Autor: Salvador Reynoso-Cruces, Alfonso Enrique Hernández-López, Javier Miranda, Lourdes Verónica Mejía-Ponce
Publikováno v: Environmental Pollutants & Bioavailability, Vol 33, Iss 1, Pp 334-346 (2021)
Aerosol samples (PM10 and PM2.5) were collected during the 2018-2019 dry-cold season, inside an electrostatic particle accelerator laboratory at Instituto de Física, Universidad Nacional Autónoma de México, and on the rooftop. The goal was to meas
