abstract = {The emissions of volatile organic compounds (VOCs) from
volatile chemical products (VCPs) – specifically personal
care products, cleaning agents, coatings, adhesives, and
pesticides – are emerging as the largest source of
petroleum-derived organic carbon in US cities. Previous work
has shown that the ambient concentration of markers for most
VCP categories correlates strongly with population density,
except for VOCs predominantly originating from solvent- and
water-borne coatings (e.g., parachlorobenzotrifluoride
(PCBTF) and Texanol®, respectively). Instead, these
enhancements were dominated by distinct emission events
likely driven by industrial usage patterns, such as
construction activity. In this work, the headspace of a
variety of coating products was analyzed using a
proton-transfer-reaction time-of-flight mass spectrometer
(PTR-ToF-MS) and a gas chromatography (GC) preseparation
front end to identify composition differences for various
coating types (e.g., paints, primers, sealers, and stains).
Evaporation experiments of several products showed high
initial VOC emission rates, and for the length of these
experiments, the majority of the VOC mass was emitted during
the first few hours following application. The percentage of
mass emitted as measured VOCs $(<1 \%$ to $83 \%)$
mirrored the VOC content reported by the manufacturer (<5 to
550 g L−1). Ambient and laboratory measurements, usage
trends, and ingredients compiled from architectural coatings
surveys show that both PCBTF and Texanol account for
$∼10 \%$ of the total VOC ingredient sales and,
therefore, can be useful tracers for solvent- and
water-borne coatings.},
