**About the Editors**

**Pasquale Avino** is Associate Professor at the University of Molise in the field of analytical chemistry and environmental chemistry. After obtaining his doctorate in Chemical Sciences at the University of Rome "La Sapienza", he completed his professional training at the University of California, Irvine (USA), with Prof. F.S. Rowland (Nobel Prize in Chemistry in 1995) where he was interested in air pollution and related problems connected to sampling in remote areas (the South–East area of the Pacific Ocean) and at high altitudes (mountains and transoceanic air flights). He is the author or co-author of more than 160 peer-reviewed papers according to the Scopus database; he has coordinated several research projects in the environmental sector. He works in the context of regulatory proposals on air pollution for the transposition of EU directives on air quality by actively participating in national commissions on this issue. He is a member of several scientific associations/societies. For his studies, he received the NASA Award and the Sapio National "Environment and Health" Award.

**Gaetano Settimo** is a researcher on air pollution (indoor and outdoor) at the Italian National Institute of Health (ISS). His degree is in Industrial Chemistry and he has a Ph.D. in Environmental Engineering. His working experience has been carried out in the area of environmental research, with a particular focus on the impact of chemical pollution on the environment and human health, and on the evaluation of exposure and risk assessment. This experience also includes the study and implementation of analytical methods for measuring certain pollutants that may occur in industrial and urban areas, and the evaluation of emissive sources and possible mitigation measures. He is in charge of various research groups and is currently coordinator for the National Study Group on Indoor Pollution established by the ISS. He belongs to various ministerial working parties regarding risks linked to the Environment and Health.
