Abstract
Receptor modelling and risk assessment of volatile organic compounds measured at a regional background site in South Africa North-West University's research published in Atmospheric Environment
Highlights
positive matrix factorisation (PMF) analysis indicated ten meaningful factor solutions, with five factors being associated with biogenic emissions and five with anthropogenic sources
In order to develop climate change reduction strategies and to assess the impacts of Volatile organic compounds (VOCs) on human health, it is crucial to determine the sources of VOCs, which can be emitted from biogenic and anthropogenic sources
In this study source apportionment was performed using positive matrix factorisation (PMF) analysis on VOC data collected at Welgegund – a regional background station located on a commercial farm approximately 100 km west of Johannesburg that is influenced by the major sources in the interior of South Africa – for more than two years
Summary
PMF analysis indicated ten meaningful factor solutions, with five factors being associated with biogenic emissions and five with anthropogenic sources.
