Making efforts towards creating a human and environmentally-friendly airport

>> Monitoring of the air quality
Three observation stations have been established on the opposite coast, and nitrogen dioxide,suspended particulate matter(SPM), and other atmospheric pollutants are measured continuously together with wind direction and wind speed.

Monitoring item	Monitoring location	Frequency
Nitrogen oxides (nitrogen monoxide, nitrogen dioxide), SPM, photochemical oxidants, hydrocarbons (methane,nonmethane), wind direction, wind speed	1location	Continuous monitoring

>> Monitoring of the water quality
About ten items, including the total amount of nitrogen, phosphorus etc. are monitored 4 times per a year.
I

Monitoring item	Monitoring location	Frequency
Transparency, water temperature, salt content, pH, chemical oxygen demand, sulfides, total nitrogen, total phosphorus, chlorophyll-a, suspended solids	Inner sea area: 3points	2 times/year

Monitoring of the water quality

Measuring on board

>> Monitoring of sea bottom sediment
Four times a year, monitoring in regard to eight items, such as grain composition, chemical oxygen demand, etc sulfides, are monitored in the sea around the airport island.

Monitoring item	Monitoring location	Frequency
Sludge temperature, solid residue, grain composition, pH, chemical oxygen demand, sulfides, total nitrogen, total phosphorus	Inner sea area: 3points	2 times/year

Bottom sampler

Sampled sediment

>> Monitoring of marine life
Monitoring of plankton, fishery animals, sea shore organism, etc. four times a year.

Monitoring item	Monitoring location	Frequency
Plant plankton, animal plankton	Inner sea area: 2points	suspended
bottom organizms	Inner sea area: 3points	2times/year

>> Monitoring of land animals
Monitoring of the flying of birds over the airport island and around it, their breeding, falcon routes, etc.

Monitoring item	Monitoring range	Monitoring location	Frequency
Flying and breeding of birds	On the first airport island	Fixed points and investigation lines	suspended
Flying and breeding of birds	Ocean around the airport island	Investigation lines
Falcons	Falcon routes	1 location

Investigation of the traffic volume
Suitable investigations are performed in order to grasp the influence of the construction] related vehicles onto the road environment.

>> Monitoring of the aircraft noise

The aircraft noise is measured at 11 normal measuring stations and 20 periodic inspection locations around airport.
