“…In addition, comparing results of the present study with a research carried out for several cities in south-central Mexico, the Fe values observed in this study for the Universidad site (1090.8 µg L −1 ) exceed the values of all the cities monitored in the central-southern Mexico study (292 at 448 µg L −1 ). Likewise, the Cd concentration reported for cities in central-southern Mexico (1 to 4 µg L −1 ) were lower than the values reported in the present study (10 to 13 µg L −1 ), as well as the concentrations values of Cu and Mn [8]. This means that the MAM in general shows higher concentrations of Fe and Cd in rainwater compared to other Mexican cities that also have a high population load and industrialization.…”

“…The type and concentrations of chemical species in rainwater vary between locations and regions. In addition, it reflects the influence of local sources, atmospheric transport conditions, atmospheric temporal development, and its level of contamination [8]. Airmass trajectories combined with chemical composition of precipitation data provide valuable information about the origin of air pollutants.…”

Chemical Composition of Bulk Precipitation and Its Toxicity Potential Index in the Metropolitan Area of Monterrey, Northeastern Mexico

et al. 2020

The rainwater chemistry within the Metropolitan Area of Monterrey (MAM) was studied during a one-year period (January 2019–January 2020) in seven sampling sites. The metal concentration of Zn, Fe, Cd, Cu, Ni, and Mn was analyzed in bulk samples and the toxicity potential (TP) was calculated for each metal. A canonical correspondence analysis (CCA) was applied to identify the relationship between environmental variables and metals concentrations. An average of 26.6 ± 10 mm of rainfall was obtained. A mean pH of 7.2 ± 0.3 and a mean electrical conductivity of 177.8 ± 8.7 µS cm−1 were observed. The average concentration of metals in all sites follows a descending order of Fe> Zn > Mn > Cu > Ni > Cd. The university site shows the highest averages of Fe, Zn, Cu, and Mn, which is attributed to its proximity to the metallurgical industry. The TP value of Cd reflects a risk in all sites and Fe only for the Universidad, Obispado, Pastora, and Santa Catarina sites, using as a reference value the Environmental Protection Agency (EPA) Drinking Water Regulations and Mexican norm NOM-127-SSA1-1994. The CCA analysis showed that only Ni and Cd had a strong correlation with the environmental variable of relative humidity of air.

“…Similarly, Riversa‐Riversa et al. (2020) in Mexico reported high concentrations of trace metals in warm seasons. They showed that the trace metals (i.e., Zn, Fe, Cr, Cu, Pb, Ni, Co, As, and Cd) have the highest concentrations with little scavenging of pollutants from the atmosphere in March‐May (i.e., warm seasons).…”

“…However, these effects are unclear on the Lake Urmia basin. Some studies were conducted on seasonal precipitation chemistry (Akkoyunlu & Tayanç, 2003; Blew & Edmonds, 1995; Guo et al., 2014; Luo et al., 2007; Riversa‐Riversa et al., 2020). The results indicated that varying aerosol concentrations affect the microphysics of clouds and the chemical composition of precipitation changes in time and space, event by event, and season by season (Jain et al., 2019).…”

Wet Scavenging in Removing Chemical Compositions and Aerosols: A Case Study Over the Lake Urmia

et al. 2022

Lake Urmia, NW Iran, and S Caucasus region, has lost approximately three‐fourth of its water volume resulting in increased exposure of lacustrine deposits. Therefore, the role of Lake Urmia desiccated saline lands on local aerosols and rainwater compositions is still vague. This study investigates the temporal and seasonal patterns of rainwater chemistry from January 2018 to June 2018 (six months) in 13 stations throughout the Lake Urmia basin. The samples collected were analyzed using triple quadrupole inductively coupled plasma mass spectrometry (ICP‐QQQ) and ion chromatography (IC) to measure elemental and ionic concentrations. Then, the Hybrid Single‐Particle Lagrangian Integrated Trajectory model (HYSPLIT) was applied to identify the pathway and contribution of emissions. The results depict that the concentration of elemental and ionic components over different parts of the Lake Urmia basin are significantly different. West and north directions have the highest concentrations of marine ions associated with fewer toxic elements. In contrast, the east and south directions show a high concentration of heavy metal elements and ions. The high level of heavy and toxic elements at the east and south directions indicates that local anthropogenic sources are more influential. The seasonal and monthly variabilities of chemical compositions depict that the highest concentration of Na+, Mg2+, Ca2+, K+, Cl−, Br−, NO3−, Al, Cr, Mn, Fe, and Co were in the spring season and SO42−, NH4+ and NO2− were highest in winter. Seasonal variation for MSA, organic acids (i.e., Pyruvate, Adipate, and Oxalate), Ni, Cu, Zn, V, and Ti were not apparent. Cluster‐mean HYSPLIT backward trajectories results show the most dominant air mass sectors are from W (a: Iraq, Syria, and Arabian deserts; b: Mediterranean Sea; and c: KSA) and NE (the Caspian Sea and its vicinity), contributed to almost 65% and 22%, respectively. These air masses bring a significant quantity of crustal and marine aerosols, respectively. It is inferred that the Lake Urmia dried‐up lakebeds have less impact on the contribution of emissions across the region.

“…Globally, studies pertaining to geochemistry of rainwater have gained tremendous momentum primarily due to two reasons [9,29,64,73,124]. First, due to the toxicity of certain metals (such as Pb, Cd, Cr, As, Hg), their capability to bioaccumulate and biomagnify and carcinogenic properties, high concentrations of such metals in precipitation are perilous for both terrestrial and aquatic ecosystems [62,92,122]. Hence understanding the chemical composition of rainwater, particularly the pollutants are important for the environment and ecosystem.…”

India is one of the world's wettest countries receiving over 1000 mm of rainfall annually and also one of the countries experiencing regular floods and droughts. This study quantifies elemental composition of rainwater and aerosol collected simultaneously during 2019 monsoon season from Kolkata, a megacity in Eastern India marred by air pollution to understand sources and estimate wet deposition flux. Elemental composition (Na,
