“…Al-aziziyah, in southern Dammam city (S2), receives continuous disposals from urban drainages (Zyadah and Almoteiry, 2012). The Al-Jubail coast (S3) is affected by effluents from the largest industrial complex in Saudi Arabia containing sewage and desalination plants (Alkhalifa et al, 2012; El-Sorogy and Youssef, 2015) and is contaminated with a mixture of oil products and heavy metals. According to Joydas et al (2012), Manifa (S4) on the northern Saudi shoreline has been subjected to severe impacts from oil industries.…”

In this field study, the levels of heavy metals (Pb, Fe, Co, Cu, and Zn) in water and a suite of biochemical and histological biomarkers in the grouper ( Epinephelus tauvina) were assessed at four sites in the Arabian Gulf. Samples were taken from a relatively non-urban reference site, called Salwa (S1), and three effluent-dominated sites, namely Al-aziziyah in southern Dammam city (S2), the Al-Jubail coast (S3), and Manifa (S4). Toxic metals, namely Pb and Co (at all sites) and Fe (at S3), were elevated in water samples relative to the internationally permissible limits. In fish, induced levels of heat shock protein 70 (HSP70) in the liver at S3 and S4 were higher than those of the reference fish at S1. Additionally, the level of the lipid peroxidation (LPO) product (malondialdehyde (MDA)) was significantly increased in gills (at S3) and liver (at S2 and S3). There was an inhibition of catalase activities in the gills of fish from S2 to S4 and significantly higher activity levels of superoxide dismutase in the gills of fish from S4. Histopathological features such as aneurysms in gill vessels, deformed gill lamellae, increases in liver melano-macrophage centers, and hepatocellular necrosis were most abundant at sites where significant pollution problems exist (i.e. S2-S4). The results reveal that the eastern coast of Saudi Arabia, in the Arabian Gulf, is still contaminated, as indicated by elevated HSP70, LPO content and numbers of histological lesions, and that monitoring of contaminants and their effects should be continued in this region.

“…Bivalves' soft tissues, rather than shells, were more popular among researchers in metal bioaccumulation studies [16]. Despite less involvement, trace metal assessment in bivalves' shells was widely accepted and applied in aquatic ecosystem monitoring [17][18][19]. However, short-term laboratory treatments indicated that bivalve's shells could be less suitable for metal detection due to a slower accumulation rate in comparison with the soft tissues [20].…”

Shell Organic Matrix (Conchix) of the Mediterranean Mussel Mytilus galloprovincialis L. as the Medium for Assessment of Trace Metals in the Boka Kotorska Bay

et al. 2023

The content of trace metals, namely Zn, Cu, Fe, Mn, Pb, Cd, and Hg, in four types of media, i.e., soft tissues, shells, and the products of shell demineralization (organic matrix—conchix and extract) of the Mediterranean mussel Mytilus galloprovicialis L., at three sites in the Boka Kotorska Bay of the Adriatic Sea were determined. The main aim was to investigate the accumulation patterns of trace metals in conchix and their possible relationship with other tested media. Conchix weight within a group of mussels from Sv. Nedjelja was significantly higher in comparison with the IMB, while conchix % in the shell showed a negative correlation with dry shell weight. The highest metal pollution index (MPI) values found in the soft tissues of mussels from Sv. Nedjelja, Cogi, and the IMB were 2.319, 2.711, and 2.929 µg g−1, respectively. PCA analysis showed similarities in trace metal accumulation in all media except conchix. According to CCA analysis, conchixes were grouped around Cu, Fe, and Hg, while Cd and Zn were in correlation with the soft tissues. Moreover, the shells were in correlation with Mn. Simple isolation with high yield, close contact to the environment in comparison with calcified shell layers, and susceptibility to possible pollution sources due to the accumulation of specific metals are the main reasons to consider conchix of M. galloprovincialis as a medium with potential in trace metal assessments of marine ecosystems.

“…Intensive anthropogenic activities in recent decades accelerate the elevation of pollutants (El-Sorogy and Youssef, 2015;Rahman and Singh, 2016). Metals become one type of the hazardous pollutants in an environment due to their persistence, recalcitrance, toxicity and bioaccumulation properties (Kang et al, 2015;Li et al, 2013).…”

Suspended Particulate Matter (SPM) is an important compartment within water column due to its capability in adsorbing pollutant like heavy metals. However, there was limited information regarding SPM and its heavy metals content in Jakarta Bay. Therefore, this study was proposed to understand the spatial distribution, source and to assess metal content in SPM in Jakarta Bay. The samples were collected from 24 stations in April 2011 and were then analyzed using acid digestion processes adopted from USEPA 3050b. The generated data were then modeled to determine the spatial distribution of metals in SPM. The result revealed that the concentration of Cd, Cu, Ni, Pb and Zn in SPM were as follow: 10-110; 21-472; 14-356; 7-107; 87-4255 mg.kg-1, respectively. Since Cd, Pb and Zn in SPM were majorly concentrated in the area closed to harboring activities, the activities was suspected in contributing of high input of those metals, meanwhile, Cu and Ni was mostly came from riverine runoff. The computation of Index of Geoaccumulation (Igeo) revealed that the major area in Jakarta Bay was unpolluted by Cu, Pb, Zn, and Ni in SPM however 96% of the selected area were strongly contaminated by Cd in SPM. Thus, this study emphasized that harbor area as a dominant source of metals in SPM in Jakarta Bay and required to be well managed.Keywords: Jakarta Bay, Suspended Particulate Matter, heavy metals, contamination.Materi Partikulat Tersuspensi (SPM) merupakan bagian penting dalam kolom air karena kemampuannya dalam menjerat polutan seperti logam berat. Akan tetapi, informasi mengenai SPM dan kandungan logam berat dalam SPM di Teluk Jakarta terbatas. Oleh karena itu, tujuan dari studi ini adalah untuk mengetahui distribusi spasial, dan sumber logam berat serta menilai kualitas lingkungan berdasar kandungan logam berat dalam SPM di Teluk Jakarta. Sampel SPM diambil dari 24 titik observasi pada bulan April 2011 kemudian dianalisis dengan proses digestif asam yang diadopsi dari USEPA 3050b. Data yang didapat kemudian dimodelkan untuk mengetahui distribusi spasial logam berat dalam SPM. Hasil analisis menunjukkan bahwa konsentrasi Cd, Cu, Ni, Pb dan Zn dalam SPM secara berurutan sebagai berikut: 10-110; 21-472; 14-356; 7-107; 87-4255 mg.kg-1. Cd, Pb dan Zn lebih ditengarai bersumber dari aktivitas pelabuhan karena konsentrasi Cd, Pb dan Zn di area tersebut tinggi sementara Cu dan Ni lebih banyak berasal dari limpasan sungai. Perhitungan Indeks Geoakumulasi (Igeo) menunjukkan bahwa sebagian besar area tidak tercemar oleh Cu, Pb, Zn dan Ni akan tetapi 96% area teramati tercemar Cd. Oleh karena itu, studi ini menyarankan untuk ditingkatkannya manajemen pembuangan limbah di pelabuhan sebagai sumber logam.Kata kunci: Teluk Jakarta, Materi Partikulat Tersuspensi, logam berat, pencemaran.
