    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.
