“…Kandy is a city with heritage value, located at 519 m above mean sea level. The latitude and longitude coordinates of Kandy city are approximately 7.2914 and 80.6366, respectively [5,10,32]. It has a high population density of about 6000 persons per km 2 ; its daily transient population is around 100,000 people, and daily traffic flow is over 100 000 vehicles through four main entrances towards the city center [10,25].…”

“…Polgolla, a suburban area in the Kandy District, is located inland at 512 m above mean sea level. In this area, the average humidity is 93%, the average daytime ambient temperature is 23.7 -30.2 °C, and the monthly rainfall is 52.4 -398.1 mm [5]. Site C was located on the premises of the Mahaweli Development Authority (7.3249, 80.6420) which is very close to the left bank of the Mahaweli river adjacent to the dam of the Polgolla reservoir [Figure 2(c)].…”

“…Washout of these atmospheric constituents during precipitation delivers to the earth's surface by rain, snow, or hail is called wet deposition [3]. Bulk deposition can be referred to as the sum of both wet and dry depositions [5,6]. Rain is the most effective type of wet deposition, where liquid water falls from the sky to the surface of the earth [7].…”

“…Geographically, Sri Lanka is very close to the Indian mainland, and thus the atmospheric air quality of India could have a significant impact on Sri Lankan air quality [7,22]. In contrast to the global trend of studying the chemical composition of rainwater, only a few studies have been published in Sri Lanka [5,7,[23][24][25][26]. Some of these studies discovered the presence of acid rain during certain precipitation events.…”

The chemical composition of atmospheric deposition changes over time due to a variety of physical, chemical, and biological conditions. The objectives of this study were to use statistical methods to compare the composition of cations, anions, and water quality parameters of bulk deposition. Three sampling sites of 7 km apart in Kandy District in Sri Lanka were selected for the study: The Kandy City Center (KCC) site represented an urban environment located in a valley, the University of Peradeniya (UoP) site and the Polgolla sites represented a suburban environment. Bulk depositions were collected weekly over eight months (from 03.08.2018 to 27.03. 2019). The chemical analyses of anions (Cl-, NO3-, SO42-) and cations (Na+, K+, Ca2+, Mg2+, NH4+) in bulk depositions carried out using ion chromatography indicated that the volume-weighted mean (VWM) concentrations of cationic species in KCC, UoP, and Polgolla sites followed as, Na+> Ca2+> Cl-> K+> Mg2+> NH4+> SO42-> NO3-, Ca2+> Na+> Cl-> Mg2+> NH4+> SO42-> NO3-> K+, and Na+> Cl-> Ca2+> NH4+> K+> NO3-> SO42-> Mg2+ respectively. The VWA pH in KCC, UoP, and Polgolla sites were 6.93, 6.82, and 6.85, respectively, which are nearly neutral due to the neutralization effect. The VWA conductivity values of KCC, UoP, and Polgolla sites were 64.22 µS cm-1, 49.40 µS cm-1, and 42.66 µS cm-1, respectively. Average values of other water quality parameters (salinity, total dissolved solids, and hardness) were higher in the KCC site than those in the other two sites.
