- Air pollutants negatively impact human health, prompting a study on effective policies and technologies to mitigate these effects in densely populated areas of South Africa.
- The research ranks interventions, finding that low-cost household measures, like proper coal usage and roof insulation, are more efficient than industrial policies.
- The study suggests prioritizing household interventions before pursuing additional industry regulations, as current industrial measures do not provide sufficient health care cost justification.
