Suggestions for revision or reasons for rejection

Reviews: The revised manuscript has addressed most of the concerns and questions from previous reviewers except for the writing part. The scientific writing (grammar, choice of wording, etc.) needs to be greatly improved. Some of the sections, e.g.QA/QC and discussion is a little weak.
Specific comments on the manuscript
1. Title, what do you mean by seasonal of OP esters? Maybe better change the title to “Seasonal distributions and ….”?
2. Abstract, line 14, significant numbers for the measured concentrations should be consistent.
3. Abstract, line 18, “high levels” instead of “high level”.
4. Abstract, line 19, delete “Very”.
5. Abstract, line 25-27, please check grammar and the selection of wording. E.g. line 25, maybe use “from the inland city” instead of “in the inland city”. Line 26, delete “the”. Line 27, change “whose”.
6. Intro, line 41, rephrase line 41.
7. Intro, line 44, change “appeared”.
8. Intro, line 47-line 49, those three sentences should be linked with some connection words, at least not by commas.
9. Intro, line 51, change “especially” to “mainly”.
10. Intro, line 51-52, change “little attention was paid to.”
11. Intro, line 53, you may delete “typical”.
12. Intro, line 56, “the important” change to “an important”.
13. Intro, line 64, “profiles”?
14. Materials and Methods. Chemicals. Line 72-79, rewrite this paragraph.
15. Materials and Methods. Sample Collection, line 92-94, please rephrase to be more concise. And what do you mean by “weather conditions could represent typical weather conditions of the season”?
16. Materials and Methods. QA/QC, delete line 117.
17. Materials and Methods. QA/QC, line 118, recovery efficiency? Recovery=extraction efficiency. “Add” might be better changed to “Spiked”.
18. Results and Discussion, line 137, change “in the air of Chengdu city”.
19. Results and Discussion, line 151-161, did those studies you cited serve as support for the sentence in line 145-147? Could you provide more discussion instead of listing the literature values?
20. Results and Discussion, line 190, please rephrase.

Short summary

Samples were collected from six ground-based sites located in Chengdu, a typical rapidly developing metropolitan area in Southwest China, and were analysed for seven OPEs in atmospheric PM_2.5 (Σ₇ OPEs). The concentrations of Σ₇ OPEs were higher in autumn and winter than in summer. In contrast to coastal cities, sustained and stable high local emissions in the inland city studied were identified, which is particularly noteworthy.
