The study of fugitive dust impact under construction

Title The study of fugitive dust impact under the secondary construction of Inchon International Airport

Purpose The prediction of fugitive dust concentration on the airport f

acility & the residence site nearby construction site of the Inchon airport extension and mountain cutting (the source of fill up the field)

The possible abrasion influence for aircraft Period

Oct. 2002 ~ July 2003 (10 months)

2005 & 2007 year

Meteorological data & Parameter for Model

Use the ISCST3 (Inderstrial Source Complex) Model Gaussian model Useful for non-reaction pollutant

Meteorological data The data from the AWS at Inchon airport(2001) Wind direction, wind speed, temp., stability, mixing height

Domain 13km x 10km

Receptor Grid (500m by 500m)

Add on the receptor point at Airport facility & residence Pollutant

PM10 Annual/24h average conc.

2005 Annual conc. Contour of PM10

2007 Annual conc. Contour of PM10

Discussion In 2005, the level of ambient PM10 conc. would not meet

air quality standard The residence area nearby the source (mountain) In

annual/24h average Air quality standard of PM10

70㎛ /㎥ (annual avg.) and 120㎛ /㎥ (24h avg.) In 2007, meet air quality standard at the residence and the

airport Crush Plant is the important source of PM10 Dust influence for aircraft

Very little reference are available so far Based on wind-blown dust events

experience(100~500㎍ /㎥ ), the level of conc. from the construction (maximum 200㎍ /㎥ ) may not be very critical.

Need further investigation

The study of the Long-range Transboundary Air Pollutant in the background conc. area

Purpose Building monitoring Network for the long-

range transport air pollution in north-east Asia (Korea, China and Japan)

The measurement of air pollutant conc. in remote area

The analysis of the behavior of air pollutant in conjunction with the meteorological analysis

Compilation of monitoring data

The Location of observation site

The Location of observation site 5 site (Ganghwa, Taean, Geoje, Goseong, Gosan)

History 1st project(1995~1999)

The study of the long-range transboundary air pollutant in north-east Asia & collaboration for preservation of Environment

1st year(1995) Determination of measurement method at surface station and ana

lysis. 2nd year(1996)

Continue measurement Add DMS meteorological analysis international research

3rd year(1997) Add measurement station(3 in Korea, 1 in China) Total 7 measurement station Add PM10 on measurement list Measurement DMS(at Gosan), MSA(at Ganghwa) & E

stimate emission amount Estimate incoming quantity of air pollutant

4th year intensively measurement in 3 period at 6 station Measurement Every 6 day Estimate dry deposition Estimate incoming quantity of air pollutant Comparison with other country’s data Enhancing data quality

2nd project(2000~2003) The study of the Long-range Transboundary Air Pollutant in t

he background conc. area 1st year(2000)

Continue analysis for 1st Project (for four years) Measurement of aerosol size distribution VOCs monitoring Measurement in background area

2nd year(2001) Enhancing cooperative network of remote monitoring for be

tter data quality in background area 3rd year(2002)

Back trajectory Analysis from PM2.5 mass conc. & ionic conc. of soluble property

Intensively measurement of PM2.5 (March, April, December)

MESUREMENT ITEMS Measurement Categories

PM10, PM2.5, aerosol size distribution, elemental properties, major gas species, VOCs, carbon species and metals

Each category have been measured for once a day Analysis Categories

Mass conc. (PM10, PM2.5. size distribution) Water-soluble ionic elements of PM10, PM2.5

Cl-, NO3-, SO42-, HCl, HNO3, NH3, Na+, NH4+, K+, Mg2+, Ca2+ Carbon analyze

OC, EC (Organic Carbon, Elemental Carbon) metals elements

Fe, Al, Ca, K, Na, Mg, S, Zn, Pb, Ti, Mn, Cu, V, Sr, Ni, Ba, Cd, Cr VOCs

VOCs were detected which based on POCP (Photochemical Ozone Creation Potential)

Measurement period Three times a year (During consequently 15days-April, 10days-May, 10days-no

vember) West wind is the prevaily wind direction for spring/fall

Plan

Need for quantitative transport analysis LRT analysis using CTM is required

(ex. STEM) Mainly focus on aerosols (my interest) Gas phases modeling will be conducted

by one of my colleague. Initial step for STEM will be a tracer

mode for aerosol.

What I did in Iowa Learning “how to” run MM5 Learning “how to” import emission data Learning “how to” run STEM

What I will do in Seoul Install & Run MM5/STEM Building cluster system (maybe 5 node or

more)
