“…It is necessary to understand that fish are constantly subjected to environmental stress (21,22) before planning EDC effect studies, including changes in temperature, hypoxia, sediment loads, flow rate, among others. To understand and to have the ability to extrapolate the effects observed in the individual organism with a chemical or mixture of chemicals having endocrine disruptive properties, cellular and physiological seasonal variations associated with changes in metabolic rates and fish reproductive status must be taken into consideration when evaluating the impacts on individuals and populations (9,21,33,(66)(67)(68)(69)(70)(71)(72)(73)(74)(75)(76)(77)(78)80).…”

“…This factor along with EDCs threat, have been neglected by aquatic ecologists in Chile, despite the fact that pollution is one of the five greatest threats to the diversity of freshwater systems ( 16 , 17 ). Similarly, the conservation status of most freshwater fish in Chile is poor, vulnerable or endangered, so the development of non-invasive/non-lethal tools for the effects of EDCs, such as VTG-like-phospholipoproteins in mucus ( 68 ) are an ideal approach.…”

“…Thus, Bahamonde et al. ( 68 ) demonstrated an increase in VTG-type phospholipoproteins (Vtg-like-phosphoproteins) in mucus on Percilia irwini exposed to wastewater from the Biobío River basin. Fish exposed to cellulose effluents as well as treated wastewater also showed an increase in these Vtg-like-phosphoproteins, similar to fish exposed to EE2 (10 ng/g).…”

Industrial wastewaters and urban discharges contain complex mixtures of chemicals capable of impacting reproductive performance in freshwater fish, called endocrine-disrupting compounds (EDCs). In Chile, the issue was highlighted by our group beginning over 15 years ago, by analyzing the impacts of pulp and paper mill effluents (PPME) in the Biobio, Itata, and Cruces River basins. All of the rivers studied are important freshwater ecosystems located in the Mediterranean region of Central Chile, each with a unique fish biodiversity. Sequentially, we developed a strategy based on laboratory assays, semicontrolled-field experiments (e.g., caging) and wild fish population assessments to explore the issue of reproductive impacts on both introduced and native fish in Chile. The integration of watershed, field, and laboratory studies was effective at understanding the endocrine responses in Chilean freshwater systems. The studies demonstrated that regardless of the type of treatment, pulp mill effluents can contain compounds capable of impacting endocrine systems. Urban wastewater treatment plant effluents (WWTP) were also investigated using the same integrated strategy. Although not directly compared, PPME and WWTP effluent seem to cause similar estrogenic effects in fish after waterborne exposure, with differing intensities. This body of work underscores the urgent need for further studies on the basic biology of Chilean native fish species, and an improved understanding on reproductive development and variability across Chilean ecosystems. The lack of knowledge of the ontogeny of Chilean fish, especially maturation and sexual development, with an emphasis on associated habitats and landscapes, are impediment factors for their conservation and protection against the threat of EDCs. The assessment of effects on native species in the receiving environment is critical for supporting and designing protective regulations and remediation strategies, and for conserving the unique Chilean fish biodiversity.

“…In relation to freshwater fish, the studies were conducted considering sampling sites from Choapa River, centralnorthern Chile (Ali et al, 2020); Maipo river basin, central Chile (Veliz et al, 2020;Vega-Retter et al, 2018); Itata river basin, central Chile (Bahamonde et al 2019;Chiang et al 2011;Orrego et al 2005Orrego et al , 2006Orrego et al , 2019.…”

“…The second most studied species was Trichomycterus areolatus Valenciennes 1848 with three publications (17% of articles related to fish) (Ali et al 2020;Orrego et al 2019;Chiang et al 2011). Percilia irwini Eigenmann 1928 is mentioned in two publications (Bahamonde et al 2019;Orrego et al 2019). The rest of the species studied were Basilichthys microlepidotus Jenyns 1841 (Veliz et al 2020;Vega-Retter et al 2018), Percilia gillissi Girard 1855 (Chiang et al 2011), Jordanella floridae Goode & Bean 1879, and Oryzias latipes Temminck & Schlegel 1846 (Orrego et al 2011b).…”

Compounds called endocrine disrupters (EDs) interfere with the endocrine systems of aquatic animals such as fish, amphibians, and mollusks. EDs impact sexual development and other functions that can affect the fitness of individuals with potential consequences to the population. We reviewed 45 studies published between 1999 and 2020 on the impact EDs have on aquatic species in Chile, including both indexed and non-indexed articles. The objective of this review is to identify geographic areas and organisms in which endocrine disruption has been detected, the alterations reported, and the compounds involved. We found 11 publications on marine mollusks, 17 on fish, and two on amphibians. Eight publications described bioassays, seven were related to environmental contamination including a review on monitoring the environmental effects of pulp and paper mill effluent (PPME). There is a worldwide concern about the endocrine disruption in aquatic species, however, this concern is still not considered in Chilean environmental regulations. The publications analyzed in this review demonstrate why Chilean environmental authorities should consider EDs in the regulatory process.
