Abstract:
There are many known health effects linked to lead exposure, such as impaired neurological development in children. Despite this, piston-engine airplanes still contain tetraethyl lead in their gasoline, as there is currently no safe alternative. Because it is known that close exposure to lead can influence the public health of the community, this study researches if there is a link between proximity to an airport and soil health in gardens. Five gardens near the Tucson International Airport were studied, along with two control gardens. The results indicate that there is no correlation between leaded gasoline in airplanes and lead contamination in garden soils, with each soil in the study containing between 7.19-12.99 milligrams per kilogram (mg/kg) lead. This is minimal, compared to the EPA's recommended exposure limit of 400 mg/kg lead and more stringent state guidelines of 100 mg/kg, indicating that there is not a strong public health impact. In addition, four other metals were analyzed. Beryllium was present in amounts of 0.24-0.41 mg/kg, zinc between 42.40-130.05 mg/kg, arsenic between 2.04-5.25 mg/kg, and cadmium between 0.17-1.04 mg/kg. All of these results were below recommended guidelines and were in the category of healthy, uncontaminated soils.
