(2) Analysis on the predicted concentration at sensitive point<br />

EIA for the proposed Hulhule-Male’ Bridge Project<br />

The sensitive point within the scope of evaluation area is the housing area in the northwest of the<br />

project site. Table 6.10 shows the predicted maximum concentration distribution.<br />

Standard value 40 200 30<br />

Standard rate 17.68% 16.02% 0.52%<br />

Accordiong to the prediction, the following values can be derived:<br />

• the annual average concentration of NO 2 is 7.073 μg/m 3 , at standard rate 17.68%;<br />

• the hourly average concentration of NO 2 is 32.032 μg/m 3 , at standard rate 16.02%;<br />

• the hourly average concentration of CO is 0.157 mg/m 3 , at standard rate 0.52%.<br />

These values meet the standard limit in Air quality guidelines-global update 2005 provided by<br />

World Health Organization. Hence, the impact of automobile exhaust and scale of this project is<br />

comparatively limited.<br />
