Round 1
Reviewer 1 Report
Introduction must be improved. Heavy metals' standard limits set by FAO/WHO must be given for each metals.
Materials and methods must be improved. If the plants used for analysis are cultivated, agricultural practices (chemical fertilization, irrigation, pesticides used etc.) and detailed soil analysisi for each region must be given in details.
Discussion part is poor. More literature must be given and discussed former scientific data.
