“…The PNEC was set at 0.1 ng L -1 (0.1 ppt) for this compound. In a separate study in Israel, Barel-Cohen et al (2006) reported 10 ng L -1 (10 ppt) as the Lowest Observable Effect Level (the lowest concentration or amount of a substance found by experiment or observation that causes any alteration in morphology, functional capacity, growth, development, or life span of target organisms distinguishable from normal (control) organisms of the same species and strain under the same defined conditions of exposure) for estrogen (17β -E2 + estrone) due to the physiological effects on fish and plants.…”

h i g h l i g h t sBoth b-CD and CTAB could sensitize the fluorescence of EE2 and E2. Inclusion ratio of the complex was 1:1. Typical RTILs including [C n MIM]BF 4 and [C n MIM]PF 6 (n = 4, 6). The fluorescence lifetimes were 2.50-2.53 and 4.03-4.13 ns for EE2 and E2. The quenching process was demonstrated to be a dynamic quenching mechanism. g r a p h i c a l a b s t r a c tThe fluorescence lifetimes of EE2 were 2.50 and 4.13 ns, respectively, in water and methanol, and they increased gradually with increasing of b-CD concentrations. a r t i c l e i n f o t r a c tThis study investigated the steady-state and time-resolved fluorescence properties of 17a-ethinylestradiol (EE2) and 17b-estradiol (E2) in the presence of ordered media (b-cyclodextrins (b-CD) and cetyltrimethylammonium bromide (CTAB)). In addition, we analyzed the effects of four room temperature ionic liquids (RTILs) on the fluorescence intensities (FIs) of EE2/b-CD and E2/b-CD inclusion complexes in methanol. Both b-CD and CTAB enhanced the fluorescence of EE2 and E2. The FIs of EE2 and E2 with b-CD or CTAB in methanol were greater than those in water, possibly resulting from decreased oxygen-quenching in H 2 O molecules. b-CD and CTAB may form inclusion complexes with estrogen in both water and methanol. The inclusion ratio of the complex was 1:1 and the inclusion constant (K) values in water were greater than those in methanol. The fluorescence lifetimes were 2.50 and 4.13 ns for EE2 and 2.58 and 4.03 ns for E2 in aqueous solution and methanol, respectively. The changing trend of fluorescence lifetimes for EE2 and E2 in b-CD or CTAB was similar to the steady-state FIs. The four RTILs had a significant quenching effect on the FIs of EE2/b-CD and E2/b-CD, and the quenching process for EE2/ b-CD and E2/b-CD by RTILs was demonstrated to be a dynamic quenching mechanism. Fluorescent data obtained from these complex systems provide a theoretical foundation for understanding the interaction mechanisms between ordered media and RTILs in the analysis of estrogens.

“…According to the Environment Agency of the United Kingdom, the Predicted-No-Effect-Concentrations (PNEC) was 1 ng L −1 for 17␤-estradiol and 3-5 ng L −1 for estrone, while no PNEC is available for estriol [48]. Barel-Cohen et al [49] reported that 10 ng L −1 as the Lowest Observable Effect Level (LOEL) for total estrogen (17␤-estradiol + estrone). The results of this study are similar to previous reports by Mansell et al [20] and Yang et al [50].…”

h i g h l i g h t s• Hormones and metabolites were detected in runoff from test plots fertilized with cattle manure.• Composting can reduce the hormone concentration in manure compared to stockpiling.• About 10% of applied hormones can be lost through the dissolved phase of runoff. a r t i c l e i n f o a b s t r a c tRunoff generated from livestock manure amended row crop fields is one of the major pathways of hormone transport to the aquatic environment. The study determined the effects of manure handling, tillage methods, and rainfall timing on the occurrence and transport of steroid hormones in runoff from the row crop field. Stockpiled and composted manure from hormone treated and untreated animals were applied to test plots and subjected to two rainfall simulation events 30 days apart. During the two rainfall simulation events, detection of any steroid hormone or metabolites was identified in 8-86% of runoff samples from any tillage and manure treatment. The most commonly detected hormones were 17␤-estradiol, estrone, estriol, testosterone, and ␣-zearalenol at concentrations ranging up to 100-200 ng L −1 . Considering the maximum detected concentrations in runoff, no more than 10% of the applied hormone can be transported through the dissolved phase of runoff. Results from the study indicate that hormones can persist in soils receiving livestock manure over an extended period of time and the dissolved phase of hormone in runoff is not the preferred pathway of transport from the manure applied fields irrespective of tillage treatments and timing of rainfall.
