A falta de medidas de proteção ambiental no sepultamento de corpos em áreas apropriadas, fez com que muitos cemitérios fossem instalados em áreas inadequadas acarretando na contaminação do solo e dos recursos hídricos. Os poluentes inorgânicos mais tóxicos que ocorrem em solos estão sob a designação de “metais pesados”. Nesse contexto, o presente estudo tem por objetivo determinar alterações nas propriedades químicas em solo ocupado por cemitério na cidade de Seberi - RS. Para a realização do estudo foram realizadas tradagens no solo nas profundidades de 0 a 300 cm. Para a determinação dos metais foi utilizada a técnica de Espectrômetria de Fluorescência de Raios-X – EDXRF. Os valores de Al variaram de 78672 a 185479 mg kg-1, as concentrações de Ca e Fe variaram de 256 a 38368 mg kg-1 e 54815 a 205796 mg kg-1, respectivamente. Observou-se que os valores dos elementos Al e Ca apresentaram os maiores valores nas menores cotas topográficas nas profundidades até 150 cm, diferentemente do elemento Fe que apresentou o maior valor no ponto P5. Com isso é possível concluir que a área apresenta alterações em função da presença do cemitério.

Ethical Guidelines for Journal Publication
The Ciência e Natura journal is committed to ensuring ethics in publication and quality of articles.
Conformance to standards of ethical behavior is therefore expected of all parties involved: Authors, Editors, Reviewers, and the Publisher.
In particular,
Authors: Authors should present an objective discussion of the significance of research work as well as sufficient detail and references to permit others to replicate the experiments. Fraudulent or knowingly inaccurate statements constitute unethical behavior and are unacceptable. Review Articles should also be objective, comprehensive, and accurate accounts of the state of the art. The Authors should ensure that their work is entirely original works, and if the work and/or words of others have been used, this has been appropriately acknowledged. Plagiarism in all its forms constitutes unethical publishing behavior and is unacceptable. Submitting the same manuscript to more than one journal concurrently constitutes unethical publishing behavior and is unacceptable. Authors should not submit articles describing essentially the same research to more than one journal. The corresponding Author should ensure that there is a full consensus of all Co-authors in approving the final version of the paper and its submission for publication.
Editors: Editors should evaluate manuscripts exclusively on the basis of their academic merit. An Editor must not use unpublished information in the editor's own research without the express written consent of the Author. Editors should take reasonable responsive measures when ethical complaints have been presented concerning a submitted manuscript or published paper.
Reviewers: Any manuscripts received for review must be treated as confidential documents. Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Reviewers should be conducted objectively, and observations should be formulated clearly with supporting arguments, so that Authors can use them for improving the paper. Any selected Reviewer who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the Editor and excuse himself from the review process. Reviewers should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the papers.
