Round 1

Reviewer 1 Report

This manuscript reviews the Toxic and Trace Elements in Seaweeds from a North Atlantic  Ocean region (Tenerife, Canary Islands) . This article is an interesting article that would be well suited for readers of the Journal. It may be considered for publication after major revisions.

  1. In the present study, there is not sufficient novelty and this should be highlighted in the manuscript.
  2. The standard deviation of Fe and Al are ±1,545 and ±157 (Line 20 and 21 in Abstract section). The authors should explain why standard deviations are so high in these data.
  3. It is essential that authors demonstrate their originality by fully justifying their work. In order to accomplish this, it should be compared with previously published materials that serve the same purpose. Authors should elaborate on the significance of their work.
  4. The abstract should be rewritten. It is important to emphasize quantitatively the main results.
  5. Describe in one to three sentences the significance of the work in the introduction.
  6. Algae are the best bioindicators of marine pollution, and they may be used for bioremediation in contaminated environments (Line 56). Add more details in this paragraph about it and water pollution. This can be improved by suggesting relevant references. Fuel. 311, 122543; J. Environ. Chem. Eng. 9, 106160; Environ.

Response: Part of this research was presented before in the 3rd International Electronic Conference on Environmental Research and Public Health —Public Health Issues in the Context of the COVID-19 Pandemic. However, it was not as a conference paper, it was as a poster. Therefore, publishing now as a paper allow the authors show their results, methodology and other information in detail.

Reviewer 2 Report

I would like to thank the authors for their response. TI thinks that the paper is accepted and ready for publication. One more thing, I encourage authors to revise the scientific names one more time. I observed that some scientific names are not italic and the "spp" is a regular, not italic. Please, check it for last time.

Best Regards
