environmental health areas of concern
Environmental Health - Areas of Concern
  • Outdoor Air Pollution (OAP)
  • Indoor Air Pollution (IAP)
  • Water Pollution, Sanitation and Hygiene (WSH)
basic outline of the study for each area of concern
Basic Outline of the Study (for each area of concern)
  • The basic issues and state of the environment
  • Level of exposure to pollutants and, sanitation and hygiene problems in the Philippines
  • Morbidity Incidence
  • Economic cost of Morbidity
  • Mortality Incidence due to environment
  • Economic cost of mortality
  • Suggested policy interventions
  • Economic evaluation of policy interventions
how the study was done
How the study was done…
  • Calculate the proportion of total cases of illnesses that are attributable to pollution, sanitation and hygiene
  • Using WHO and Philippine data, determine the cost of treatment and foregone income from illnesses and premature deaths
  • Aggregate the economic costs and values from these calculations
sources of pm emissions
Sources of PM emissions

what we know so far
What we know so far…
  • There has been a drop in PM emissions in Metro Manila since 2003
  • The number of vehicles in the country is growing
  • Diesel contributes more to PM than gasoline
  • Main source of PM emissions in the country – 2 stroke-tricycles
  • The bulk of vehicles in the country are the tricycles followed by utility vehicles
morbidity cases oap
Morbidity Cases - OAP

Total: 119,080

potential interventions to curb oap
Potential Interventions to curb OAP
  • Inspection and maintenance (I/M) programs
  • Installation of pollution control devices
  • Rehabilitation of Current Traffic Management System
  • Investments in Additional Mass Transport System
morbidity cases iap
Morbidity Cases - IAP

Total: 114,665

potential interventions to curb impacts of iap
Potential Interventions to curb impacts of IAP
  • Promote improved household living environment (improved ventilation)
  • Promote use of “improved” stoves
  • Effect changes in cooking practices
