminants in Seafood and Sediment from Jakarta Bay
Abstract: Identification of
persistent and emerging organic contaminants in green mussels (Perna viridis),
various fishes, banana shrimp (Penaeus merguiensis) and sediment samples from
Jakarta Bay has been employed. A non-target GC-MS screening approach has
identified more than 60 individual organic compounds from the whole fractions
either non-polar, semi-polar or acidic-polar compounds. The substances
comprised as persistent organic pollutants (POPs) including DDT
(dichlorodiphenyl trichloroethane) and its metabolites as well as high
molecular weight polycyclic aromatic hydrocarbons (HMW-PAHs). Noteworthy, a
number of emerging contaminants detected in the present study have never been
reported previously either from the same location or from Asian waters. They
include some priority contaminants of non-persistence halogens and emission of
technical products, such as di-iso-propylnaphthalenes (DIPNs) dichlorobenzene
(DCB), dichlorodiphenyl chloroethene (DDMU) and phenylmethoxynaphthalene (PMN).
In general, the concentration order of the priority organic contaminants was
sediment > green mussel > fishes > shrimp. Further analysis based on
the spatial distribution, individual concentrations and bioavailability
suggested that some contaminants are applicable as molecular marker for the
assessment of anthropogenic emission in Jakarta Bay, i.e. DIPNs, linear alkylbenzenes
(LABs), phenylmethoxynaphthalene (PMN), PAHs, dichlorobenzene, DDT and its
metabolites.
