“…They can produce serious danger to humans due to bacterial resistance and with this, the suppression of immune response. Even at low concentrations (they are released from ng L -1 to mg L -1 ) they can cause adverse effects to aquatic organisms like endocrine disruption or growth affections, because their mode of action and their properties are not designed to treat these organisms [6] , [9] , [10] , [11] , [13] , [14] . Among all the pharmaceuticals detected in water sources, the presence of analgesics and anti-inflammatories, (paracetamol, ibuprofen, ketoprofen or dexamethasone), antibiotics (amoxicillin, azithromycin, or sulfamethoxazole) or psychiatric drugs (sertraline, clonazepam or fluoxetine) is worth highlighting [15] , [16] , [17] , [18] , [19] , [20] .…”

“…RQ site is the ecological risk from a river water sample. The RQ values were classi ed into four indicating different risk levels: negligible risk (RQ < 0.01), low risk (0.01 ≤ RQ < 0.1), medium risk (0.1 ≤ RQ < 1), and high risk (RQ > 1)(Figuière et al, 2022).2.8 Statistical analysisSpearman correlation analysis and Kruskal-Wallis test were performed with IBM SPSS Statistics 25.

N-nitrosamines are widespread in various bodies of water, which is of great concern due to their carcinogenic risks and harmful mutagenic effects. Livestock rearing, domestic, agricultural, and industrial wastewaters are the main sources of N-nitrosamines in environmental water. However, information on the amount of N-nitrosamines these different wastewaters contribute to environmental water is scarce. Here, we investigated eight N-nitrosamines and assessed their mass loadings in the Desheng River to quantify the contributions discharged from different anthropogenic activities. NDMA (8.5 ± 5.2 ng/L), NMEA (0.1 ± 0.4 ng/L), NDEA (1.2 ± 1.0 ng/L), NPYR (1.6 ± 4.1 ng/L), NMOR (7.0 ± 7.1 ng/L), NPIP (0.3 ± 0.7 ng/L), and NDBA (7.8 ± 3.8 ng/L) were detected. NDMA and NDBA were the dominant compounds contributing 89% and 92% to the total N-nitrosamine concentrations. The mean cumulative concentrations of Nnitrosamines in the livestock rearing area (26 ± 11 ng/L) and industrial area (24 ± 4.8 ng/L) were higher than those in the residential area (16 ± 6.3 ng/L) and farmland area (15 ± 5.1 ng/L). The signi cant negative correlation between NDEA and dissolved oxygen indicated the light-screening effect. The mean concentration of N-nitrosamines in the tributaries (22 ng/L) was slightly higher than that in the mainstem (17 ng/L), probably due to the dilution effect of the mainstem. However, the mass loading assessment suggested the negligible mass emission of N-nitrosamines into the mainstem from tributaries, which could be due to the small water ow of tributaries. The average mass loads of N-nitrosamines discharged into the mainstem were ranked as the livestock rearing area (742.7 g/d), industrial area (558.6 g/d), farmland area (93.9 g/d), and residential areas (83.2 g/d). In the livestock rearing, residential, and industrial area, NDMA (60.9%, 53.6%, and 46.7%) and NDBA (34.6%, 33.3%, and 44.9%) contributed the most mass loads; NDMA (23.4%), NDEA (15.8%), NPYR (10.1%), NPIP (12.8%), and NDBA (37.8%) contributed almost all the mass loads in the farmland area. Photodegradation amounts of NDMA (0.65 ~ 5.25 µg/(m 3 •day)), NDEA (0.37 ~ 0.91 µg/(m 3 •day)), and NDBA (-0.06 ~ 0.66 µg/(m 3 •day)) were also calculated according to the mass loading. Quantifying the contribution of different anthropogenic activities to the river will provide important information for regional river water quality protection.
