Toxicity assessment of effluent from a potato-processing industry in Cyprinus carpio.

Potato (Solanum tuberosum) cultivation faces the challenge of excessive pesticide use. During processing, the disposal of large volumes of contaminated water into water bodies can result in severe environmental damage, such as fish deaths. This study aimed to evaluate the toxicological effects of chemical compounds present in the effluent from a potato-processing industry using the test organism Cyprinus carpio.

Acute Silver Catfish (Rhamdia quelen) Exposure to Chlorantraniliprole Insecticide.

The aim of the current study is to investigate whether silver catfish (Rhamdia quelen) individuals exposed to commercial formulation of the chlorantraniliprole insecticide used in rice crops present changes in biochemical parameters. Fifty-four (54) silver catfish individuals were distributed in six units per tank (n = 6/repetition; triplicate/treatment) and subjected to the following treatments: T1-control, without insecticide; T2 (0.02 µg/L of insecticide) and T3 (0.

Enzyme assays and toxicity of pig abattoir waste in Eisenia andrei.

Due to high global demand, large amounts of abbattoir waste are generated from pork production. Mismanagement of abattoir waste on agricultural lands can result in soil and water contamination with pathogens and contaminants like metals and nutrients. Therefore, possible effects on soil organisms prior to application should be evaluated.

Exposure to tebuconazol in rice field and laboratory conditions induces oxidative stress in carp (Cyprinus carpio).

Pesticides can have an effect on the biochemical and physiological functions of living organisms. The changes seen in fish and their response to pesticides can be used as an example for vertebrate toxicity. In this study, carp fish (Cyprinus carpio) were exposed to different concentrations of tebuconazol fungicide, by rice field (31.

Oxidative stress biomarkers in Cyprinus carpio exposed to commercial herbicide bispyribac-sodium.

Cyprinus carpio were exposed under field conditions to 20.87 microg l(-1) of commercial herbicide bispyribac-sodium (Nominee, SC), during 7, 21 and 72 days. Enzymatic parameters such as catalase (CAT), glutathione S-transferase (GST) and acetylcholinesterase (AChE) activities, as well as thiobarbituric acid-reactive substances (TBARS) and protein carbonyl contents were studied in different tissues.
