-------
National Summary: NATTS data were collected at 27 locations across the United States,
with sites beginning in 2003 or later (Figure 1) for 19 core HAPs. Over 528,000 concentrations
(primary, secondary, and replicate) were generated and analyzed for this assessment. Pollutant
datasets were scored to assess whether they were suitable for trends analysis. Each
pollutant dataset was evaluated against four MQOs: Completeness; Sensitivity; Bias; and
Precision. Datasets that were suitable (A- or B-rated) for six consecutive years were used for
national trends analysis (Table 1).
National trends were determined by comparing the most recent 3-year blocked averages
(e.g., 2013-2015 vs. 2016-2018) to determine if the NATTS Trends DQO was being met:
To be able to detect a al5percent difference (trend) between the annual mean
concentrations of successive 3-year periods within acceptable levels of decision error.
Of the 19 core HAPs. 18 were assessed for the NATTS Trends DQO. Due to sampling and
analytical issues, acrolein was not considered for trends analysis (Table 2). This assessment
showed that across the network, 15 of those 18 pollutants were decreasing between the
3-year blocks, while two of those pollutants were increasing between the 3-year blocks.
One pollutant did not exhibit a trend.
