This data publication contains emission factors for 195 gaseous and particulate compounds measured during the burning of three mixtures of manzanita wood and low-density polyethylene plastic (LDPE, agricultural plastic) in a laboratory. The mixtures consisted of 2 kilograms (kg) of manzanita wood paired with 0, 5 or 50 grams (gm) LDPE. Mixtures were burned in a basket and smoke was collected above the fire. A total of nine fires (3 mixtures x 3 replications) were burned on Nov. 4, 2008 using a randomized complete block design. Smoke emitted from the fires was concentrated into a small stack system from which gas and particulate samples were extracted. Various filters and real-time instruments were used to collect the emissions. Subsequent analyses of filters and gases occurred in analytical laboratories at the University of California – Riverside over several months. Emission factors are expressed relative to kg of carbon dioxide produced. The data contains information on individual compounds which can be classified into alkanes, alkenes, alkynes, aldehydes, ketones, cycloalkanes, cycloalkenes, monoaromatic and polyaromatic hydrocarbons in addition to elemental carbon, organic carbon, particulate matter, carbon monoxide, and NOx.
