High-Spatial-Resolution Population Exposure to PM2.5 Pollution Based on Multi-Satellite Retrievals: A Case Study of Seasonal Variation in the Yangtze River Delta, China in 2013

open access: yesRemote Sensing, 2019
To assess the health risk of PM2.5, it is necessary to accurately estimate the actual exposure level of the population to PM2.5. However, the spatial distribution of PM2.5 may be inconsistent with that of the population, making it necessary for a high ...

Analysis on PM2.5 transport trajectories and potential pollution source for Wenzhou area(温州市PM 2.5输送轨迹特征和潜在污染源区分析)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2015
利用HYSPLIT模式和全球再分析资料模拟2012~2014年温州市大气输送的后向轨迹.结合聚类分析方法、潜在源贡献因子分析法、浓度权重轨迹分析法得到分季节的温州大气输送轨迹、污染潜在源区以及潜在源区污染浓度.温州地区春、秋、冬季节容易受西北、偏北、西南等内陆气流影响,来自偏北、西南方向的短轨迹由于移动缓慢、扩散能力差,PM 2.5的浓度值高;夏季主要受较为清洁的海洋性气流影响,PM 2.5的浓度值低.影响温州的潜在污染源区主要集中在3块区域:西北及中原地区、华北地区和江西-福建-浙江周边区域.其中西北、

Characteristics and sources apportionment of water-soluble ions in PM2.5 of Wenzhou, Zhejiang Province(温州市PM2.5中水溶性离子污染特征及来源分析)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2017
2015年1~12月在温州市区采集448个PM2.5样品,采用离子色谱法分析PM2.5中9种水溶性离子(、Cl-、Na+、K+、Ca2+、Mg2+和F-)的浓度,研究其污染特征、化学组分和来源.采样期间9种水溶性离子总浓度为39.97 µg • m-3,和占所测水溶性离子总量的(40.19±10.04)%.离子总浓度的季节变化特征为冬季>春季>秋季>夏季,从空间分布上看,多数季节市站采样点PM2.5中离子总浓度低于南浦、龙湾和瓯海采样点.相关性分析结果显示,PM2.5值与、Ca2+、Na+、K+、Cl-、
