Pharmaceutical contamination is an increasing problem globally. In this regard, the selective serotonin reuptake inhibitors (SSRIs)-a group of antidepressants-are particularly concerning. By disrupting serotonergic system, SSRIs have potential to affect ecologically important behaviors in exposed wildlife. Despite this, nature and magnitude behavioral perturbations resulting from environmentally relevant SSRI exposure among species poorly understood. Accordingly, we investigated effects two...
Though pharmaceuticals and other contaminants of emerging concern are increasingly observed in inland water bodies, the occurrence bioaccumulation estuaries coastal ecosystems poorly understood. In present study, select was examined fish from Buffalo Bayou, a tidally influenced urban ecosystem that receives effluent major (∼200 million gallons per day) municipal wastewater treatment plant Houston, Texas, USA. Using isotope dilution liquid chromatography-tandem mass spectrometry, various...
Aquaculture, which is growing 3-5 times faster than terrestrial agriculture, will play an important role to meet future global food production needs. However, over 80% of sewage returned the environment untreated or poorly treated. In developing nations, these nontraditional waters diverse quality are being recycled for aquaculture, yet chemical residues differentially studied. Here, we examined pharmaceuticals, pesticides, polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers...
Abstract Diclofenac is a nonsteroidal anti‐inflammatory drug (NSAID) of growing concern in aquatic environments worldwide; nevertheless, knowledge its effects on biota restricted to few model species with limited information regarding mechanisms impact. In the present study, diclofenac accumulation, metabolic rate, ionoregulation, and oxidative stress were examined at environmentally relevant (0.17 µg L −1 ) elevated (763 concentrations culturally economically important galaxiid fish, inanga...
The determination of nicotine and its major metabolites (cotinine anabasine) in fish tissue was performed using liquid chromatography tandem mass spectrometry. Marine freshwater were purchased from local grocery stores prepared based on a quick, easy, cheap, effective, rugged, safe sample preparation protocol. To determine the highly polar compounds, hydrophilic interaction also used. There modest suppressions measured signals (10%) due to matrix effects marine but no obvious signals. Method...
Per- and polyfluoroalkyl substances (PFAS) are man-made organofluorine chemicals that can contaminate environmental waters have gained worldwide attention over the past two decades. PFAS most frequently detected by mass spectrometric targeted analysis methods which may not detect all in samples. This report describes investigation of adsorbable (AOF) with detection combustion ion chromatography (CIC) for surface wastewaters adsorb to granular activated carbon (GAC) recognition this technique...
Abstract Although freshwater mussels are imperiled and identified as key conservation priorities, limited bioaccumulation information is available on these organisms for contaminants of emerging concern. In the present study we investigated per‐ polyfluoroalkyl substances (PFAS) in model pond mussel Sagittunio subrostratus because provide important ecosystem services components aquatic systems where PFAS occur. selected four representative perfluorinated carboxylic acids sulfonic acids, then...
Bioaccumulation of ionizable pharmaceuticals has been increasingly studied, with most reported aquatic tissue concentrations in field or laboratory experiments being from fish. However, higher levels antidepressants have observed bivalves compared fish effluent-dominated and dependent surface waters. Such observations may be important for biodiversity because approximately 70% freshwater North America are considered to vulnerable extinction. Because experimental bioaccumulation information...
Diltiazem is ubiquitously prescribed and has been reported in many effluents freshwater bodies. Being a calcium channel blocker, diltiazem could disrupt the function of sensory central nervous systems. In present study, using electro-olfactography (EOG), we investigated interaction with olfactory neurons (OSNs) rainbow trout by looking into detection threshold effects immediate (~5 min) acute (24 h) exposure to at 6.6, 66, 660 µg/L. We also studied accumulation drug fish plasma whole body....
