The occurrence of some metals in the soil is very important, either in small quantities (micro-nutrients) or in very great amount (macro-nutrients), for the growth of plants, who are the primary producers of food for all living things. As good as this is, occurence of some other metals called heavy metals, are very poisonous at certain concentrations. The poisonous metals are usually the non-important ions in ecological systems. This study has shown that it is possible for some of these poisonous metals to be in the soil of the environments around a waste dumpsite, which can lead to various health effects on the living things around such areas including humans.
This study is important as it exposes the possibility of occurrence of these toxic heavy metals in very great concentrations within the topsoil layer of such communities that are within the fringes of waste dumpsite as the one in this study. This knowledge is very important to survival and good health of residents of such communities and informative to policy makers in the state where such exists.
This article is a baseline study, which is highly informative about the effect of indiscriminate disposal of toxic wastes to the environment, on the inhabitants of such environments. Some of the health effects of exposure to some of these metals mentioned in this article is due to continuous ignorant interactions of the people with consumables originating from polluted soil such as the one in this article. This article is a warning of possibility of outbreak of health issue among the residents of Olodo community as a result of the exposure to toxic heavy metals from the waste dumpsite.
