“…Additionally, it is highly soluble in water (351 mg/dL), has high mobility in various types of soil, and has a low adsorption coefficient (Koc=30), enhancing its contamination potential in aquatic environments. It also remains stable in acidic or neutral pH soils, further contributing to its persistence in the environment (Mishra et al 2020; Tang et al 2021; Brovini et al 2023). CF can be absorbed through oral, respiratory, and dermal routes in non-target organisms, causing a cholinergic syndrome, leading to symptoms such as nausea, vomiting, weakness, pain, and, in severe cases, coma and death (Mishra et al 2020).…”

“…Additionally, the impacts of CF exposure on sea bass (Dicentrarchus labrax) included decreased swimming speed and inhibition of acetylcholinesterase (AChE) (Hernández-Moreno et al 2011). Studies on CF exposure in humans have shown an association with the development of neurodegenerative diseases (Kamel et al 2007; Tang et al 2021), alterations in sperm quality, and testosterone levels (Abell et al 2000). The literature has explored the relationship between exposure to carbamates and mental disorders such as depression and anxiety (Freire and Koifman 2013).…”

Carbofuran (CF) is a carbamate class pesticide, widely used in agriculture for pest control in crops. On the other hand, CF is also detected as a contaminant in food and water sources. This pesticide has high toxicity in non-target organisms, and its presence in the environment poses a threat to the ecosystem. Research has revealed that this pesticide acts as an inhibitor of acetylcholinesterase (AChE), inducing an accumulation of acetylcholine in the brain. Consequently, this leads to the emergence of a cholinergic syndrome and various detrimental effects on human health. Nonetheless, our understanding of CF impact on the central nervous system remains elusive. Therefore, this study aimed to investigate the effects of CF on behavioral and neurochemical parameters in adult zebrafish. The animals were exposed for 96 hours to different concentrations of CF (5, 50, and 500 μg/L) and subjected to behavioral assessments in the novel tank test (NTT) and social preference test (SPT). Subsequently, they were euthanized, and their brains were used to evaluate neurochemical markers associated with oxidative stress and AChE levels. In the NTT and SPT, CF did not alter the evaluated behavioral parameters. Furthermore, CF did not affect the levels of AChE, non-protein sulfhydryl groups, and thiobarbituric acid reactive species in the zebrafish brain. However, further research is needed regarding the environmental exposure of this compound to non-target organisms.

“…It is mostly applied as a seed treatment in maize fields 7 and can be absorbed by plants 8–11 . Carbosulfan [half‐maximal lethal dose (LD 50 ) = 250 mg/kg in rats] is metabolized to carbofuran (LD 50 = 7.8 mg/kg in rats) by hydrolysis, which is then usually hydroxylated and oxidized to form 3‐hydroxycarbofuran (LD 50 = 21.9 mg/kg in rats) and 3‐ketocarbofuran (LD 50 = 108 mg/kg in rats), respectively 12–14 . These metabolites are more toxic than their parent compound 15 .…”

BACKGROUNDThe insecticide carbosulfan is usually applied as a soil treatment or seed‐coating agent, and so may be absorbed by crops and pose dietary risks. Understanding the uptake, metabolism and translocation of carbosulfan in crops is conducive to its safe application. In this study, we investigated the distribution of carbosulfan and its toxic metabolites in maize plants at both the tissue and subcellular levels, and explored the uptake and translocation mechanism of carbosulfan.RESULTSCarbosulfan was mainly taken up by maize roots via the apoplast pathway, was preferentially distributed in cell walls (51.2%–57.0%) and most (85.0%) accumulated in roots with only weak upward translocation. Carbofuran, the main metabolite of carbosulfan in maize plants, was primarily stored in roots. However, carbofuran could be upwardly translocated to shoots and leaves because of its greater distribution in root‐soluble components (24.4%–28.5%) compared with carbosulfan (9.7%–14.5%). This resulted from its greater solubility compared with its parent compound. The metabolite 3‐hydroxycarbofuran was found in shoots and leaves.CONCLUSIONCarbosulfan could be passively absorbed by maize roots, mainly via the apoplastic pathway, and transformed into carbofuran and 3‐hydroxycarbofuran. Although carbosulfan mostly accumulated in roots, its toxic metabolites carbofuran and 3‐hydroxycarbofuran could be detected in shoots and leaves. This implies that there is a risk in the use of carbosulfan as a soil treatment or seed coating. © 2023 Society of Chemical Industry.
