چکیده    background: the release of lead dust during the processing of leadgold ore has become an environmental threat. therefore the protection of miners rsquo; health and their environment required remediation which can be achieved by ranking the risk posed by lead in order to prioritize the allocation of resources during remediation.methods: soil and water samples were collected at brc, brg, bvc, bpa and bfa; bwe, bbh and bpo using stratified random and grab sampling methods. lead concentrations in the samples were determined using aas while health risk index (hri) via ingestion was estimated using usepa equations. the ranking of hri was done using detailed quantitative risk assessment while the difference between the hri and usepa standard were determined using one sample t test.results: the result showed that brc/10, brg/03, bvc/11, bpa/02 and bfa/08 were ranked highest in soil samples, while bwe/02, bbh/09 and bpo/04 were ranked highest in water samples as they posed elevated health risk effects to miners. one sample t test established that the brc, bpa, bfa and bpo were significantly different from united states environmental protection agency (us epa) standard.conclusion: the study discovered that the users of both the lead contaminated soil and water were seriously exposed to potential health risk. it therefore suggested that decision makers should give priority in allocating resources to those sites with elevated lead concentrations during the remediation.
