“…Hormone residues were found at the monitoring points considered in this study; the results are shown in Table 3. This presence could be attributed to the fact that near the inner bay of this lake there is an oxidation lagoon, which is inefficient in the degradation and/or removal of hormone residues and therefore, the poorly-treated water is being discharged into the lake (Torres et al, 2021).…”

“…Several studies have shown abnormal development of fish in water with hormone residues, such as the feminization of male fish, affecting reproduction and inducing vitellogenin production (Torres et al, 2021), growth of certain aquatic organisms (Sacdal et al, 2020), Therefore, it is important to consider toxicity concentrations in the life of the fish, taking into account the lipophilic nature of the hormones that collaborate with bioaccumulation; in Carassius auratus fish after 72 hours of dietary exposure containing 100 ng g -1 of EE2, the concentration was 1.7 ng g -1 ±0.29 (Al-Ansari et al, 2011).…”

“…Hormones are increasingly used around the world (Torres et al, 2021), such as the hormone 17 α-ethinylestradiol (EE2), which is one of the compounds in birth control pills (González-Hernando et al, 2013) as well as livestock; therefore, they are excreted by humans and animals (Fent, 2015) and are capable of interfering with the endocrine system in vertebrates and invertebrates (Bovier et al, 2018). Hormones such as estrone (E1) and estradiol (E2) are endogenous estrogens catalyzed by cytochrome P450 (CYP) enzymes which have biological activity in the liver, tissues, extrahepatic target cells, and extrahepatic target cells (Zhu & Lee, 2005), producing metabolites such as estrogen hydroxylation with a similar structure but with different physiological effects after metabolism in vivo (Xu et al, 2021).…”

“…because of the ineffectiveness of conventional treatments (Torres et al, 2021). Runoff from farms and effluent from sewage treatment plants are affected by these pollutants (Sacdal et al, 2020), and lakes collecting discharges from urban areas are affected these types of pollutants.…”

The presence of steroid hormones in lake waters causes contamination of aquatic ecosystems, which may cause endocrine alterations in the organisms that inhabit them. Moreover, many of these waters are purified and distributed to populations located around the lake. Therefore, these effects could be repeated in humans consuming the water. This study reports the presence of steroid hormone residues in the waters of the inner bay of Lake Titicaca and drinking water in the city of Puno (Peru). The solid phase extraction method was used for sample preparation, and the analyses were developed in an HPLC-DAD system. Results show maximum concentrations of steroid hormones estrone (E1) 1.56, 17 β- estradiol (E2) 2.27, 17 α- ethinylestradiol (EE2) 13. 88 ng L-1 respectively. These concentrations vary at the different monitoring points, and their presence could cause ecotoxicological effects to the endemic aquatic biota that inhabit this part of the lake. At the same time they also could affect the health of the human population that consumes this water

“…Recently, the ability of some techniques to remove ECs from water, such as advanced oxidation and adsorption has been discussed. For instance, estrogens removal rates vary between 100 µgL −1 to 10 mgL −1 in time periods that oscillate between 7 to 300 min with electrochemical advanced oxidation treatment [27]; however, these processes present a high cost and difficulty of implementation [1]. On the other hand, adsorption methods have the disadvantage that they only generate a phase transfer.…”

Among emerging pollutants, endocrine disruptors such as estradiol are of most concern. Conventional water treatment technologies are not capable of removing this compound from water. This study aims to assess a method that combines physicochemical and biological strategies to eliminate estradiol even when there are other compounds present in the water matrix. Na-montmorillonite, Ca-montmorillonite and zeolite were used to remove estradiol in a medium with sulfamethoxazole, triclosan, and nicotine using a Plackett–Burman experimental design; each treatment was followed by biological filtration with Daphnia magna. Results showed between 40 to 92% estradiol adsorption in clays; no other compounds present in the mixture were adsorbed. The most significant factors for estradiol adsorption were the presence of nicotine and triclosan which favored the adsorption, the use of Ca-montmorillonite, Zeolite, and time did not favor the adsorption of estradiol. After the physicochemical treatment, Daphnia magna was able to remove between 0–93% of the remaining estradiol. The combination of adsorption and biological filtration in optimal conditions allowed the removal of 98% of the initial estradiol concentration.

Steroids are a unique family of tetracyclic terpenoids that fulfill multiple functions vital to metazoan life. From unicellular fungi to higher plants and mammals, all eukaryotes depend on steroids to orchestrate multiple aspects of their growth, development, and reproduction. The wide array of biological activity of naturally occurring steroids has been exploited in developing therapeutic agents such as antihormones, anesthetics, immunomodulators, contraceptives, and antitumor agents. Nowadays, steroid pharmaceuticals are placed among the most marketed medical products and represent the second largest category next to antibiotics. Therefore, several industrial syntheses were developed for the efficient manufacture of structurally and stereochemically complex pharmaceuticals.
