The Acid Deposition Monitoring Network in East Asia (EANET)’s fellowship program aims at funding researchers from the EANET’s participating countries to carry out research pertaining to acid deposition at the Network Center in Japan. Ekaterina Zhigacheva, from Russia, was awarded the EANET fellowship in 2017. She led her research on the investigation of atmospheric input and runoff discharge of sulphur and nitrogen compounds as the balance components of Komarovka river catchment by long-term observations at the Russian EANET Primorskaya station (for 2005 – 2015).


The impact of acid deposition on rivers

Air pollution consists of significant amounts of compounds of sulphur and nitrogen. These compounds deposit on the earth’s surface through wet and dry depositions and cause detrimental impacts on the ecosystems and environment, including acidification of the water bodies, such as rivers and lakes.

Zhigacheva, in this study, analysed the components of the Komarovka river catchment at Russian EANET Primorskaya station using observations from 2005 to 2015. The goal of the study was to evaluate the effects of pollution on regional ecosystems.


The author acknowledged the help received from the EANET Primorskaya site and PCEM laboratory for data and financial support and facilities from the Asia Centre for Air Pollution Research (ACAP) for performing the research.
