Environmental Health Indicators 15/12/ What are Environmental Health Indicators (EHI) ? (1/2) EHI: “Measurable units suggesting a relevant and simple relationship between health and environment. Health effects arise from human exposure to environmental pollution.” Cause-consequence relation Changes environment changes health & well- being of people Need to develop EHI to support policy
Environmental Health Indicators 15/12/ What are Environmental Health Indicators (EHI) ? (2/2) Selection criteria for a good EHI: 1.Policy relevance 2.Availability and follow-up of data 3.Simplicity & clarity 4.Sensitivity 5.Validity 6.Reliability & objectivity 7.Specificity
Environmental Health Indicators 15/12/ The DPSEEA-framework Developed by WHO Driving forces Pressure State Exposure Effects Actions
Environmental Health Indicators 15/12/ Inventory of international and national EHI (1/3) State of the art: worldwide overview based on: –International studies on indicators for SD WHO UN OECD EU –National studies: MIRA (‘Environmental report for Flanders’) VRIND (‘Regional indicators for Flanders’) Highlighting themes within E & H, relevant for Flanders
Environmental Health Indicators 15/12/ Inventory of international and national EHI (2/3) Testing proposed indicators to criteria for good indicators: Policy relevance, data availability, simplicity, sensitivity, validity, reliability, specificity To obtain a set indicators to integrate in Flemish EHIS Resulted in core set with 42 relevant indicators for Flanders Classified within the DPSEEA-framework
Environmental Health Indicators 15/12/ Inventory of international and national EHI (3/3) Considered themes: –Outdoor air pollution (17 selected indicators) –Indoor air quality & housing (5) –Noise (4) –Soil pollution (1) –Waste pollution (2) –Water quality (9) –Food safety (1) –Environmental radiation (2) –Smell nuisance (1)
Environmental Health Indicators 15/12/ Filling-in of selected EHI for Flanders (1/2) Filling-in EHI for 3 priority themes with important health impacts: –Outdoor air pollution –Water quality –Food safety
Environmental Health Indicators 15/12/ Filling-in of selected EHI for Flanders (2/2) Implementation: Fact-sheets 1.Results & analysis: Environment & health context: state of the art Policy relevance & context Analysis of the current state 2.Methodology for implementation 3.Data 4.Metadata: Geographical range, time range, frequency datacollection 5.Quality, bottlenecks & weaknesses 6.Alternative indicator(s) 7.Comparison with indicator in other countries
Environmental Health Indicators 15/12/ Filling-in of selected EHI for Flanders a) Outdoor air pollution (1/6) Driving forcesPressureStateExposureEffectAction Energy use by road traffic Yearly emissions of SO 2, NO x and NMVOC Mean year-conc. of SO 2 Population-weighed exceedances of reference concentrations for NO 2 Yearly child mortality due to respiratory diseases Yearly emissions of 8 heavy metals Mean year-conc. of NO 2 Population-weighed exceedances of reference concentrations for PM 10 Yearly mortality due to respiratory diseases Emissions of 17 dioxins Mean year-conc. of PM 10 Population-weighed exceedances of reference concentrations for O 3 Lung cancer incidence Days with exceedance of threshold value for highest mean 8-hours O 3 -conc. Population-weighed exposure to NO 2 DALYs because of PM 10 Mean year-conc. of benzene & 1,3- dichloroethane Population-weighed exposure to PM 10 Mean year-conc. of BaP & PAK’s Population-weighed exposure to ozone Deposition of dioxins Heavy metal concentrations
Environmental Health Indicators 15/12/ a) Outdoor air pollution (2/6) Air_D1: Energy use by road traffic
Environmental Health Indicators 15/12/ a) Outdoor air pollution (3/6) Air_P1: Yearly emissions of SO 2, NO x & NM VOC
Environmental Health Indicators 15/12/ a) Outdoor air pollution (4/6) Air_S2: Mean yearly concentrations of PM 10
Environmental Health Indicators 15/12/ a) Outdoor air pollution (5/6) Air_E xp 5: Population-weighed exposure to ozone
Environmental Health Indicators 15/12/ a) Outdoor air pollution (6/6) Air_E ff 2: Yearly mortality due to respiratory diseases
Environmental Health Indicators 15/12/ Filling-in of selected EHI for Flanders b) Water quality (1/5) Driving forcesPressureStateExposureEffectAction Waste water treatment coverage Exceedance of limit values for microbiological values in surface water (recreational) Outbreaks of waterborne diseases (Waste water treatment coverage) % of surface water measure points with a basic quality for BOD Concentration of pesticides in surface water above the basic guideline value Concentration of pesticides in ground water above the basic guideline value Concentration of pesticides in eel Exceedance of WHO guideline values for drinking water for microbiological parameters Exceedance of WHO guideline values for drinking water for chemical parameters
Environmental Health Indicators 15/12/ b) Water quality (2/5) Water_P1: Waste water treatment coverage
Environmental Health Indicators 15/12/ b) Water quality (3/5) Water_S5: Concentration of pesticides in eel
Environmental Health Indicators 15/12/ b) Water quality (4/5) Water_S6: Exceedance of WHO guideline values for drinking water for microbiological parameters Tap water (100 – 98 %) Well water (100 – 80 %)
Environmental Health Indicators 15/12/ b) Water quality (5/5) Water_E ff 1: Outbreaks of water borne diseases
Environmental Health Indicators 15/12/ Filling-in of selected EHI for Flanders c) Food safety (1/4) Driving forces PressureStateExposureEffectAction Dioxins & PCB’s in cow’s milk Residues of pesticides in food stuffs (fruit & vegetables) Food borne infections Estimated daily intake (pesticides) Monitoring of chemicals in food stuffs Dioxins & PCB’s in breast milk Lead (Pb) in children’s blood Cadmium (Cd) in children’s blood (urine) POP’s in blood Only one indicator was retained after selection, therefore also the alternative indicators are included in this overview (in italic print)
