Summary
The economic costs of adverse health effects associated with prenatal mercury/methyl mercury exposure were determined using cost analysis. The costs related to diminished intelligence was estimated to be $8.7 billion annually, and costs of excess mental retardation cases is $2.0 billion annually. These results suggest that more stringent mercury policy options would prevent thousands of mental retardation cases and save billions of dollars over the next 25 years.
Population
Infants (≤ 1 year)

Health Outcomes

  • Neurological/cognitive outcomes (IQ deficits, mental retardation)

Environmental Agents

List of Environmental Agents:

  • Metals (mercury/methyl mercury)

Source of Environmental Agents:

  • Industrial mercury emissions (American coal-fired power plants)

Economic Evaluation / Methods and Source

Type:

  • Cost analysis (CA)

Cost Measured:

  • IQ deficits associated with prenatal mercury exposure
  • economic costs associated with IQ deficits
  • costs of excess mental retardation (MR) cases
  • cost of caring for MR children

Potential Cost Measures: (Not available)

Benefits Measures: (Not available)

Potential Benefits:

  • Policies (e.g., EPAs Clean Air Mercury Rule) will likely result in the following benefits — averted cases of mental retardation
  • dollars saved/costs averted related to lost economic productivity, special education, and healthcare.

Models Used:

  • Environmentally Attributable Fraction (EAF) model
  • linear dose-response model used by the National Research Council (NRC) to set reference dose for mercury exposure

Methods Used:

  • The authors assessed the impact of industrial mercury emissions on children's health. Using an environmentally attributable fraction (EAF) model, the authors — 1) reviewed the adverse effects of MeHg exposure; 2) estimated the costs of the adverse effects (IQ decrements and mental retardation) and subsequently applied a further fraction to parse out the cost of anthropogenic MeHg exposure resulting from emissions of American electrical generation facilities; 3) used previously published data to obtain estimates about mercury concentrations in women of child-bearing age and mental retardation cases/prevalence in US; and 4) conducted sensitivity analysis with lower bound and upper bounds for estimating the costs to children with estimated cord blood concentrations.
