“…Therefore, investigation of the effect of commercial pesticides on nontarget organisms can provide very realistic reports [39]. Many bioassays with aquatic organisms have shown that invertebrates are generally more sensitive to xenobiotics than vertebrates [10].…”

“…Invertebrates are organisms that are widely distributed, represented by many species, and occupy lower levels of the trophic chain. Many bioassays that use aquatic invertebrates have shown that they are more sensitive to xenobiotics than aquatic vertebrates [10]. Many xenobiotics are transferred from invertebrates to vertebrates through accumulation by nutrition.…”

In the present study, we determined the 24, 48, 72, and 96 h LC50 values for a glyphosatebased commercial herbicide (GBH) for the aquatic snail Melanopsis praemorsa. We examined subacute toxicity responses from M. praemorsa after 30-day exposure to 1/10, 1/5, and 1/2 of the 96 h LC50 value using several biochemical markers. Glutathione reductase (GR) and glutathione S-transferase (GST) activities were significantly inhibited when compared to control after 4 days of GBH exposure. On the twentieth day of exposure, GST and GR activities were inhibited in organisms exposed to both LC50/10 and LC50/5 compared to control. These results showed that chronic GBH exposure inhibited GST, an important detoxifying enzyme. GR, an important oxidative stress marker, was likely inhibited as a result of inhibition of the detoxification mechanism.

This review includes works published in the general scientific literature during 2010 on the effects of anthropogenic pollutants on freshwater organisms. It begins with two broad sections: research reviews and broad field studies and surveys. This is followed by reviews of research categorized in sections to reflect the pollutant class. These sections include wastewater, stormwater and non‐point source pollution, nutrients, sediment cap materials and suspended clays, botanical extracts, surfactants, metals, persistent organic pollutants, pharmaceuticals, endocrine disruptors, pesticides, petroleum hydrocarbons and polycyclic aromatic hydrocarbons (PAHs), ionic liquids, and nanomaterials. The final section includes works describing innovations in the field of freshwater pollution research.

“…Moreover, this species was recently validated for use in ecotoxicity assessments (Achiorno et al, 2010). The aim of the present work was therefore to evaluate the effect of the fungicide CBZ on C. nobilii (test species) based on the hypothesis that the environmentally acceptable concentrations alter the normal development and, in turn, influence the infectivity and abundance of C. nobilii in aquatic habitats.…”

“…The Gordiida, in general, act as a link between the taxa of freshwater and terrestrial ecosystems, while C. nobilii in particular is highly vulnerable to pesticides other than CBZ, as well as to a herbicide and an insecticide, even at environmentally allowable concentrations (Achiorno et al , 2008, 2009). Moreover, this species was recently validated for use in ecotoxicity assessments (Achiorno et al , 2010). The aim of the present work was therefore to evaluate the effect of the fungicide CBZ on C. nobilii (test species) based on the hypothesis that the environmentally acceptable concentrations alter the normal development and, in turn, influence the infectivity and abundance of C. nobilii in aquatic habitats.…”

Susceptibility of preparasitic stages of Chordodes nobilii (Gordiida, Nematomorpha) to the fungicide carbendazim

We evaluated the effect of carbendazim on non-target organisms using the parasite Chordodes nobilii as a test organism. The Gordiida act as a link between freshwater and terrestrial ecosystems; and C. nobilii, a neotropical representative species of this group, has been shown to be sensitive to other contaminants even at environmentally acceptable concentrations. The taxa susceptible to carbendazim, however, may not be adequately represented among the standard aquatic test species used in ecotoxicological risk assessment. Moreover, the autochthonous organisms in this area that could be used as bioindicators still need to be found. The aim of the present work was therefore to assess the susceptibility of the preparasitic stages of C. nobilii to noxious effects by carbendazim. The assay protocol consisted in 96- and 48-h acute exposures of early embryonic stages and larvae, respectively, to concentrations ranging from 10 to 360 μg/l. Embryonic development was not inhibited by carbendazim at any of the evaluated concentrations, but the infectivity of larvae emerging from the exposed eggs was significantly diminished. Larval survival rate was also affected at the lowest concentration assayed. Values of the mean inhibition concentration (IC50) were 7 and 11 μg/l for embryos and larvae, respectively. Compared to other freshwater organisms, C. nobilii can be considered a species moderately to highly susceptible to carbendazim. As the expected environmental concentrations of carbendazim range from 6.25 to 41.3 μg/l, C. nobilii could well be a species in danger when exposed to this fungicide.
