“…The Hangbu River runs across the suburban district of Hefei City, with a large amount of adjacent agricultural land. Estrogens in animal manure can be transported into rivers and lakes (Guardian & Aga, 2019). Therefore, it is likely that untreated animal manure applied to farmland was the primary source of residual estrogens in the Hangbu River.…”

Antibiotics and estrogens are recognized as emerging contaminants in the water environment because of their potentially adverse effects on aquatic ecosystems. The concentrations of four steroid estrogens (17α-estradiol, 17βestradiol, estrone, and estriol) and eight antibiotics (norfloxacin, levofloxacin, ciprofloxacin, enrofloxacin, metronidazole, sulfapyridine, doxycycline, and sulfamethoxazole) in the Chaohu Lake basin in Anhui province, China, were analyzed along with adjacent wastewater. The levels of the target antibiotics and estrogens were below detection limits (not detected [nd])-89.86 and nd-118.09 ng L −1 , respectively, in the lake water. All of the target antibiotics and estrogens were detected in sediment, and the concentrations ranged widely (nd-35,544 and nd-16,344 ng kg −1 , respectively). Antibiotics and estrogens varied spatially in the study area and mostly came from untreated wastewater. Antibiotics and estrogens were associated with water parameters such as pH and total nitrogen. A significant positive correlation was observed between estriol and levofloxacin concentrations (r = .65; p < .01), indicating that levofloxacin from the same source might have inhibited the microbiological degradation of estriol in the surface water. Overall, the estrogens pose a more severe risk than antibiotics to the Chaohu Lake system. However, co-occurrence of antibiotics may affect the fate of estrogens in the same lake media. More attention should be given to estrogens than to antibiotics in wastewater-affected lake systems.

“…In aquatic organisms they can cause infertility and anomalies in reproductive organs and promote a significant decrease in sperm and their feminization in males [4]. In terrestrial environments, the use of manure as a fertilizer in agriculture has been identified as one of the top contributors to environmental pollution by estrogens, contaminating springs, rivers, and marine environments, among many other ecosystems that have contact with hormones [5].…”

Estrone (E1) is associated with various health and environmental issues, necessitating the development of analytical methods for monitoring E1 in different matrices. In this context, the present study reports the development of a graphene quantum dot‐based electrode (GQD/E) to detect estrone in water and urine samples. Voltammetric measurements under optimized conditions demonstrated the feasibility of using GQD/E to detect estrone at trace levels in aqueous samples. Two linear dynamic ranges were obtained at concentrations from 0.05 to 10.00 μmol L−1, with limit of detection (LOD) and quantification (LOQ) of 28.0 and 96.0 nmol L−1, respectively. Furthermore, the LOD value obtained in this study is one of the lowest ever reported in the literature for the electrochemical determination of E1. The method response showed no significant variation in the current intensity of E1 in the presence of the 16 interferents. The recovery values obtained by using GQD/E to quantify estrone in fortified samples of seawater, tap water, wastewater and synthetic urine ranged from 95.9 to 108.1 %, indicating that the method presents highly sensitive for detecting estrone in aqueous matrices.
