Sea salt (ss) aerosols in PM 2.5 are often quantified through source apportionment by applying sodium (Na + ) and chloride (Cl − ) as the markers, but both markers can be substantially emitted from anthropogenic sources. In this study, we differentiate ss from nonss (nss) portions of Na + and Cl − to better apportion PM 2.5 in a coastal tropical urban environment. Size-resolved ionic profiles accounting for Cl − depletion of aged ss were applied to 162-day measurements during 2012 and 2018− 2019. Results show that the nss (likely anthropogenic) portions, on average, account for 50−80% of total Na + and Cl − in submicron aerosols (PM 1 ). This corresponds to up to 2.5 μg/m 3 of ss in submicron aerosols that can be ∼10 times overestimated if one attributes all Na + and Cl − in PM 1 to ss. Employing the newly speciated ss-and nss-portions of Na + and Cl − to source apportionment of urban PM 2.5 via positive matrix factorization uncovers a new source of transported anthropogenic emissions during the southwest monsoon, contributing to 12−15% of PM 2.5 . This increases anthropogenic PM 2.5 by ≥19% and reduces ss-related PM 2.5 by >30%. In addition to demonstrating Cl − depletion (aging) in submicron aerosols and quantifying ssNa + , nssNa + , ssCl − , as well as nssCl − therein, the refined PM 2.5 apportionment resolves new insights on PM 2.5 of anthropogenic origins in urban environments, useful to facilitate policy making.

“…23 Similar approaches to metals measurement by SP-AMS have been used by a small number of previous studies. [24][25][26][27][28][29][30][31][32][33] The SP-AMS combines conventional high resolution Aerodyne AMS measurements of real-time, size-resolved composition of nonrefractory, aerosol particles with the ability to measure refractory particles. 34 Nonrefractory aerosol particles are thermally vaporized at 600 °C using a resistively heated tungsten vaporizer while refractory particles are vaporized by a 1064 nm intracavity, continuous wave laser vaporizer.…”

“…When heavy metal-impacted wood is burned or incinerated, the metals can be released into the atmosphere in the form of fine particulate matter or gases [7]. This may pose a significant health risk to nearby populations, as inhaling metal-contaminated particulate matter can result in toxicity, particularly in children and pregnant women [8,9]. Lead toxicity, for instance, can cause a range of health effects, including damage to the nervous system, digestive problems, reproductive problems, and developmental delays [10][11][12][13].…”

A field sampling event was conducted to measure the concentrations of metals within the trunks of felled trees on a college campus east of New York City. Heavy metals, particularly chromium, were found present in the soils surrounding the sampled trees, allowing for a correlation coefficient to be calculated with soil and tree concentrations. A statistically significant Pearson correlation was found between these two concentrations among the samples. This study is aimed at providing researchers a starting point for their research a better understanding of local ecologies, prediction of future change, and dissemination of conservation efforts.
