Abstract:Former industrial sites are often reclaimed for new homes and other occupational uses. Such sites may still contain toxic chemicals that could put the health of the community at risk. The persistence of these residual chemicals and their effects on human health must not be underestimated. Hence, there is a need to analyze such sites to ensure that the public health will not be put at risk. It is also essential that the levels of release of heavy metals into the environment be monitored and regulated. In this study the lead (Pb) concentration in soil from a small 15th-century industrial site was determined to assess and evaluate its occupational and environmental health implications. Concentrations of Pb measured by atomic absorption spectroscopy (AAS) and inductively coupled plasmaemission spectroscopy (ICP-AES) techniques were 4,298.755 mg/L (SD 0.316; RSD 0.5%) and 4,300 mg/L (SD 0.3809; RSD 0.8%), respectively, both above the safe limit. It is concluded that reclaiming a disused industrial site without adequate soil analysis and proper remediation would be likely to pose occupational and environmental health risks.
