“…Testosterone levels were slightly decreased in treated E. vermiculata snails and this may be due to the inhibitory effects of the drug on the ovarian and adrenal androgens synthesis and/or increasing levels of sex hormones-binding globulin ( Zimmerman et al., 2014 ). This finding is in agreement with Ibrahim and Sayed (2019) who found that the level of T hormone was decreased significantly in the gonad tissue of B. alexandrina treated with sub-lethal concentrations of some herbicides. Atrazine and glyphosate are toxic to Sertoli cells in mature rat and induced apoptosis at higher doses in germ cells ( Clair et al., 2012 ).…”

“…Similarly, Omran and Salama (2016) found that E2 level decreased in gonadal tissue of Biomphalaria alexandrina snails treated with sublethal concentrations of atrazine and glyphosate herbicides for 3 weeks. In accordance with this finding, Ibrahim and Sayed (2019) found that the level of E2 hormone were decreased significantly in the gonad tissue of the snail Biomphalaria alexandrina after exposure to sub-lethal concentrations of oxyfluorfen and attributed this decrease to the disturbance in the reproductive hormones. Progesterone (PRG) is a steroid sex hormone involved in embryogenesis of humans and other species and plays an important role in brain functions ( Baulieu and Schumacher, 2000 ; Li et al., 2012 ).…”

“…Biomphalaria species are considered to be good indicators of environmental contamination, and have been analyzed to determine the bioaccumulation of heavy metals and metabolic shifts provoked by contact with herbicides and molluscicides (15)(16)(17). In particular, the herbicide oxyfluorfen can damage the reproductive and antioxidant systems of Biomphalaria species, as well as having cytotoxic and genotoxic effects (18,19). The results of the present study demonstrated a more pronounced intraspecific pattern in B. glabrata (85%), when individuals from the same population collected in the field and raised in the laboratory were compared.…”

Near Infrared Spectroscopy (NIRS) is a spectroscopic technique that evaluates the vibrational energy levels of the chemical bonds of molecules within a wavelength range of 750–2,500 nm. This simple method acquires spectra that provide qualitative and quantitative data on the chemical components of the biomass of living organisms through the interaction between the electromagnetic waves and the sample. NIRS is an innovative, rapid, and non-destructive technique that can contribute to the differentiation of species based on their chemical phenotypes. Chemical profiles were obtained by NIRS from three snail species (Biomphalaria glabrata, Biomphalaria straminea, and Biomphalaria tenagophila) that are intermediate hosts of Schistosoma mansoni in Brazil. The correct identification of these species is important from an epidemiological viewpoint, given that each species has distinct biological and physiological characteristics. The present study aimed to develop a chemometric model for the interspecific and intra-specific classification of the three species, focusing on laboratory and field populations. The data were obtained from 271 live animals, including 150 snails recently collected from the field, with the remainder being raised in the laboratory. Populations were sampled at three localities in the Brazilian state of Rio de Janeiro, in the municipalities of Sumidouro (B. glabrata) and Paracambi (B. straminea), and the borough of Jacarepaguá in the Rio de Janeiro city (B. tenagophila). The chemometric analysis was run in the Unscrambler® software. The intra-specific classification of the field and laboratory populations obtained accuracy rates of 72.5% (B. tenagophila), 77.5% (B. straminea), and 85.0% (B. glabrata). The interspecific differentiation had a hit rate of 75% for the field populations and 80% for the laboratory populations. The results indicate chemical and metabolic differences between populations of the same species from the field and the laboratory. The chemical phenotype, which is closely related to the metabolic profile of the snails, varied between environments. Overall, the NIRS technique proved to be a potentially valuable tool for medical malacology, enabling the systematic discrimination of the Biomphalaria snails that are the intermediate hosts of S. mansoni in Brazil.

Enzyme activity and endocrine disruption markers are also common endpoints both regarding the soil (Ibrahim et al 2019) and the aquatic biota (Windsor et al 2018;Li et al 2016). Whether the responses of C. elegans compare to those by other model species typically used in ERA will be appraised in the following section of this manuscript.…”

in the context of the Fulbright program. Her research has been focused on the toxic effects of pesticides to aquatic and soil organisms, considering both single and mixture exposures to these environmental contaminants widely used in the agricultural practices to increase food production. The applicability of mixture toxicity models as a tool to design environmental friendlier formulations of pesticides has been her general research line. The regulation that controls the use of pesticides is also one of her main interests. The understanding and improvement of the Environmental Risk Assessment schemes that are used to assess the risk that these products can pose to the environmental and human health is imperative and gave rise to the writing of this paper. Joana Luísa Pereira is a researcher at the Department of Biology and the Centre for Environmental and Marine Studies (CESAM) University of Aveiro since her PhD in Biology, awarded in 2008. Her main research lines are within the fields of ecotoxicology and environmental risk assessment, with strong links to limnology (including under regulatory frameworks such as the EU-Water Framework Directive), extreme environments, invasive species and aquatic nuisance management and education for sustainability. She has been investing in the development of new approaches and testing platforms towards the improvement of prospective and retrospective environmental risk assessment routines, always aiming for the increase of environmental realism and/or better prediction capabilities. Pesticides, metal elements and designer chemicals have been the major contaminants focused within this prospective context. She published so far more than 60 SCI papers, collecting more than 800 citations.
