Abdulgadir Elnajdi | Spatial analysis of lead-contaminated soil properties using geographic information system (GIS)

The study of the health issues caused by environmental factors such as lead-contaminated soil requires reliable information on soil properties' spatial distribution. Lead-contaminated soil resulting from gasoline, paint, and industrial pollution is still a severe source of lead for young children in the United States. Lead is associated with health risks such as kidney diseases, bone diseases, and affected regions inside the brain responsible for executive functions in the human body. Centers for Disease Control and Prevention (CDC) highly advise that public health measures start when a child's blood lead level is five µg/dL. A blood lead concentration (BLL) of greater than ten µg/dL at an early age could cause long-lasting health effects. In 2014, children in Indiana were screened for Lead, and approximately 4.3 % (0 1,765 out of 40,811) Hoosier children were at or above the CDC standard of five µg/dL (Health and Program, 2014). The lead levels found in Muncie's soil are concerning. The evaluation of the spatial distribution of soil properties [soil lead content, soil pH, soil texture, Etc.] is essential to assess the health concerns in Muncie, and it is one of the bases for decision and policymakers to make designs and strategies to fix the issues.

Researchers in environmental monitoring with geographic information system (GIS) can generate high-quality maps. The objective of this study is to investigate the interactions between total lead and bioaccessible Pb with blood lead levels of Muncie residents. Furthermore, examine the soil properties such as soil texture, pH, and organic matters to add more information about the possibility of lead mobility in Muncie's soil.
