Περίληψη:
Fires in urban and natural ecosystems cause catastrophic consequences on a global scale.
Concern is raised as it has been observed that the remaining materials after the fire, contain
metals, including heavy metals in high or toxic levels[1]. The aim of the present research is to
investigate the influence of urban fires on the concentration of mobile forms of such elements
of concern and heavy metals in surface and in different soil depths. Sampling of soils of
pyrogenic origin was carried out in 2022. At least 800 different ground sampling points were
selected according to operating standards in the territory of Mati and Kineta (Attica, Greece).
Both suffered from wildfires in July of 2018. The heavy metals content of the soil samples was identified after Aqua Regia extraction. Inductively coupled plasma-mass spectrometry (ICPMS) was used as analytical method [2]. Due to its high sensitivity and low detection limit twelve metals were measured (i.e., Al, Cr, Mn, Co, Ni, Cu, Zn, As, Cd, Sn, Hg, Pb). Certified Reference
Materials (CRM) were used for the method development. The results were evaluated using
the Dutch List, a collection of values and regulations related with the contaminated soils[3].
