Analysis of the biochemical and histopathological impact of a mild dose of commercial malathion on Channa punctatus (Bloch) fish

Toxicology Reports, Journal Year: 2021, Volume and Issue: 8, P. 443 - 455

Published: Jan. 1, 2021

The intensive application of pesticides without proper disposal management has led their excess residues to reach the neighbouring aquatic ecosystem and its inhabitants mainly fish. In natural water body get diluted, therefore study silent toxic effect, a low dose malathion (0.4 mg/L; 1/20th 96-h LC50 value) for different duration (1, 4, 8, 12 days) was evaluated through biochemical histopathological biomarkers blood hepatorenal tissues Channa punctatus. With increase in pesticide exposure periods, biometric indices: Condition Factor (K), HSI KSI weight decreased. Among alterations exposed fish, serum glucose levels reduced by 72.23 % while protein amounts increased 29.03 days Other parameters, viz., cholesterol, albumin, phosphorous, remained same as control fish after exposure. Though bilirubin (total direct) followed biphasic response, it 60 compared control. Biochemical changes are reflecting induction compensatory energy mechanism cope up with stress. transaminases ALP biomarker enzymes used liver functionality test declined order AST > ALT time-dependent manner serum, indicating injuries due malathion. elevated urea, BUN, creatinine, Ca2+ revealed renal dysfunction. treated antioxidative (SOD CAT) LPO activities were significantly higher kidney than controls. Further, histological examination registered progressive damages periods Thus, even small could severely deteriorate structure function tissue on prolonged exposure, utmost care should be taken prevent seepage into bodies.

Ecological risk assessment of pesticide residues in soils from vegetable production areas: A case study in S-Nepal

The Science of The Total Environment, Journal Year: 2021, Volume and Issue: 788, P. 147921 - 147921

Published: May 21, 2021

Pesticides pose a serious risk to ecosystems. In this study, we used European Food Safety Authority methods, such as quotient (RQ) and toxicity exposure ratios (TER), assess the potential ecological risks of 15 pesticide residues detected in agricultural soils Gaidahawa Rural Municipality Nepal. The mean maximum concentrations soil were for characterization related organisms. RQmean, TERmean RQmaximum, TERmaximum determine general worst-case scenarios, respectively. Of all pesticides soils, no observed effect concentration (NOEC) 27% was not available literature tested organisms their TER RQ could be calculated. threshold value ≥1 indicates high Similarly, ≥5, which is acceptable trigger point chronic exposure, an risk. results showed that scenario (RQmaximum) indicated from chlorpyrifos [RQmaximum > 9 at depths (cm) 0–5, 15–20 35–40 layer]; imidacloprid (1.78 cm layer) profenofos (3.37 0–5 1.09 layer). Likewise, depths, calculated both scenarios ranged 0.37 3.22, indicating F. candida. Furthermore, organophosphate sampling sites mainly due chlorpyrifos, except two study where profenofos. Ecological assessment (EcoRA) use area EFSA some localities farmers practiced conventional farming.
