“…Moreover, both TEE2 and TE1 have become the most sensitive endocrine disruptors among adolescents, resulting in a serious impact on the health of young people. 8 The estrogenic efficacy of TE2, TEE2, and TE1 is more than 3 orders of magnitude higher than that of most endocrine disruptors, such as nonylphenol and bisphenol A. 9 Consequently, the detection of total steroid estrogens (TEs) is highly desired due to the synergetic effects of such compounds on the environment.…”

Steroid estrogens, including 17β-estradiol (TE2), estrone (TE1), and ethinyl estradiol (TEE2), which are the strongest endocrine disruptors and coexist in the environment, seriously harm the health of organisms; thus, the monitoring of total steroid estrogens (TEs) has attracted growing attention. Herein, a method based on surfaceenhanced Raman spectroscopy (SERS) group-targeting detection is established to detect TEs in natural water for the first time. The TEs response detection range and detection limit were 0.01−50 nM and 5 pM, respectively. An antiinterference ability was observed: even if coexisting interfering species were present in the system at 100-fold the concentration of estrogens, the detection error of the method was less than 0.276. In addition, the association constants between the aptamers and TE1, TE2, and TEE2 were similar, and therefore, the recognition of TE1, TE2, and TEE2 by the aptamers was consistent. Furthermore, the interaction sites A44, T72, and G69 between the aptamers and TE1, TE2, and TEE2 were investigated by molecular docking. On this basis, the estrogens in environmental water samples, including animal farm wastewater, maternity hospital wastewater, surface water from near an animal farm, and surface water from near a maternity hospital, were successfully determined. E strogens, a kind of environmental endocrine disruptor, are

To explore the existing characteristics of nitrogen and phosphorus in the main rivers of Changchun City, the overlying water and sediment were sampled and tested. The results showed that the spatial distribution of nitrogen and phosphorus contents in overlying water and sediment was diverse. In overlying water, nitrogen and phosphorus contents in the north and west of Changchun were high, while their contents in the south were low. In the sediment, their contents were high in the south and west and low in the north. The pollution of nitrogen and phosphorus was serious in most rivers. Xinkai River, Chuan Lake, and West Lake had the acutest pollution of ammonia, total nitrogen, and total phosphorus, and their contamination degree in Yongchun River was the lowest. In terms of time, with the government actively carrying out river management, the pollution control of ammonia and phosphorus has achieved remarkable results. The pollution of nitrogen and phosphorus was closely related to the quality of the water environment, and the phosphorus content in overlying water and sediment had the strongest correlation with other water quality parameters. Moreover, the change in chemical oxygen demand could be predicted by the partial least squares method on the basis of its high correlation with nitrogen and phosphorus in overlying water. This study provides a scientific reference for the investigation and treatment of nitrogen and phosphorus pollution in surface water of typical old industrial cities in China.
