Journal article (peer-reviewed)abstract
- The first worldwide interlaboratory assesment on persistent organic pollutants (POPs) under the Stockholm Convention was organized in the Asian/Pacific, Latin American and African regions during 2009-11.A relatively large number of laboratories reported data for the PCDDs/PCDFs and dioxin-like PCBs, especially in the Asian region. Within the Asian region, several participants used high-resolution GC/high-resolution MS systems optimized for dioxin analysis. The availibility of High-resolution mass spectrometer instrumentation is limited in the Latin America and African regions, although recently several new laboratories for dioxins have started in the Latin American region.

The need for capacity building and first results for the Stockholm convention global monitoring plan
- 2013
-
In: TrAC. Trends in analytical chemistry. - : Elsevier BV. - 0165-9936 .- 1879-3142. ; 46, s. 72-84
-
Journal article (peer-reviewed)abstract
- The Stockholm Convention on Persistent Organic Pollutants (POPs) established an effectiveness evaluation to assess the efficiency of measures taken by Parties under the Convention. Among these measures, a Global Monitoring Plan requires countries to analyze core matrices for POPs. To assist countries in setting up networks for these core matrices and to generate high-quality, comparable results, the United Nations Environment Program has implemented projects in 32 developing countries. The results demonstrate the worldwide presence of POPs in air and in humans, although at different scales.

Capacity building for persistent organic pollutant (POP) analysis in the Pacific and POP trends in the Pacific Islands
- 2013

In: TrAC. Trends in analytical chemistry. - : Elsevier BV. - 0165-9936 .- 1879-3142. ; 46, s. 173-177
-
Journal article (peer-reviewed)abstract
- This article gives an overview of activities relating to the establishment of a regional center of excellence for testing persistent organic pollutants (POPs) in the Pacific Island Region. It highlights the areas of analytical procedures that needed improvement to perform trace-level POP testing in human-breast milk. It describes the actions taken by the POP expert group of the United Nations Environment Programme (UNEP) Chemicals during inspection visits and in setting up analytical procedures and proficiency tests to achieve acceptable levels of results for testing POPs regionally. It also describes results of early studies on POPs in human-breast milk in several Pacific Island countries, which generally show relatively low levels.

Towards comparable POPs data worldwide with global monitoring data and analytical capacity building in Africa, Central and Latin America, and the South Pacific
- 2013
-
In: TrAC. Trends in analytical chemistry. - : Elsevier BV. - 0165-9936 .- 1879-3142. ; 46, s. 85-97
-
Journal article (peer-reviewed)abstract
- The United Nations Environment Program (UNEP)/Global Environment Facility (GEF) created a capacity-building initiative to support the Global Monitoring Plan (GMP) for persistent organic pollutants (POPs), in which the collection of high-quality, comparable, POPs-monitoring data from all regions is critical for the identification of time trends and regional and global environmental transport. In a series of projects involving countries in West and East Africa, the Caribbean, Latin America and the South Pacific, the study design consisted of a combination of theoretical and hands-on training provided by a pool of three expert laboratories appointed by UNEP combined with POPs analysis in all areas by expert laboratories.

First worldwide UNEP interlaboratory study on persistent organic pollutants (POPs), with data on polychlorinated biphenyls and organochlorine pesticides
- 2013
-
In: TrAC. Trends in analytical chemistry. - : Elsevier BV. - 0165-9936 .- 1879-3142. ; 46, s. 110-117
-
Journal article (peer-reviewed)abstract
- The first worldwide interlaboratory study on persistent organic pollutants (POPs) under the Stockholm Convention was organized, with a participation of 103 laboratories from Asia, Europe, the Americas, Africa and Australia, of which the majority submitted data on polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs). The participating laboratories were requested to analyze different matrices (i.e. two test solutions, and test materials for fish, sediment, fly ash and human milk). All results were statistically evaluated according to the procedures used in the European Union-based QUASIMEME proficiency-testing scheme.

POPs analysis reveals issues in bringing laboratories in developing countries to a higher quality level
- 2013
-
In: TrAC. Trends in analytical chemistry. - : Elsevier BV. - 0165-9936 .- 1879-3142. ; 46, s. 198-206
-
Journal article (peer-reviewed)abstract
- We assessed the performance of laboratories in 18 developing countries in analyzing persistent organic pollutants (POPs) in environmental and human samples, as part of a capacity-building program with the goal of helping laboratories increase proficiency in the types of analyses required for the POPs Global Monitoring Program (GMP) under the Stockholm Convention. We identified several issues that need improvement before the laboratories can contribute to the GMP, including technical aspects of POPs analysis, QA/QC issues and laboratory-management problems.
