Particulate matter levels are high in Mati, affected by a deadly fire on July 23, but below danger levels, according to updated environmental tests by the Demokritos Research Center released on Friday.
Preliminary tests on the particulates also showed that the concentrations of heavy metals ? chromium, cadmium, nickel, lead and arsenic ? are below danger levels.
According to the tests, the levels of particulates fluctuate, with the heaviest concentration occurring between 8:00 a.m. and 5:00 p.m., when work to restore the town is being carried out.
Demokritos set up sampling stations 150 meters from the shore at Mati on August 11. Between that date and September 3, the particulates in the area reached 29.5 micrograms per cubic meter of air (+/- 6.3) compared to the Attica basin baseline, as measured at Demokritos’ premises in Agia Paraskevi, of 17.2 μg/m3 (+/- 5.6).
The level of soot is normal and comparable to urban areas. At Mati it was 0.9 μg/m3, compared to 0.7 μg/m3 in Agia Paraskevi.
