“…Our results about dose dependent decrease in total protein observed might be due to counter mechanism against different toxicity sign occurred due to exposure of Imidacloprid and are in agreement with reports available in other model organisms studied like in Channa punctatus [40] and Quails [41]. Rajput et al [42] reported that Imidacloprid caused up to 49% protein loss at lethal concentration (4 ppm) in liver in walking fish and at sub-lethal dose (2 ppm) caused 27% protein loss. In contrary no changes in total protein reported in chicken [35] and rat [32] after Imidacloprid exposure.…”

Imidacloprid insecticide was selected to study its effects on biochemical (total protein, acetylcholinestrase and nucleic acids) and histological (liver) parameters in female albino mice at orally administered doses of 25, 50 and 75% LD 50 Imidacloprid and 40 mg/kg bw Cyclophosphamide (CP) and distilled water (DW). Significant decrease in total protein (P<0.01), acetylcholinestrase (P<0.001) and DNA (P<0.05) were observed with increase in doses as compared to control group whereas slight dose dependent significant increase was noticed for RNA (P<0.01). The change noticed in DNA and RNA for low dose of Imidacloprid was insignificant. The maximum damage with CP and 75% LD 50 Imidacloprid dose were noticed. Liver of mice showed degeneration of hepatocytes, dilation of sinusoids, irregular hepatic cords arrangement, leucocytes infiltration, necrosis and hemorrhages. This reveals biochemical and histotoxicity induction by Imidacloprid so awareness about its judicious use by farmers/users is of pivotal importance to have safe next generations.

“…While acute mortality of fish from the neonicotinoid insecticides is rare, Rajput et al. ( 2012 ) reported that imidacloprid was toxic to freshwater catfish, Clarias batrachus , when exposed for 21 days, but only at high doses. Protein loss was reported when exposed to high concentrations that later caused lethality.…”

Large-scale use of the persistent and potent neonicotinoid and fipronil insecticides has raised concerns about risks to ecosystem functions provided by a wide range of species and environments affected by these insecticides. The concept of ecosystem services is widely used in decision making in the context of valuing the service potentials, benefits, and use values that well-functioning ecosystems provide to humans and the biosphere and, as an endpoint (value to be protected), in ecological risk assessment of chemicals. Neonicotinoid insecticides are frequently detected in soil and water and are also found in air, as dust particles during sowing of crops and aerosols during spraying. These environmental media provide essential resources to support biodiversity, but are known to be threatened by long-term or repeated contamination by neonicotinoids and fipronil. We review the state of knowledge regarding the potential impacts of these insecticides on ecosystem functioning and services provided by terrestrial and aquatic ecosystems including soil and freshwater functions, fisheries, biological pest control, and pollination services. Empirical studies examining the specific impacts of neonicotinoids and fipronil to ecosystem services have focused largely on the negative impacts to beneficial insect species (honeybees) and the impact on pollination service of food crops. However, here we document broader evidence of the effects on ecosystem functions regulating soil and water quality, pest control, pollination, ecosystem resilience, and community diversity. In particular, microbes, invertebrates, and fish play critical roles as decomposers, pollinators, consumers, and predators, which collectively maintain healthy communities and ecosystem integrity. Several examples in this review demonstrate evidence of the negative impacts of systemic insecticides on decomposition, nutrient cycling, soil respiration, and invertebrate populations valued by humans. Invertebrates, particularly earthworms that are important for soil processes, wild and domestic insect pollinators which are important for plant and crop production, and several freshwater taxa which are involved in aquatic nutrient cycling, were all found to be highly susceptible to lethal and sublethal effects of neonicotinoids and/or fipronil at environmentally relevant concentrations. By contrast, most microbes and fish do not appear to be as sensitive under normal exposure scenarios, though the effects on fish may be important in certain realms such as combined fish-rice farming systems and through food chain effects. We highlight the economic and cultural concerns around agriculture and aquaculture production and the role these insecticides may have in threatening food security. Overall, we recommend improved sustainable agricultural practices that restrict systemic insecticide use to maintain and support several ecosystem services that humans fundamentally depend on.

“…A study [17] also reported that the residues of butachlor in paddy field, even though lower than the safe concentration, caused toxic effect to Cyprinus carpio. In another study, butachlor was found to cause remarkable protein loss in Clarias batrachus at both lethal and sub-lethal concentration which might be due to increased proteolysis [18] or by metabolic utilization of ketoacids to glucogenesis pathway for synthesis of glucose [19]. The above results demonstrated adverse effects of butachlor on the normal reproductive process of zebra fish and also found to disrupt the thyroid and sex steroid endocrine systems when exposed to butachlor for 30 days [20].…”

The aim of this study is to determine the levels of atrazine, propanil, alachlor, metolachlor, paraquat, propachlor, butachlor and glysophate in the flesh, liver, intestine and gills of Tilapia zilli, Clarias anguillaris, Synodentis budgetti and Heterotis niloticus from Alau Dam The highest total concentrations of all the studied herbicide residues were detected in Tilapia zillii, follow by Clarias anguillaris, while Synodentis budgetti shows the lowest values. The highest concentrations of all the herbicide residues were detected in the liver of Tilapia zilli and Clarias angullaris while Synodentis budgetti shows the lowest value. Also, the flesh and gills of Tilapia zilli was observed to show the highest levels of all the studied herbicides, while Clarias angullaris shows the lowest value. The values observed for herbicide residues were lower than the WHO and FAO set maximum residue limit (MRL) 0.01 mg/kg and the Acceptable Daily Intake value (ADI) of 0.006 mg/kg which is considered safe for consumption as at the time of the present research work. But their presence in the fish samples also cause for concern, therefore, it is important for relevant agencies to be involve in the management of Alau Dam with respect to herbicide residues.
