Research ArticleOpen accessIn the keywordsLimnological Studies on the Wetland Lake, Al-Asfar, with Special References to Heavy Metal Accumulation by FishGehan H. Fahmy, Adel A. FathiProblem statement: Al-Asfar Lake is one from the important shallow wetland lakes. It is located on the eastern region of Saudi Arabia, Al-Hassa Province. However, much of their limnology and its biotic information are still unknown to the scientific community. The study aims to follow variations in physico-chemical characteristics, phytoplankton and to determine the sort of pollutants such as heavy … …American Journal of Environmental Sciences, Vol. 7, Issue 6 · 31 Dec 2011 · 9,942 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrated Monitoring of Endocrine-Disrupting Chemicals: Analytical Chemistry and Biological Assessment ApproachesChangjin Li, Jing Huo, Zijun Dou et al.Endocrine-Disrupting Chemicals (EDCs) in aquatic environments pose significant threats to ecosystems and human health. These compounds interfere with hormonal regulation at low concentrations and have non-monotonic dose-response relationships, posing challenges to conventional risk assessment. This review systematically compares current EDC monitoring methods, including instrumental chemical analysis and receptor-based biological detection systems, to evaluate sensitivity thresholds, sample throughput, and mechanistic selectivity … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 3 Jul 2026 · 1,081 accessesView PDFCite
Research ArticleOpen accessIn the abstractToxicity of Dinoflagellate (Gonyaulax verior) from Makassar Strait Waters on Medaka Fish (Oryzias javanicus) Embryo DevelopmentNita Rukminasari, Khusnul Yaqin, Jamaluddin Fitrah AlamThis study investigates the toxic effects of the dinoflagellate Gonyaulax verior on the embryonic development of medaka fish (Oryzias javanicus) sourced from four distinct aquatic environments in the Makassar Strait. Given the increasing presence of harmful algal blooms in marine ecosystems, understanding the impact of toxic dinoflagellates is crucial for assessing risks to fish populations. Embryos were exposed to varying … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 20 Nov 2025 · 2,123 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Identification and Quantification of Marine Fish from Environmental DNA in Sulawesi Waters (Makassar Strait, Flores Sea and Bone Bay), IndonesiaNita Rukminasari, Andi Aliah Hidayani, Wilma Joanna Carolina Moka et al.The emergence of environmental DNA (eDNA) represents a recent methodological breakthrough for evaluating the presence of aquatic vertebrate species. This approach offers a relatively simple method with significant implications for conservation biology. Our study aim was to augment our understanding of marine fish biodiversity in Sulawesi waters. We employed eDNA metabarcoding to investigate fish biodiversity within Sulawesi waters, specifically focusing … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 5 Jul 2024 · 5,005 accessesView PDFCite
Research ArticleOpen accessIn the abstractDiversity of Culturable Halophilic Archaea and Bacteria from Chott Tinsilt and El Malah Salt-Lake in AlgeriaAkmoussi-Toumi Siham, Khemili-Talbi Souad, Kebbouche-Gana Salima et al.At the limits of life, hyper-saline aquatic ecosystems; Chott and Sebkha are a model of choice of extreme environments, housing a halophilic microflora that had to adapt to these conditions. In Algeria, these ecosystems are poorly studied. However, our study was carried out on the waters of Chott Tinsilt and Sebkha El Malah. The study of this microflora revealed the … …Current Research in Bioinformatics, Vol. 8, Issue 1 · 28 Feb 2020 · 7,536 accessesView PDFCite
Review ArticleOpen accessIn the abstractCorrelation of Biodiversity of Algal Genera with Special Reference to the Waste Water Effluents from IndustriesRitu Singh Rajput, Sonali Pandey, Seema BhadauriaPollution is the introduction of contaminants, which cause adverse change, into the natural environment and mainly from external inputs like sewage, waste from industries, oil spills and agricultural use of pesticides. Anthropogenic activity-reflected in the use of toxic metals and organic pollutants-has increased levels of soil contamination and damage to aquatic systems. Ecosystems maintain water quality and withstand pressure from … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 9 Dec 2016 · 8,608 accessesView PDFCite
Research ArticleOpen accessIn the abstractSome Pollutants (PAHs and OPPs) in Caspian Sea Coast-IranChangiz MohammadizadehPAHs form one of the most important classes of persistent pollutants. Sediment samples were taken from the eastern Caspian Sea coast of Mazandaran state analyzed by (GC-MS) for PAHs. Sediment samples were collected from eastern part of southern Caspian Sea in Mazandaran Province. Stations were Amirabad (10), Sari (5), Babolsar (5) and Noushahr (5) to determinate distribution and to source … …Current Research in Geoscience, Vol. 3, Issue 2 · 10 Jun 2014 · 6,985 accessesView PDFCite
Research ArticleOpen accessIn the abstractToxicity of Industrial Wastewater Acting Singly or in Joint-Ratios on Clarias gariepinusAina Olubukola Adeogun, Azubuike Victor ChukwukaFreshwater ecosystems were the most vulnerable to pollution due to their easy accessibility for disposal of wastewaters leading to deterioration of water quality. Ona river, Ibadan, Nigeria is part of a dense network of inland watercourses emptying into the Lagos lagoon and receives industrial effluents from a food and beverage industry. The single and joint-action toxicity of effluents from these … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 18 Jun 2012 · 7,024 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Shrimp Farm Effluent on Water Quality in Coastal Areas of the World Heritage-Listed Ha Long BayThuyet D. Bui, Jim Luong-Van, Chris M. AustinProblem statement: Shrimp farming has rapidly developed in coastal areas of the World Heritage-listed Ha Long Bay since the last decade. Effluent discharged from shrimp farms with high levels of nutrient waste may cause eutrophication in receiving waterways. Therefore, assessing water quality at tidal creeks receiving shrimp farm effluent in coastal areas of Ha Long Bay supports environmental protection and … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 3 Mar 2012 · 11,283 accessesView PDFCite
