The World Health Organization has recently released profiles of environmental burden of disease for 192 countries.<h4>Methods</h4>These country profiles provide an estimate of the health impacts from the three major risk factors 'unsafe water, sanitation & hygiene', 'indoor air pollution from solid fuel use' and 'outdoor air pollution'. The profiles also provide an estimate of preventable health impacts by the environment as a whole. While the estimates for the three risk factors are based on country exposures, the estimates of health gains for total environmental improvements are based on a review of the literature supplemented by Environmental health : a global access science source7https://www.ebi.ac.uk/biostudies/studies/S-EPMC2276491biostudies-literatureThe impact of the environment on health by country: a meta-synthesis.PMC2276491Corvalan CPruss-Ustun ABonjour SfalseThe impact of the environment on health by country: a meta-synthesis.<h4>Background</h4>Health gains that environmental interventions could achieve are main questions when choosing environmental health action to prevent disease.
