Title: Apportionment of air pollution sources with directional sampling size segregation and soluble/total elemental determination of air particlates in Hong Kong

Abstract

With an aim to improve the identification of pollution sources, to enhance the ability to resolve source types and to assist the interpretation of results, a computer controlled sampling station has been developed for directional sampling and size segregation of air particulates collected using a High Volume Sampler running at a flow rate of 40 cfm. A given set of criteria was monitored by the microcomputer to stop sampling during raining and calm period (<0.5 ms{sup -1}), and to start the pump when more than 60% of the wind direction data are within the designated sector. Two size fractions of the particulates were collected (coarse, 3.0-10 um, and fine, M 3.0 um) daily with a net sampling time of 16-24 hours. Elemental analysis was performed on the particulates sampled for their total and soluble contents using FTIR for the PAHs, Capillary Electrophoresis and DC Arc Plasma Emission Spectroscopy for soluble and total anion and cation analysis.
