2.2 Station siting criteria
AS/NZS 3580.1.1 contains general guidelines br the siting 01 ambient air quality monitoring equipment, providing siting parameters for a number of air pollutants. AS/NZS 3580.14 contains guidelines for the siting of meteorological monitoring equipment, specifically for ambient air quality monitoring applications.
In practice, an ideal site satisfying all criteria is rarely achieved. Consequently, non-conformance with the provisions of AS/NZS 3580.1.1 and AS/NZS 3580.14 does not invalidate data generated at the monitoring site. Non-conformances shall however be noted in the data report so that a user of the data can make their own assessment on its suitability for their purposes (see Clause 3.2).
2.3 Sample handling, storage and archiving
2.3.1 Sample handling and storage
Physical ambient air quality samples can be affected by extremes of temperature, ultraviolet light, atmospheric pressure, the presence of other pollutants and physical handling.
For transportation, all samples should be placed in suitable containers to protect from breakage, contamination and loss, and, if the samples have specific temperature requirements, inside a temperature controlled device. Samples should be delivered to the laboratory for analysis as soon as possible after collection, preferably on the same day. Where storage is required, samples shall he stored in accordance with the relevant Standard.
The number of transport containers should be recorded on a chain of custody form, together with identification numbers for all samples. The analytical laboratory should confirm that all listed samples were included in the shipment. In order to verify that sample transport temperatures conform to method requirements, sensors capable of measuring maximum and minimum temperatures should be placed in each shipping container and the resultant data recorded upon sample receipt.
Sample handling and storage requirements for each Standard that entails sample collection, together with the action to be taken if the requirement is not met, shall be as set out in Table 1.
All Standards describing manual particulate matter monitoring methods specify the maximum period between sampling and final filter weighing. Non-conformance with sample storage and handling requirements described in the relevant Standard shall be noted in the data report, together with a data qualifier (flag) noting the actual period between sampling and final weighing, together with an explanation for the non-conformance. However, data shall not be invalidated on this basis.
Where storage requirements specified in the Standard relate to the period between sampling and sample extraction, sampling and subsequent analysis (other than gravimetric) or sample extraction and analysis (e.g. AS/NZS 3580.9.15, AS/NZS 3580.13.2 and AS/NZS 3580.16), non-conformance can result in the data being either flagged or invalidated.
For AS/NZS 3580.9.15 non-conformance with the maximum storage period shall be noted in the data report, with a data flag noting the actual period between sampling and filter extraction and an explanation for the non-conformance.
For AS/NZS 3580.13.2 and AS/NZS 3580.16, non-conformance with the maximum storage periods results in the data being invalidated, unless the reporting organization can provide data which supports an extended storage period (or higher storage temperature in the case of AS/NZS 3580.16), in which case the evidence shall be appended to the data report, together with associated data flags indicating non-conformance with this Standard. For AS/NZS 3580.16, evidence shall include confirmation that the field surrogate compound recoveries are within the specified range (see Table 5).AS 3580.19 pdf download.
