TSP Annual Average Assessment
TSP monitors were sampled and analysed in accordance with AS 3580.9.3 (2003). The TSP impact
assessment criterion is an annual average concentration of 90μg/m 3 . TSP results are shown in Table 19 and
Figure 23 to Figure 24. During 2009 all sites were in compliance with the long term criterion of 90μg/m 3 .
Generally TSP results were higher in 2009 compared with 2008. A decrease in annual rainfall in 2009
compared with 2008 is likely to have contributed to higher dust levels, particularly during August through to
November which typically coincides with hot and dry weather conditions.
