Size-Resolved Redox Activity and Cytotoxicity of Water-Soluble Urban Atmospheric Particulate Matter: Assessing Contributions from Chemical Components.

The highest percentages of WSOC (50–61%) were observed in the finest particle fraction (<0.49 μm), at all sampling periods, with a decreasing trend towards larger particles (12–29%; >3 μm fraction) ( Figure 1 a).

The HULIS mass distribution in the various particle fractions demonstrates the same pattern as WSOC with an increasing trend from the highest to the smallest fractions ( Figure 1 c).
