“…With the use of an autosampler, automation was even achieved [41]. Mitani applied this automatic technique to the determination of five estrogens in environmental water samples using a Supel-Q porous layer open tubular (PLOT, porous divinylbenzene polymer) capillary column as the extraction medium [35]. Recently, we proposed a new poly(acrylamide-vinylpyridine-N,N -methylene bisacrylamide) monolithic capillary column for in-tube SPME-HPLC, and it also performed successful extraction of bisphenol A (BPA) and 17␣-ethinylestradiol (EE2) [21,42].…”

“…This observation is supported by finding reported by Williams et al (2007), Kolok et al (2007), Yuan et al (2014) AND Huang et al (2016), Animal farms are potential sources of natural and synthetic estrogens. In addition, several studies reported that WSPs are potential sources of estrogens pollution in rivers (Mitani et al, 2005;Gomes et al, 2003;Sim et al, 2011;Belhaj et al, 2014). The main source of EE2 in rivers could be the use of contraceptive by residents in domestic/commercial houses (Lei et al, 2009;Laurenson et al, 2014).…”

“…Several studies in Europe, Asia and USA have reported that sewage effluents are major contributors of manmade chemical pollution in rivers (Gomes et al, 2003;Mitani et al, 2005;Huerta et al, 2016). On the other hand, runoff associated with waste from animal farming has been reported as another potential source of estrogens in the rivers (Williams et al, 2007;Kolok et al, 2007;Yuan et al, 2014;Huang et al, 2016).…”

This study aimed to assess the extent of pollution of aquatic ecosystems by endocrine disrupting estrogens particularly the ethinylestradiol (EE2), estrone (E2) and estradiol (E1). The study was carried out in Morogoro urban and peri-urban areas. The main sources of fresh water for domestic uses, fishing and agricultural activities in the study areas including the Mindu dam catchment area, Ngerengere and Morogoro Rivers were assessed. The endocrine disrupting estrogens in water samples were identified and quantified using competitive Enzyme Linked Immunosorbent Assay (ELISA) kits. The recovery of estrogens in this study ranged from 65 to 90.22%, the range which is within the acceptable level. The levels of estrogens in Ngerengere River ranged from non-detectable levels to 0.68, 0.03 to 8.42 and 0.05 to 16.97 ng/L for EE2, E2 and E1, respectively. At Mindu Dam the levels ranged from 0.07 to 0.3 ng/L, 0.41 to 2.1 ng/L and 2.6 to 6.5 ng/L for EE2, E2 and E1 respectively. Furthermore, for Morogoro River the levels ranged from undetected to 0.92, 0.34 to 9.53 and 0.17 to 11.49 ng/L for EE2, E2 and E1 respectively. Mean concentrations in control samples and those in upstream and midstream of the rivers were comparable (p > 0.05). But the mean concentrations in downstream portions were significantly higher than those in control samples (p < 0.05). These concentrations however, were below those reported in other studies to cause harmful health effects. Hence, the extent of pollution was not significant enough to cause adverse health effects to aquatic organisms and human.

“…Due to their stability most of the hormones are excreted unchanged or as active metabolites. Most commonly used processes are based on the extraction of hormones from a sample matrix and analysis by liquid chromatography (Mitani et al, 2005;Yi et al, 2007). Analysis by GC-MS could however be faster, but the hormones require derivatization to make them more volatile.…”
