| dc.description | Article 16 of the Stockholm Convention (SC) requested the Conference of the Parties (COP) to evaluate the effectiveness of the Convention every four years after its entering into force. In order to facilitate such evaluation, the Conference of the Parties developed a Global Monitoring Plan (GMP). Ambient air is an important matrix for the effectiveness evaluation of the Convention because it has a very short response time to changes in atmospheric emissions and is a relatively well-mixed environmental medium and includes both chemicals in gaseous form as well as chemicals partitioned onto particles (UNEP, GMP guidance 2019). The objective of the ambient air sampling networks under the SC Global Monitoring Plan (GMP) is to obtain representative data for assessing baselines, changes over time and space and the regional and global transport of Persistent Organic Pollutants (POPs). Passive sampling provides continuous, cumulative diffusive sampling over integration periods ranging from a few months (generally 3 months) to 1 year. Passive air sampling (PAS) using a Polyurethane Foam (PUF) disk sampler is the most widely used air sampling method under the GMP and in research studies. It is used to investigate the levels, trends, and long-range transport of POPs and priority chemicals in air like other Semivolatile Organic Compounds. This is also the method used in the two rounds of UNEP/GEF POPs GMP projects. In the chemical analysis of PUF samples collected during PAS, data is expressed in mass concentration by PUF (Cpuf mass/PUF disk). Data from the chemical analyses of PUF disks is expressed in mass concentration by PUF (Cpuf mass/PUF disk) for comparability the SC Data Warehouse Template uses mass concentration in air (Cair mass/m3) as a unit of measurement. This guidance supports the conversion of data on POPs from Cpuf mass/PUF disk to Cair mass/m3 to harmonize it for reporting under the SC Data Warehouse. | en_US |
