英文摘要	In order to characterise the features of particle pollution in the Pearl River Delta (PRD) region, a 1-month intensive campaign was conducted at the rural supersite (Kaiping) in the autumn of 2008. In total, 12 new particle formation (NPF) events are identified out of 30 campaign days. The results show that in the case of higher source and sink values, the result of the competition between source and sink is more likely the key limiting factor to determine the observation of NPF events at Kaiping. One episode with consecutive NPF events in the presence of strong biomass burning plume was observed between 10 and 15 November. The elevation of particle volume concentration (6.1 mu m(3)/cm(3)/day) is due to the coaction by the local biomass burning and secondary transformation. Organics and sulphates are the major components in PM1, accounting for 42 and 35% of the mass concentration, respectively. In this study, a rough estimation is applied to quantify the contributions of diverse sources to the particle number concentration. On average, the primary emission and secondary formation provide 28 and 72% of particle number concentration and 21 and 79% of mass concentration, respectively.; Meteorology & Atmospheric Sciences; SCI(E); 5; ARTICLE; 65
