General recommendations

A review of a manuscript should be prepared within 30 days. A mansucript can be accepted, sent back for correction (with no subsequent review or with another review after major corrections) or rejected. The review is entered into the J. Elem. system after the Reviewer has answered the questions. It is also possible to submit a review in the form of a manuscript with the reviewer’s comments written in the text. Each review must be concluded with the reviewer’s opinion whether the manucript is acceptable or should be rejected (including the justification). By accepting a manuscript for review, a reviewer agrees to their affiliation (name, surname, town, country) being published on the website https://jsite.uwm.edu.pl//issue/reviewers and in the printed version of the Journal of Elementology.

 Rejection: an article has serious flaws (especially in methodology, statistics) or it does not contribute anything original to the development of science. Please, remember that the assessment of your article is only seen to the Journal’s Editors and the Author(s). The Author does not know the affiliation of the Reviewers. The Reviewers are anonymous.
