The authors have properly addressed the comments of the two anonymous referees.
However, I have several comments that need to be addressed before this manuscript can be published in ACP.

The concentrations are expressed in µg/m3; however, it is unclear whether the air volumes used were volumes at ambient temperature and pressure or instead at standardized conditions; this should be indicated.
Lines 5-14: There are problems with the affiliation of some of the authors. For example, Kebin He is from China and not from Indonesia.
Line 33: Replace "black carbon" by "equivalent black carbon".
Line 74: Replace "et al. 1994" by "et al., 1994".
Line 84: Replace ", however" by "; however,".
Lines 126-127: Replace "black carbon" by "equivalent black carbon".
Line 142: Replace "457nm, 520nm, 634nm" by "457 nm, 520 nm, 634 nm".
Line 156: Replace "et al (2015)" by "et al. (2015)".
Line 164: Replace "burning," by "burning".
Line 179: Replace "black carbon" by "equivalent black carbon".
Line 189: First, as appears from Table 1, several more trace metals are measured than Zn, Mg, Fe, and Al; all measured trace metals should be listed here or the text should at least be modified. Secondly, Zn cannot really be called a crustal element. According to Mason (Principles of Geochemistry, 3rd ed., Wiley, 1966) the concentration of Zn in average crustal rock is only 70 ppm; there are more than 20 elements with higher concentrations in average crustal rock.
Lines 191-193: More information on the ICP-MS analysis is needed; a literature reference should at least be provided.
Line 220: Replace "associate as" by "associated as".
Line 239: The statement that "Trace elemental oxides are the summation of oxides for all measured ICP trace elements" is incorrect; Mg, Fe and Al are also determined by ICP-MS, but, according to Table 1, not included in TEO.
Line 325: Reference is made here to Sect. 4.9; however, there is no such section.
Line 362: Replace "is ongoing task" by "is an ongoing task".
Line 409: Replace "account for" by "accounts for".
Line 415: Should it not be "dependent" instead of "independent" here?
Line 417: Replace "potassium K" by "K".
Line 456: Replace "relate to" by "relates to".
Line 469: Replace "than other" by "than in other".
Line 470: Replace "to larger" by "to a larger".
Line 480: Replace "than most" by "than for most".
Line 480: Replace "than either" by "than in either".
Line 481: Replace "than Yang" by "than in Yang".
Line 482: Replace "than Oanh" by "than in Oanh.
Line 513: Replace "black carbon" by "equivalent black carbon".
Line 560: Replace "salt" by "sea salt".
Line 568: Replace "for two" by "for almost two".
Line 652: Should it not be "Science and Technology" instead of "Science" here?
Line 658: Replace "al.(2010)" by "al. (2010)".
Line 667: Replace "10m" by "10 m".
Line 687: Replace "orgnic" by "organic".
Line 689: Replace "the value" by "with the value".
Section 6.2: It is unclear at which RH the PM2.5 data of the Beta Attenuation Monitor were taken. At dry conditions (RH=35%)? If not, how were they converted to dry conditions (RH=35%)? Clarification is definitely needed.
Line 711: Acronyms and abbreviations, here "BAM", should be explained (written full-out) when first used; presumably, "BAM" stands for "Beta Attenuation Monitor".
Line 718: Replace "panel shows" by "panel in Figure 4 shows".
Lines 723-724: The sentence starting with "The agreement" is redundant; it repeats essentially what is already said in line 711.
Line 739: Replace "black carbon" by "equivalent black carbon".
Reference list (pages 21-28): Titles of journal articles should be in lower case instead of in Title Case; this comment applies, e.g., to Begum et al. (2012), Behera et al. (2010) and Bell et al. (2007), but also to several more references.
Lines 907-909: This reference should be moved down; it should come after "USEPA, 2014".
Line 1001: Replace "Sci. , 326" by "Science, 326".
Line 1168, within Table 1: It is stated in column 2 that the measurement method for the CM species is "ICP-MS & IC"; however, none of the three elements listed for CM in column 3 is determined by IC, they are measured by ICP-MS only.
Line 1176: Replace "Residue Matter" by "Residual Matter".
Page 30, footnote of Table 3: Replace "Residue Matter" by "Residual Matter".
Page 30, footnote of Table 3: It is unclear to what the "Geometric mean of ratio" applies.
Page 31, caption of Figure 1: The figure shows data for "Ammonium Sulfate" not for "Ammoniated Sulfate" (ASO4). If the figure is correct, the acronym "ASO4" cannot be used in the caption; in addition, the text in lines 289-293 would also need to be revised.
Page 33, line 2 of figure caption: Replace "residual" by "residual matter".
Page 35, within Table A1: Replace "100 nm particle" by "100 nm particles".
