FUTURE DIRECTIONS
Indoor pollution will continue to be an essential field for health studies and interventions, because exposure
to varied indoor substances will likely increase in coming years. Better studies dealing with genetic susceptibility
to indoor pollutants, their carcinogenic effect and their impact on lung growth, lung development and, later on, lung aging, are also required. To answer several of these questions, longitudinal studies are required. A formal evaluation of improved stove programs from many viewpoints is also essential to improve guidance for countries and communities as they
implement their own programs. Although local adaptation of programs will always be required, improved biomass stoves will likely be more common, with better community acceptance, reduced burden on forests, and increased spare time for homemakers
