Distribution of Selenium in the Soil–Plant–Groundwater System: Factors Controlling Its Bio-Accumulation
Round 1
Reviewer 1 Report
Line 51: I suggest to add some more recent studies in similar issues, Vasileiou et. al 2019 (Sarigkiol basin), Dermatas et.al 2014 (Vergina), Remountaki et.al 2016 (Psachna)
Line 90: average values? from both wet and dry seasons? Maybe you have to be more precise
Line 104: delete Se
Line 114: not A, replace with Al
Line 137: id shoots? maybe in shoots
Line 145 and 149: you have to correct these two sentences
You have to decide in the tables how many decimals digits you will put, to be the same in all tables.
Line 170: delete Se, after 88 μg/l
Line 185: coastal
Line 188:not costal replace with coastal
Line 263: references missing concerning fly ash and the leachate in groundwater....Vasileiou et al.2019, Tsioptsias et.al 2020, Dermatas et.al 2012
It is necessary to add a paragraph concerning the groundwater quality, remarks about some concentrations e.g. Cr, Na, Mg. If you have analyses for Cl- or NO3- in groundwater, I suggest to add them to the relative table. There is a discussion about a coastal aquifer without concentrations of major ions concerning seawater intrusion.
There is not a clear connection for Se, between soil-groundwater-plants , it is a little confused

Reply: The suggested references are included now:
Line 90: average values? from both wet and dry seasons? Maybe you have to be more precise
Reply: It was clarified now.

Reply: Analyses for Cl or NO33- are not available to include them. Differences between contaminated coastal groundwater and drinking/sea water are now discussed.
There is not a clear connection for Se, between soil-groundwater-plants , it is a little confused
Reply: Parts of the sections 3.2, 3.3, 4.1 and 4.2 were re-written, hoping that the relationships between Se in plants and soil are clearer now.
Thank you very much for your helpful comments for improving the quality of our MS.
