“…These varied traits of copepods make them excellent model organisms for ecotoxicological studies (Kulkarni et al ., 2013). The calanoid copepod Acartia tonsa and the harpacticoid species Amphiascus tenuiremis and Nitocra spinipes have been recommended by the International Organisation for Standardisation (ISO, 2007) and OECD (2007 b ) for the evaluation of chronic and acute lethal toxicity of marine contaminants such as herbicides (Noack et al ., 2016), sediment organic contaminants (Macken et al ., 2008), discharge waters (Sonmez, Sivri & Dokmeci, 2016) and oestrogens (Andersen, Halling‐Sørensen & Kusk, 1999). Other studies have stressed the importance of using local species to ensure the ecological relevance of such tests (Butler et al ., 2020).…”

Aquatic invertebrates play a pivotal role in (eco)toxicological assessments because they offer ethical, cost‐effective and repeatable testing options. Additionally, their significance in the food chain and their ability to represent diverse aquatic ecosystems make them valuable subjects for (eco)toxicological studies. To ensure consistency and comparability across studies, international (eco)toxicology guidelines have been used to establish standardised methods and protocols for data collection, analysis and interpretation. However, the current standardised protocols primarily focus on a limited number of aquatic invertebrate species, mainly from Arthropoda, Mollusca and Annelida. These protocols are suitable for basic toxicity screening, effectively assessing the immediate and severe effects of toxic substances on organisms. For more comprehensive and ecologically relevant assessments, particularly those addressing long‐term effects and ecosystem‐wide impacts, we recommended the use of a broader diversity of species, since the present choice of taxa exacerbates the limited scope of basic ecotoxicological studies.This review provides a comprehensive overview of (eco)toxicological studies, focusing on major aquatic invertebrate taxa and how they are used to assess the impact of chemicals in diverse aquatic environments. The present work supports the use of a broad‐taxa approach in basic environmental assessments, as it better represents the natural populations inhabiting various ecosystems. Advances in omics and other biochemical and computational techniques make the broad‐taxa approach more feasible, enabling mechanistic studies on non‐model organisms. By combining these approaches with in vitro techniques together with the broad‐taxa approach, researchers can gain insights into less‐explored impacts of pollution, such as changes in population diversity, the development of tolerance and transgenerational inheritance of pollution responses, the impact on organism phenotypic plasticity, biological invasion outcomes, social behaviour changes, metabolome changes, regeneration phenomena, disease susceptibility and tissue pathologies. This review also emphasises the need for harmonised data‐reporting standards and minimum annotation checklists to ensure that research results are findable, accessible, interoperable and reusable (FAIR), maximising the use and reusability of data. The ultimate goal is to encourage integrated and holistic problem‐focused collaboration between diverse scientific disciplines, international standardisation organisations and decision‐making bodies, with a focus on transdisciplinary knowledge co‐production for the One‐Health approach.

“…Atıksuların karakterizasyonunda bulunan tüm kirleticilerin analizi gerçekleştirilemeyeceği gibi, fizikokimyasal analizler ksenobiyotik bileşiklerin arasındaki sinerjistik veya antagonistik etkileşimleri ifade edemez (5) . Oysa ki, tek başlarına suda bulunma durumlarında dahi giderimleri kompleks olan mikrokirleticilerin, birden fazla kirleticinin etkileşim halindeki giderimi daha da kompleks hale gelebilmektedir (2) .…”

“…Çoğu zaman bu deneylerde, test organizması olarak yüksek yapılı organizmaların kullanılması; etik olarak da uygun görülmemektedir (13) . Ayrıca, balık, su piresi, mikroalg gibi farklı trofik seviyelerdeki canlılarla yapılan toksisite testlerinde, organizma standardizasyonu, özel ekipman gereksinimi, uzun test süreleri ve yeniden üretebilirliğin eksikliği bu biyodeneylerin başlıca dezavantajlarını oluşturmaktadır (5,14) . Besin ağının farklı seviyelerindeki herhangi bir besin/ yiyecek/av dengesinin değişmesi, daha yüksek trofik seviyelerde yer alan türler üzerinde dolaylı bir "alt-üst" etkiye neden olabilmektedir (15) .…”

Son 50 yıldır denizel ekosistemlere sahip ülkeler, evsel ve endüstriyel deşarj kaynaklı kirlilik, aşırı avlanma, yerli olmayan türlerin tehdidi ve iklim değişikliği, sucul ekosistemlerde pH değişimleri gibi antropojenik baskılarla ve çevresel problemler ile karşı karşıyadır. Farklı kaynaklardan gelen ksenobiyotik bileşikler, toksik olan/olmayan maddeler ile kimyasal etkileşim (sinerjistik/antagonistik ters/toplam) içerisinde olup, toksisiteyi meydana getirmektedir. Yüzeysel sularda tespit edilen makro kirleticilerin yanı sıra, mikro kirleticilerin varlığı ve oluşturdukları toksisite son yıllarda giderek artan bir önem kazanmıştır. Evsel ve endüstriyel atıksular aracılığıyla arıtma tesislerine gelen bu kirleticiler ortalama %80 oranlarında giderilebilmektedir. Ancak, özellikle nüfus yoğunluğunun yüksek olduğu büyükşehirlerin atıksu debisi dikkate alındığında, artan yükün giderim verimleri üzerine baskısı sonucunda bu kirleticilerin yüzeysel sulara deşarj yoluyla ulaştığı bilinmektedir. Dolayısıyla, bu çalışmanın amacı İstanbul yüzeysel sularında özellikle dere yolu ile deşarj yapan ileri biyolojik atıksu arıtma tesisleri çıkış sularının yüzey sularına karıştığı alanlardan alınan su numunelerinde akut toksisite seviyelerinin belirlenmesidir. Yöntem: Biyolüminesans bakteri (Aliivibrio fischeri) ile akut toksisite testi gerçekleştirilmiş ve sonuçların yorumlanması için analitik yöntemler kullanılmıştır. Bulgular: Bu istasyonlardan elde edilen sonuçlarda genel olarak "hormesis" verisine rastlanılmıştır. Ambarlı istasyonu yüzey sularının toksisite seviyesinde "aşırı derecede toksik" ve Ataköy istasyonu yüzey sularında "çok toksik" seviyelerine ait sayısal sonuçlar dikkat çekicidir. Sonuç: Kanalizasyon sistemine kaçak deşarj yapan endüstriyel kuruluşların atıksularının içerdiği bazı kirleticiler ve atıksu arıtma tesislerine gelen öncelikli mikrokirleticiler yüzey suları ile buluştuğu noktada, su kalitesini ekotoksikolojik açıdan olumsuz etkileyebilmektedir.

“…However, the acute toxicity test should be as rapid as possible and result within seconds. In recent years we have seen that acute toxicity tests with bioluminescent bacteria, a rapidscreening acute toxicity test, can give results within minutes compared to the other acute toxicities [10][11][12][13].…”

Dyes from different sources often behave with mostly toxic properties when they enter the aquatic ecosystem. The main sources of these toxic substances causing problems in the aquatic ecosystem are wastewaters of the textile and dye industries. The aim of this study was to examine the change of acute toxicity values of wastewaters containing dyestuff depending on time and color parameters. In this study, an acute toxicity test was conducted for 30 seconds, which is shorter than the time specified in the original Microtox test protocol. Thus, the results of the original Microtox Basic Test (BT), Microtox Color Correction Procedure recommended by the manufacturer (BT-CC), and the Microtox Basic Test-30 seconds (sBT) were compared, taking into account the effect of time and color parameters. There is a statistically significant difference between two groups: sBT and BT, and sBT and BT-CC (F = 4.919; p<0.01). The results of sBT have been obtained more rapid and more sensitively than other acute toxicity tests. The sBT, which is time-saving and gives correct result might provide some guidance as a pre-screening test and might be used in routine monitoring.
