“…Currently, given that organophosphates and metals are common pollutants in the environment, more research is needed to study the combined toxic effect of organophosphates and metals. , Both CPF and Cd had nephrotoxicity, − and the induction of oxidative stress is pivotal for their nephrotoxicity. , Generally speaking, additive responses, which means that the toxicity of combinations of chemicals equals to the sum of individual chemical response, would be expected . Although no statistical interaction was present between the CPF and Cd in kidney, the combination of CPF and Cd was still less toxic than the sum of the two chemicals alone.…”

Cadmium (Cd) and chlorpyrifos (CPF) often coexist in the environment and induce combined toxicity to organisms. Here we studied the combined nephrotoxicity of environmentally relevant low doses of Cd and CPF. We treated the mice for 90 days with different doses of Cd and CPF and their mixtures via oral gavage. Then histopathological evaluation and biochemical analysis for kidney tissues were carried out. The change of metabolites in kidney was detected by using a metabolomics approach using GC-MS. We found that Cd, CPF, and their mixtures caused oxidative damage as well as disturbance of renal amino acid metabolism. We identified potential metabolite biomarkers in kidney, which included acetic acid for CPF treatment, glycerol and carboxylic acid for Cd treatment, and l-ornithine for the mixture of CPF and Cd treatment, respectively. In addition, we found that Cd promoted the metabolism of CPF in kidney. This may contribute to the result that the toxicity of the mixtures was lower than the sum of the toxicities of Cd and CPF alone. In conclusion, our results indicated that CPF and Cd could disrupt the kidney metabolism in rats even when they were exposed to a very low dose of CPF and Cd.

“…The most accessible forms of metals for benthic organisms are those dissolved in the pore water of sediments [ 70 ]. A study [ 71 ] explored how Cd 2+ and Cu 2+ ions affect the sorption of atrazine, a common herbicide, by bottom sediments. The research revealed that Cd enhances the sorption of atrazine synergistically, while Cu has an antagonistic effect.…”

The article discusses the issue of extensive use of detergents and sanitizers in the time of new challenges associated with the COVID-19 (SARS-CoV-2) pandemic. These agents could pose threats to the existence of free-living invertebrates as essential components of the ecosystem. The biological effects of the mentioned classes of substances, their metabolites, and combined effects in the mixture have not been studied enough. The main challenges in trying to balance the threats and benefits of using such substances are the lack of knowledge of the biological effects of these products, the gaps in testing invertebrates’ responses, and changes in environment-related regulations to minimize risks to animals and humans. Numerous studies in this field still leave research gaps, particularly concerning the combined toxicity of well-known and widely used disinfectants, surfactants, and heavy metals, posing potential future challenges. Additionally, the review identified the need for additional testing of invertebrates for their sensitivity to disinfectants and surfactants of different compositions, including improved (non-invasive) methods, studies for early life stages, and comparative studies of species resilience.

“…It has been demonstrated that a combined pollution of pesticides with metals in soil could lead to deleterious effects on microbial communities due to toxic synergistic effects (Dewey et al 2012;Olaniran et al 2013). Moreover, the presence of metals in soil may affect the behavior of pesticides, increasing or decreasing their sorption, and therefore their bioavailability (Leistra and Matser 2004;Li et al 2011;Qian et al 2011;Pei et al 2014). In this sense, it has been reported that copper promotes the adsorption of carbendazim or iprodione (Leistra and Matser 2004) and causes antagonistic effects on atrazine sorption (Qian et al 2011).…”

Today, metal nanoparticles are being incorporated into soil through several routes, where they could alter the sorption behavior of other contaminants such as pesticides. Therefore, a short assay was carried out through sorption isotherms to evaluate the effect of copper nanoparticles (NCu) and copper sulfate (as the bulk form) at 50, 100, and 200 mg kg −1 on the sorption capacity of two commonly applied fungicides (carbendazim and iprodione) onto two agricultural soils, contrasting in organic matter content (2% and 14%) and texture (sandy and loamy) respectively. The isotherms were well described using the Freundlich model (R 2 > 0.95). Interestingly, at low organic matter, the pesticide sorption was notoriously increased in the presence of copper. However, NCu caused a minimal dose-dependent effect compared with their bulk form. Conversely, at high organic matter, the sorption was slightly altered by the presence of NCu. These findings constitute the first evidence that copper nanoparticles applied to agricultural soils can modify the sorption behavior of fungicides, which might increase their permanence in the environment. However, more detailed studies should be carried out in order to understand the interaction mechanisms between NCu/pesticides/ soil and consequently their potential environmental risks.
