Abstract

Ambient hydrocarbon air pollution levels at both industrial and non-industrial sites in South Africa were determined over a period of six months.

Passive samplers and evacuated canisters were used during these surveys to capture the sample, while gas chromatography/mass spectrometry was used for the analysis of 40 volatile hydrocarbon compounds. Benzene levels found at both semi-electrified residential and industrial sites emphasized the nee
