Dear Rebecca,<br />I have the following questions and would appreciate if you can quickly check and answer to the questions due to the due date I must submit soon.<br /><br />Q1. In your comment, RM4: In the ms. that I'm looking at, something is wrong here - the figure blocks out part of the final sentence under "Innovation"<br /><br />The following is what was written and so can you please check if there are any errors on the following sentence?<br /><br />--&gt; "This study will provide new information and critical data essential for assessing environmental and human health toxicity".<br /><br />Q2. Also, in the figure 1 (since there are no comments, I wonder what I wrote is ok and need to check with you), <br /><br />Fig. 1 Effect of existing contaminant (siloxane) on deposition and transport behavior of ZnO NPs in porous media,<br /><br />Here do you see any errors on the above subtitile of Fig. 1?<br /><br />Also I'm still confused if I should write "Effect" or "Effects"<br /><br />please check all the questions I have and let me know.<br /><br />thanks in advance,<br /><br />p.s. I expect to send you 15 pages document sometime next week and 30 pages in the following next week, and subsequently more documents in October... hope your schedule is fine with the rest of Sept. and October...<br /><br />
