Description
Summary:Atmospheric sampling was performed to evaluate the reliability of the filter technique in collecting ambient sulphate aerosol. Results showed that a number of compounds were not retained by a Whatman 41 cellulose filter. The portion of sulphate particles which had passed through the filter at the flow rate 2.4 m 3 per 24 h accounted for 20–35% and 50% of the total sulphate concentration in rural and urban atmospheres, respectively.
