“…Its mean of 50.70 ng/L corresponds with the mean of 48.40 ng/L found in waters affected by urban and rural activities in China (Xu et al, 2014). The same authors report the SMX mean of 16.10 ng/g for corresponding sediment, while our sediment values (sites 4, 5, 9) decreased with the distance from the WWTP (19.60>5.07>0.99 ng/g).…”

Relating the treated wastewater quality and its impact on organismic biosensors (Prussian carp, Carassius gibelio and earthworm, Eisenia fetida) was the main objective of the study. The impact on health status of fish living downstream, microbiological contamination and antimicrobial resistance, fish tissue structure, blood biochemistry, oxidative stress, genotoxic effects, as well as multixenobiotic resistance mechanism (MXR) was assessed. Treated wastewater discharged from the WWTP modified the environmental parameters and xenobiotic concentrations of the receiving surface waters. Potential bacterial pathogens from fish and respective waters were found in relatively low numbers, although they comprised aeromonads with a zoonotic potential. High resistance profiles were determined towards the tested antimicrobial compounds, mostly sulfamethoxazole and erytrhomycin. Histopathology primarily revealed gill lamellar fusion and reduction of interlamellar spaces of effluent fish. A significant increase in plasma values of urea, total proteins, albumins and triglycerides and a significant decrease in the activity of plasma superoxide dismutase were noted in carp from the effluent-receiving canal. Micronucleus test did not reveal significant differences between the examined groups, but a higher frequency of erythrocyte nuclear abnormalities was found in fish sampled from the effluent-receiving canal. Earthworms indicated to the presence of MXR inhibitors in water and sludge samples, thus proving as a sensitive sentinel organism for environmental pollutants. The integrative approach of this study could serve as a guiding principle in conducting evaluations of the aquatic habitat health in complex bio-monitoring studies.Response to Reviewers: The response is attached as a separate file. We request that this manuscript be considered for publication in Science of the Total Environment as an original, full paper. This manuscript has not been published and is not under consideration for publication in any other journal. All authors concur with the submission.The manuscript is a result of a comprehensive study which integrated various disciplines and research fields. The authors decided to present it as a whole rather than splitting it in two or more papers, for a better understanding of the discussed subject. We believe we have presented a potential guiding principle for conducting evaluations of the aquatic habitat health in complex bio-monitoring studies.I will be serving as the corresponding author for the manuscript. We hope that it is found to be interesting and appropriate for publication in Science of the Total Environment. Should you have any questions, please do not hesitate to contact me.Yours truly, Natalija Topic Popovic, DVM, PhD Response: Thank you for this clarification. We have taken a whole different approach and completely rewritten all sections relating to the PCA as they were indeed confusing, and created a new biplot for plasma parameters. We hope that the new text, as inserted in the respect...

“…Probably, the reason for this is that total organic matter and cation exchange capacity in the sediment exert a greater affinity with the OTC, but the SMM may have relatively higher water solubility and weaker affinity to the sediments [51,52]. Furthermore, the mean concentration of OTC (44.6 ± 27.4 µg/kg) in the sediments was obviously higher than that in the Liao River (29.1 µg/kg) [49], Huangpu River (6.9 µg/kg) [48], and Yellow River Delta (4.9 µg/kg) [53], but comparable to that in the Taihu Lake [54]. However, it was dramatically lower than that in the Wangyang River (36,148.3 µg/kg) [35] and southern Baltic Sea [55].…”

Antibiotic pollutions in the aquatic environment have attracted widespread attention due to their ubiquitous distribution and antibacterial properties. The occurrence, distribution, and ecological risk assessment of 17 common antibiotics in this study were preformed in a vital drinking water source represented as a river-reservoir system in South China. In general, 15 antibiotics were detected at least once in the watershed, with the total concentrations of antibiotics in the water samples ranging from 193.6 to 863.3 ng/L and 115.1 to 278.2 µg/kg in the sediment samples. For the water samples, higher rain runoff may contribute to the levels of total concentration in the river system, while perennial anthropic activity associated with the usage pattern of antibiotics may be an important factor determining similar sources and release mechanisms of antibiotics in the riparian environment. Meanwhile, the reservoir system could act as a stable reactor to influence the level and composition of antibiotics exported from the river system. For the sediment samples, hydrological factor in the reservoir may influence the antibiotic distributions along with seasonal variation. Ecological risk assessment revealed that tetracycline and ciprofloxacin could pose high risks in the aquatic environment. Taken together, further investigations should be performed to elaborate the environmental behaviors of antibiotics in the river-reservoir system, especially in drinking water sources.

“…As a typical large shallow lake, Lake Tai has a maximum water depth of 2.6 m, but a mean water depth of just 1.9 m. The historical data for the period [1997][1998][1999][2000][2001][2002][2003][2004][2005][2006] reveal that the lake had a hydraulic retention time of 109-235 days [30]. Lake Tai has important ecological functions [31] and is the drinking water source for several major cities, including Wuxi (>1.5 million residents) and Suzhou (>1.4 million residents) in Jiangsu Province. However, over the past few decades, a large amount of wastewater with high concentrations of nutrients from local industries, domestics and agricultural sectors has been discharged into the lake, rendering the lake eutrophic with several severe cyanobacterial blooms [32,33].…”

Spatiotemporal Distribution of Eutrophication in Lake Tai as Affected by Wind

Abstract:One common hypothesis is that wind can affect concentrations of nutrients (i.e., nitrogen and phosphorus) and chlorophyll-a (Chl-a) in shallow lakes. However, the tests of this hypothesis have yet to be conclusive in existing literature. The objective of this study was to use long-term data to examine how wind direction and wind speed affect the spatiotemporal variations of total nitrogen (TN), total phosphorus (TP) and Chl-a in Lake Tai, a typical shallow lake located in east China. The results indicated that the concentrations of nutrients and Chl-a tended to decrease from the northwest to the southeast of Lake Tai, with the highest concentrations in the two leeward bays (namely Meiliang Bay and Zhushan Bay) in the northwestern part of the lake. In addition to possible artificial reasons (e.g., wastewater discharge), the prevalent southeastward winds in warm seasons (i.e., spring and summer) and northwestward winds in cool seasons (i.e., fall and winter) might be the major natural factor for such a northwest-southeast decreasing spatial pattern. For the lake as a whole, the concentrations of TN, TP and Chl-a were highest for a wind speed between 2.1 and 3.2 m·s −1 , which can be attributed to the idea that the wind-induced drifting and mixing effects might be dominant in the bays while the wind-induced drifting and resuspension effects could be more important in the other parts of the lake. Given that the water depth of the bays was relatively larger than that of the other parts, the drifting and mixing effects were likely dominant in the bays, as indicated by the negative relationships between the ratios of wind speed to lake depth, which can be a surrogate for the vertical distribution of wind-induced shear stress and the TN, TP and Chl-a concentration. Moreover, the decreasing temporal trend of wind speed in combination with the ongoing anthropogenic activities will likely increase the challenge for dealing with the eutrophication problem of Lake Tai.
