Methods for sampling and analysis of ambient air Determination of particulate matter - Deposited matter - Gravimetric method
Standards Australia
Specifies a gravimetric method for determining deposited particulate matter and metals that rapidly settle from the air.
This Standard sets out a method for the sampling of particulate matter that is deposited from the atmosphere, and procedures for the gravimetric determination of the mass deposition rate of insoluble solids, ash, combustible matter, soluble solids and total solids from ambient air.
The method provides an estimate of the mean surface concentration of deposited matter settling from the air over a sampling period, typically one month. Particulate matter deposition rates of 0.1 g/m2 month and above may be determined using a monthly sampling period.
The sample obtained by the sampling procedure specified may be subjected to physical or chemical analysis. A method to determine deposition rates for metals present in deposited matter is provided in Appendix A of this Standard.
