Source apportionment of PM₁₀ and health risk assessment related in a narrow tropical valley. Study case: Metropolitan area of Aburra Valley (Colombia).

ABSTRACT: This study investigates spatio-temporal variations of PM₁₀ mass concentrations and associated metal(oid)s, δ¹³C carbon isotope ratios, polycyclic aromatic hydrocarbons (PAHs), total organic carbon (TOC) and equivalent black carbon (eBC) concentrations over a half year period (from March 2017 to October 2017) in two residential areas of Medellín (MED-1 and MED-2) and Itagüí municipality (ITA-1 and ITA-2) at a tropical narrow valley (Aburrá Valley, Colombia), where few data are available. A total of 104 samples were analysed by using validated analytical methodologies, providing valuable data for PM₁₀ chemical characterisation. Metal(oid)s concentrations were measured by inductively coupled plasma mass spectrometry (ICP-MS) after acid digestion, and PAHs conc
