The Pearl River Delta Regional Air Quality Monitoring Network - Regional Collaborative Efforts on Joint Air Quality Management

Abstract

In November 2005 the Guangdong and Hong Kong governments established the Pearl River Delta regional air quality monitoring network ("PRD RAQMN"), which represented the first joint regional air pollution and reporting effort in this rapidly developing and heavy-polluted area in southern China. This project has recorded the air quality trends during the 11 th Five-Year Plan (FYP), implemented between 2006 and 2010, and will continue to do so throughout the period of economic development and stringent emission control of coal-fired power plants and vehicles that are part of the 12 th FYP, to be implemented between 2011 and 2015. The PRD RAQMN serves as a role model for cooperation among local administrative authorities, as well as for the joint prevention and management of air pollution. The PRD RAQMN demonstrates that regional collaboration is critical to address the air pollution problems that China faces in a more effective manner.

Assessment of regional air quality resulting from emission control in the Pearl River Delta region, southern China

“…Air quality monitoring data (SO 2 , NO 2 , O 3 , and PM 10 ) were collected from the PRD Regional Air Quality Monitoring Network (Zhong et al, 2013b). The network consists of 16 sites with 13 sites in mainland PRD and 3 sites in Hong Kong, which adequately reflect the spatial patterns of air quality in the PRD region.…”

Pollution Properties of Water-Soluble Secondary Inorganic Ions in Atmospheric PM2.5 in the Pearl River Delta Region

“…The site was heavily influenced by the intense air pollutant emissions from Guangzhou and Foshan area in spring, autumn and winter (Zhong et al, 2013;Peng et al, 2014).…”

“…However, simultaneous on-line measurements of water-soluble ions of PM 2.5 and related precursor gases (HNO 3 , SO 2 and NH 3 ) are still very rare , and seasonal variations of them has not been reported in this region. In this study secondary water-soluble inorganic ions, including SO 4 2-, NO 3 -and NH 4 + in PM 2.5 , and the related gaseous pollutants including HNO 3 , NH 3 , SO 2 and NO 2 were measured simultaneously at a regional atmospheric supersite in the PRD region of Guangdong Province (Zhong et al, 2013) during four different seasons. The goal of this study was to understand the inter-action of the secondary water-soluble ions and their gaseous precursors and thus to reveal the pollution properties of the secondary inorganic ions in the PRD region, providing scientific support for designing effective fine particle pollution control strategies.…”

Measurements of Peroxyacetyl Nitrate at a Background Site in the Pearl River Delta Region: Production Efficiency and Regional Transport

“…In recent, several measurement studies have also been carried out in China, over which there is an increasing concern of air quality accompanying its fast economic development (e.g., in Lanzhou, Zhang et al, 2009a;Beijing, Liu et al, 2010;Zhang et al, 2011;Xue et al, 2014a). The Pearl River Delta region (PRD) including the adjacent Hong Kong is a hot spot of economic development and air pollution in southern China (Zhong et al, 2013). Previous studies have demonstrated the severity of the photochemical smog problem in this region (Zhang et al, 2007;Zhang et al, 2008;Xue et al, 2014b).…”
