This study aimed at evaluating the carcinogenic and non-carcinogenic risk of the study area using X-Ray fluoroscopy. The results showed that, mean concentration level in the area was in decreasing order Cu(342.2) &gt; Cr(486.6) &gt; Ni(339.1) &gt; Zn(421.6) &gt;Pb(331) &gt; Cd(336.6) &gt; As(31.7). The Hazard Quotient (HQ) was all recorded to be low except ingestion adult which was higher than unity. The Hazard Index (HI) was also recorded to be 2.3 a value greater than one (&gt;&gt;1). This makes non-carcinogenic effects significant to the population and poses serious effects in the area under study. The total excess life cancer risk was found to be (5.0 x 10<sup>-2</sup>), a value greater than that of U.S (1.0x10<sup>-4</sup> to 1.0x10<sup>-6</sup>) and above that of South Africa (5.0x10<sup>-6</sup>). This implies that there is a probability that one person in 1,000 may be affected. Regular monitoring and evaluation of the soils and the crops cultivated at the sample locations is recommended.</p> 2020-05-23T00:00:00+00:00 ##submission.copyrightStatement##
