The authors have reasonably addressed the comments of the three anonymous referees.
However, I have a number of (mostly minor) comments that need to be addressed before this manuscript can be published in ACP.

For the main text:
Line 80: Replace "their source" by "its sources".
Line 99: Replace "30 min" by "30-min".
Line 124: Replace "30 minutes" by "30-min".
Line 129: Replace "70eV" by "70 eV".
Line 154: Replace "are sampled" by "was sampled".
Line 175: Replace "Briefly PMF" by "Briefly, PMF".
Line 177: Replace "to classical" by "to the classical".
Line 212: Replace "fractions>40%" by "fractions >40%".
Line 220: Replace "ACSM also" by "ACSMs also".
Line 382: Replace "guidelines given" by "guideline given".
Lines 404, 412, 415, 455, 456, and 466: Replace "night time" by "night-time".
Line 442: Replace "variations show" by "variations shows".
Line 459: Replace "the decreasing of" by "the increasing of".
Line 465: Replace "characteristics of" by "characteristic of".
Line 1052: Replace "Slopes of mass vs volume are in g/cm3 and" by "Slopes are in g/cm3 for mass vs volume and".
Line 1084: Replace "averages in" by "averages as a".
Line 1085: Replace "of events" by "of pollution events".

For the Supplementary Material:
Line 22: Replace "represents the" by "represent the".
Line 32: Replace "(Crenn et al., 2015)" by "Crenn et al. (2015)".
Line 104: Replace "for SA analysis" by "for source apportionment (SA) analysis".
Line 150, Table S2: The data in this table are hard to read; I suggest increasing the font size.
Line 185: "Kroll et al. (2011)" is missing in the Reference list.
Line 187: Replace "in function" by "as a function".
Line 188: Replace "2 events" by "2 pollution events".

Short summary

Atmospheric particulate matter (PM) levels and resulting impacts on human health are in the Po Valley (Italy) among the highest in Europe. This study discusses submicron PM chemical composition, sources and atmospheric processes in this region, using state-of-the-art measurement techniques and receptor models. Based on these results, effective PM abatement strategies are suggested in the upper Po Valley.
