Determinants of indoor carbonaceous aerosols in homes in the Northeast United States.

ABSTRACT:

Background

Little is known about sources of residential exposure to carbonaceous aerosols, which include black carbon (BC), the elemental carbon core of combustion particles, and organic compounds from biomass combustion (delta carbon).

Objective

Assess the impact of residential characteristics on indoor BC and delta carbon when known sources of combustion (e.g., smoking) are minimized.

Methods

Between November 2012-December 2014, 125 subjects (129 homes) in Northeast USA were recruited and completed a residential characteristics questionnaire. Every 3 months, participants received an automated sampler to measure fine particulate matter (PM_2.5) in their home during a weeklong period (N = 371 indoor air samples) and were also questioned about indoor exposure
