Transcript of GIS and Nanotechnology to monitor and measure Air Pollution

Using Nano gas-sensors to monitor and measure Air Pollution in
Eastern province
,
Saudi Arabia

Air pollution in Eastern Province
Proposal
GIS and nanosensors
Nanotechnology
a million time smaller than the length of ant.
- Saudi Arabia is the world's largest producer
and exporter of oil.
- Most are located in Eastern province.
- The presence of industries and manufactoring
plants.
- Although air pollution doesn't reach the danger level now, but the future could be worse.
How could GIS and Nanotechnology
help to monitor and measure air pollution?
Goal
Develop an air pollution monitoring system using low cost nano solid gas sensing system through GIS.
- help in monitoring and measuring air pollutant in Eastern province in order to increase people awareness and support public participation.
- Many applications, industry, medicine, computing, transportaion, aerospace, environment, etc.
- Gas sensors are applied in numerous fields of applications.
- The answer to why use nanotechnology
based solid-state gas sensor is that to increase the gas adsorption and the sensitivity, the surface should be increased.
- the solid-state gas sensor gives out electric signals, related to NOx concentration.

-The NOx concentration values converted from an analog to digital signal by An
A/D
circuit converter.

-The results were utilized for air quality level modeling of the
study area.

Nanosensors
- In terms of practical sinew, solid state gas sensors appear to be the most appropriate.
- The sensors used for detecting air pollutants are usually produced simply by coating a sensing (metal oxide) layer on a substrate with two electrodes. Typical materials are tin oxide (SnO2), zinc oxide (ZnO), titanium oxide (TiO2) and tungsten oxide (WO3) with typical operating temperatures of 200–400 8C
