The average size distributions of the species (except BC) were all dominated by an accumulation mode peaking at about 600 nm in vacuum aerodynamic diameter, and organics was characterized by an additional smaller mode extending below 100 nm. Positive Matrix Factorization (PMF) analysis of the high resolution organic mass spectral dataset differentiated the(More)
Shanghai, with a population of over 20 million, is the largest mega-city in China. Rapidly increasing industrial and metropolitan emissions have deteriorated its air quality in the past decades, with fine particle pollution as one of the major issues. However, systematic characterization of atmospheric fine particles with advanced measurement techniques has(More)
The Pearl River Delta (PRD) region in South China is one of the most economically developed regions in China, but it is also noted for its severe air pollution due to industrial/metropolitan emissions. In order to continuously improve the understanding and quantification of air pollution in this region, an intensive campaign was executed in PRD during(More)
Phencyclidine (PCP) is an antagonist of the NMDA subtype of glutamate receptor. PCP treatment induces psychosis in normal humans, which provides a valuable model of schizophrenia. PCP administration also models some of the symptoms of schizophrenia in experimental animals. NMDA hypofunction has been hypothesized to explain these schizophrenia-like symptoms.(More)
