Effect of Heavy Metals on Chemoreception and Behavior of Crustaceans (a Review)

Ecotoxicological assessment of the effects of fluoxetine on Daphnia magna based on acute toxicity, multigenerational reproduction effects, and attraction-repellence responses

“…Abreu et al (2016) showed that Danio rerio (zebra fish) were attracted to concentrations of 25 and 50 μg/L of fluoxetine, but not at 1 μg/L; they assumed that the attraction was probably via olfaction as anosmic fish did not show this behaviour. Hence, the attraction effect produced by potentially toxic chemicals could be related to damage to chemoreceptors (Tierney et al, 2007;Cherkashin and Blinova, 2011). Another possible explanation might be that the reuptake of serotonin in the nervous system leads to a 'positive' effect on the organisms' behaviour, triggering an adverse reproduction response (Campos et al, 2016).…”

Not Only Toxic but Repellent: What Can Organisms’ Responses Tell Us about Contamination and What Are the Ecological Consequences When They Flee from an Environment?

“…For aquatic animals, such as fish and crustaceans, their interaction with the environment and their behavioral response to chemical signals are significantly mediated by sensory systems (e.g., gustation, chemosensory cells, olfactory epithelium at the gills, chemoreceptors in the antennulae, the olfactory nerve center of the suprapharyngeal ganglion, sensory bristles, and aesthetascs, for example) [ 50 , 84 , 85 ]. However, some contaminants like metals or pesticides can interfere with the sensorial process and affect the related behavioral response [ 50 , 86 , 87 , 88 , 89 , 90 ]. This interference can be caused by different mechanisms: direct exposure and damage to exposed olfactory neurons or the disruption in the expression of olfactory system-related genes [ 85 , 91 ].…”
