“…In addition, we excluded volcanic activity as a potential source of excess sFe, considering that it would not have affected the chemical composition of aerosol samples, as mentioned above. The potential Fe sources are distinctly divided into three groups according to the Al, K, and V concentrations in aerosols from previous studies: high K/Al and low V/Al (Group 1: biomass burning and steel plant), ,− low K/Al and high V/Al (Group 2: heavy fuel oil), ,, and low K/Al and low V/Al (Group 3: crust, solid waste, coal, and road dust) ,− (Figure a). In Group 1, higher K concentrations are generally observed in biomass burning and steel plants because K is abundant in the cytoplasm of the plant , and is a major component of recycled materials used in the main process of steel plants, such as sintering. ,, Additionally, Group 1 can be divided into two subgroups according to the type of biomass burning and the process of steel plants (Group 1–1: agricultural biomass burning and sintering dust from steel plant; Group 1–2: woody biomass burning and nonsintering dust from steel plant).…”

Iron (Fe) is an essential micronutrient for phytoplankton growth, and its availability limits primary production in half of the global ocean. Traditionally, atmospheric input of natural mineral dust has been considered as a main source of Fe in the surface ocean. However, here we show that about 45% of the water-soluble Fe in aerosols collected over the East Sea (Japan Sea) is anthropogenic, which originates mainly from heavy fuel oil combustion, based on the analyses of various chemical tracers (Al, K, V, Ni, Pb, and 210 Pb). It is striking that a tiny quantity of oil, less than 1% of the aerosols in mass, can constitute the majority of water-soluble Fe in aerosols due to its high Fe solubility. Furthermore, we show that a quarter of dissolved Fe in the East Sea is anthropogenic using a 210 Pb-based scavenging model. Since this sea is almost fully enclosed (200−3000 m) and located at the forefront of the Asian human footprint, our results provide an insight that the marine Fe cycle may be already perturbed by human activities.

“…Looking at the sample case of incineration of agricultural waste, among the previous studies on biological combustion for estimating the emission factor, the research on incineration of agricultural residues [40] collected a total of 15 samples in 5 repetitions, and the research on meat roasting [41] collected and analyzed 3 samples as in the relevant previous studies [42,43]. In this study, 3 samples in repetition were collected.…”

Illegal open burning, which is criticized as a leading source of air pollutants among agricultural activities, currently requires constant effort and attention from countries around the world. A speciation analysis method is required to examine the harmful effects of particulate matter generated by incineration on the human body. In this study, to simulate open-air incineration, infrastructure for incineration tests complying with US EPA method 5G was built, and a large-area analysis was conducted on the particulate matter through automated SEM-EDS. For test specimens, waste mulching LDPE collected by Korea Environment Corporation Dangjin Office was used. To raise the identifiability of analyzed particles, the specimen was sampled on a plate made of Ag, which has a high atomic number, three times. Metal particulate matter showed a high reaction to C and C-O. The ratio of metal particulate matters that reacted to C and C-O was in the order of Cu (94.1%) > Fe (83.3%) > Al (79.7%). In this study, it was verified that waste mulching adsorbs metal chemicals originating from the soil due to its properties and deterioration, and that when it is incinerated, it emits particulate matter containing transition metals and other metals that contribute to excessive ROS production and reduction.

“…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].…”

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.
