dear editor,<br />In the following sentence you edited before, the reviewer critized it as "The fact is not a study. English needs to be improved."<br /><br />Can you please let me know how the sentence should be rewritten in this case?<br /><br />your edited sentence was <br /><br />"Original: However, the fact that NPs directly extracted from our daily products behave similarly to industrial (commercially available) types is the first study and warrants further investigation, especially concerning the factors affecting their fate, toxicity, and mobility under heterogeneous aquatic systems."<br /><br />the reviewer does think the fact is not a study... so how should we rephrase the sentence?<br /><br />any suggestion?<br /><br />thanks in advance...
