Toxicity of Nanoparticulate Nickel to Aquatic Organisms: Review and Recommendations for Improvement of Toxicity Tests

Toxicity of fluoroquinolone antibiotics to aquatic organisms.

Toxicity tests were performed with seven fluoroquinolone antibiotics, ciprofloxacin, lomefloxacin, ofloxacin, levofloxacin, clinafloxacin, enrofloxacin, and flumequine, on five aquatic organisms. Overall toxicity values ranged from 7.9 to 23,000 microg/L. The cyanobacterium Microcystis aeruginosa was the most sensitive organism (5-d growth and reproduction, effective concentrations [EC50s] rang...

Guanicid and Phmg Toxicity Tests on Aquatic Organisms

POŠTULKOVÁ EVA, KOPP RADOVAN. 2016. Guanicid and PHMG Toxicity Tests on Aquatic Organisms. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 64(1): 129–134. The emergence and development of new algicidal products is caused by the ever increasing popularity of garden ponds as well as the use of these products in the fi sheries sector, especially for disposal of cyanobacteri...

Agricultural pesticide toxicity to aquatic organisms - a literature review

Toxicity of anthelmintic drugs (fenbendazole and flubendazole) to aquatic organisms

Flubendazole (FLU) and fenbendazole (FEN) belong to benzimidazoles-pharmaceuticals widely used in veterinary and human medicine for the treatment of intestinal parasites as well as for the treatment of systemic worm infections. In recent years, usage of these drugs increased, which resulted in a larger contamination of the environment and possible negative effects on biota. Hence, in our resear...

Pesticide Toxicity Index--a tool for assessing potential toxicity of pesticide mixtures to freshwater aquatic organisms.

Pesticide mixtures are common in streams with agricultural or urban influence in the watershed. The Pesticide Toxicity Index (PTI) is a screening tool to assess potential aquatic toxicity of complex pesticide mixtures by combining measures of pesticide exposure and acute toxicity in an additive toxic-unit model. The PTI is determined separately for fish, cladocerans, and benthic invertebrates. ...
