Persistent Organic Pollutants (POPs) in Chicken Eggs from Alaverdi, Armenia

In this study, we present the results of the monitoring of free-range hens’ eggs from Alaverdi, a town in the north of Armenia, close to the border with Georgia, which was considered to be potentially contaminated by persistent organic pollutants (POPs).

Introduction

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.
