Introduction The Acid Deposition Monitoring Network in East Asia (EANET) was established as an initiative for regional cooperation among the participating countries, creation of a common understanding on the state of acid deposition problems and for providing useful inputs to policy makers at various levels. Monitoring activities started during the preparatory phase activities of EANET from March 1998 to December 2000. Regular monitoring of acid deposition started from January 2001 with the participation of 10 countries, namely China, Indonesia, Japan, Malaysia, Mongolia, Philippines, Republic of Korea, Russia, Thailand, and Viet Nam. Cambodia, with Lao PDR and Myanmar joining EANET in 2001, 2002 and 2005 respectively, there are currently 13 countries participating in EANET activities. Acid deposition monitoring of EANET covers four environmental items – wet deposition, dry deposition (air concentration), soil and vegetation, and inland aquatic environment. Monitoring of wet and dry deposition has been implemented in order to measure atmospheric concentrations and to evaluate fluxes of acidic substances to the land surface, while monitoring for soil/vegetation and inland aquatic environment was carried out to assess adverse impacts on terrestrial and aquatic ecosystems. The monitoring data was used to evaluate the state of acid deposition as well as impacts on ecosystems. Participating countries are required to submit the data and related information obtained from the monitoring activities conducted at the EANET sites in their respective countries to the Network Center of EANET (NC) by the end of June of each calendar year based on the guidelines of EANET. The NC had prepared and presented a draft Data Report 2007, which contains the monitoring data from the participating countries at the Eighth Session of Scientific Advisory Committee (SAC8), held in October 2008. The draft Data Report was considered at SAC8 by the experts from participating countries. Following the comments and guidance at SAC8, NC has elaborated and finalized the report. The Data Report 2007 contains the data obtained from monitoring activities carried out in2007. CHAPTER 2 Network Description 2. Network Description 2.1 Classification of Monitoring Sites EANET monitoring sites are classified into two basic categories, namely acid deposition monitoring sites and ecological survey sites. Acid deposition monitoring sites are sites collecting fundamental data on the temporal and spatial distribution of acid deposition, and they are further classified into 3 sub-categories: remote sites, rural sites and urban sites for the objectives of the monitoring. Ecological survey sites are those that provide basic data for assessing the effects of acidification on terrestrial ecosystems, and they are further classified into 2 sub-categories: survey sites and ecosystem analysis sites. The criteria used for classification of the sites are presented in Table 2.1. Table 2.1 Classification of Monitoring Sites Site Category Site Classification Main Purpose and Siting Criteria Acid Deposition Monitoring Site for wet deposition and dry deposition monitoring Urban Site - Assessment of the state of acid deposition in urban areas - Urbanized and industrial areas, and the areas immediately outside the urban area - Data can be used for evaluation of acid deposition effect on buildings and historical monuments or human health Rural Site - Assessment of the state of acid deposition in rural areas and/or hinterlands - Data can be used for the evaluation of acid deposition on agricultural crops, forests and etc. - More than 20km apart from large pollution sources like cities, power plants and highways Remote Site - Assessment of the state of acid deposition in background areas - Data can be used for evaluation of long-range transport and deposition models - More than 50km apart from large pollution sources like cities, power plants and highways - More than 500m apart from main roads (more than 500 vehicles per day) Ecological Survey Site for soil and vegetation monitoring and Inland aquatic monitoring Basic survey site - Accumulation of b asic data on soil, forest, and inland aquatic environment and disclose trends in their properties - In the vicinity of the acid deposition monitoring site Ecosystem analysis site - Assessment of acid deposition impacts on whole ecosystem through application of terrestrial ecosystem analysis and/or catchment analysis - Sensitive Areas to changes in atmospheric acidity and ecologically conserved area 2.2 Monitoring activities in 2007 Thirteen EANET countries, namely, China, Japan, Mongolia, Republic of Korea and Russian Federation of the North-East Asian region, and Cambodia, Indonesia, Malaysia, Myanmar, Lao PDR, Philippines, Thailand and Vietnam participated in monitoring of acid deposition in 2007. Monitoring data was submitted from a total of 50 monitoring sites, including 20 remote, 11 rural and 19 urban sites. A map showing the location of these sites is provided in Figure 2.1 . The details on the location of the monitoring sites are presented in Table 2.2 . Figure 2.1 Locations of EANET Sites in 2007 (Note) “Xi’an”, “Chongqing”, “Xiamen”, and “Zhuhai” includes 2 sites, respectively. “Jakarta” includes also nearby “Serpong” and “Bandung” sites, and “Bangkok” includes also nearby “Samutprakarn” and “Patumthani” sites. “Metro Manila”/“Los Banos” and “Hanoi”/“Hoa Binh” are described as one point, respectively due to map scale. Khao Lam Dam and Vachiralongkorn Dam (of earlier Data Reports in 2000-2003) were renamed into Khanchanaburi and also Mae Hia was renamed into Chiang Mai in 2004. Danum Valley Nakhon Ratchasima Mt.
