Situation Outline

• Problem managing over the same area urban
  dwellings, industrial premises and waste
  management plants
• Great concern about adverse effects caused by air
  pollutants
• No satisfactory scientific evidence about the
  effects of pollutants from waste incineration on
  human health, nor the space dispersion

The project

• ENHance Health (Environmental Health Surveillance
  System in urban areas near incinerators and
  industrial premises)
• EU INTERREG IIIC funded
• Main objective the Processing of Guidelines and
  Good Practices for implementing
  Environmental-Health Surveillance Systems

EHS System Overview

• GIS web-based survey system for environmental
  surveillance
• There are two parts
• Administrative application addressed to
  scientific experts for data entry
• Application accessible to authorized users for
  querying the system and monitoring pollution
  levels
• System Components
• Application Web Server
• Database (GIS data, environmental
  meteorological data)

EHSS Administration Pages

• Management of under study factors (environmental
  and epidemiological e.g. CO, NO2, ARI etc)
• Insert a new factor
• Delete an existent factor
• Modify a factor
• Input of records for the measured level of a
  factor
• Manually for each record
• Automatically for many records, using a file in a
  predefined format
• Input of meteorological files as .met files

EHSS Surveillance Pages

• Query the system for the levels of the under
  study factors near the incinerators for a desired
  period
• Statistics per day, month or year for the
  requested period
• Colored map representation of the factor levels
  (green, yellow, red)
• Two modes of surveillance data measured in a
  specific point (default) and data measured in a
  radius around the incinerator
• Alerts in case the level of the factor is higher
  than the maximum allowed. Meteorological data
  presented in this case
• CUSUM alert control
• View all produced alerts classified per region,
  factor and date

EHSS Surveillance Pages Combinative Analysis

• How is environmental pollution related to health
  problems?
• The system allows a combinative analysis that
  helps scientists discover possible relations
• In case an alert is produced after a query about
  an environmental factor there is the option to
  view the results for the same query for all
  epidemiological factors and vice versa
• Scientists can compare the levels between
  environmental and epidemiological factors

EHSS Surveillance Pages CUSUM Analysis

• CUSUM statistical control method in order to
  detect sharp changes in the level of a measured
  factor
• An alert is produced if a sharp change is detected

Case Study

• The system was applied for specific territories
  of Italy, Poland and Hungary
• The waste incinerator plants, are located nearby
  urban settlements
• In case of Italy, as results are combined with
  the scientific evidences that are part of the
  strategy for Risk communication to citizens, a
  participative and sustainable policy model is
  currently under development
