Bronx (#1), NY NATTS Network Assessment Review
Established 2003: VOCs
o Carbonyls in 2004
o Chromium VI added in 2007; ended in in 2013
o PMio Metals added in 2007
o PAHs added in 2008
For the NATTS Network Assessment (2003-2018):
o 17 of 18 Method Quality Objective (MQO) Core HAPs were included in the national trends
¦ Chromium VI: Did not have six consecutive years of data
o 169 of 206 pollutant datasets were suitable for trends analysis.
o Annual Average and 3-Year Rolling Average Concentrations were generally decreasing over time for the
majority of pollutants (arsenic (PMio), benzene, beryllium (PMio), 1,3-butadiene, cadmium (PMio), lead
(PMio), manganese (PMio), naphthalene, nickel (PMio), tetrachloroethylene, and trichloroethylene).
o -90% Reporting of Datasets
Method Quality Objectives (MQO): 2003-2018
o Completeness: Met 85% completeness in 176 of 206 pollutant datasets
o Method Detection Limits: Met MDL Target Ratio of 1.00 in 208 of 245 pollutant datasets
o Bias: Met ±25% for 182 of 197 pollutant datasets
o Overall Method Precision: Met <15% CV for 87 of 117 pollutant datasets
o Analytical Method Precision: Met <15% CV for 99 of 127 pollutant datasets

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.

a: Although this pollutant was sampled for at this site and year, the laboratory equipment was not operating at the time the Proficiency Test sample was sent.
b: No Proficiency Test samples were sent for this pollutant and year.
c: Pollutant was expected, but not sampled at this site for this year.
d: Proficiency Test results are from the National Contract Lab for EPA's School Air Toxics Monitoring Program. The %Difference was -5.55% in 2009 and 10.53% in 2010.
e: The Proficiency Test sample for this pollutant was 0; the site reported a concentration as "< MDL", rather than 0. EPA accepted this result.
f: Although a Proficiency Test sample was sent to the lab supporting this site and year, the results were nullified by EPA due to QA issues.

A-rated:< 15% CV
B-rated: Between 15%CV to25% CV
Does Not Meet: >25% CV or did not report Precision (required in the NATTS Workplan Template since 2012)
No data available
a: Per the NATTS Workplan template, analytical replicates were required to be reported to AQS for this sampling year
b: The primary and/or replicate value were less than the MDL, so no calculation could be made.
