Dear authors,

Thank you for your revision. I sent it to one of the original reviewers, who feels that you have addressed their comments, but that the additions to the manuscript contain some errors. They have listed the following points for checking and correction:

Page 3 line 14 “km” instead of “Km”
Page 3 line 28 Frioul and Lampedusa coordinates are wrong. Please check all the sites coordinates.
Page 3 line 29 please change “Lampedusa Islands” in “Lampedusa Islands”. Please check grammar and spelling in the whole manuscript. Es Page 11 line 9. Please change “Very few” in “few” or “scarce number”.
Page 3 line 31 Capital letter after coma. A reference is necessary here.
Page 4 line 2 please check the years of publications.
Line 15 pag 9. I think the sentence “And anthropogenic Zn….Guie et al. 2010.” has to be removed or rephrased.

Could you please check the above points, plus the other edits which were made, to make sure they are correct and that other errors did not make their way in during the revision process? I forsee that after these and any others are corrected, the manuscript can shortly be accepted.

Best wishes,

Andrew
