Examination of PM
10
and wind measurements at Lefevre Peninsula Primary
School
The below graphs are polar plots of percent PM
10
particles and percent of wind
direction from data measured at the Environment Protection Authority’s air
monitoring station at Lefevre Peninsula Primary School in July and August
2008.
As described in the report, when the line representing ‘percent particles’ is
further from the centre than the line representing percent of wind from a given
direction, it is an indication that PM
10
particles are higher than average for the
site. It can be seen from the graphs that for the sector including the stockpiles
and Port Adelaide waterfront development (171 to 185 degrees), higher than
average PM
10
readings occurred in:
•
February, November, December 2007; and
•
January, February 2008.
For the sector including other industry (11 to 90 degrees), higher than average
readings occurred in:
•
March, April, June, July, August, September and October 2007; and
•
March, April, May, June, July and August 2008.
Dust management at the development site has improved, and in March to
August 2008 the PM
10
concentrations from the direction of the stockpiles and
Port Adelaide waterfront development has been generally at, or below, average
values for the site. Continued monitoring will determine if PM
10
concentrations
improve. This example highlights the importance of sound management of
impacts on adjoining properties and people at the construction stage of any
development.
