Aerosol characterization during the summer 2017 Huge Fire event on Mount Vesuvius (Italy) by remote sensing and In situ observations

During the summer of 2017, multiple huge fires occurred on Mount Vesuvius (Italy), dispersing a large quantity of ash in the surrounding area ensuing the burning of tens of hectares of Mediterranean scrub. The fires affected a very large area of the Vesuvius National Park and…

Gestational exposure to landscape fire increases under-5 child death via reducing birthweight: a risk assessment based on mediation analysis in low- and middle-income countries

Background Exposure to landscape fire smoke (LFS) is linked to child mortality and birthweight. It is unknown whether gestational exposure to LFS affects child survival rate. We aimed to link under-five death (U5D) to gestational LFS exposure by performing a causal mediation…
