“…The HQ value (49.6) for P-CTXs in Skipjack tuna surpassed the threshold of 1, suggesting that they not only posed a risk to the local population but also posed potential risks for export. The corresponding EDI values for Thailand, Philippines, and Japan were 0.688, 0.751, and 0.702 ng/kg/day, respectively, based on their respective fish consumption rates. − Regularly monitoring the safety of tuna is of utmost importance to protect the well-being of consumers and to maintain the long-term sustainability and viability of Kiribati’s tuna industry.…”

Tropical small island developing states (SIDS), with their geographical isolation and limited resources, heavily rely on the fisheries industry for food and revenue. The presence of marine lipophilic phycotoxins (MLPs) poses risks to their economy and human health. To understand the contamination status and potential risks, the Republic of Kiribati was selected as the representative tropical SIDS and 55 species of 256 coral reef fish encompassing multiple trophic levels and feeding strategies were collected to analyze 17 typical MLPs. Our results showed that the potential risks of ciguatoxins were the highest and approximately 62% of fish species may pose risks for consumers. Biomagnification of ciguatoxins was observed in the food web with a trophic magnification factor of 2.90. Brevetoxin-3, okadaic acid, and dinophysistoxin-1 and -2 were first reported, but the risks posed by okadaic acid and dinophysistoxins were found to be negligible. The correlation analysis revealed that fish body size and trophic position are unreliable metrics to indicate the associated risks and prevent the consumption of contaminated fish. The potential risks of MLPs in Kiribati are of concern, and our findings can serve as valuable inputs for developing food safety policies and fisheries management strategies specific to tropical SIDS contexts.

“…Keywords: Water, Human Activities, Biota, Ecosystems, Environmental Pollutants PENDAHULUAN Pesisir merupakan salah satu wilayah yang rentan terhadap perubahan lingkungan karena mempertemukan dua entitas sehingga perubahan di darat ataupun laut akan mempengaruhi kondisi pesisir. Beberapa aktivitas manusia yang berpotensi mempengaruhi wilayah pesisir berupa kegiatan industri, pertambangan, alih fungsi lahan menjadi perkebunan, pertanian, perikanan, pemukiman berpotensi menurunkan kualitas perairan yang berasal sekitar daerah aliran sungai (Huzairiah et al, 2022;Ritonga, 2014;Ritonga et al, 2022;Samson et al, 2013). Salah satu hasil buangan industri dan aktifitas manusia di darat yang mengandung logam berat adalah timbal (Pb).…”

Aktivitas manusia di kawasan pesisir Balikpapan seperti industri, perkapalan, pelabuhan, dan permukiman berpotensi melepaskan limbah ke ekosistem pesisir. Salah satu limbah beracun bagi biota perairan di ekosistem pesisir adalah Timbal (Pb), yang logamnya dapat mengendap dan terakumulasi dalam sedimen mangrove. Tujuan dari penelitian ini adalah untuk mengetahui kandungan Pb dan tingkat cemaran logam Pb pada sedimen. Sampel sedimen diambil dari 6 stasiun berbeda menggunakan pipa PVC yang dibenamkan di kawasan Graha Indah Mangrove Center, Balikpapan. Sampel sedimen didestruksi asam dan dianalisis menggunakan Atomic Absorption Spectrophotometer (AAS) AA-7000 pada panjang gelombang 217 nm. Ditemukan bahwa konsentrasi Pb dalam sedimen antara 2,23 dan 14,0 ng/g dengan rata-rata 6,24 ± 3,09 ng/g (berat kering). Perbandingan kandungan Pb antar stasiun berbeda signifikan (p<0,05). Namun, tidak ada perbedaan kandungan Pb yang signifikan (p>0,05) jika dibandingkan berdasarkan sumber pencemarnya. Variasi kandungan Pb pada sedimen mungkin dipengaruhi oleh aktivitas manusia sebagai sumber limbah Pb di lokasi penelitian, sirkulasi air dari sungai yang mengandung bahan organik dan anorganik yang mengandung Pb, serta pengaruh arus pasang surut dari Teluk Balikpapan. Secara umum, kandungan Pb dalam sedimen tidak melebihi baku mutu, nilai faktor kontaminasi rendah (CF<1) dan indeks geoakumulasi (I-geo) tidak tercemar (I-geo≤0).
