The Effects of Salicylic Acid on Juvenile Zebrafish Danio rerio Under Flow-Through Conditions.

The aquatic environment is becoming increasingly contaminated with pharmaceuticals. Salicylic acid (SA), which can be used individually or appear as a degradation product of the widely used acetylsalicylic acid was chosen for testing. Juvenile zebrafish Danio rerio were subjected to OECD test No.

The effect of the fluoroquinolone norfloxacin on somatic indices and oxidative stress parameters in early stages of common carp (Cyprinus carpio L.).

Objectives: The aim of this study was to assess the effect of the subchronic exposure of early stages of common carp (Cyprinus carpio L.) to norfloxacin using morphometric data and oxidative stress parameters.

Methods: A subchronic toxicity test was performed on fertilized embryos of common carp according to the OECD Guidelines No.

The effects of ciprofloxacin on early life stages of common carp (Cyprinus carpio).

The authors performed a toxicity test with ciprofloxacin in fertilized eggs of common carp according to guideline 210 of the Organisation for Economic Co-operation and Development. The tested concentrations were 1 μg L(-1) , 100 μg L(-1) , 500 μg L(-1) , 1000 μg L(-1) , and 3000 μg L(-1) . Accelerated hatching was found in all groups exposed to ciprofloxacin, but significant growth reduction was found only in the group exposed to the highest concentration (3000 μg L(-1) ).

Effect of salicylic acid on early life stages of common carp (Cyprinus carpio).

Environmental concentrations of pharmaceutical residues are often low; nevertheless, they are designed to have biological effects at low doses. The aim of this study was to assess the effects of salicylic acid on the growth and development of common carp (Cyprinus carpio) early life stages with respect to antioxidant defence enzymes. An embryo-larval toxicity test lasting 34 days was performed according to OECD guidelines 210 (Fish, Early-life Stage Toxicity Test).

The effects of subchronic exposure to ciprofloxacin on zebrafish (Danio rerio).

Objectives: The aim of this study was to assess the impact of ciprofloxacin in Danio rerio on growth, on the development of histopathological changes in selected organs (gills, kidney, liver), and on the activity of some oxidative stress markers during a 28-day toxicity test.

Methods: Juvenile growth tests were performed on D. rerio according to OECD guideline No.

Norfloxacin--toxicity for Zebrafish (Danio rerio) focused on oxidative stress parameters.

The aim of the study was to investigate the effects of subchronic exposure of zebrafish (Danio rerio) to a fluoroquinolone norfloxacin, using selected oxidative stress parameters as a target. Toxicity tests were performed on zebrafish according to the OECD Guidelines number 203 and number 215. In the Subchronic Toxicity Test, a significant (P < 0.

Effects of mixture of pharmaceuticals on early life stages of tench (Tinca tinca).

Ubiquitous occurrence of pharmaceuticals in aquatic environment results in concern about potential adverse the effects on nontarget organisms. In water, drugs are present in complex mixtures, in which complicated interactions affect toxicity of single components. The purpose of this study was to examine effect of 35-day-long exposure to mixture of ibuprofen, diclofenac, and carbamazepine on the mortality, growth, early ontogeny, and histopathological changes in tench (Tinca tinca).

Evaluation of ibuprofen toxicity for zebrafish (Danio rerio) targeting on selected biomarkers of oxidative stress.

Objectives: The aim of the study was to investigate the effects of subchronic exposure of zebrafish to ibuprofen, using selected oxidative stress parameters as a target.

Design: Toxicity tests were performed on Danio rerio according to OECD No. 203 and No.

The effects of atrazine exposure on early life stages of common carp (Cyprinus carpio).

Objectives: Atrazine and its chloro-s-triazine metabolites are found in surface water and groundwater of the Czech Republic, although their use has been banned since 2005. The objective of the study was to determine the toxic effects of atrazine at an environmentally relevant concentration of atrazine, 0.3 μg.

Acute toxicity of acetylsalicylic acid to juvenile and embryonic stages of Danio rerio.

Objectives: The aim of this study was to compare the acute toxicity of acetylsalicylic acid to embryonic and juvenile stages of aquarium fish - zebrafish (Danio rerio), oxidative stress parameters and detoxifying enzyme.

Methods: Tests were performed according to OECD No. 203 (Fish, acute toxicity test) and OECD No.
