Analysis of the Spatial Distribution Characteristics of Emerging Pollutants in China
Round 1
Reviewer 1 Report
This article is a comprehensive article with good English proficiency. However, the research content is relatively flat and does not highlight the significance of the study. Perhaps the significance is not very obvious. The suggestions and opinions proposed at the end of the article are also the conclusions of existing papers, without the author's own constructive opinions. The analysis of existing data is too simplistic. Without conducting this study, most conclusions can be drawn. Of course, the writing of the article is still good. It is recommended that if the author can supplement a large amount of data analysis and their innovative viewpoints, I can re-examine whether to publish it.
English is good.

Reviewer 2 Report
This paper focuses on the analysis of the spatial distribution characteristics of emerging pollutants in China which is a very interesting topic. In recent years, the emerging pollutant pollution has increasingly attracted more attention. It is essential to conduct more studies on emerging pollutants. This paper is well written, some specific comments are as follows:
1. Please provide a brief list of the toxic effect of emerging pollutants in further detail.
2. Please shorten the description of traditional pollutants. The abbreviation for heavy metals in the first paragraph should appear the first time the word is used.
3. Please appropriately add a discussion of how to remediate emerging pollutants in the introduction section, you may refer to 10.1007/s42773-022-00201-x, 10.3390/ijerph20031679
4. The authors have extracted many data and plotted different graphs, however there is a lack of detailed discussion for each pollutant. Only the concentration of pollutants and their distribution can be seen from the graphs. Please add a corresponding discussion in each section, e.g. why are there high concentrations of emerging pollutant in some areas? Is this related to local industries or to hydrological differences in different areas? The authors do not discuss this in the text.
5. Please add a discussion of the significance of this study in the conclusion section, as well as adding a discussion of future research directions.
English needs minor revision.

Reviewer 3 Report
Dear editor,
Thanks for inviting me to review this manuscript titled “Analysis of the spatial distribution characteristics of emerging pollutants in China”. In this manuscript, the authors reviewed the existing quantitative research results of four common emerging pollutants in water environment in China. Also, extracted the quantitative monitoring results of the emerging pollutants in the case studies, and outlined the spatial distribution characteristics of the emerging pollutants in the water environment. This manuscript was interesting and, thus, I recommend this manuscript be considered for publication after some revisions.
--It is recommended that more background information on emerging pollutants be provided, listing some typical representative substances and what the specific hazards are.
--The results section of Section IV was suggested to a further explanation.
--It is recommended that further details of survey sampling methods or experimental testing methods and data sources be added to improve the persuasiveness of the article.
--The strengths and weaknesses of the existing monitoring systems for water quality indicators was suggested
--The pollutant concentrations in Figures 2, 3, 4 and 5 should be represented by different color circles to make their expression more clearly.
--It is recommended that the pollutant concentrations in Figures 2, 3, 4, and 5 be supported by accurate data, and the data are interpreted through relevant comparisons to improve the persuasiveness of the article.
English languag is basically qualified and does not require major modifications

Reviewer 4 Report
Introduction: L40-41, make space between the name of chemicals and their abbreviations
L54-73: The reviewer misses mentioning some practical tools for monitoring these pollutants, such as regular field methods, usage of bioindicators in the field and laboratory, etc. I recommend to check and mention some articles in this part like https://www.sciencedirect.com/science/article/pii/S2405844022003577?via%3Dihub
https://www.sciencedirect.com/science/article/pii/S1532045622001818?via%3Dihub
Material & methods: Make space between L11 and Table 1
Revise Table 1, in this case, the information and rows are hardly can be separated
Make space between 1) and the sentence in L118
Results
Figure 2-5: In the case of every table and figure, the title has to be understandable in itself, and it has to avoid using abbreviations that are defined somewhere in the text.

Reviewer 1 Report
Although I have different opinions on the meaning of the article, the writing is still very good. If other reviewers and editors believe it can be published. I have no different opinions.
