It is our pleasure to invite you to the

4th ICP Forests Scientific Conference

"Long-term trend and effects of air pollution on forest ecosystems, their services, and sustainability"

that will be held in Ljubljana, Slovenia, from 19-20 May 2015.

Main topics include:

• The temporal development (possibly with predictions) of air pollution effects on forests, including nitrogen deposition and ozone impacts, on different spatial scales

• Temporal and spatial development of forest performance indicators, forest ecosystem services, their sustainability and interactions with climate trends

• Integrative analyses and modeling exercises based on the above indicated data

The Conference will bring together scientists and experts from ICP Forests, the UNECE ICPs community under the Working Group on Effects (WGE), partners and respective stakeholders, as well as interested scientists and…

Dear colleagues,



the results of the 17th Needle/Leaf Interlaboratory Test are available on the FFCC homepage. The qualification reports can be downloaded from the ringtest web-interface. You had to login here with your lab code and your password. The following ICP-Forests laboratories (=laboratories analysing monitoring samples from the vegetation period 2014) had to re-qualify for some parameters:

A47: C

A60: Pb

F06: S, P, Mg

F24: P, K, C

F28: Mg

F29: Ca, Mg, Zn, Cu, Cd

Please, keep in mind that the requalification for ICP-Forests laboratories  must be finished before 1st of September…

In 2010–2012, an extensive study was performed in forest sites of Mount IDA (Kazdagi)/Edremit 26 years after the Chernobyl accident. The 137Cs activity concentrations were determined by gamma-ray spectrometry in the forest soil layers (OL, OF + OH and A horizons) separately. Based on 341 surface soil samples and 118 soil profiles, activity concentrations of 137Cs in OL horizons varied between 0.25 ± 0.14 and 70 ± 1 Bq kg−1, while the ranges of 137Cs activity concentrations in OF + OH and A horizons were 13 ± 1–555 ± 3 Bq kg−1 and 2 ± 1–253 ± 2 Bq kg−1, respectively. Cesium-137 deposition in the study area was estimated to be in the range of 1–39 kBq m−2 and a linear relationship between the deposition of 137Cs and the altitude was observed. The distributions of 137Cs activities in OL, OF + OH and A horizons throughout the region were mapped in detail. The highest 137Cs activities were found in OF + OH horizons, with markedly lower 137Cs activity in mineral horizons of soil profiles.… Continue
