* Health-based benchmarks for wipe samples were not developed for the following elements (classified as essential nutrients): calcium, magnesium, potassium, and sodium. These substances play critical roles in the body's normal function as evidenced by the adverse health outcomes associated with deficiency. Because they possess relatively low oral toxicity, the quantitative toxicity criteria needed to develop health-based benchmarks for these essential nutrients have not been established.
