“…Numerous researchers have been monitoring the fate of estrogens in Waste Water Treatment Plants (WWTPs) and assessing the efficiency of different treatment processes in removing SEs [8,9]. The degradation, sorption, and mobility of SEs have been areas of concern, with their potential risks to surrounding surface water and groundwater being widely acknowledged [10][11][12]. For animal manure, composting is the most commonly adopted method of bioresource utilization.…”

Steroid estrogens (SEs) play a significant role as endocrine-disrupting substances, and one of their major sources is animal manure. However, there is limited information available regarding the loss of SEs in farmland soil after the application of commercial composted animal manure or fertilizers. To address this gap, our study aimed to simulate rainfall and flood irrigation scenarios and investigate the loss characteristics of SEs, as well as Chemical Oxygen Demand (COD), Total Nitrogen (TN), and Total Phosphorus (TP) in runoff from soil–manure mixtures. The results demonstrated that the loss concentrations of SEs (73.1 ng/L of the mean E2β active equivalent factor) presented a potential environmental risk. Additionally, substituting composted manure with commercial organic fertilizers lead to a significant reduction in TP (maximum 56%) and TN (maximum 24%) loss. Consequently, the application of commercial organic fertilizers offers considerable advantages in maintaining nitrogen and phosphorus fertilization efficiency while controlling SEs loss. Furthermore, our study explored the synergistic pollution mechanism among these pollutants and observed significant correlations between SEs and TN, TP, and COD loss concentrations, indicating the simultaneous occurrence and migration of these pollutants in agricultural non-point source pollution. These results provide valuable insights into the environmental risk associated with SEs from agricultural non-point sources.

“…However, studies evaluating EC removal during AC of AD digestate were lacking, and results of studies focused on AC may not be relevant to a combined AD/AC system due to changing redox conditions likely affecting EC‐degrading microorganisms. Optimal populations of EC‐degrading microorganisms are critical, and microbial community composition and composting conditions are linked with EC half‐lives (Abdellah et al., 2020; J. N. Zhang et al., 2019). Further, few studies have rigorously examined the impact of operational conditions (e.g., pH, temperature, and digestate carbon source composition, which change through the composting phases) on EC degradation and EC‐degrading microbes (Lin et al., 2017) making process optimization difficult.…”

Sustainable manure management technologies are needed, and combining anaerobic digestion (AD) for energy generation and aerobic composting (AC) to stabilize digestate and remove emerging contaminants (ECs), including veterinary pharmaceuticals and steroid hormones, is promising. This study identified post AD, AC operating conditions that maximized degradation of study ECs, expected to be present in cattle manure digested using treated municipal wastewater as the water source. Study ECs included sulfamethoxazole (SMX), chlortetracycline (CTC), oxytetracycline (OTC), estrone (E1), and naproxen (NPX). Composting conditions were simulated in bench‐scale reactors, with microorganisms from digestate produced in an AD system (25L scale), by varying temperatures, pH, and carbon source compositions (representing food waste/manure co‐digestion with different residence times). Results indicate maximum SMX biodegradation happened at 35°C, pH 7, and with high levels of easily degradable carbon (≥99, 99, 98%), and maximum E1 biodegradation occurred at 35°C, and with low levels of easily degradable carbon (≥97, 99%). Abiotic degradation was responsible for nearly complete removal of tetracyclines under all conditions and for partial degradation of NPX (between 20–48%). Microorganisms originating from the AD system putatively capable of SMX and E1 biodegradation, or of contributing to biodegradation during the AC phase, were identified, including phylotypes previously shown to biodegrade SMX (Brevundimonas and Alcaligenes).This article is protected by copyright.

“…Removal of estrogen from the aquatic environment is important, however, it is difficult to achieve even with the use of modern filtration methods [6][7][8]. As evidenced by recent research, microbial degradation of estrogens can be led by many bacteria strains i.e., Rhodococcus, Novosphingobium, Acinetobacter, Agromyces, and Sphingomonas, thus showing possible safe and inexpensive ways for the reduction of threat involved with such pollution [9][10][11][12][13]. It is worth noting that some fungi, mainly species belonging to Aspergillus genus are also reported to perform aerobic degradation of estrogens [9].…”

Nowadays, there is a growing interest in environmental pollution; however, knowledge about this aspect is growing at an insufficient pace. There are many potential sources of environmental contamination, including sex hormones—especially estrogens. The analyzed literature shows that estrone (E1), estradiol (E2), estriol (E3), and synthetic ethinyloestradiol (EE2) are the most significant in terms of environmental impact. Potential sources of contamination are, among others, livestock farms, slaughterhouses, and large urban agglomerations. Estrogens occurring in the environment can negatively affect the organisms, such as animals, through phenomena such as feminization, dysregulation of natural processes related to reproduction, lowering the physiological condition of the organisms, disturbances in the regulation of both proapoptotic and anti-apoptotic processes, and even the occurrence of neoplastic processes thus drastically decreasing animal welfare. Unfortunately, the amount of research conducted on the negative consequences of their impact on animal organisms is many times smaller than that of humans, despite the great richness and diversity of the fauna. Therefore, there is a need for further research to help fill the gaps in our knowledge.
