Non-steroidal anti-inflammatory drugs (NSAID) are recently monitored in the aquatic environment. Naproxen (NPX), paracetamol (PCT) and their transformation products can influence the biochemical and physiological processes at the sub-cellular and cellular levels taking part in the growth and development of plants. This study aimed to compare the effects of NPX and PCT, drugs with different physico-chemical

Exposure to the persistent organic pollutant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD, dioxin) disrupts development of the zebrafish inner ear Aquat. Toxicol. (IF 5.202) Pub Date : 2023-04-12 Layra G. Cintrón-Rivera, Gabrielle Oulette, Aishwarya Prakki, Nicole M. Burns, Ratna Patel, Rachel Cyr, Jessica Plavicki
Dioxins are a class of highly toxic and persistent environmental pollutants that have been shown through epidemiological and laboratory-based studies to act as developmental teratogens. 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), the most potent dioxin congener, has a high affinity for the aryl hydrocarbon receptor (AHR), a ligand activated transcription factor. TCDD-induced AHR activation during development

Single and combined effects of cadmium, microplastics, and their mixture on whole-body serotonin and feeding behaviour following chronic exposure and subsequent recovery in the freshwater leech, Nephelopsis obscura Aquat. Toxicol. (IF 5.202) Pub Date : 2023-04-08 Lauren Zink, Steve Wiseman, Gregory G. Pyle
Microplastics and metals are contaminants detected in many freshwater systems globally. Interactions of microplastics with other contaminants including cadmium poses potential threats to the health of aquatic organisms including Nephelopsis obscura, a predatory leech species that is widespread and serves important ecological and economic roles. The feeding biology of N. obscura has been well-described

Recommendations for advancing media preparation methods used to assess aquatic hazards of oils and spill response agents Aquat. Toxicol. (IF 5.202) Pub Date : 2023-04-03 Thomas Parkerton, Michel Boufadel, Trond Nordtug, Carys Mitchelmore, Kat Colvin, Dana Wetzel, Mace G Barron, Gail E Bragin, Benjamin de Jourdan, Jennifer Loughery
Laboratory preparation of aqueous test media is a critical step in developing toxicity information needed for oil spill response decision-making. Multiple methods have been used to prepare physically and chemically dispersed oils which influence test outcome, interpretation, and utility for hazard assessment and modeling. This paper aims to review media preparation strategies, highlight advantages

Effects of antimony exposure on DNA damage and genome-wide variation in zebrafish (Danio rerio) liver Aquat. Toxicol. (IF 5.202) Pub Date : 2023-04-06 Qin Yao, Aijiang Yang, Xia Hu, HaiTao Zou, Jiangfeng Chen, Qing Li, Shenghan Lv, Xuegang Yu, Cixing Li
Antimony (Sb) is a potentially toxic and carcinogenic cumulative contaminant that poses a serious threat to aquatic ecosystems. To better clarify the genotoxicity of Sb and its mechanism of action. In this study, we investigated DNA damage and genome-wide variation in the liver of a model organism, zebrafish (Danio rerio), under subacute Sb exposure and explored its potential toxicological mechanisms

The effects of exogenous amino acids on production of microcystin variants in Microcystis aeruginosa Aquat. Toxicol. (IF 5.202) Pub Date : 2023-04-06 Yaxin Guo, Xiating Zhao, Zongcheng Yao, Zongyao Qian, Yuting Wang, Qiming Xian
Dissolved free amino acids are a significant component of dissolved organic nitrogen (DON) in natural waterbodies. The effects of four amino acids (glutamic acid, phenylalanine, leucine, and arginine) on the growth and microcystins (MCs) production of Microcystis aeruginosa were studied in batch culture. The profiles of five MCs variants and the expression levels of target genes involved in MCs biosynthesis
