“…However, studies of ecological degradation of the natural coastal wetlands has mainly considered impacts from local or coastal regions 12 , 37 , 38 . This study indicated that discharges of nutrients and pollutants from trans-provincial inbound river watersheds were greater than direct discharges from the three coastal city cluster regions (Table S4 ).…”

Coastal wetland ecosystems have experienced serious losses of area and ecological function and are currently facing worldwide challenges due to coastal development and global climate change. This study attempted to explore patterns and possible factors driving loss of natural coastal wetlands due to land conversion (permanent loss) and ecological degradation (temporal loss) in three urbanizing coastal city clusters, China in the period of 1990–2015. The natural coastal wetland area was substantially lost due to land conversion highly related to regional economic development. The ecological degradation, assessed as a function of surface water quality, resulted in much greater impairment area of natural coastal wetlands. This impairment was predominantly driven by inbound river pollutants’ discharge, rather than local discharge. This study suggests that the ecological degradation should be considered as well as the land conversion loss for conserving the remaining natural coastal wetland ecosystems. The pollutant discharges from the inbound river watersheds need to be mitigated as the local discharges for reducing the functional degradation of the natural coastal wetlands while the regional economic development plan should consider the conservation needs of the remaining natural coastal wetlands worldwide.

“…The ports are subjected to different activities (industrial, commercial, and touristic) that, along with activities occurring in the surrounding areas, have seriously affected the quality of port sediments 11,12,[27][28][29][30][31] . It is worth noting that the sediment contaminant spectrum of a port reveals the impact of the port activity [32][33][34][35][36][37][38] . On these grounds, for the purpose of the present study, different harbors and coastal areas alongside both Adriatic and Ionian Sea were selected.…”

Polycyclic aromatic hydrocarbons (PAHs) are contaminants introduced by different pathways in the marine ecosystem, affecting both aquatic and sediment bodies. Identification of their sources is of vital importance for protecting the marine ecosystem. The attribution of the pollution sources is usually made by using diagnostic molecular ratios of PAHs isomers. The reliability of this approach diminishes when PAHs contents are measured far from their original source, for example in water bodies or in bottom sediments. Conventionally the source attribution is based on time consuming univariate methods. In the present work coupling of molecular ratios with advanced supervised statistical techniques was used to increase the accuracy of the PAH source attribution in bottom sediments. Data on PAHs distribution within 5 port areas, with known pattern port activity, were collected. Evaluation of multiple PAHs ratios at once by means of supervised OPLS-DA technique was performed. A robust descriptive and predictive model was set up and successfully validated. The proposed methodology helps identify PAH transport pathways, highlighting interactions between pollution patterns, port activities and coastal land-use supporting decision makers in defining monitoring and mitigation procedures.

“…Beberapa penelitian menginformasikan kontaminasi logam berat dalam organisme laut tentunya disebabkan oleh tercemarnya lingkungan laut oleh logam berat. Pencemaran logam berat dilingkunga laut seperti yang terjadi di muara sungai (Barletta et al, 2019), teluk (Ahumada et al, 2011Yu et al, 2017) dan perairan pesisir (Vallius, 2015) yang akhirnya akan mengkontaminasi organisme yang ada didalamnya. Keberadaan kedua logam tersebut pada organisme yang didapatkan tentunya setelah mengalami berbagai proses sehingga terdeteksi dalam jaringan organisme .…”

The Semarang and Tegal coastal waters are traditional fishing ground areas. However, the increasing use of coastal areas for various activities will increase pollutants in the coastal waters. Heavy metals are pollutants that always appear in waters and accumulate in marine organisms. These study aims to determine As and Hg metals contained in the tissues of several marine organisms caught on the coast of Semarang and Tegal, Central Java. The analysis of As and Hg concentrations in organismal tissues using ICPMS. The results showed that As and Hg were found in biota such as white shrimp (P. merguensis), blue crab (P. pelagicus), shellfish (A. inaequivalvis) and gastropods (H. ternatanus). Arsenic concentrations in the four biotas caught in Tegal (1.6 – 5.3 ppm) and Semarang (2.58 – 4.9 ppm). Meanwhile, Hg metal (0.02 – 0.15 ppm) in Tegal and (0.034 – 0.15 ppm) in Semarang. The concentration level of As based on the biota caught in the Tegal waters are sequentially Shellfish > White shrimp > Gastropods > Blue swimming crab. Meanwhile, the concentration of Arsenic in the biotas in Semarang waters are sequentially shellfish > white shrimp > blue crab > gastropods. However, Hg metal in the biota obtained in these two areas is very low Pesisir Semarang dan Tegal merupakan daerah penangkapan perikanan tradisional. Namun dengan semakin meningkatnya pemamnfaatan wilayah pesisir untuk berbagai kegiatan akan meningkatkan polutan dalam perairan. Logam berat merupakan polutan yang selalu muncul dalam perairan dan terakumulasi organisme laut. Penelitian ini bertujuan untuk mengetahui logam As dan Hg yang terdapat dalam jaringan beberapa biota yang ditangkap pesisir Semarang dan Tegal Jawa Tengah. Analisa konsentrasi As dan Hg dalam jaringan organisme menguunakan ICPMS. Hasil penelitian menunjukan logam As dan Hg ditemukan dalam biota seperti udang putih (P. Merguensis), rajungan (P. pelagicus), kerang bulu (A. inaequivalvis) dan gastropoda (H. ternatanus). Konsentrasi Arsen di keempat biota yang ditangkap di Tegal (1,6 – 5,3 ppm) dan Semarang (2,58 – 4,9 ppm). Sedangkan logam Hg (0,02 – 0,15 ppm) di Tegal dan (0,034 – 0,15 ppm) Semarang. Tingkat konsentrasi logam As berdasarkan biota yang tertangkap di perairan Tegal secara berurutan Kerang bulu > Udang putih > Gastropoda > Rajungan. Sedangkan konsentrasi Arsen dalam biota di perairan Semarang secara berurutan Kerang bulu > Udang putih > Rajungan > Gastropoda. Namun logam Hg dalam biota yang didapat di kedua daerah tersebut sangat rendah.
