Online single particle measurement of fireworks pollution during Chinese New Year in Nanning.
Time-resolved single-particle measurements were conducted during Chinese New Year in Nanning, China. Firework displays resulted in a burst of SO2, coarse mode, and accumulation mode (100-500nm) particles. Through single particle mass spectrometry analysis, five different types of particles (fireworks-metal, ash, dust, organic carbon-sulfate (OC-sulfate), biomass burning) with different size dis...
متن کاملRegulatory effects on particulate pollution in the early hours of Chinese New Year, 2015
Human activities are a key driver of air pollution, so it is hardly surprising that celebrations affect air quality. The use of fireworks contributes to high particulate concentrations in many parts of the world, with the Chinese Lunar New Year (spring festival) particularly noticeable, as firecrackers are traditionally used to drive off evil spirits. Fireworks lead to short-term peaks in the c...
متن کاملThe Characteristics of Air Pollutants during Two Distinct Episodes of Fireworks Burning in a Valley City of North China
BACKGROUND The elevation and dissipation of pollutants after the ignition of fireworks in different functional areas of a valley city were investigated. METHODS The Air Quality Index (AQI) as well as inter-day and intra-day concentrations of various air pollutants (PM10, PM2.5, SO2, NO2, CO, O3) were measured during two episodes that took place during Chinese New Year festivities. RESULTS F...
متن کاملSingle-Particle Characterizations of Ambient Aerosols during a Wintertime Pollution Episode in Nanning: Local Emissions vs. Regional Transport
Ambient aerosol during a heavily polluted episode in wintertime was characterized using real-time single particle aerosol mass spectrometry (SPAMS) in urban Nanning, a capital city in the Southwestern China. More than two million individual particles analyzed by SPAMS were classified into 8 major clusters based on the mass spectral patterns. A group of vanadium-rich particles were identified as...
متن کاملBased on e-Business technology to construct logistics information service platform of renewable resources - - Taking Nanning city as an example
With the rapid development of economy and the increase of population, we are facing the stern challenge of lack of resources and environment pollution. Through the recycling of resources we can reduce the exploitation of native resources and save energy. At present, the level of recycling resources in Nanning city is quite low, as do the utilization rate of recovery. The recyclable resource log...
