“…When sprayed on crops, a fraction of applied pesticides may reach surface and/or groundwater through runoff, drainage or drift, potentially altering aquatic ecosystems health and drinking water quality (Schäfer et al, 2011). A number of recent studies have, indeed, revealed the presence of a variety of pesticide residues in fish, surface waters, groundwater, sediments, soils and rainwater of the Pampa region (Peruzzo et al, 2008, Aparicio et al, 2013, Bonansea et al, 2013, De Gerónimo et al, 2014, Lupi et al, 2015, Hunt et al, 2016, Ronco et al, 2016, Etchegoyen et al, 2017, Pérez et al, 2017, MacLoughlin et al, 2017, Primost et al, 2017, Brodeur et al, 2017, Castro Berman et al, 2018, Alonso et al, 2018.…”

“…Beyond these community indices, morphometric indices are used frequently to estimate fish general health (growth, nutritional state and energy content) under the assumption that morphometric changes track to physiological changes (Sutton et al, 2000). These kind of indices, like body condition indices or condition factors, are common indices in pollution effect studies (i.e., Brodeur et al, 2017). More particularly, histopathological indices (Maggioni et al, 2012) and fish somatic indices that relate the weight of determined tissues (i.e.…”

Integrated Biomarkers Response (IBR) index have been developed as a practical and robust tool to assess the susceptibility to pollutants using multiple biomarker responses. Neonicotinoid insecticides are nowadays one of the most sold pesticides worldwide. Nevertheless, imidacloprid (IMI) sub-lethal effects such as oxidative stress (OS) on fishes are scarcely studied. Hence, the aims of this work were: (1) to evaluate exposure-and damage biomarkers related to OS in the freshwater fish Australoheros facetus exposed to IMI and (2) to apply the IBR index to achieve a comprehensive understanding of OS in the fish. The results of the present study showed that all the biomarkers presented different responses in the three monitored tissues: liver, brain and gills. Results for an initial battery of 19 biomarkers were obtained and for the IBR index only those with significant differences have been considered. The biomarkers that had the most important weight on the IBR index were SOD activity in brain and gills, H 2 O 2 concentration in liver, and carbonyl groups concentration in gills in fishes exposed to 100 and 1000 μg L −1 IMI. This index allowed affirming that a short term exposure to environmentally relevant concentrations of IMI (≥10 μg L −1) produces OS in A. facetus. However, a more deep understanding of some biomarkers response is necessary to improve the index and for finally apply it in field studies.

“…Approximately 14% of the values listed in Table 3 had a concentration >1.00 μgL -1 . Additionally, the ndings of dichlorvos in freshwater organisms from Argentina and Belgium indicate not only its presence in water bodies but also the presence in biological matrices [60,61].…”

During the last years, dichlorvos has had an extremely high occurrence in monitoring campaigns, showing concentrations that would result in severe environmental impact. Environmental quality concentrations (EQC) for dichlorvos in surface waters vary by more than two orders of magnitude among different regulations. Regulatory EQC-values are based on toxicity data where species sensitivity distributions (SSDs) are mostly used as a basis. Hence, what makes the difference between the different national and regional EQC-values? And will they all protect the aquatic fauna? To investigate these questions, we constructed an SSD based on our laboratory data and compared this with SSDs based on literature data for technical and formulated products and species of different taxa. Finally, we compared the SSD-derived EQCs with a meta-study on monitored environmental concentrations to determined the EQC-exceedance. The following hypotheses were tested: (i) formulated dichlorvos will result in lower EQCs, as formulated products may include synergists; (ii) different taxon will have different sensitivities with arthropods being the most sensitive group; (iii) environmental concentration of dichlorvos represents a risk for aquatic organisms. As a result, experimental SSD defined a protective concentration of 6.5 ng L-1 for 5% of the species, which is in line with the European limit values, but one to two-fold lower than the limit values of the USA, China, and Argentina. The EQCs of three of the four regions included in this study are therefore not enough to protect the aquatic fauna.
