Freerange hens’ eggs were used for monitoring levels of contamination by POPs in various locations in many previous studies [1-6]. Eggs have been found to be sensitive indicators of POP contamination in soils or dust and are a significant exposure pathway from soil pollution to humans. Eggs from contaminated areas can readily lead to exposure which exceeds thresholds for the protection of human health [7-9]. Hens and their eggs might therefore be ideal “active samplers”: an indicator species for the evaluation of levels of contamination of sampled areas by POPs, particularly by dioxins (PCDD/Fs) and PCBs. On the basis of this 4 assumption, we have chosen a sampling of free-range hens’ eggs and their analyses for selected POPs as one of the monitoring tools within the project “Involvement of Civil Society in the Decision-making Process on Mining in Armenia” (further information about the project can be found at http://english.arnika.org/armenia,http://www.awhhe.am/, https://www.ecolur.org/.).
The data and analyses of free-range hens’ eggs discussed in this report were obtained during field visits in July 2018 as a result of the above-mentioned joint project of Armenian and Czech NGOs. A general description of the samples and of the locality they were taken in can be found in Chapter 2.
