Pesticide contamination of bee products is a widespread phenomenon. Due to its composition, bread affected by both lipophilic and hydrophilic substances. As proof concept monitoring campaign better understand the extent contamination, we developed an analytical method based on modified QuEChERS extraction, with subsequent separation liquid chromatography detection mass spectrometry. This allowed for quantitation 51 agricultural- or beekeeping-associated pesticides in bread. The workflow was...
Mesomediterranean vegetation with abundant evergreen broadleaved trees and shrubs is dominant along the coast of northern Greece. Well-dated palynological records are available from inland submediterranean zone, where absent or rare, but less known about history coastal area. For instance, it unclear when why expanded during Holocene. Here we present a new record mesomediterranean site, Limni Volvi, near Aegean Sea. To understand Holocene history, combined palynology, microscopic charcoal...
The importance of the stable isotopes in tree rings for study climate variations caused by volcanic eruptions is still unclear. We studied δ18O, δD, δ13C larch and cembran pine cellulose around four major with annual resolution, along a superposed epoch analysis 34 5-year resolution. Initial tropical Tambora (1815 CE) Samalas (1257 showed post-eruption decrease δ18O values attributed to post-volcanic cooling increased summer precipitation Southern Europe, as documented observations...
