“…The second source was enriched with SO 4 2- and NO 3 - ( Fig 9B ), indicating a fossil fuel combustion source. The two icons were associated with NO x emitted from coal-fired power plants, residential heating and cooking, and motor vehicles [ 39 ]. The third source had a high loading of Ca 2+ and Mg 2+ , representing a crustal or windblown dust source ( Fig 9C ).…”

Atmospheric nitrogen (N) deposition (Ndep), an important component of the global N cycle, has increased sharply in recent decades in China. Although there were already some studies on Ndep on a national scale, there were some gaps on the magnitude and the spatial patterns of Ndep. In this study, a national-scale Ndep pattern was constructed based on 139 published papers from 2003 to 2014 and the effects of precipitation (P), energy consumption (E) and N fertilizer use (FN) on spatial patterns of Ndep were analyzed. The wet deposition flux of NH4+-N, NO3--N and total Ndep was 6.83, 5.35 and 12.18 kg ha-1 a-1, respectively. Ndep exhibited a decreasing gradient from southeast to northwest of China. Through accuracy assessment of the spatial Ndep distribution and comparisons with other studies, the spatial Ndep distribution by Lu and Tian and this study both gained high accuracy. A strong exponential function was found between P and Ndep, FN and Ndep and E and Ndep, and P and FN had higher contribution than E on the spatial variation of Ndep. Fossil fuel combustion was the main contributor for NO3--N (86.0%) and biomass burning contributed 5.4% on the deposition of NO3--N. The ion of NH4+ was mainly from agricultural activities (85.9%) and fossil fuel combustion (6.0%). Overall, Ndep in China might be considerably affected by the high emissions of NOx and NH3 from fossil fuel combustion and agricultural activities.

“…The third source had a high loading of Ca 2+ and Mg 2+ , representing a crustal or windblown dust source ( Fig 9C ). The profile also contained a significant SO 4 2- indicating a great effect of neutralizing the acid [ 39 ]. The fourth source was dominated by NH 4 + suggesting an agricultural source ( Fig 9D ).…”

“…To investigate the chemical composition of rainwater in the study area, physicochemical parameters, trace metals and major ions were considered within this work. Adopting the well-established approach of rainwater quality investigations as reported in the literature (see Li et al 2011;Alam et al 2012;Huston et al 2012;Amponsah et al 2015;Morales-Pinzón et al 2015;Mimura et al 2016;Bharti et al 2017;Majumdar et al 2020), physicochemical parameters, that is, pH, electrical conductivity (EC), total dissolved solids (TDS), alkalinity, hardness and turbidity, trace metals such as Fe, Cu, Zn, Pb, Mn, Cr and Cd and major ions, that is, NO 3 À , SO 4 2À , PO 4 3À and NH 4 þ were selected and measured in this study. The analytical parameters and method for assessing water quality of rainwater samples are provided in Supplementary Table S1.…”

The chemical characteristics of rainwater in the south-eastern region of Bangladesh were investigated in this study in addition to identifying the potential sources of different precipitation constituents, which have often been unexplored or not well covered in the literature. Rainwater pH, major ions and trace metals were measured in samples collected from five different locations with different land-use patterns of the Chattogram Metropolitan area (CMA) during two rainy seasons. The results of this study showed variability in rainwater quality across the sites signifying site-specific influences. The mean concentration of all measured physicochemical parameters, ions and trace metals in rainwater samples was also found to be significantly lower compared with the drinking water quality standard of Bangladesh and WHO guidelines. The correlation matrix and principal component analysis (PCA) indicated that and originated from anthropogenic sources, while the average concentration of trace metals found in rainwater was exhibited in the following order: Zn>Cu>Fe>Cr>Mn>Pb>Cd. The findings of this study could be used as a reference to further investigate the influences of industrial, urban and agricultural emissions that regulate the chemical characteristics of the atmosphere in particular areas of study.

Calculating air mass trajectories is common in atmospheric analyses. However, if explainable results are to be achieved, several procedures are needed to process the vast amount of information handled. Clustering methods are statistical tools usually considered for such a purpose. Although they are based on rigorous algorithms, certain questions still remain when these methods are applied. The current review is organised in sections according to the sequence followed by such procedures. First, the types of clustering methods are described, with their core being the distance used. One key point is the stopping rule, which determines the final number of clusters. A simple classification based on this number is then suggested. Finally, the graphical presentation of the results is examined and the main drawbacks are commented on. A range of applications and results are considered to illustrate each section, and certain caveats and recommendations are also presented.
