A Comparison of Ambient Air Ethylene Oxide Modeling Estimates from Facility Stack and Fugitive Emissions to Canister-Based Ambient Air Measurements in Salt Lake City
Round 1
Reviewer 1 Report
Spooner et al presented measurements and modeling of ethylenne oxide over Salt Lake City, Utah US. This study is valuable since present measurements of this flammable gas which is not typically monitored. However, , the manuscript presents aspects that MUST be corrected. This manuscript is short, appropiate for a communication and not a research article. Below my main concerns:
Paragraph between lines 81 and 91 is messy and not clear. Edit.
Lines 124-126. Why splitting the research in many papers? Is it to show more productivity for funding?
Line 140, delete :"Newly purchased"
Line 185, Add M capital to Multipliers
Line 205, Rstudio is an interface for R programming language. The correct citation is obtained by running `citation()` in R terminal, which in my case gives:
R Core Team (2022). R: A language and environment for statistical computing. R Foundation for Statistical Computing, Vienna, Austria. URL https://www.R-project.org/.
Figure 1. Add labels in points located in West Vallwy City and the other two at north.
I did not find any evidence of biogenic ethylene oxide. Provide basis or change.
Remove trables 2 nd 3 and present the data as figures or panels in the same figure 2. Wilcoxon is to detect existance of significant differences. Hence, only p.value< is needed, (not greater than).

Reviewer 2 Report
1. What is the significance of the placement of eight sampling points? Why are the measurement points arranged like this?
2. Figure 3 is not easy to understand. What do points and rectangles represent? as the only data graph in the paper, received very little analysis.
3. The discussion section has less content, so it is recommended to add some analysis.
4. μg/m3 should be "μg/m3".
5. The font size in the table should be consistent.
6 . The Figure 2 mentioned in the article is not found.
7. Table 1 is too vague, the style of Table 1, Table 2 and Table 3 in the paper needs to be unified, and the text size is different.
8. Lines 133-134, page 3: "the controlled and uncontrolled EtO emissions" How does that work here? Does it correspond to 144 lines of this page? The introduction is not clear enough, can be supplemented with pictures to explain.
9. Lines 154-157, page 4: "A temporalization analysis " If the effect of wind is greater, should it be taken into account?
10. Lines 186-190, where the formula is kind of out of place, right?
11. Lines 213, page 5: "Sites 6 and 8 showed no statistical difference " There is a clear difference in Site 6, and What does the Wilcoxon p-values mean?
12. Why is there no BG5 summer data in Table 3? Is it possible that the background value in summer is too high and caused this difference? This issue has yet to be resolved.
13. Lines 287, page 8: "two collection methods" Whether you want to express two ways of measuring EtO here?
