Spatial mapping and size distribution of oxidative potential of particulate matter released by spatially disaggregated sources
The ability of particulate matter (PM) to induce oxidative stress is frequently estimated by acellular oxidative potential (OP) assays, such as ascorbic acid (AA) and 1,4-dithiothreitol (DTT), used as proxy of reactive oxygen species (ROS) generation in biological systems, and particle-bound ROS measurement, such as 20,70-dichlorodihydrofluorescein (DCFH) assay.
