Source Specific Chemical and Toxicological Profiles of Port-Derived Particulate Matter

Abstract

of mediators from exposed 16HBE cells. Across all samples there was significant association between PM V and Ni concentrations, and the release of multiple inflammatory mediators, and an inverse association with cell viability. These results show port-derived PM has source-related elemental profiles, enabling a future source apportionment study. Toxicological results suggest the UF fraction of shipping PM may pose a heightened risk to health.
