| Description | Kosetice observatory is a facility of the Czech Hydrometeorological Institute which is a part of European Monitoring and Evaluation Programme (EMEP) network. Persistent organic pollutants (POPs: PCBs, DDTs, HCHs, PAHs) have been monitored in all environmental matrices using the integrated monitoring approach. Generally, the atmospheric levels of POPs in this Central European background station (mean values: 0.115 ng m-3 for PCBs, 0.040 ng m-3 for DDTs, 0.077 ng m-3 for HCHs, and 17 ng m-3 for PAHs) are significantly higher than those in other EMEP stations localized mostly in Northern and Western Europe. Long-term trends of POP concentrations in the ambient air and wet deposition are presented in this article and they show a slow decline in the last decade for most of investigated compounds. A temporally increased levels of certain chemicals were associated with some local climatic (floods) or socio-economic (fuel prices) factors. |
