“…In the present study, however, more than 50% of the individuals presented morphological malformations, reflecting the toxic effects of this compound on both study species. This neonicotinoid pesticide also caused morphological malformations in birds exposed to 2.5–20 µg 65 , and fish exposed to 300 µg L −1 and 1000 µg L −1 of imidacloprid 33 , reflecting the more ample potential environmental impacts of this this insecticide.…”

“…There are several studies about of imidacloprid toxicity in many non-target organisms found in aquatic environments, such as aquatic insects 32 , fish 33 , and anuran amphibians 34 , 35 . In the US Environmental Protection Agency’s measured concentrations of pesticides for aquatic life and human health benchmarks 36 , chronic toxicity values for freshwater invertebrates (0.39 μg L −1 ) and fish (9000 μg L −1 ) were available, but not amphibians.…”

“…Insects are expected to be more sensitive to imidacloprid than fish and amphibians, but it is not yet known what concentrations actually cause toxic effects on aquatic vertebrates. In fish, there is data showing that several malformations of common carp embryos and larvae were induced by the toxicity of imidacloprid at concentrations of 300 and 1000 µg L −1 33 . In anuran amphibians, Feng et al 37 observed an increasing in Rana limnocharis and Rana nigronaculata mortality from imidacloprid doses of 30 mg L −1 and 45 mg L −1 , respectively.…”

Imidacloprid is a neonicotinoid insecticide used to control agricultural pests around the world. This pesticide can have adverse effects on non-target organisms, especially in aquatic environments. The present study evaluated the toxicity of an imidacloprid-based insecticide in amphibians, using Leptodactylus luctator and Physalaemus cuvieri tadpoles as study models. Spawning of both species were collected within less than 24 h of oviposition from a non-agricultural land at Erechim, Rio Grande do Sul state, Brazil. Survival, swimming activity, body size, morphological malformations, and genotoxic parameters were analyzed at laboratory conditions. A short-term assay was conducted over 168 h (7 days) with five different concentrations of imidacloprid (3–300 µg L−1) being tested. The insecticide did not affect survival, although the tadpoles of both species presented reduced body size, malformed oral and intestine structures, and micronuclei and other erythrocyte nuclear abnormalities following exposure to this imidacloprid-based compound. Exposure also affected swimming activity in L. luctator, which reflected the greater sensitivity of L. luctator to imidacloprid in comparison with P. cuvieri. The swimming activity, body size, and malformations observed in L. luctator and the morphological malformations found in P. cuvieri indicated that even the lowest tested concentration of the insecticide were harmful to amphibians. At concentrations of over 3 μg L−1, P. cuvieri presents a smaller body size, and both species are affected by genotoxic cell damage. This demonstrates that imidacloprid is potentially toxic for the two study species at environmentally relevant concentrations.

“…In natural populations of amphibians, morphologically malformed individuals generally constitute a small fraction of less than 2% (Ouellet 2000); however, the high number of damage (> 50% of individuals) by imidacloprid observed in this study demonstrates the high toxicity of this compound to the studied species. This neonicotinoid also caused damage to body structures in at least two other groups of vertebrates, birds (Hussein and Singh 2016) and sh (Islam et al 2019), showing the importance of evaluating different groups of animals.…”

Imidacloprid is a neonicotinoid insecticide widely used worldwide, but which can cause adverse effects on non-target organisms, especially in aquatic environments. This study aimed to evaluate the chronic toxicity of an insecticide-based imidacloprid in amphibians, using Leptodactylus latrans and Physalaemus cuvieri tadpoles. The parameters of survival, swimming activity, body size, damage to body structures and genotoxicity for both species were analyzed; and the ecological risk of this insecticide calculated. Chronic short-term assay was carried out for 168 h (7 days) and five concentrations of imidacloprid, between 3 and 300 µg L-1, were tested. The insecticide did not affect the tadpoles survival tadpoles; however, both species tested showed smaller body size, damage to the mouth and intestine and the induction of micronuclei and other erythrocytes nuclear abnormalities after exposure to imidacloprid-based herbicide. Insecticide exposure affected the swimming activity in L. latrans, which contributes to the greater sensitivity of L. latrans to imidacloprid when compared to P. cuvieri. All parameters analyzed indicated that the insecticide presents an ecological risk for both species at concentrations greater than 3 µg L-1. This demonstrates the genotoxicity of the insecticide imadacloprid, which can contribute to the population decline of L. latrans and P. cuvieri species in natural systems.

“…At 10% of the L C 50 (7800 ppb) for the fertilised eggs, depreciation of the viability of embryos in eggs was noticeable, decreasing from 92% (control) to 90% [86]. Islam et al [88] also reported damage at early stages of development: the 48-h L c 50 was 611 ppb for embryos and 2.1 × 10 4 ppb for larvae.

The Owena River Basin in Nigeria is an area of agricultural importance for the production of cocoa. To optimise crop yield, the cocoa trees require spraying with neonicotinoid insecticides (Imidacloprid, Thiacloprid Acetamiprid and Thiamethoxam). It is proposed that rainwater runoff from the treated area may pollute the Owena River and that these pesticides may thereby enter the human food chain via six species of fish (Clariasgariepinus, Clariasanguillaris, Sarotherodongalilaeus, Parachannaobscura, Oreochromisniloticus and Gymnarchusniloticus) which are cultured in the river mostly for local consumption. This work aims to establish a working method to quantify the likely levels of the insecticides in the six species of fish, firstly by undertaking a laboratory-based study employing the QuEChERS method to extract the four neonicotinoids from fish purchased in marketplace in the UK, spiked with known quantities of the pesticide and using liquid chromatography coupled with tandem mass spectrometry (LC-MS-MS) as the detection method; secondly, by using these samples to optimise the detection method for very low levels of pesticides, then applying the optimised techniques to the analysis of three of each six species of fish taken from the Owena River. A significant benefit of this combined technique is that only small samples of fish are required. Success with this part of the study showed that very low concentrations of the insecticides could be detected in fish muscle. The third aim is to apply a simple quantitative risk assessment model using the data sets obtained, together with information about daily diet, human body weight and recommended safety limits of pesticides in food to illustrate how human health may be affected by the consumption of these fish. The multiple determinations of neonicotinoids in edible fishes in Nigeria are pioneer research and fill a gap in addressing the relationship between waterborne pesticides and food quality in the country. Fundamentally, this work is an exercise to demonstrate the applicability of the aforementioned instrumental method of analysis to fish muscle, which requires only a small sample size of fish; a large number of fish is not required for a proof of concept, in this case. Although not a monitoring programme for the whole Owena River Basin ecosystem per se, this work successfully demonstrates the technical feasibility of a system of chemical analysis and establishes the foundation for ecological surveys in the immediate future. Parameters involving exposures to xenobiotics in ecotoxicological modelling can now be expressed in terms of both mass and molar concentrations of a chemical in animal tissues if so desired.
