“…Blood is one of the important pathophysiological reflectors of the whole body organism. Therefore, blood parameters such as haematological and biochemical indices can be used as important markers of diagnosing the structural and functional status of fish exposed to pesticides, which induce stress reaction [27, 28]. In our study, acute exposure to atrazine resulted in significant concentration-dependent changes in almost all haematological and biochemical indices and in the case of some indices these alterations were irreversible after 7-day depuration in atrazine-free water.…”

The aim of study was to evaluate the effect of atrazine exposure (5, 15, 20, and 30 mg·L−1) on common carp and the ability of regeneration. During 96 h exposure we observed abnormal behavior in fish exposed to 20 and 30 mg·L−1. Mortality and histological alterations were noticed only in the group exposed to 30 mg·L−1. Most experimental groups showed significantly (P < 0.05) lower values of haemoglobin, haematocrit, leukocyte, and lymphocyte and significantly higher values of monocytes, segmented and band neutrophile granulocytes, and also metamyelocytes and myelocytes. A significantly lower (P < 0.05) leukocyte count was also recorded in experimental groups (5 and 15 mg·L−1) after recovery period. Statistically significant (P < 0.05) alterations in glucose, total protein, lactate, phosphorus, calcium, and biopterin as well as in activities of ALT, AST, ALP, and LDH were found in most experimental groups. These changes were most apparent in the groups exposed to 20 and 30 mg·L−1. Most of the indices were found to be restored after the 7-day recovery period with the exception of LDH, ALT, and lactate in the group exposed to 15 mg·L−1. Our results showed that atrazine exposure had a profound negative influence on selected indices and also on histological changes of common carp.

“…As with our study, increased MCV values were observed. During the recovery period following exposure of fish to tested pesticides, the parameters studied gradually returned to values determined at the beginning of the experiment (Adhikari et al 2004). Anemia in fish exposed to the preparation LASSO MTX may be explained by both the higher degree of erythrocyte destruction and the reduced availability of substances important in erythropoiesis, such as iron and vitamins.…”

“…Units of measured indices: T L -1 , 10 12 cells per litre; g L -1 , grams per litre; L L -1 , litres per litre; fL, femtolitres; pg, picograms carp to diazinon, in the preparation BASUDIN 600 EW, for 96 h. Other authors have observed anemia in common carp exposed to the preparation DECIS FLOW 2.5, which contains deltamethrin as an active substance (Svobodova et al 2003). Adhikari et al (2004) investigated the effects of cypermethrin and carbofuran on certain hematological parameters in a freshwater teleost, Labeo rohita H. and estimated the rate of recovery of these parameters to preexposure levels during the recovery period. In fish exposed for 28 days to sublethal levels of either substance, a significant time and dose-dependent decrease in RBC, Hb, PCV, and oxygen-carrying capacity was observed.…”

The aim of the study was to evaluate subchronic toxic effects of the preparation LASSO MTX (alachlor 42% W/V) on hematological indices and histology of the common carp (Cyprinus carpio L.). In carp exposed for 28 days to LASSO MTX in the concentration of 2,400 microg L(-1), significant differences (p < 0.05), were detected in all indices of the erythrocyte profiles tested except hematocrit (PCV) when compared to controls. At a lower exposure (240 microg L(-1)) concentration of blood hemoglobin and mean corpuscular hemoglobin were significantly reduced. In contrast, no influence of the preparation on leucopoiesis was demonstrated, and only slight changes were observed in histopathological indices.

Toxicity of Buprofezin on the Survival of Embryo and Larvae of African Catfish, Clarias gariepinus (Bloch)

et al. 2013

Buprofezin is an insect growth regulator and widely used insecticide in Malaysia. The present study evaluated the toxic effects of buprofezin on the embryo and larvae of African catfish (Clarias gariepinus) as a model organism. The embryos and larvae were exposed to 7 different concentrations (0, 0.05, 0.5, 5, 25, 50 and 100 mg/L) of buprofezin. Each concentration was assessed in five replicates. Eggs were artificially fertilized and 200 eggs and larvae were subjected to a static bath treatment for all the concentrations. The mortality of embryos was significantly increased with increasing buprofezin concentrations from 5 to 100 mg/L (p< 0.05). However, the mortality was not significantly different (p<0.05) among the following concentrations: 0 (control), 0.05, 0.5 and 5 mg/L. Data obtained from the buprofezin acute toxicity tests were evaluated using probit analysis. The 24 h LC50 value (with 95% confidence limits) of buprofezin for embryos was estimated to be 6.725 (3.167-15.017) mg/L. The hatching of fish embryos was recorded as 68.8, 68.9, 66.9, 66.4, 26.9, 25.1 and 0.12% in response to 7 different concentrations of buprofezin, respectively. The mortality rate of larvae significantly (p<0.05) increased with increasing buprofezin concentrations exposed to 24-48 h. The 24 and 48 h LC50 values (with 95% confidence limits) of buprofezin for the larvae was estimated to be 5.702 (3.198-8.898) and 4.642 (3.264-6.287) mg/L respectively. There were no significant differences (p>0.05) in the LC50 values obtained at 24 and 48 h exposure times. Malformations were observed when the embryos and larvae exposed to more than 5 mg/L. The results emerged from the study suggest that even the low concentration (5 mg/L) of buprofezin in the aquatic environment may have adverse effect on the early embryonic and larval development of African catfish.
