dear editor,<br /><br />I have one last question. In the following sentence, you revised it as follows.<br />"As an example, cadmium was found to adsorb strongly onto nano-TiO<sub><span style="font-size: small;">2</span></sub> owing to the NPs&rsquo; physicochemical properties (small size, large surface area, and strong electrostatic attraction), and then being transported<strong> to places where</strong> they accumulate in marine organisms."<br /><br />Here, I meant to say "nanoparticles can be transported to every environmental media, not just one medium (for example, marine environment). But once NPs are transported, it could be accumulated in marine organisms"<br /><br />So based on what I meant to say, can you revise the above sentence?
