“…Estrogens have been found in water samples (Table 4) at low ng L −1 concentra-tions but they represent a greater risk for non-target organisms as already proved. For example, 17�-estradiol was detected in rivers [23,[160][161][162][163] at levels ranging from 0.6 to 100 ng L −1 and in STP effluents at concentrations between 0.3 [160] and 85 ng L −1 [89]. Ethinylestradiol was also found in surface waters in the US (73 ng L −1 ) [23] and Italy (the Tibre river) at 1 ng L −1 [163].…”

Pharmaceuticals are biologically active and persistent substances which have been recognized as a con-tinuing threat to environmental stability. Chronic ecotoxicity data as well as information on the current distribution levels in different environmental compartments continue to be sparse and are focused on those therapeutic classes that are more frequently prescribed and consumed. Nevertheless, they indicate the negative impact that these chemical contaminants may have on living organisms, ecosystems and ultimately, public health. This article reviews the different contamination sources as well as fate and both acute and chronic effects on nontarget organisms. An extensive review of existing data in the form of tables, encompassing many therapeutic classes is presented.Keywords: Pharmaceuticals, Sources, Environmental fate, Ecotoxicological effects

“…This method not only saves sample preparation time, reduces solvent and sample consumption, but also can lower the detection limit. Coupled with GC [13][14][15][16] or HPLC [19,22], fiber-SPME has been successfully applied to the extraction and determination of several EDCs from environmental samples. Moreover, a new SPME-HPLC system, known as in-tube SPME, was developed by Eisert and Pawliszyn in 1997 using an inner-wall coated capillary as the extraction medium [40].…”

“…Halaz guztiz ere, hainbat lanetan aipatu da araztegiak ez direla gai konposatu kimiko guztiak ezabatzeko [22][23][24][25]. Araztegiak sortu ziren garaian, gaur egun ezagutzen diren hainbat konposatu organiko ez ziren ezagutzen, eta, ondorioz, araztegietan egiten diren tratamenduak ez dira gai konposatu organiko guztiak arazteko, ez baitago tratamendu espezifikorik oraindik ere indarrean.…”

Laburpena: Ingurumeneko uretan kutsatzaile organiko desberdinak aurkitzen dira, nahiz eta kontzentrazio baxuetan izan (ng/L mailan). Araztegien irteera korronteak izan ohi dira konposatu horien iturririk nagusietako bat, araztegiek erabiltzen dituzten mekanismoak ez baitira gai kutsatzaileen arazketa osoa burutzeko. Horien artean, konposatu disruptore endokrino (EDC) izenez ezagutzen diren konposatuak aurki daitezke, eta horiek ingurumenean bizi diren espezieetan aldaketa endokrinoak sor ditzakete, nahiz eta EDCak kontzentrazio baxuetan egon. Kalte horien artean, malformazioak, populazioen aldaketak edo intersexualitatea dira nabarmenenak. Hau guztia ikusirik, kimika analitikoaren ikuspuntutik oso garrantzitsua da metodo analitiko sentikorrak garatzea konposatuak ur-eta biota-laginetatik erauzi eta garbitzeko, bai eta konposatuek biotaren atal desberdinetan metatzeko duten joera aztertzeko ere.Hitz gakoak: konposatu disruptore endokrinoak, erauzketa-metodoak, biokontzentrazioa, ur-laginak, biota.Abstract: There are several organic contaminants present in the aquatic environment, even they are find at very low concentrations (ng/L level). The effluents of the wastewater treatment plants (WWTP) can be one of the main sources into the environment, since the mechanism used by the WWTP are not fully efective for the complete removal of the contaminants. Among them, some of them are classified as endocrine disrupting compounds (EDCs) and they can provoke endocrine alterations in the species habiting in the water even they are found at low concentrations. Malformations, a decrease on the polulation or intersexuality are the most significant damages. Thus, the development of highly sensitive analytical methods for the extraction and clean-up of the water and biota samples is vital from an analytical point of view together with the accumulation capacity of the compounds in the different biota compartments.
