“…BiagiantiRisbourg and Bastide (1995) have shown an increase in HSI due to the sequestration of fat-soluble pesticides in liver lipid droplets. Other authors suggested that liver may swell with pesticide exposure in order to increase its detoxification capacity (Arnold et al 1995;Bacchetta et al 2014) or in consequences of degenerative changes in the liver tissue (Arnold et al 1995;Guardiola et al 2014). The absence of classic dose/response relationship may have so three reasons: (1) different modes of action of pesticides at different concentrations, including a low-dose effect for the endocrine active substances (i.e., atrazine or S-metolachlor) (EFSA 2010), (2) different physiological responses-or strategies-depending on the concentration of toxic substances, or (3) the passage of a metabolic compensation state to a non-compensation state when stress becomes too severe (Sokolova 2013).…”

Crossed effects between climate change and chemical pollutions were identified on community structure and ecosystem functioning. Temperature rising affects the toxic properties of pollutants and the sensitiveness of organisms to chemicals stress. Inversely, chemical exposure may decrease the capacity of organisms to respond to environmental changes. The aim of our study was to assess the individual and crossed effects of temperature rising and pesticide contamination on fish. Goldfish, Carassius auratus, were exposed during 96 h at two temperatures (22 and 32 °C) to a mixture of common pesticides (S-metolachlor, isoproturon, linuron, atrazine-desethyl, aclonifen, pendimethalin, and tebuconazol) at two environmentally relevant concentrations (total concentrations MIX1 = 8.4 μg L(-1) and MIX2 = 42 μg L(-1)). We investigated the sediment reworking behavior, which has a major ecological functional role. We also focused on three physiological traits from the cellular up to the whole individual level showing metabolic status of fish (protein concentration in liver and muscle, hepatosomatic index, and Fulton's condition factor). Individual thermal stress and low concentrations of pesticides decreased the sediment reworking activity of fish and entrained metabolic compensation with global depletion in energy stores. We found that combined chemical and thermal stresses impaired the capacity of fish to set up an efficient adaptive response. Our results strongly suggest that temperature will make fish more sensitive to water contamination by pesticides, raising concerns about wild fish conservation submitted to global changes.

“…Crustaceans are particularly sensitive to endosulfan. It is known that this pesticide is highly toxic to many lobster and shrimp species, with average lethal concentrations (LC50) close to 1 μg•L -1 [24]. Molluscs have been selected as monitoring species for their sessile and sedimentary lifestyle, and their ability to integrate environmental contamination in time and space [25].…”

“…The organophosphate insecticides have been shown to exert lethal effects on some species of fishes and other aquatic fauna (Bacchetta et al, 2014). Since rohu is one of the major carp and economical backbone of the aquaculture industry in India, the present paper is oriented towards studying the lethal effects of propenofos on vital organs of the rohu fish (Labio rohita) in laboratory conditions in order to understand the deleterious effects of the propenofos.…”
