“…Thus, we cannot provide a clear picture of the potential risks to the aquatic environment. According to Gorga et al (2014), each steroid estrogen possesses different estrogenic potencies in an aquatic environment. The effects of mixtures and the persistence of these estrogenically active substances should be considered (Esteban et al 2014).…”

“…Environmental contaminants that can disrupt the endocrine system in humans and wildlife are known as endocrine-disrupting compounds (Esteban et al 2014;Wang et al 2009). By contrast, less information is available on estrogenic compounds with hormonedisrupting activities.…”

“…Even low concentrations of steroid estrogens in rivers could alter normal hormone function in humans and wildlife, as observed in the Tiber River in Italy (Laganà et al 2004), Songhua river, China (Zhang et al 2014), and the Iberian River (Gorga et al 2014). Steroid hormones have lipophilic characteristics with high octanol-water partition coefficient values (high log Kow 2.81-5.67).…”

The occurrence and estrogenic activities of steroid estrogens, such as the natural estrone (E1), 17β estradiol (E2), and estriol (E3), as well as the synthetic 17α-ethynylestradiol (EE2), were investigated in eight sampling points along the Langat River (Malaysia). Surface water samples were collected at 0.5 m and surface sediment 0-5 cm from the river surface. Instrument analysis of steroid estrogens was determined by UPLC-ESI-MS with an ultra-performance liquid chromatograph (Perkin Elmer FX15) coupled to a Q Trap function mass spectrophotometer (model 3200: AB Sciex). Steroid estrogen concentrations were higher in the Langat River sediments than those in its surface water. In surface water, E1 was not detected in any sampling point, E2 was only detected in two midstream sampling points (range 0-0.004 ng/L), E3 in three sampling points (range 0-0.002 ng/L), and EE2 in four sampling points (range 0-0.02 ng/L). E1 and E2 were detected in sediments from all sampling points, E3 in five sampling points, while EE2 only in one midstream sample (3.29E-4 ng/g). Sewage treatment plants, farming waste, and agricultural activities particularly present midstream and downstream were identified as potential sources of estrogens. Estrogenic activity expressed as estradiol equivalents (EEQs) was below 1 ng/L in all samples for both surface water and sediment, indicating therefore a low potential estrogenic risk to the aquatic environment. Although the health risks are still uncertain for drinking water consumers exposed to low levels of steroid estrogen concentrations, Langat River water is unacceptable for direct drinking purposes without treatment. Further studies of endocrine disruptors in Malaysian waters are highly recommended.

“…poluição do ecossistema aquático é um assunto alvo de um grande número de pesquisas, devido à necessidade e escassez da água potável (GORGA et al, 2015). Com o crescimento da economia e desenvolvimento urbano, um grande número de rios enfrenta sérios problemas de poluição, proveniente, principalmente, da indústria, agricultura, hospitais e residências (HUANG et al, 2015;KUMAR et al, 2014).…”

“…Essas substâncias, apesar do potencial dano que podem causar ao ecossistema aquático, não apresentam legislação específica, ou seja, não são regulamentadas (JARDIM et al, 2012). A presença de estrogênios em ambientes aquáticos pode causar inúmeros problemas à biota, como feminilização, infertilidade e anomalias físicas em peixes (BELHAJ et al, 2015;GORGA et al, 2015;HUANG et al, 2015). Devido aos problemas desencadeados pela presença desses micropoluentes, atualmente são desenvolvidos inúmeros métodos para a remediação e monitoramento dos mesmos no ambiente aquático (GAVRILESCU et al, 2015;LI et al, 2014).…”

Endocrine disrupting chemicals (EDCs) are detected in environmental matrices such as surface water, wastewater, groundwater, and drinking water in the ng/L range. For environmental sediments, values in the range of ng/g and even lower are reported. These almost omnipresent low concentrations of estrogens are of major concern, in particular as sorption parameters derived from laboratory investigations tend to imply the absence of estrogens in the natural environment. Very few studies consider the fate and transport of estrogens in column tests at environmentally relevant concentrations, including metabolite formation and sorption. Also, the effect of input concentration on hormone degradation is unclear. To close this gap, the estrogens 17ß‐estradiol (E2), estrone (E1), and the conjugated estrogen estrone‐sulfate (E1‐3S) were each injected into saturated, packed soil columns as pulses with subsequent analysis of soil and aqueous samples. The transformation pathway E2 to E1 and subsequently to E1‐3S was verified in sandy clay loam soil from Bet Dagan, Israel. Furthermore, it was shown that (i) E2 is rapidly degraded in soil and transformed in soil to E1; (ii) E1 is subject to strong retardation by sorption; and (iii) E1‐3S behaves almost conservatively and shows the lowest sorption and transformation potential.
