Introduction

  • Oxidative stress (OS) is an important consequence of exposure to toxic metals.
  • It is unclear to what extent low-level exposure to multiple metals contributes to OS in young children.
  • There is little understanding of whether diet rich in antioxidant nutrients reduces metal-induced OS in children.

    Childhood exposure to metals, pesticides and other neurotoxins can result in irreversible neuropsychological impairments. Whereas metal exposures have declined in the general U.S. population and significant progress has been made in the reduction of certain metals in the environment, other environmental exposures, like pesticides and air pollution, are continuing to be a problem. These exposures often occur in the context of low family resources, poor nutrition, or unsafe neighborhoods.
