Exposure: Whether and how a human or other organism comes into contact with a chemical, usually by eating or drinking it, inhaling it, or touching it and having it penetrate the skin

Location of Surface O3 Monitoring Sites
Air Quality Management 24
Photochemical Assessment Monitoring Stations (PAMS)
Site #1 - Upwind and background characterization site.Site #2 - Maximum ozone precursor emissions impact site. Site #3 - Maximum ozone concentration site. These sites are intended to monitor maximum ozone concentrations occurring downwind from the area of maximum precursor emissions.Site #4 - Extreme downwind monitoring site. These sites are established to characterize the extreme downwind transported ozone and its precursor concentrations exiting the area and will identify those areas which are potentially contributing to overwhelming ozone transport into other areas.

Air Quality Models• Air quality models use mathematical
and numerical techniques to simulate the physical and chemical processes that affect air pollutants as they disperse and react in the atmosphere.
• inputs of meteorological data• source information• emission rates • stack height • models are designed to characterize
primary pollutants • secondary pollutants that are formed
as a result of complex chemical reactions within the atmosphere
Air Quality Management 26
Surface Data• Surface data are meteorological data
that are measured at the earth’s surface (technically, somewhere between the ground level and 10m).
• data contains physical parameters • Temperature• dew point• wind direction• wind speed• cloud cover• cloud layer(s)• Visibility• current weather• precipitation amount• Surface data are reported by the
National Weather Service for each hour

The World Bank Assessment Report (Pakistan)
• Mean annual cost of Environmental and Natural Resource Damage is about Rs. 365 billion or 6% of GDP
• Air pollution contributes 1/3 to the total damage
• Rs. 67 billion for Indoor air pollution
• Rs. 65 billion for Urban air pollution
• Annually urban air pollution causes– 22,000 deaths among adults – 700 deaths among young

Low Volume Air Sampler
Particulate Matter Sampling
The concentration of Total Suspended Particulate was calculated using the following formula (40 CFR Appendix B, Part 50, USEPA)
(µg/m3)
where,TSP is mass concentration of total suspended particulate matter (µg/m3)Wi is initial weight of clean filter (g)Wf is final weight of exposed filter (g)V is the sampled air volume (m3) 106 is for conversion of g to µg
