Pallas, AMAP station, Northern Finland

Updated 2013-01-26

The overall objectives for operation of the station will follow those defined in the AMAP programme. The main interests are the levels and trends of airborne toxic pollutants (POPs and heavy metals) in northern Fennoscandia.

This is a National Implementation Plan (NIP) project

Methods & Procedures

Procedures and methodology used for, e.g., sampling and sample storage, sample pretreatment, extraction and analysis, including which laboratories are involved, references to methods employed, etc.

POPs: The POPs in the air are collected using a high volume air sampler (HVS). A glass fiber filter is used for trapping the particles followed by an adsorbent of polyurethane foam (PUF) for collecting compounds in the gas phase. Both wet and dry deposition of POPs is collected using an open sampler (bulk sampler). This sampler consists of a 1 m2 Teflon coated surface with edges. The bottom declines slightly to a central opening where a cassette with an adsorbent of PUF is attached. The deposition sample includes both compounds in the precipitation and compounds deposited to the collection surface of the sampler. The POPs are extracted from the sample matrix with solvent extraction and prior to the analysis a selective preparation of the sample extracts is undertaken. Laboratory: The sample treatment and analysis of POPs are done at IVL, Göteborg. Mercury: Precipitation samples for mercury are collected in special samplers. Samples for particulate mercury in air are collected on filters. Gaseous mercury in air is sampled in gold traps. Analysis: Cold vapour AAS. Laboratory: IVL, Göteborg Heavy metals: Bulk samples of precipitation. Filter samples for heavy metals are collected with a medium-volume sampler. Analysis: ICP-MS. Laboratory: Finnish Meteorological Institute. Acidifying compounds: Bulk precipitation samples for major ions. Filter sampling for sulphate, sulphur dioxide, nitrate+nitric acid, ammonium+ammonia. The methods are from the EMEP manual. Laboratory: Finnish Meteorological Institute (FMI).
