Abstract Endocrine-disrupting compounds (EDCs), represented by steroidal estrogens (estrone (E1), 17β-estradiol (E2), estradiol (E3), and 17α-ethinylestradiol (EE2) and xenoestrogens (bisphenol A (BPA) and nonylphenol (NP)), are pollutants with estrogenic activity at very low concentrations and are emerging as a major concern for water quality. They enter into aqueous environment mainly through discharge of wastewater treatment plant (WWTP) effluents. The paper completely reviews recent studies… 
Biodegradation and Metabolic Pathway of 17β-Estradiol by Rhodococcus sp. ED55
The acute test with luminescent marine bacterium Aliivibrio fischeri revealed the elimination of the toxicity of the treated effluent and the standardized yeast estrogenic (S-YES) assay with the recombinant strain of Saccharomyces cerevisiae revealed a decrease in the estrogenic activity of wastewater samples after biodegradation.
Removal of Six Estrogenic Endocrine-Disrupting Compounds (EDCs) from Municipal Wastewater Using Aluminum Electrocoagulation
Conventional wastewater treatment plant (WWTP) processes are primarily designed to reduce the amount of organic matter, pathogens, and nutrients from the incoming influent. However, these processes
The Presence of 17 Beta-Estradiol in the Environment: Health Effects and Increasing Environmental Concerns
The aim of the present study was to review and evaluate the endocrine disrupting compounds especially 17 beta-estradiol, as a representative of estrogen hormones present in the environment and their disturbing effects on humans and wildlife.
Occurrence and distribution of six selected endocrine disrupting compounds in surface- and groundwaters of the Romagna area (North Italy)
Overall, the northern part of the Romagna area showed a higher contamination by EDCs, in contrast with the southern part, which was almost unaffected by this kind of microcontamination.
Occurrence, sorption, and transformation of free and conjugated natural steroid estrogens in the environment
The properties, occurrence, sorption process, and transformation pathways of NSEs are clarified in the environment and the elimination of total estrogenic activity needs to be addressed in further studies.
Biotransformation strategies for steroid estrogen and androgen pollution
The present review is focused on the major causes of steroid pollution, concentrations of these pollutants in surface water, groundwater, drinking water, and wastewater, their effect on humans and aquatic animals, as well as recent efforts by various research groups that seek better ways to degrade steroids by aerobic and anaerobic microbial systems.


Occurrence of estrogenic endocrine disrupting chemicals concern in sewage plant effluent
The purpose of this study was to give a worldwide overview of the concentrations of typical estrogenic endocrine disrupting chemicals (EDCs) in the effluent of sewage plants and then compare the
Occurrence, fate, and biodegradation of estrogens in sewage and manure
The purpose of this review is to highlight the significance for both health and the environment of pollution by estrogens and critically review the existing knowledge on their fate and removal in different treatment processes.
Processes for the elimination of estrogenic steroid hormones from water: a review.
Occurrence and fate of hormone steroids in the environment.
Endocrine-disrupting chemicals in the Pearl River Delta and coastal environment: sources, transfer, and implications
The results of this study point to the potential that Pearl River is a significant source of the endocrine-disrupting chemicals to the local environment there.
Occurrence of estrogenic chemicals in South Korean surface waters and municipal wastewaters.
The levels of E1, E2, and EE2 were remarkably decreased in the effluents, indicating that the 5 WWTPs did not contribute to the estrogenic effect of the receiving streams, but the livestock industry or wildlife may play an important role in the estrogenIC contribution to river water.
