DYNAMIC AIR POLLUTION PREDICTION SYSTEM (DAPPS)
1. How do you think the system It could provide baseline information, which could be
would be of use or benefit to you or interrelated with our company Environmental
your work? Management System.
It will assist to measure ambient emissions in the
Bellville South area.
Hopefully DAPPS would lead to a situation where
people will benefit from improved health.
Improve planning (in future air quality plans would be
drafted). Assist with compliance monitoring and
enforcement state of environment. Assist in decision-
making (authorizations e.g. EIAs)
It would benefit in understanding local air pollution
problems better by enabling the real display of air
pollution as well as predicting future episodes
Validate air quality data
Me: Improved quality of life
Work: More tools to undertake projects in air quality
We are dealing with Community Organisations, other are
involve to Environment Justice and we need to inform
[public about] what is happening around their areas
2. How would you use the system? We are also a member of Bellville South Environmental
Forum (BELSEF) – this information will be very
valuable to all members.
To monitor ambient emissions in the Bellville South
To validate Air Quality data.
Presently we would use the system for the benefit of the
residents in our area and to bring pressure to bear on the
As a decision – support tool in planning, policy-making
(legislation), target and standard setting predict
Hopefully as a desktop tool to predict air pollution both
for personal information and for communication to
others. Implement stricter controls where necessary - to
validate Air Quality data.
Would like to investigate the benefits of new vehicle and
fuel technologies using two scenario function.
Use it as information in the notice board of our center
and how they use it to input to the system.
3. Which pollutant sources would Nox, SOx, VOC’s (Ozone)
you like to be included PM10 (Soiling index)
SOx, NOx, SO2 particulate matter.
All NO, NO2, O3, CO, SO2, VOC’s
Volatile organic compounds (VOC’s)
NOx, SOx, PM, ozone, CO2
Industrial, Vehicular, Domestic, other eg. Tyre burning
PM10, PM2.5, PM1, PMO.1, SO2, NO, NO2, VOC’s,
4. How would you like the Available via Internet.
information communicated? Electronically
Website (electronically) – scientifically in a popular
format – radio, television, newspapers
Internet, newspaper, radio, television
Spreadsheet database, internet site
Through paper and radios that include community media.
If you could build a dynamic scientific machine e.g.
ATM that people can use.
5. How you like information In relation to acceptable levels i.e. WHO, DEAT
displayed? Concentrations? Concentration, health indicators and historical data
Averaging periods? Health averaging periods will be useful.
Indicators? Historical Data? Indicators to state if peak or average
All of the above with a preference for health indicators.
All data graphically represented,
Averaging periods – daily
Health indicators – asthma. Other allergies (hay fever,
Health indicators – API
Graphs and Tables
Concentrations, historical data certainly including diurnal
averages, peak and minimum values. Comparisons
against health standards in the database will definitely be
All of the above.
6. Do you have data that might be Yes, emission data i.e. boilers is available to the public.
of use to the Project? (For example, Domestic fuel through FFS
traffic data, domestic fuel use data, Industrial fuel through FFS
road networks, demographic data Yes (Validated Air Quality data)
(population distribution etc.), and Civic Ass of Bellville has medical records of residents in
backyard burning?) the area taken over a period of time, which might be an
indicator for the Bellville South area.
Road networks – approach DAWC Dept. of Transport –
can provide you with contact people
South African National Roads Agency
Industrial emission inventory
Mobile source emission factors, disaggregated vehicle
population data, literature on established inventory
7. Any other comments? Suggest that this project is run in close association with
BELSEF. BELSEF is looking at funding an air
monitoring station, which could be located in the
Bellville South area. The two initiatives should be
aligned to compliment one another.
We believe that ultimately government levels for
pollution must be adjusted to be more people orientated.
Present standards in third world countries are all big
See it as a very useful tool. Many benefits, but noting the
European mobile source emission factors should be
applied with great caution. Our vehicles are on average
beyond the useful life of the vehicle as determined in
