2022, Aquatic ToxicologyCitation Excerpt :Similar observations regarding Cd bioaccumulation were made by Buffet et al. (2014), where Cd concentrations significantly increased in worms, after 14 days of waterborne exposure at 10.0 μg Cd/L while no significant impairments of burrow kinetics were observed at this Cd treatment concentration. In H. diversicolor, burrowing behaviour is the most used quantifiable and reliable behavioural response to pollutants (Kalman et al., 2009; Bonnard et al., 2009; Mouneyrac et al., 2010; Buffet et al., 2014; Métais et al., 2019). According to our results, worms from low trace metal polluted systems such as M, will demonstrate clear impairments in burrowing behaviour when exposed to Cd toxicity, especially at the highest concentrations (Cd50 and Cd100), as opposed to worms originating from sites polluted by metals.

2022, Science of the Total EnvironmentCitation Excerpt :AChE plays an essential role in brain homeostasis by regulating ACh levels, directly influencing neuronal excitability and the release of other neurotransmitters (Bernardo et al., 2019). AChE has been recognized as a central biomarker of neurotoxicity (Métais et al., 2019). Induction and inhibition of its activity have been observed in laboratory and field studies in organisms exposed to pesticides, metals, polycyclic aromatic hydrocarbons, and pharmaceuticals (Chen et al., 2021b; Pullaguri et al., 2021; Ramesh et al., 2020; Severo et al., 2020; Xia et al., 2021).
