Abstract

In order to investigate the precipitation chemistry, studies were carried out from January 2013 to December 2013 in Odorheiu Secuiesc and Miercurea Ciuc, Eastern Carpathians, Romania. During a period of eleven years (2006 – 2016), 2013 was the driest year. The rainwater samples were analyzed for pH, major anions and cations. HCO3 concentrations were calculated based on the empirical relationship between pH and HCO3 . NH4 +, Ca2+, SO4 2− were the dominant ions in precipitation at both sites. The pH values varied from 6.75 to 7.46 Miercurea Ciuc, and from 6.69 to 7.67 in Odorheiu Secuiesc. The neutralization was mainly brought by Ca2+ and NH4 +. Estimated ratios of sea-salt fraction (SSF), non-sea-salt fraction (NSSF), and results from Spearman’s rank correlation and Principal Component Analysis (PCA), showed that the acidic ions (SO4 2−, NO3 ) were derived from anthropogenic activities, NH4 + from soil fertilization, while Ca2+, Mg2+, K+ originated from terrestrial source. These influence the precipitations ionic content, especially during droughts. Spatial variations and the rim effect of the Eastern Carpathians on precipitation chemistry is also shown.

Abstract

Trend analysis for potential evapotranspiration (PET) and climatic water balance (CWB) is critical in identifying the particulate matter concentration (PM10) variations. The PET is computed based on the monthly average temperature for the Ciuc basin using Thornthwaite parameterization. The highest levels of evapotranspiration appear during the months of May and June. The lowest levels of particulate concentration characterize the period during April-June. Precipitation is highest during May and June. Particulate matter in the highest cloud water is 0.014 µg/m3/mm during April and 0.010 µg/m3/mm during May. One can observe a significant level of negative correlation between particulate matter concentration, the potential evapotranspiration and precipitation.
