More than a week after the fire, there is no decrease in the area near the Pastorano waste disposal plant (Caserta) concentrations of micropolluting particles, such as dioxin and furans. This emerges from the note from Arpac – the fourth issued since the fire – which continues to monitor, with two high-flow samplers, the air around the site where a large quantity of material such as plastic went up in flames, which also released a toxic cloud during the fire.
As already reported in the bulletin of September 8, today Arpac also explains that "although in sharp decline, the trend of these micropollutants remains above the reference values". Better data relating to the hourly concentrations of PM10 and PM2.5 fine dust, carbon monoxide, ozone, benzene, toluene, xylene, nitrogen oxides, whose measurement is entrusted to a mobile laboratory installed by Arpac near the site of the fire; on September 8, 9 and 10, "there were no exceedances of the legal limits for these pollutants", Arpac attests.
“We continue to record – observes the Environmental Agency – hourly peaks of pollutants such as benzene and nitrogen dioxide, which however, based on the available meteorological information, do not appear to be clearly attributable to the event in question. Only between 20 and 22 pm on 9 September, hourly peaks of PM10, up to 75 micrograms per cubic meter, occurred with ventilation coming from the fire area”.
