Introduction
• Ozone is a bluish gas composed of 3 atoms of oxygen (O3)
• Ozone gas can be created or destroyed by the UV rays
2www.ozonetechnologies.com.au
The ozone layer, situated in the stratosphere about 15-30 km above the earth’s surface.
Stratospheric Ozone
• Good ozone
• Protects living organisms by absorption of harmfull UV-B from the sun
3
• The ozone layer is gradually being destroyed by manmade chemicals ODS: CFCs, HCFCs, halons, methyl bromide, etc.

• At the Ground Level Ozone identify as a Oxidant (Ox)
• A harmfull pollutant
• Not emitted directly into the air.
• Created by chemical reactions between NOx & VOC in the presence of sunlight.
• Reach unhealthy level on hot sunny days in urban env.
• Can be transported by wind.
Major sources of NOx & VOC : emissions from industrial facilities & electric utilities, motor vehicle exhaust, gasoline vapors, and chemical solvents.
Health Effects (1)
7
Over exposure of UV light :
• Increases the risk of eye damage such as cataracts, leading cause to blindness.– Higher prevalence of cataracts after
30
• Premature aging of the skin
• Increase the risk to malignant and non malignant (benign) skin cancer.– Unrepaired DNA damage
mutations skin cancer
• Suppressed immune system 1) www.ldeo.columbia.du2) www.mcbrideandmccreesh.com3) www.skincancer.org

Health Effects (2)
• Health problem for children, elderly, and lung disease patients
difficult to breath, coughing, sore of throat, inflame the airways, damage the lungs

Environmental Effects
9
• Prolonged exposure may cause serious damage on plants and crops.
• To damage the aquatic ecosystem (plankton, aquatic plants, fish larvae) and affect the marine food chain.
• Faster degradation of materials (paints, tires, sidewall)
Monitoring Activities of Ground Level Ozone in Indonesia
10
Research Activities
• EMC/(Center for Research and Development of Environmental and laboratory quality) reported air quality monitoring in Serpong as Pollution Standard Index (ISPU) in 1999 until 2002.
• MoE conducted AQMS monitoring system since 1999 in 10 places over the country : Jakarta, Bandung, Semarang, Surabaya, Denpasar, Medan, Pekanbaru, Jambi, Pontianak , and Palangkaraya. Each city has 5 fixed stations.
• To monitor general ambient air quality such as : PM-10, NO2, SO2, O3, CO & meteorological condition (WS, WD, RH, and global radiation).
• Sites: Jakarta, Surabaya, Palangkaraya, Pontianak and Pekanbaruremain to report the monitoring result to MoE. No report from other sites due to several technical issues.

Several Reports of Ozone Monitoring
22
Current Issues
• Monitoring Instrument:
– Technical problem, maintenance, and policy issues
– Outdated equipment
– Human resources: lack of competence
– Few reports of the effects on humans & environment
23
Future Plan
• To strengthen the facilities, infrastructure and human resources
• To have the research collaboration regarding to ground level ozone
– Effects on humans & environment
– Modelling to manage ground level ozone
