Just Accepted “Just Accepted” manuscripts have been peer-reviewed and accepted for publication. They are posted online prior to technical editing, formatting for publication and author proofing. The American Chemical Society provides “Just Accepted” as a free service to the research community to expedite the dissemination of scientific material as soon as possible after acceptance. “Just Accepted” manuscripts appear in full in PDF format accompanied by an HTML abstract. “Just Accepted” manuscripts have been fully peer reviewed, but should not be considered the official version of record. They are accessible to all readers and citable by the Digital Object Identifier (DOI®). “Just Accepted” is an optional service offered to authors. Therefore, the “Just Accepted” Web site may not include all articles that will be published in the journal. After a manuscript is technically edited and formatted, it will be removed from the “Just Accepted” Web site and published as an ASAP article. Note that technical editing may introduce minor changes to the manuscript text and/or graphics which could affect content, and all legal disclaimers and ethical guidelines that apply to the journal pertain.

Abstract

26

Ultrafine particle (UFP) emissions and particle number size distributions (PNSD) are critical in

27

the evaluation of air pollution impacts; however, data on UFP number emissions from

28

cookstoves, which are a major source of many pollutants, are limited. In this study, eleven fuel-

29

stove combinations covering a variety of fuels and different stoves are investigated for UFP

30

emissions and PNSD. Combustion of LPG and alcohol (~1011 particles per useful energy

31

delivered, particles/MJd), and kerosene (~1013 particles/MJd) produced emissions that were

32

lower by 2-3 orders of magnitude than solid fuels (1014-1015 particles/MJd). Three different

33

PNSD types; unimodal distributions with peaks ~30-40 nm, unimodal distributions with peaks
0.05, Figure S1). This is also the

149

case for EFs measured for most fuel/stove combinations at high- and low-power phases, with

150

the exceptions of [Kero-WS] and [Char-NDS] (p
