Malagrotta fire, no dioxin alarm ” within WHO reference values ​​”

The dioxin values ​​are within the limits established by the WHO. This is what emerges from the monitoring of Arpa Lazio relating to two air samplings, after the Malagrotta fire. ” The value of the first sample – emphasizes Arpa Lazio – is lower than the reference value identified by the WHO for the urban environment (0.2 pg / m3 compared to the WHO reference value between 0.1-0.3), the value of the second sample is equal to the reference value identified as indicative of the presence of a local emission source ” (0.3 pg / m3).
