“…With recent advances in techniques and analytical instruments, it has been possible to detect levels and traces of various ECs in the environment, including surface water, groundwater, wastewater, drinking water, sediments, soil, and even in some organisms (Wang et al, 2017). The presence of these compounds in aquatic matrices is a serious threat to the environment and humans (Shanmuganathan et al, 2023).…”

This work aimed to analyze the presence of four common molecules (diclofenac, dipyrone, ibuprofen, and paracetamol) in the Ipojuca River, in the stretch of Caruaru municipality (Brazil), and in a wastewater treatment plant that discharges treated water to the river. Collections were conducted for three months at each point during April, May, and June. The samples were collected in three repetitions (sample, replica, and triplicate). Through Pearson’s correlation, the correlation between ibuprofen and diclofenac concentration and rainfall in the region was also verified. These drugs were detected in 100% of the samples, with concentrations between 7.4–548.2 and 81.8–231.8 μg.L-1, respectively. Paracetamol and dipyrone were not detected. The observed high concentrations are due to the high consumption of drugs and the low rate of sewage collection in the municipality. Both analyzed drugs — ibuprofen and diclofenac — had insignificant correlation results with rainfall (-0.022 and -0.071, respectively). Regarding the drugs in the WWTP, the treatment consisting of anaerobic followed by aerated lagoons showed efficiency ranging from 35.9 to 93.6% in the removal of diclofenac. The removal of ibuprofen was higher in April (86.6%), but in the other two months, it did not prove to be efficient, evidencing the need to implement more adapted technologies in the removal of drugs combined with the network expansion for sewage collection in the region. A study with longer time monitoring is needed to understand the rainfall effect on drug concentration in the river.

“…The role of industry and agriculture is indisputable, but the contribution of discharges from common and combined wastewater treatment plants (WWTPs) is sometimes underestimated [14]. The implementation of innovative facilities and advanced technologies for the removal of emerging contaminants in industrial waste ows signi cantly reduces their release in the aquatic environment but conventional technologies are unlikely to eliminate them, especially at trace levels typically found in municipal wastewater [15,16,17]. Municipal wastewater e uents are complex mixtures treated to varied degrees but generally containing residual biodegradable organic substances, nutrients, and micropollutants whose effects on natural water bodies can often be masked by each other.…”

The contribution of urban sewage treatment plants to pollution with emerging contaminants is still underestimated and discharge zones are not always subject to adequate monitoring activities. In this study, we apply the combination of risk level ranking of a specific class of pollutants (potentially toxic elements) and assessment of the metabolic activity of sediment microbial communities. The ranking approach identifies the most harmful toxic elements in the local environment of the upper sub-catchment of the Iskar River, Bulgaria. The effect on microbial communities was assessed by the determination of the share of viable cells and the inhibition of their metabolic activity (fluorescent staining method with digital image analysis). The data showed that Hg and Cu came at the top of the list of concerns for the matrix of surface waters; Cu, Cd, and Pb pose the greatest risk in sediments. The microbial communities in the wastewater discharge area were affected by pollutants and by the high nutrients and organic content of the effluent. The applied approach has the potential to help us focus the future site-specific monitoring for pollution control in water bodies, receiving wastewater discharges, and contributes to a better understanding of the potential ecological risks from hazardous pollutants.
