Abstract

The Toxic Organic Micro Pollutants (TOMPs) Network, which has operated since 1991, currently collects ambient air samples at six sites across England and Scotland, using high-volume active air samplers. Lancaster University has been operating this UK Department of Environment, Food and Rural Affairs (Defra) funded network from its inception, delivering long-term ambient air trend data for a range of Persistent Organic Pollutants (POPs) at both urban and rural locations. Data from the network provides Defra with valuable information on emission/source controls and on the effectiveness of international chemicals regulation. It is also used to demonstrate UK compliance with its obligations under the 2001 Stockholm Convention on Persistent Organic Pollutants and the 1998 UN/ECE Long-Range Atmospheric Transport Protocol. Moreover, long-term analysis of air pollutants at trace levels allows detailed studies on atmospheric fate and behaviour processes of persistent chemicals and is the inevitable basis of their successful modelling. The target chemicals of TOMPs have been polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and, since 2010, polybrominated diphenyl ethers (PBDEs). PCBs, PCDDs, PCDFs, and selected PBDEs are all listed under the Stockholm Convention. The continuous monitoring of these compounds has demonstrated the constant decline in their UK air concentrations over the last decades. The concentrations of all compounds are generally significantly higher at urban compared to semi-rural and rural sites, with estimated clearance rates between 2 and 9 years for PCBs at all sites, 2 to 4 years for PBDEs at urban and semi-rural sites, and 4 to 5 years for PCDDs and PCDFs at urban sites. All these data are in good agreement with emission estimates. Additionally, an archive is maintained, which can be used for analysing emerging chemicals, such as alternative flame retardants, pesticides, and further substances of interest as soon as they have been identified.
