Combination of UNMIX, PMF model and Pb-Zn-Cu isotopic compositions for quantitative source apportionment of heavy metals in suburban agricultural soils

open access: yesEcotoxicology and Environmental Safety, 2022
Quantitative identification of heavy metals (HM) sources in soils is key to prevention and control of heavy metal pollution. In this study, UNMIX, PMF (Positive matrix factorization) model and Pb-Zn-Cu isotopic compositions were combined to ...

Atmospheric Deposition Of Heavy Metals In Toronto [PDF]

open access: yes, 2021
Atmospheric deposition rates of heavy metals (As, Cd, Co, Cu, Hg, Mn, Ni, Pb, and Zn) were determined from July 2009−December 2010 in downtown Toronto. Atmospheric deposition samples were collected using samplers with plastic, glass and water surfaces from two rooftops (15 m and 59 m above ground) in the city core of Toronto.
