Environmental quality and ecotoxicity of sediments from the lower Salado River basin (Santa Fe, Argentina) on amphibian larvae

High toxicity of agro‐industrial wastewater on aquatic fauna of a South American stream: Mortality of aquatic turtles and amphibian tadpoles as bioindicators of environmental health

“…In general, pesticide concentrations found in our study were relatively lower than those found in other matrices of the same region (e.g., Lajmanovich et al, 2023; Peluso et al, 2022). It is interesting that both SCC and LTS contain various pesticides that might be runoff from the surrounding crops.…”

“…Atrazine is a ubiquitous herbicide that is widely used in crops such as corn and sorghum. It was detected in all point sites here studied, and it was already recorded in several streams and rivers from Argentina (Alonso et al, 2018; Peluso et al, 2022; Pérez et al, 2017) and one explanation is that atrazine and other two herbicides, 2,4‐D and glyphosate, are the most used pesticides in transgenic crops. In this sense, 2,4 D was also detected in both sites of study.…”

“…It is well known that interactions or synergies between several mixtures of nutrients, pesticides, organic matter, and industrial effluents produce genotoxicity in amphibian tadpoles, increasing their MN frequency (e.g., Benvindo‐Souza et al, 2020; Peltzer et al, 2013; Peluso et al, 2022). The increase in MN frequency in tadpoles exposed to SCC treatment indicates genotoxicity, which may be a consequence of the direct interaction of various contaminants (nutrients, pesticides) and physicochemical parameters with DNA or indirect mechanisms such as oxidative stress (Lajmanovich et al, 2015; Pérez‐Iglesias et al, 2020).…”

“…A recent research in Santa Fe Province detected 30 pesticides (insecticides, herbicides, and fungicides) in all water and sediment samples from one of its rivers (Salado River). For instance, higher concentrations of glyphosate and its metabolite AMPA and glufosinate were recorded in this river (Lajmanovich et al, 2023; Peluso et al, 2022).…”

Water and sediment quality of an agro‐industrial area through different approaches: Physicochemical parameters and ecotoxicity with amphibians

“…Moreover, a third of the planet's endangered species are amphibians, and they are the most vulnerable group among the world's vertebrates (IUCN, 2022). In this sense, the chemical contamination of their aquatic habitats is an important factor that causes this decrease (Egea‐Serrano et al, 2012), especially by the effluent of agro‐industrial environments (Ali et al, 2011; Peluso, Aronzon, et al, 2022). This vulnerability is a direct consequence of skin permeability (Blaustein et al, 2003), and their biphasic life cycle, mostly associated with aquatic environments (Kerby et al, 2010).…”
