necessary to plan and execute proper ways of checking heavy element contents in food crops grown in cropland settlements to avoid their undue accumulation in the feeding level. The potential health hazards of heavy elements utilizing other exposure pathways need to be in the interest of future research. The work has provided information on the extent of heavy element pollution in the cropland establishment as a way of assessing the environmental health of the area under study as a result of heavy element pollution. The work also added to the baseline data on risk of potentially toxic elements studies in our environment. A cknowledgements The authors are grateful to Directors and Workers of Odu’a Farm Settlement, Oyo State for permitting the use of their arable land as sampling site for this analysis. The Centre for Energy Research and Development (CERD) of the Obafemi Awolowo University, Ile-Ife, Nigeria, is to be thanked for their assistance in physico-chemical and heavy elements analysis. The Obafemi Awolowo University, Ile-Ife is also acknowledged for providing the conducive atmosphere for the work. Statement of Competing Interests The authors declare that they have no competing interests. R eferences R éférences R eferencias 1. Balkhair, K. S. and Ashraf, M. A. (2016).
