Reviewer 2 Report
Introduction
The introduction is very interesting, but the description of global problems, including international standards, can be more concise and present more recent investigations concerning phytoremediation. This point must be discussed more.
Materials and Methods
Fig 1 shows the sampling sites, but they are located in two regions. Are there representatives of the mining area?
Results and conclusions
Well explained according to the methodology used.
Author Response
Thank you for your comments.
In particular, we have summarized the introduction and considered more recent investigations concerning phytoremediation.
Regarding Fig 1, we have considered two sampling sites (S6P1 and S6P2) outside the mine to test if they are representative of the mining area. The results haighlight that S6P2 has the same characteristics of S4P1 and S4P2 (Class A); S6P1 has the same characteristics of S3P1, S2P1, S1P1 (Class C). So, they are representative of the mining area.
Reviewer 3 Report
The article concerns the use of the mycorrhiza-assisted phytoremediation method to remove metals from mineral waste. The use of biological methods to improve the quality of the environment, degraded as a result of anthropopressure, should be treated as a priority. The topic taken up is very topical due to the current trends in waste management in the context of the circular economy. The authors conducted a very comprehensive and interdisciplinary study, the pattern of which can be replicated in other industrially degraded regions.
